 Is Amazon actually giving you the best price? This little known plugin reveals the answer. Managing a healthy weight and lifestyle can make it easier to control a thyroid condition and keep thyroid hormones in the blood within normal levels. Appetite swings are both a cause and effect of levothyroxine and weight loss. Some argue that a decreased appetite may cause the weight loss, whereas other evidence supports theories that the weight loss caused by this synthetic hormone in turn causes a counteracting increase in appetite as the body attempts to sustain sufficient weight. Although both increased and decreased appetite are reported with the use of this drug, levothyroxine and weight loss are more strongly correlated than levothyroxine and weight gain. Levothyroxine is available only by prescription due to the possibility of several severe side effects. Those experiencing any of the symptoms associated with hypothyroidism should consult with a medical professional to discuss this potential disorder. Hypothyroidism can dramatically affect a person's mental and physical health, often decreasing quality of life and impairing lifestyles. A physician or health care provider may run a variety of tests, including hormonal measurements to better determine if a person is suffering from a thyroid disorder.

Levothyroxine is a synthetic thyroid hormone prescribed to treat low thyroid function, also known as hypothyroidism. Low thyroid function slows down the metabolism and this can lead to weight gain. Taking levothyroxine to treat hypothyroidism can help to normalise metabolism which may lead to weight loss. Levothyroxine contains a boxed warning saying that it should not be used for the treatment of obesity or weight loss. Taking levothyroxine for weight loss when not indicated can cause overdose symptoms. These symptoms include nervousness, insomnia, emotional swings, sweating, hand tremor, hair loss, sensitivity to warm temperatures (feeling hot all the time), muscle weakness, shortness of breath, heart failure and angina, confusion and disorientation. Periods may stop. Stroke, shock, coma and death have been reported as symptoms of overdosage. The best way to lose weight is to cut back calories and increase activity, especially aerobic activity, to burn stored fat. For more information on weight loss visit:

 One person with a specific gut microbiome may differ significantly in terms of weight loss/gain from a particular food – than a person with a different gut microbiome. It may be necessary to consider that administration of synthroid may alter a person’s gut microbe in such a way as to promote weight loss. Metabolism increase: The primary reason synthroid users experience weight loss is related to an increase in basal metabolic rate (BMR). As was already discussed, individuals with hypothyroidism tend to exhibit abnormally slow basal metabolic rates. When synthroid is taken, basal metabolic rate is corrected (or normalized) and weight loss occurs without much effort. This may result in weight loss without any change in lifestyle, dietary intake, etc. When you’re burning more energy at rest as a result of an increase in basal metabolic rate (compared to pre-synthroid treatment), weight loss is likely to occur. Neurochemistry: There is evidence to suggest that synthroid (levothyroxine) affects neurotransmission and neural activation (of particular regions).

 Levothyroxine and weight loss are indeed correlated in that a common adverse effect of this drug is loss of appetite and weight. This medication is a synthetic of the hormone it strives to mimic — thyroxine. It is primarily used in the treatment of numerous thyroid conditions. Of all conditions related to the thyroid, hypothyroidism is the most common ailment in which levothyroxine is prescribed. The prefix hypo generally means under or less, which translates hypothyroidism into not enough thyroid action. Specifically, this condition describes the inability of the thyroid to produce enough thyroid hormones. Levothyroxine, by simulating thyroxine, acts to fill the void of insufficient production. Side effects of levothyroxine may include insomnia. The effects of hypothyroidism are broad and varied, ranging from insignificant to life threatening depending on the severity of diagnosis. Among the symptoms are fatigue, depression, and weight gain.

 Most patients not only prefer to take Natural desiccated thyroid (medication that includes T3 hormone) but this medication also results in more weight loss and an improved quality of life. One of the biggest problems with T4 only medication is that your body may NOT be converting it to the active T3 thyroid hormone. In many patients, your body may actually convert it to reverse T3 thereby slowing your metabolism, and actually making your condition and symptoms WORSE. But here is another important note side note: Natural Desiccated Thyroid still contains T4 (in fact the majority is still T4).
That means that sometimes NDT can actually make hypothyroid symptoms worse as well by increasing reverse T3. People with this problem need pure T3 medications like Liothyronine to improve symptoms and lose weight. You can read more about case studies using NDT with T3 medications here.
What to do if you think Levothyroxine is Causing Weight Gain
If you have constantly gained weight (or even if you just aren't losing weight) there are several steps you can take to figure out if the dose of thyroid medication you are taking is working in your body. You can find a guide on how to properly dose Levothyroxine here.

T4 to T3 Conversion Matters... A lot
Before we talk about how Levothyroxine and Synthroid can cause weight gain we need to talk about some basic thyroid physiology. Your thyroid, under the influence of TSH (if working properly), pumps out primarily the thyroid hormone T4. What you need to understand is that T4 is an inactive hormone.

I am 63 and on 88mcg of Levothyroxine. I am finding it hard to lose weight too, despite exercising and diet. I lost 20 lbs on WW in 2009 b/4 being on the pills, and put on weight only after I started taking thyroid pills. You'd think I would have LOST, not gained, weight. In the past 4 mos. or so I didn't step on the scale until New Year's Day.

If you just started l evothyroxine and you are wondering about side effects, I know what you are worried about: Is levothyroxine actually working for me? Why do I still feel bad if I'm on thyroid medication? How long will it take for me to start feeling BETTER? Are my new symptoms caused by levothyroxine? Why am I still gaining weight on thyroid medication? Are these symptoms normal? If you fall into any of these categories don't worry, because I'm going to go over each one of them.

About Dr. Westin Childs
 Does getting on medication help at least a little bit? Yes, but not a lot. If you are going to lose weight after getting on Synthroid or levothyroxine it will only be about 5-15 pounds at most. That's because the thyroid usually only contributes that much to your total weight. If you are 50+ pounds overweight then 15 pounds may be from your thyroid, 30 may be from insulin resistance, 10 may be from estrogen levels or cortisol levels, etc. Weight gain and weight loss are much more complex than just eating less and exercising more and hoping that everything will "work itself out". The bottom line? If you are going to lose weight when you add Synthroid or levothyroxine it will only be a small amount IF the medication is right for you. What's more is that due to other mechanics in your body, the addition of T4 only medications like Synthroid and levothyroxine can actually lead to weight GAIN. It may not make sense now, but we are going to discuss below how that happens.

Suzanne's first comment is right on. Weight gain is not a normal side effect of taking levo and too much of it could cause weight loss, the opposite of what you report. Your doc should get involved.

What Is Levothyroxine Used For?
An Overview of Levothyroxine Uses
Levothyroxine Uses for Hypothyroidism
 However, sometimes too much of the thyroid is destroyed, leaving people with an underactive thyroid (which will need to be treated with thyroid hormone replacement, such as levothyroxine). Whatever the cause, the end result is the same -- the thyroid does not produce enough thyroid hormones, which can result in the following symptoms of hypothyroidism: Weight gain
Fatigue and weakness
Feeling cold all the time
Hair loss and/or coarse, dry hair
Skin that is dry, rough, and pale
Constipation
A decreased sex drive
Muscle cramps
Changes in the menstrual cycle
Depression
Irritability
Memory loss. As you can see, many of these symptoms can be subtle, and many people blame their symptoms on aging or stress, without realizing they have a thyroid problem. Because the symptoms are subtle and because hypothyroidism can be detected with a simple and inexpensive blood test, healthcare providers recommend that most adults be tested periodically. Levothyroxine works to boost the body's thyroid hormone levels, which can work wonders for the symptoms of hypothyroidism. However, do not expect results overnight; it often takes several weeks to notice any improvement. Levothyroxine should never be used to increase energy or cause weight loss in people without a thyroid problem. It is important to understand that with levothyroxine, more is not necessarily better.

About Dr. Westin Childs
 Less heat = colder body temperatures = slow metabolism
But that isn't the only way that hypothyroidism can cause weight gain. Believe it or not, your thyroid also influences other hormone systems in your body. Here's an example of what can happen to your hormones when you have hypothyroidism: Progesterone levels may fall leading to estrogen dominance and weight gain in the hips, butt, and thighs (low progesterone may also contribute to infertility)
Cortisol levels increase causing weight gain in the abdomen
Insulin levels increase leading to abdominal fat
Leptin levels may increase causing weight loss resistance
Testosterone levels may change as sex hormone binding globulin falls
So what happens is as thyroid hormone falls you get hit with a double whammy: Hypothyroidism leads to a slowing of your metabolism and causes other hormone imbalances which then lead to further weight gain. The big problem is that simply fixing your hypothyroidism by replacing thyroid hormone with Synthroid or levothyroxine does NOT fix the other hormone problems. It may resolve your hypothyroid symptoms like hair loss, fatigue, and brain fog - but it usually doesn't lead to weight loss. Why? Because the other hormone problems still persist! But what about the weight gain from hypothyroidism itself?

Are you on the thyroid medication Synthroid and not losing weight? If so you aren't alone...
Synthroid is one of the most commonly prescribed medications for patients who have hypothyroidism but here's the problem: Not everyone does well on this medication. Their bodies don't absorb it, they don't convert T4 to T3 or they need more T3 due to other problems. Despite this, almost every patient is given Synthroid, levothyroxine or other T4 medications and many of you are still dealing with weight issues. And I want to share with you some reasons why that may be the case. It turns out that the thyroid is certainly involved in maintaining your metabolism and can lead to weight gain if you are hypothyroid - that much is true. But did you know that simply replacing thyroid hormone in your body with medications like levothyroxine and Synthroid often isn't enough to help you lose weight? In this post, I'm going to talk about the reasons why Synthroid isn't helping you with weight loss and what to do about it. More...

Rather strangle that Levothyroxine has reported as one its side effects an increased appetite, along with weight loss, weight gain was not reprted. However, if you do think it could be one of its rare side effects, do please ask your doc to change your med. Please do take care, best wishes! Votes: +1

About Dr. Westin Childs
 This isn't to say that it will have this effect in every person, because that's certainly not the case. In fact, most people do still need some T4 medication, the problem is that they also need pure T3 medication and most Doctors don't frequently prescribe T3 containing medications. The amount of T3 that you need depends generally on how many chronic medical problems you have or how sick you are. The sicker the patient, the more T3 they generally need. If your plan is to take Synthroid or levothyroxine for weight loss and you aren't hypothyroid then you are most certainly out of luck. Because even if you have hypothyroidism it's NOT likely to cause significant weight loss by itself (6), except for certain circumstances. Studies have shown that even taking suppressive doses of LT4 (levothyroxine) to lower the TSH does NOT result in weight loss. But this study did show that lowering the TSH did slightly increase the basal metabolic rate of women, but not enough to normalize free T3 levels. How Long Before Synthroid Helps with Weight Loss? So why is it that some people are able to lose weight on Synthroid while other patients don't lose any weight and some very unlucky patients actually gain weight on it?

I guess it can cause weight gain ... it is known to cause an increase in appetite. ( However, the side effects also say it can cause weight loss). If is has caused increase in appetite for you then it surely will cause weight gain. Votes: +0

You are probably on 125 mcg (micrograms) or 1.25 mg (milligrams), not 125 mg (milligrams) per day. The average FULL REPLACEMENT DOSE of levothyroxine sodium is about 1.7 mcg/kg/day (e.g., 100-125 mcg/day (or 1 - 1.25 mg/day) for a 70 kg adult (154 lbs)).

Suzanne's first comment is right on. Weight gain is not a normal side effect of taking levo and too much of it could cause weight loss, the opposite of what you report. Your doc should get involved. You're more likely than not still HYPOthyroid and may need more levo. Read comments on the second website with extreme caution and recall these are coming from laymen. Some I read are frankly off the wall yet are rated 'helpful' by other uninformed lay persons. I'd rate this site as potentially dangerous and unhelpful unless you have sufficient medical knowledge to allow you to discriminate between useful info and utter nonsense. PT

Levothyroxine can interfere with the absorption of other medications. Levothyroxine is a synthetic thyroid hormone prescribed to treat low thyroid function, also known as hypothyroidism. Part of your endocrine system, your thyroid gland is located at the base of your throat and creates the hormones that control how quickly you use both oxygen and energy -- the basis of your metabolism. A sluggish thyroid doesn't produce enough hormones; as a result your metabolism slows down -- which can easily lead to weight gain. Once you begin to take levothyroxine, your metabolism will normalize and weight loss should be easier. Metabolism and Weight Loss
Weight loss with hypothyroidism can be challenging because a slower metabolism results in fewer calories being used.

 Synthroid (levothyroxine) can cause you to lose weight as a side effect, but should never be used for weight loss. Pros and cons of Synthroid (levothyroxine)
Pros
Works well to replace low thyroid hormone levels in your body
Safe to use for all ages and during pregnancy
Affordable, generic version is available
Only needs to be taken once a day
Most side effects are dose-related, and will go away when the dose is lowered

You'll need routine blood tests to make sure you are on the right dose of Synthroid (levothyroxine). Missed doses can cause symptoms of hypothyroidism, such as fatigue, weight gain, increased sensitivity to cold, constipation, and dry skin
Cannot be used in people with untreated adrenal insufficiency
Should not be used to treat conditions not associated with abnormal thyroid function (like benign thyroid nodules, nontoxic diffuse goiter, swelling of thyroid gland caused by infection)
Pharmacist tips for Synthroid (levothyroxine)
Most of the side effects are symptoms of hyperthyroidism and it usually means your dose is too high. If you have any of the listed side effects, talk to your provider; they might need to lower your dose. Unlike other medications, not all generic forms of Synthroid (levothyroxine) are the same. Try to fill this medication at the same pharmacy every month and pay attention to the manufacturer. You might not be able to change the manufacturer the pharmacy uses, but you can talk to your provider about changing your dose if needed. Don't stop taking Synthroid (levothyroxine) without talking to your provider first. They might need to lower your dose gradually.

Synthroid (Levothyroxine) & Weight Loss: The Research
How much weight will you lose while taking synthroid (levothyroxine)?
Does everybody lose weight while taking synthroid (levothyroxine)?
Have you lost weight while taking Synthroid (levothyroxine)?
 During treatment with synthroid, the body receives a synthetic version of thyroxine (T4) which upregulates the hypothyroid-induced metabolic downregulation and facilitates weight loss. Users that are prescribed an optimal dosage of synthroid should lose all weight that was gained specifically as a result of their hypothyroidism. Weight loss from synthroid is usually most prominent during early stages of synthroid treatment because the body hasn’t yet adapted to the increase in basal metabolic rate (BMR). Other content on MentalHealthDaily.com
Report this Ad
As synthroid treatment is continued for an extended duration, the body will have adjusted to the increase in basal metabolic rate (BMR), and additional weight loss will subside. For some users, weight loss may subside after a few months of treatment, yet for others it may take a year for the weight loss to diminish. The amount of weight loss that occurs from synthroid, as well as how quickly it occurs, will likely be contingent upon how long you lived with untreated hypothyroidism and the severity of your hypothyroidism. How Synthroid (Levothyroxine) May Cause Weight Loss
There are many possible ways in which synthroid may contribute to weight loss. In most cases, weight loss resulting from synthroid usage should be chalked up to the fact that it corrects an abnormal and/or dysfunctional basal metabolic rate (BMR) associated with hypothyroidism. It is the correction of BMR (by promoting an increase) that leads to weight loss. Other ways in which synthroid may cause weight loss include:

During treatment with synthroid, the body receives a synthetic version of thyroxine (T4) which upregulates the hypothyroid-induced metabolic downregulation and facilitates weight loss. Users that are prescribed an optimal dosage of synthroid should lose all weight that was gained specifically as a result of their hypothyroidism. Weight loss from synthroid is usually most prominent during early stages of synthroid treatment because the body hasn’t yet adapted to the increase in basal metabolic rate (BMR).

As synthroid treatment is continued for an extended duration, the body will have adjusted to the increase in basal metabolic rate (BMR), and additional weight loss will subside. For some users, weight loss may subside after a few months of treatment, yet for others it may take a year for the weight loss to diminish. The amount of weight loss that occurs from synthroid, as well as how quickly it occurs, will likely be contingent upon how long you lived with untreated hypothyroidism and the severity of your hypothyroidism.

Hyperthyroidism

 When you have hypothyroidism, some of your body functions start to slow down. This can cause fatigue, dry skin, hair loss, weight gain and feeling cold. Doctors diagnose hypothyroidism by checking thyroid-stimulating hormone (TSH) and thyroxine (T4) levels in the blood. Hypothyroidism is usually treated and controlled with thyroid hormone therapy using levothyroxine (Synthroid, Eltroxin). This drug replaces thyroxine, which is normally made by the thyroid. It may take some time to find the right dose so you don’t have symptoms of hypothyroidism. Doctors will adjust the dose of levothyroxine based on blood test results. Hyperthyroidism
Hyperthyroidism is when the thyroid makes too much thyroid hormone. It can be caused by Graves’ disease (an autoimmune disease of the thyroid), thyroid nodules, thyroiditis, an enlarged thyroid (called goitre) or too much iodine in your diet. Hyperthyroidism can cause nervousness, sleep problems, increased appetite, weight loss, feeling hot, frequent bowel movements and a rapid or irregular heartbeat.

Does getting on medication help at least a little bit? Yes, but not a lot. If you are going to lose weight after getting on Synthroid or levothyroxine it will only be about 5-15 pounds at most. That's because the thyroid usually only contributes that much to your total weight. If you are 50+ pounds overweight then 15 pounds may be from your thyroid, 30 may be from insulin resistance, 10 may be from estrogen levels or cortisol levels, etc. Weight gain and weight loss are much more complex than just eating less and exercising more and hoping that everything will "work itself out". The bottom line? If you are going to lose weight when you add Synthroid or levothyroxine it will only be a small amount IF the medication is right for you. What's more is that due to other mechanics in your body, the addition of T4 only medications like Synthroid and levothyroxine can actually lead to weight GAIN. It may not make sense now, but we are going to discuss below how that happens.

 It is recommended that you NOT alter brands with no prior consultation from your doctor. Certain medications, such as colestipol, cholestyramine, antacids, colesevelam, simethicone, sucralfate, sodium polystyrene sulfonate, iron, orlistat and calcium carbonate can reduce the quantity of thyroid hormones that is in the body. In case you are consuming any/some of the above mentioned drugs, split them from Levothyroxine by a minimum of 4 hours. Indications of a stumpy thyroid hormone level includes muscle pains, tiredness, constipation, gain in weight, dry skin, sensitivity towards cold and a slow heartbeat. Inform your doctor case your state worsens or continues after quite a few weeks of consuming Levothyroxine. Side Effects of Levothyroxine

An Overview of Levothyroxine Uses
Levothyroxine Uses for Hypothyroidism
 However, sometimes too much of the thyroid is destroyed, leaving people with an underactive thyroid (which will need to be treated with thyroid hormone replacement, such as levothyroxine). Whatever the cause, the end result is the same -- the thyroid does not produce enough thyroid hormones, which can result in the following symptoms of hypothyroidism: Weight gain
Fatigue and weakness
Feeling cold all the time
Hair loss and/or coarse, dry hair
Skin that is dry, rough, and pale
Constipation
A decreased sex drive
Muscle cramps
Changes in the menstrual cycle
Depression
Irritability
Memory loss. As you can see, many of these symptoms can be subtle, and many people blame their symptoms on aging or stress, without realizing they have a thyroid problem. Because the symptoms are subtle and because hypothyroidism can be detected with a simple and inexpensive blood test, healthcare providers recommend that most adults be tested periodically. Levothyroxine works to boost the body's thyroid hormone levels, which can work wonders for the symptoms of hypothyroidism. However, do not expect results overnight; it often takes several weeks to notice any improvement. Levothyroxine should never be used to increase energy or cause weight loss in people without a thyroid problem. It is important to understand that with levothyroxine, more is not necessarily better.

Adrenal deficiency
Any allergy, counting allergy to any food, dye, or preservative. Diabetes
Osteoporosis

Furthermore, let your doctor know in case you are: Planning on having a baby or are already pregnant
Breastfeeding
Make certain that you inform your doctor of all/any other medicines that you are prescribed to take, including the non-prescription and prescription drugs, herbals supplements and vitamins. Specific Safety Measures and Warnings
In order to steer clear of any Levothyroxine side effects, one must pay attention to the following warnings and safety measures: Levothyroxine must not be taken to take care of thyroid nodules or goiters if you have a problem of low levels of thyroid-stimulating hormones (TSHs), seeing that it may perhaps cause hazardous side effects. A squat TSH level will signal that the thyroid hormone level is by now high and adding a Levothyroxine drug may perhaps cause it to augment to a perilous level.

 So, nighttime is better. Taking levothyroxine on the day of the blood test will have an effect of a few percent on the result. However, you should leave at least a couple of hours before taking the blood otherwise it can give a misleading result. If the blood is being taken early morning I would take the levothyroxine afterwards. shaws Administrator 4 years ago
Welcome to our forum and I am really sorry your daughter, at such a young age, has to cope with hypothyroidism. First, weight gain is a clinical symptom of hypothyroidism and my personal view is that dieting isn't the way to go, if thyroid hormones are the root cause of weight gain. I shall give you a link about all of the clinical symptoms. We read (if not hypo) that exercise etc to raise metabolism will help with weight loss plus dieting. Considering that hypothyroidism has lowered our metabolism so much that weight is gained (not by everyone but is a very common complain). We really don't want to lower it further by dieting.

 And in states such as these, your body will turn T4 into reverse T3 as a way to "put on the brakes" and slow down your metabolism and cause symptoms of hypothyroidism. How Levothyroxine Causes weight gain
So how does this all relate to Levothyroxine and weight gain? We can look at some studies to help us understand: Take for instance this study. ( 1)
Patients in this study were given T4 only medications and treated based on their TSH. The researchers tested their resting energy expenditure (this is a way to test for basal metabolic rate or metabolism) both before they added the thyroid hormone and after they suppressed the TSH. Do you know what they found? It showed that patients taking thyroid hormone (even doses that lower the TSH to <0.1) did NOT have an increase in metabolism or a change in their body weight.
This is really interesting information and it has profound implications for treatment...
For one it shows that our reliance upon TSH as a marker for managing thyroid medication and function is not very accurate.
Don't get discouraged because there are other thyroid medications that actually do help with weight loss which we will discuss below.

An underactive thyroid, also known as hypothyroidism, causes your thyroid gland to underproduce thyroxine. As a result you may experience weight gain, joint pain, heart disease and infertility, according to"The Everything Health Guide to Thyroid Disease." Your doctor will prescribe thyroid replacement hormones to restore balance, which can also reduce your weight by increasing metabolism. Unithroid, Levoxyl and Synthroid are variations of levothyroxine, a synthetic thyroid hormone, according to the Mayo Clinic. Thyroid medication should only be used if you suffer from a thyroid disorder; using it with a normally functioning thyroid is ineffective and can cause life-threatening disorders. Levoxyl
This synthetic thyroid medication helps restore thyroid function and prevent goiters.

Synthroid (Levothyroxine) & Weight Loss: A Common Experience
Synthroid (Levothyroxine) is among the most popular pharmaceutical medications in the United States; over 120 million prescriptions were filled for the drug within the past year. It is a synthetically engineered form of thyroxine (T4), an endogenous thyroid hormone produced by follicular cells within the thyroid gland. Among individuals diagnosed with hypothyroidism, the body is unable to produce adequate T4 (thyroxine) via the thyroid gland, which has deleterious effects upon DNA transcription, protein synthesis, and a multitude of neurophysiological processes. As a result, individuals with hypothyroidism often exhibit symptoms such as: cognitive deficits, depression, dry skin, fatigue, malaise, and weight gain. Regular administration of synthroid (levothyroxine) is thought to reverse the aforementioned symptoms of hypothyroidism and improve functionality of the user. After several months of properly-dosed synthroid, users often report:

 Don't let your doctor convince you that you are hyperthyroid when you have crushing fatigue, weight gain, hair loss and constipation - it just doesn't work that way and you can't tell someone they are hyperthyroid based on their TSH alone. Here is another very interesting study (2) that compared people taking Natural Desiccated Thyroid to those taking Levothyroxine: This study showed that patients taking Natural Desiccated Thyroid (Like Armour thyroid, Nature-Throid, and WP Thyroid) experienced more weight loss and HALF of the people in the study said that they preferred taking NDT over levothyroxine. And here is another very important study (3) comparing equivalent dosing (based on pituitary function and TSH) of T4 medication vs T3 only medication: This study showed that patients who were taking T3 only medication had more weight loss and better cholesterol than patients who were taking T4 only medication (like Synthroid and Levothyroxine). What's also important is that the patients who took T3 did not have any change in blood pressure, heart rate or insulin sensitivity. Meaning the T3 only thyroid medication was tolerated very well. So now we have several different studies showing that patients not only do VERY well on medications containing T3 thyroid hormone but that these medications are also WELL tolerated. You can read more about the use of T3 only medication (Liothyronine and Cytomel) for weight loss here. Moral of the story?

 Among individuals diagnosed with hypothyroidism, the body is unable to produce adequate T4 (thyroxine) via the thyroid gland, which has deleterious effects upon DNA transcription, protein synthesis, and a multitude of neurophysiological processes. As a result, individuals with hypothyroidism often exhibit symptoms such as: cognitive deficits, depression, dry skin, fatigue, malaise, and weight gain. Regular administration of synthroid (levothyroxine) is thought to reverse the aforementioned symptoms of hypothyroidism and improve functionality of the user. After several months of properly-dosed synthroid, users often report: clearer thinking, increased energy, mood improvements, and perhaps most noticeably – weight loss. Weight loss is often among the most discussed synthroid side effects due to the fact that nearly everyone wants to look good and maintain a healthy physique. Additionally, many individuals had gained a significant amount of weight prior to using synthroid (as a result of hypothyroidism), a condition which slows metabolism. When metabolic processes are corrected as a result of synthroid, users end up losing weight and the weight loss comes as a pleasant surprise. Synthroid (Levothyroxine) and Weight Loss:

But, for this reason (and many others) I generally don't recommend using T4 only medications (like Synthroid and Levothyroxine) to treat hypothyroidism and I recommend against using the TSH to dose your medication. What's more: This study also showed that suppressing the TSH did NOT result in adverse side effects. Enter your text here...
One of the main reasons Doctors are afraid to increase thyroid medications is because they are concerned that the low TSH will result in damage to the body over time. It's not uncommon that patients will start to feel better when their thyroid dose is increased, only to have all those symptoms come back again when they are told their dose is "too high".

 When you have hypothyroidism, some of your body functions start to slow down. This can cause fatigue, dry skin, hair loss, weight gain and feeling cold. Doctors diagnose hypothyroidism by checking thyroid-stimulating hormone (TSH) and thyroxine (T4) levels in the blood. Hypothyroidism is usually treated and controlled with thyroid hormone therapy using levothyroxine (Synthroid, Eltroxin). This drug replaces thyroxine, which is normally made by the thyroid. It may take some time to find the right dose so you don’t have symptoms of hypothyroidism. Doctors will adjust the dose of levothyroxine based on blood test results. Hyperthyroidism
Hyperthyroidism is when the thyroid makes too much thyroid hormone. It can be caused by Graves’ disease (an autoimmune disease of the thyroid), thyroid nodules, thyroiditis, an enlarged thyroid (called goitre) or too much iodine in your diet. Hyperthyroidism can cause nervousness, sleep problems, increased appetite, weight loss, feeling hot, frequent bowel movements and a rapid or irregular heartbeat.

What is Hypothyroidism? Hypothyroidism refers to an underactive thyroid. It can result from insufficient thyroid hormone production or because thyroid hormones are inactivated before they have time to work ( 1 ). Left untreated it can cause many health issues including fatigue, hair loss, poor memory and weight gain. Summary: In hypothyroidism, the level of active thyroid hormones is lower than what is needed to maintain good health.

Synthroid should never be used to help you lose weight. Normal doses of Synthroid, which will keep your levothyroxine levels in your body within the normal range, will not cause you to lose any weight. Weight loss only occurs if you take excessively high doses of Synthroid, but these doses can cause serious side effects because of too much levothyroxine in the body. These side effects are particularly likely to occur if you are taking weight loss medications that contain sympathomimetic amines, which are commonly found in appetite-suppressants. Show More

 But what does this mean for you? It means you will need to take thyroid medication each morning and you will need to evaluate your blood work every 6-12 weeks to make sure you are getting sufficient thyroid hormone replacement. Negative side effects related to thyroidectomy tend to occur due to the problems with thyroid hormone replacement. The issue here is that most Doctors take a very standardized approach to thyroid hormone replacement. They tend to treat with Synthroid or Levothyroxine and adjust dosing based on the TSH . This is the conventional thought and way of treatment, but more recent studies have come out which show that optimizing thyroid treatment based on the TSH alone may cause low free thyroid hormone concentrations in the serum. This low free thyroid hormone concentration in the serum may be one of the causes of depression, weight gain, hair loss, fatigue and so on that many patients experience after the procedure. Studies are clear that patients who undergo a thyroidectomy often gain around 15 pounds on average after the procedure (5). If you go into your procedure overweight then you are much more likely to gain weight after the procedure. If you are normal weight going into the procedure then you have a much lower risk of gaining weight afterwards.

About Dr. Westin Childs
 The big problem is that simply fixing your hypothyroidism by replacing thyroid hormone with Synthroid or levothyroxine does NOT fix the other hormone problems. It may resolve your hypothyroid symptoms like hair loss, fatigue, and brain fog - but it usually doesn't lead to weight loss. Why? Because the other hormone problems still persist! But what about the weight gain from hypothyroidism itself? Does getting on medication help at least a little bit? Yes, but not a lot. If you are going to lose weight after getting on Synthroid or levothyroxine it will only be about 5-15 pounds at most. That's because the thyroid usually only contributes that much to your total weight. If you are 50+ pounds overweight then 15 pounds may be from your thyroid, 30 may be from insulin resistance, 10 may be from estrogen levels or cortisol levels, etc.

Ready for a more personal experience with your meds?
 If the dose of levothyroxine is too low, you may experience such symptoms as: Fatigue
Lethargy

Dry skin
Poor memory
Weight gain
If the dose of levothyroxine is too high, you may experience symptoms of hyperthyroidism, which include: Irritability
Sweating
Palpitations
Tremors
Diarrhea
Weight loss
Levothyroxine is known as a narrow therapeutic index drug, meaning there is a small window of effectiveness in regard to dose. It is important to stay on the same generic manufacturer of levothyroxine to reduce the variability between products. If your pharmacy is switching manufacturers of levothyroxine, be sure to speak with them about your concerns. Benadryl (Diphenhydramine) Information
Benadryl (diphenhydramine) is a first-generation antihistamine, and has a short duration of action (~4 to 8 hours) and, for most individuals, has significant sedating effects. Benadryl is most often used for the treatment of allergies and as a nighttime sleep aid. In fact, it is a common ingredient in over the counter sleep products such as ZzzQuil. Benadryl begins to work about 20 to 30 minutes after taking by mouth and maximum blood concentrations are reached after 1 to 2 hours. Benadryl is generally well tolerated but can cause the following side effects:

Well, without a clinical evacuation it would be difficult to determine the cause of your symptoms. Phentermine would not directly cause acne but secondary hormonal/ endocrine changes could possibly be responsible, though this does not sound like acne.

Weight loss tips for hypothyroid patients
Conclusion
References
 Scientists were surprised to discover that only a few studies looked into the relationship between levothyroxine medication and weight loss in the hypothyroid patient. This is, indeed, surprising if we bear in mind that overweight/obesity are common in hypothyroidism. One would expect more studies to be conducted on this subject. Modest weight loss or lack of it in hypothyroid patients who receive treatment with levothyroxine isn’t only due to the drug itself. The outcome depends on the severity of hypothyroidism, treatment adequacy, and a subsequent calorie intake of an individual [7]. The Synthroid dose can depend from one patient to another and it is important to establish the right dosage. At the same time, your lifestyle matters too and whether you eat a well-balanced diet or not. Remember, making healthier lifestyle choices isn’t only about weight management in hypothyroidism, but prevention of complications such as high cholesterol and potential cardiovascular events. It is also important to mention that weight gain or weight loss is among a number of potential side effects of Synthroid use [8]. Of course, different people have different experiences and just because someone else may have gained weight due to the medication it doesn’t mean you will too.

But here is the interesting thing: If hypothyroidism causes weight gain, then why doesn't replacing thyroid hormone with Synthroid or levothyroxine cause weight loss? ( in the majority of patients)
Why is it that patients who have their thyroid taken out gain around 15-20 pounds on average despite being treated with thyroid hormone to a normal TSH? Either we don't really understand the true function of thyroid hormone in the body, or we don't understand how to replace thyroid hormone correctly... or both.

synthroid
 If it's levothyroxine, it's a T4 med, if it's liothyronine, it's a T3 med which is almost never prescribed by itself and should never be used for a weight loss supplement. I remember you from the Weight Loss and Dieting Community. Your fear of weight gain requires counseling. Read More
I take oral iron tablets and space those out about 8 hours from when I take levothyroxine (synthroid) because it can affect absorption. I think it is recommended to space it out at least 4 hours from taking synthroid, I also take liothyronine (cytomel) about 4 hours after synthyroid, so I try to space the iron 4 hours from any thyroid meds. Are you anemic? Read More
I currently take Levothyroxine 88mcg tabs and Liothyronine Sod 5 mcg tabs (The Liothyronine was added when I was very low) in the morning. My current "T" tests are TSH 0.36 (normal range .34-4.82), T4Free 1.43 (normal range 0.8-1.80), and T3Total 94 (normal range 87-167) I have not worked for over a year now, weight gain in the passed 2 years 25 pounds (never ever had weight problems), exhausted (want to sleep all the time) do not sleep well at all.

 Tissue Level Hypothyroidism Explained
So what can cause "normal" thyroid lab tests but all the symptoms of hypothyroidism? This condition is known as tissue level hypothyroidism (2). Tissue level hypothyroidism may explain why there is a widespread dissatisfaction with standard thyroid treatment and standard thyroid replacement therapy with Levothyroxine or Synthroid . It turns out that there are many patients currently being treated with thyroid hormone and yet they still have all of the symptoms of hypothyroidism, including chronic pain, hair loss, weight gain and weight loss resistance. So what is tissue level hypothyroidism and how does it cause these symptoms? Tissue level hypothyroidism is the idea that you as the patient might have "normal" blood levels of thyroid hormone but due to a number of factors (including inflammation, weight gain, medications, chronic illness, etc.), that thyroid hormone can't get into the cells to do its job. So it remains outside of the cell in the bloodstream making it look like your thyroid function is fine but in reality that thyroid hormone is almost inactive. This is also known as thyroid resistance and it is probably one of the most commonly missed thyroid conditions due to how thyroid diseases are diagnosed. Standard laboratory tests can only measure what is happening in the bloodstream.

Synthroid (Levothyroxine) is a medication commonly prescribed for the treatment of hypothyroidism, and is also a popular intervention for goiters, nodular thyroid disease, and thyroid cancer. Administration of synthroid reverses neurophysiological irregularities associated with insufficient thyroxine (T4) and reduces concentrations of TSH (thyroid-stimulating hormone). Within several months of synthroid administration, many individuals report improvements in mood, energy, and overall well-being. Although synthroid is a synthetically-engineered form of thyroxine called “levothyroxine,” and isn’t bioidentical to endogenously secreted thyroxine (via properly functioning thyroid glands), it is similar enough to improve hypothyroidism biomarkers and symptoms. Assuming the dosage of synthroid is properly calibrated for the specific user, severe side effects and/or adverse reactions are unlikely. Most people are able to tolerate synthroid over a long-term (many years) without complaints of unwanted side effects. Despite the favorable tolerability of synthroid for most users, a subset of users report significant unwanted synthroid side effects, one of which is often weight gain. It is unclear as to how synthroid may cause weight gain as most literature suggests that it is “weight neutral” or unlikely to affect body weight.

Synthroid (Levothyroxine) & Weight Loss: A Common Experience
Synthroid (Levothyroxine) is among the most popular pharmaceutical medications in the United States; over 120 million prescriptions were filled for the drug within the past year. It is a synthetically engineered form of thyroxine (T4), an endogenous thyroid hormone produced by follicular cells within the thyroid gland. Among individuals diagnosed with hypothyroidism, the body is unable to produce adequate T4 (thyroxine) via the thyroid gland, which has deleterious effects upon DNA transcription, protein synthesis, and a multitude of neurophysiological processes. As a result, individuals with hypothyroidism often exhibit symptoms such as: cognitive deficits, depression, dry skin, fatigue, malaise, and weight gain. Regular administration of synthroid (levothyroxine) is thought to reverse the aforementioned symptoms of hypothyroidism and improve functionality of the user. After several months of properly-dosed synthroid, users often report:

Can Levothyroxine make you gain weight? Hidden •
8 years ago • 13 Replies
I'm on 125mg of Levothyroxine, and have been for about 9 years, prior to this I suffered extreme tiredness and disproportionate weight gain. For a while now I've suspected that taking thyroxine has made absolutely no difference to how I feel, I am due my yearly check on Thursday, so as an experiment I haven't taken my Levothyroxine for 2 weeks. I feel absolutely no different, with the exception that I've actually lost about 5lbs, something that, even with effort, would take at least 6 weeks for me to do. So can Levo actually make you gain weight? And if it doesn't make me feel any better is there any point to taking it? Read more about...

Hyperthyroidism is usually associated with weight loss, some people experience an increase in their appetite when they suffer from this condition. Since the body uses energy too quickly, they become hungry faster. This can lead to the excessive intake of food and, in turn, cause weight gain. Treatment Options To Target Weight Gain Caused By Thyroid Disorders
There are many different treatment options available to assist with reducing the effects that Thyroid disorders have on a particular individual’s weight. The first step to determining the best treatment option is to identify the cause. If the Thyroid is, indeed, responsible for the weight gain and the difficult time the person has had in losing weight, then specific blood tests can help a physician determine how much Thyroid Stimulating Hormones, as well as T3 and T4 hormones, are present in the patient’s body. If these hormones are found to be at levels higher than what is considered normal, the patient is diagnosed with Hyperthyroidism. If the levels of these hormones seem to be insufficient, then the patient is diagnosed with Hypothyroidism. Most patients with Hypothyroidism are started out with a dosage of Levothyroxine, a synthetic version of T4 hormones naturally secreted by the Thyroid. Most patients are provided with this medication throughout their lifetime in order to help their bodies with the normal regulation of metabolism.

 In order to treat hypothyroidism and normalize hormone levels doctor prescribes levothyroxine. Proper management of this thyroid disorder and bringing hormone levels up to the normal ratio can help alleviate puffiness in your face. Maintain weight in a healthy range
People with hypothyroidism tend to gain weight. Throughout this post, we have elaborated how hypothyroidism causes weight gain. Thyroid hormones slow down metabolism, decrease thermogenesis, and it also contributes to water retention. Due to all these reasons, it is absolutely necessary to slim down or maintain weight in a healthy range in order to tackle facial swelling. Weight loss can decrease swelling in your face and make it less puffy. Bear in mind that weight loss requires lifestyle adjustments i.e., you shouldn't go for quick fixes and unhealthy solutions. The best way to slim down is to adjust your diet, exercise regularly, and move more. Lower salt intake
We all know that salt intake is tied to water retention, but have you ever wondered why that happens?

Assuming the dosage of synthroid is properly calibrated for the specific user, severe side effects and/or adverse reactions are unlikely. Most people are able to tolerate synthroid over a long-term (many years) without complaints of unwanted side effects. Despite the favorable tolerability of synthroid for most users, a subset of users report significant unwanted synthroid side effects, one of which is often weight gain. It is unclear as to how synthroid may cause weight gain as most literature suggests that it is “weight neutral” or unlikely to affect body weight. However, there is some evidence to suggest that older adults (ages 45 and up) may gain weight as a result of synthroid treatment. Synthroid (Levothyroxine) and Weight Gain
Firstly, it is important note that most medical literature suggests that synthroid does NOT cause significant weight gain. However, assuming you haven’t made any profound changes in eating habits, activity/exercise level, etc. while taking synthroid, yet you’ve packed on a noticeable amount of poundage – it’s probably safe to assume that it was triggered by the drug. Just because the majority of synthroid users are unlikely to gain weight, does not mean that synthroid-induced weight gain should be dismissed as a medical impossibility.

Synthroid should never be used to help you lose weight. Normal doses of Synthroid, which will keep your levothyroxine levels in your body within the normal range, will not cause you to lose any weight. Weight loss only occurs if you take excessively high doses of Synthroid, but these doses can cause serious side effects because of too much levothyroxine in the body. These side effects are particularly likely to occur if you are taking weight loss medications that contain sympathomimetic amines, which are commonly found in appetite-suppressants. Show More

I take oral iron tablets and space those out about 8 hours from when I take levothyroxine (synthroid) because it can affect absorption. I think it is recommended to space it out at least 4 hours from taking synthroid, I also take liothyronine (cytomel) about 4 hours after synthyroid, so I try to space the iron 4 hours from any thyroid meds.

Though these two conditions are vastly different, they’re both usually caused by an autoimmune disease, which causes antibodies to attack the thyroid and make it produce more or less thyroid hormone than the body needs. A host of issues can come along with both of these diagnoses, but many women worry about how their abnormal thyroid production affects their weight. Hyperthyroidism can cause unintentional weight loss, anxiety, and heart palpitations, but it can also increase the appetite, causing people to gain some weight. Hypothyroidism can cause weight gain more directly. It can also cause fatigue, heavier or irregular periods, a slowed heart rate, and chilliness. Luckily, for the one in eight women who will develop a thyroid disorder, according to the American Thyroid Association, hormones are here to help. Tan says that when a blood test reveals abnormal levels, and she diagnoses thyroid dysfunction, she turns to T4 supplements.

 Excessively high doses can occur due to levothyroxine’s narrow therapeutic window. This means there is a small difference between having too little and too much levothyroxine. However, when dosed correctly, the following side effects are less likely to occur ( 10 ):
Weight loss
Tremor
Headache
Nausea
Vomiting
Diarrhea
Stomach cramps
Nervousness
Irritability
Insomnia
Excessive sweating
Increased appetite
Fever
Changes in menstrual cycle
Sensitivity to heat
Temporary hair loss, particularly in children during the first month of therapy. Some of the more concerning levothyroxine side effects include ( 10 ):
Seizures
Chest pain
Irregular heart beat
Swelling of the ankles
Allergic reaction to “fillers” found in levothyroxine tablets can lead to swelling of the face, tongue or throat. Summary: If using too high a dose, levothyroxine can cause numerous side effects. In some cases, levothyroxine can result in serious cardiac, allergy and neurological symptoms. Levothyroxine Precautions
Levothyroxine should be used carefully or not at all in some circumstances. It should not be used as a fat loss aid by people with normal thyroid function. This can cause serious side effects ( 6 ).

About Joe Leech, Dietitian (MSc Nutrition & Dietetics)
 Hypothyroidism refers to an underactive thyroid. It can result from insufficient thyroid hormone production or because thyroid hormones are inactivated before they have time to work ( 1 ). Left untreated it can cause many health issues including fatigue, hair loss, poor memory and weight gain. Summary: In hypothyroidism, the level of active thyroid hormones is lower than what is needed to maintain good health. What is Levothyroxine Sodium? Levothyroxine sodium is an oral medication used to treat — not cure — hypothyroidism ( 2 ). Typically just referred to as Levothyroxine, it’s a synthetic drug that is biologically identical to T4, a prohormone produced by the thyroid ( 2, 3 ). Some of the trade names for levothyroxine sodium include ( 4 ):
Levothroid ®
Levo-T ®
Levoxyl ®
Synthroid ®
Tirosint ®
Unithroid ®

 But a 2017 study examined 1,100 participants with normal thyroid function and found no link between changes in TSH and body mass index (BMI) after a follow-up period of 10 years. 4  However, this study did find that patients with lower levels of free T4 tended to have higher BMIs. The variance in study results further illustrates how intricate the relationship between thyroid hormones and weight really is. The bottom line is that further research is needed. Hypothyroidism and Weight
As discussed above, the simplistic explanation is that having an underactive thyroid often causes people to gain weight because their bodies stop using calories efficiently. A lot of this weight is excess water and salt. Typically, the more severe the hypothyroidism, the greater the weight gain, but usually it's between five and 10 pounds. 5
Somewhere between 10% and 60% of obese adults also have autoimmune hypothyroidism. 2  Some studies have concluded that even mild hypothyroidism can lead to weight changes and may be a risk factor for weight gain and changes in BMI. Verywell / Emily Roberts
Weight Loss With Treatment
There aren't many scientific studies regarding how much weight is gained or lost once hypothyroid people are treated with the synthetic thyroid hormone levothyroxine, but the limited evidence that is available indicates that not everyone loses weight with treatment and in the ones who do, it's limited.

Thyroid Patients: Are You Overmedicated?
What is overmedication?
Signs and symptoms of overmedication
How do you become overmedicated?
What is the treatment for overmedication?
 This may be supported by blood tests that show your thyroid stimulating hormone (TSH) level is suppressed, or in the low end of the reference range, i.e., below 0.5. Your free thyroxine (Free T4) and free triiodothyronine (free T3) may also be elevated, or on the high end of the reference range. Overmedication typically causes symptoms — usually symptoms of hyperthyroidism — although when overmedicated, you may have symptoms like fatigue or weight gain that are more commonly associated with hypothyroidism. Signs and symptoms of overmedication
Some of the most common signs and symptoms of overmedication include the following: An elevated pulse rate
Elevated blood pressure
Heart palpitations or rhythm changes
Anxiety, nervousness, panic attacks
Tremors in your hands
Feeling angry or irritable
Racing mind, difficulty concentrating
Fatigue
Sleep problems, insomnia
Excessive sweating
Feeling overheated; feeling hot when others feel cold; heat intolerance
Diarrhea or loose stools
Weight loss despite no change to exercise or diet, or less commonly, weight gain
An increased appetite and hunger, or loss of appetite
A stable weight or weight loss, despite increased food intake
Craving sugar and carbohydrates and/or eating more sugary foods
The brand-name levothyroxine drug Synthroid also lists as its "side effects" - essentially, the effect of taking too much of the medication - the following symptoms: Chest pain or shortness of breath
Muscle weakness
Vomiting
Fever
Impaired fertility
Decreased bone density
Changes in menstrual periods
Leg cramps
How do you become overmedicated? If you are taking thyroid hormone replacement medication prescribed by your doctor, how can you become overmedicated? There are several ways that this can happen.

 Consider that some of the weight loss may stem from other side effects, especially if they are severe.

Furthermore, the exact causes of synthroid-induced weight loss may be subject to interindividual variability. One individual may lose weight while taking synthroid primarily from BMR increases and diarrhea, while another may lose weight due to the fact that synthroid increased his/her energy enough to maintain a daily fitness routine.

A Word From Verywell
 A lot of this weight is excess water and salt. Typically, the more severe the hypothyroidism, the greater the weight gain, but usually it's between five and 10 pounds. 5
Somewhere between 10% and 60% of obese adults also have autoimmune hypothyroidism. 2  Some studies have concluded that even mild hypothyroidism can lead to weight changes and may be a risk factor for weight gain and changes in BMI. Verywell / Emily Roberts
Weight Loss With Treatment
There aren't many scientific studies regarding how much weight is gained or lost once hypothyroid people are treated with the synthetic thyroid hormone levothyroxine, but the limited evidence that is available indicates that not everyone loses weight with treatment and in the ones who do, it's limited. Once your hormone levels are within the normal range, you may lose a small amount of weight that mainly consists of the extra water and salt your body has built up. However, weight gain has multiple factors and yours is more than likely not all due to your thyroid's slowdown. One way to tell is if treatment has helped all of your other thyroid symptoms but not your weight. This indicates that your thyroid very likely isn't the only factor behind your gain. The More Medication Myth
You may have heard that thyroid hormones can be used to lose weight, even in people without thyroid disease.

If you just started l evothyroxine and you are wondering about side effects, I know what you are worried about: Is levothyroxine actually working for me? Why do I still feel bad if I'm on thyroid medication? How long will it take for me to start feeling BETTER? Are my new symptoms caused by levothyroxine? Why am I still gaining weight on thyroid medication? Are these symptoms normal? If you fall into any of these categories don't worry, because I'm going to go over each one of them.

 clearer thinking, increased energy, mood improvements, and perhaps most noticeably – weight loss. Weight loss is often among the most discussed synthroid side effects due to the fact that nearly everyone wants to look good and maintain a healthy physique. Additionally, many individuals had gained a significant amount of weight prior to using synthroid (as a result of hypothyroidism), a condition which slows metabolism. When metabolic processes are corrected as a result of synthroid, users end up losing weight and the weight loss comes as a pleasant surprise. Synthroid (Levothyroxine) and Weight Loss: A Common Experience
If you’ve lived with hypothyroidism, there’s a chance that you may have gained some weight as a result of the condition. The chief purpose of thyroid hormone is to regulate the body’s metabolism, and when an individual is struggling with a thyroid deficiency, basal metabolic rate (BMR) plummets. Individuals with hypothyroidism may: cut calories, eat a healthy diet, exercise plenty – yet still end up gaining weight due to their slower basal metabolic rate; fewer calories are being burned at rest.

These next steps are designed to help you determine if your body is turning T4 into T3 or if your body is turning your levothyroxine right into Reverse T3. Some of these can be performed at home and others will require a Doctor. It's also worth pointing out that at the end of the day you will need to find a Doctor that is willing to work with you because if you are not getting enough thyroid hormone then you will either need MORE medication or a NEW medication to feel better.

 Synthroid (Levothyroxine) Information
Synthroid (levothyroxine), also known as T4, is a thyroid replacement medication for the treatment of hypothyroidism. T4 is converted in the body to more biologically active, T3. For most individuals, using levothyroxine (T4) sufficient in to treat hypothyroidism but a small percentage of individuals don't efficiently convert T4 to T3. For these individuals, mixed T4/T3 products may be preferred. Levothyroxine is generally well tolerated and side effects are often attributable to the wrong dosage, which can manifest as symptoms of either hypothyroidism or hyperthyroidism. If the dose of levothyroxine is too low, you may experience such symptoms as: Fatigue
Lethargy
Chills
Dry skin
Poor memory
Weight gain
If the dose of levothyroxine is too high, you may experience symptoms of hyperthyroidism, which include: Irritability
Sweating
Palpitations
Tremors
Diarrhea
Weight loss
Levothyroxine is known as a narrow therapeutic index drug, meaning there is a small window of effectiveness in regard to dose. It is important to stay on the same generic manufacturer of levothyroxine to reduce the variability between products. If your pharmacy is switching manufacturers of levothyroxine, be sure to speak with them about your concerns.

How much weight will you gain from synthroid (levothyroxine)?
Does everyone gain weight from taking synthroid (levothyroxine)?
Have you experienced weight gain from synthroid (levothyroxine)?
 Synthetic reaction: The fact that synthroid is a synthetic, rather than bioidentical hormone is problematic for many users. The chemical structure of synthroid differs from endogenously produced thyroxine (T4), and as a result, it may provoke abnormal and unpredictable neurophysiological reactions in users. Weight gain may be one of many possible implications associated with using a synthetically-manufactured hormone, as opposed to one that is endogenously secreted (or even bioidentical). Variables that may influence weight gain from Synthroid (Levothyroxine)
Whenever contemplating the weight you’ve gained from synthroid, it may be helpful to consider influential variables. Examples of such variables to consider that may affect weight gain include: synthroid dosage, duration of administration, other medications or drugs, and your lifestyle. Some users may find that they were gaining weight from an improper synthroid dosage, while others may realize that weight gain could be caused by other pharmaceutical medications. Synthroid dosage
The dosage of synthroid that you’re taking may affect whether you’re likely to gain weight. Individuals taking extremely high dosages are more likely to lose weight than gain weight.

The chemical structure of synthroid differs from endogenously produced thyroxine (T4), and as a result, it may provoke abnormal and unpredictable neurophysiological reactions in users. Weight gain may be one of many possible implications associated with using a synthetically-manufactured hormone, as opposed to one that is endogenously secreted (or even bioidentical). Variables that may influence weight gain from Synthroid (Levothyroxine)
Whenever contemplating the weight you’ve gained from synthroid, it may be helpful to consider influential variables. Examples of such variables to consider that may affect weight gain include: synthroid dosage, duration of administration, other medications or drugs, and your lifestyle. Some users may find that they were gaining weight from an improper synthroid dosage, while others may realize that weight gain could be caused by other pharmaceutical medications. Synthroid dosage
The dosage of synthroid that you’re taking may affect whether you’re likely to gain weight. Individuals taking extremely high dosages are more likely to lose weight than gain weight.

 On September 2015, Sports Illustrated mentioned that anti-doping agencies in the United States and the United Kingdom lobbied for thyroid medications to be added to the list of banned substances by the World Anti-Doping Association. Athletes who have thyroid issues can use levothyroxine to combat normal feelings of fatigue. Doping agencies in the U.S. and United Kingdom felt that healthy athletes might misuse thyroid hormone replacement medications to improve their stamina. Hypothyroid and other thyroid complications often cause a person’s metabolism to slow down. When a person takes medication, they might lose weight as their metabolism normalizes. As such, some healthy people may use levothyroxine for weight loss or obesity despite warnings against this from the University of Michigan. MedlinePlus warns that people who take levothyroxine for weight loss despite having normal health subject themselves to toxic effects from this medication. The medication may not actually help a person lose weight. Recognize Signs of an Overdose
Even when not overdosing, people may experience chest pain or a faster heartbeat that also requires quick medical attention. Levothyroxine overdose symptoms usually consist of the following:
