Have you experienced weight gain from synthroid (levothyroxine)?
 If you notice that you become increasingly fatigued and/or lethargic throughout treatment, chances are that you’ll gain some weight. Fatigue makes it difficult to remain physically active, engage in regular exercise (to burn calories and keep metabolism high), and also difficult to make healthy decisions regarding foods to eat. Neurotransmission: Regular administration of synthroid may decrease concentrations of dopamine. Precursors such as tyrosine appear to decrease in the brain of rodents regularly administered synthroid. It is plausible to consider that humans who’ve taken synthroid for a long-term may end up with low dopamine (at least in certain regions of the brain). Reductions in dopamine could lead to poorer appetite control, feeling less satiated after eating, etc. – possibly contributing to weight gain. Sleep disturbances: It is understood that a quality night’s sleep is beneficial for maintaining a healthy 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. There’s never a one-size-fits-all response to medications – responses (and especially synthroid side effects) are subject to interindividual variation. While most people may not gain weight from synthroid, you may happen to be the outlier who ends up packing on the poundage; possibly to a significant extent. It may be frustrating to inquire about synthroid as the culprit for your weight gain to a medical professional, especially if you are told “synthroid does not cause weight gain.” Other content on MentalHealthDaily.com

 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. 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

 dietary intake, exercise level, sleep, stress, etc. – only to realize that nothing much has changed. At this point, you may want to talk to your doctor about going without synthroid and/or switching to another medication to see if your weight normalizes. That said, you should keep in mind that temporary fluctuations in body weight may be common over the first few weeks or months of synthroid treatment; these may subside with continued synthroid administration. How Synthroid May Cause Weight Gain (Possibilities)
There are numerous possible ways in which synthroid administration could cause weight gain in a subset of users. Understand that there may be interindividual variation in the causative factors responsible for the weight gain. Some individuals may gain weight as a result of the fact that their appetite increases while taking synthroid, yet another person may realize that synthroid causes bloating and/or changes in gut bacteria that lead to weight gain. Appetite increase: Though some individuals find synthroid beneficial for reducing appetite, others notice a significant increase in appetite during synthroid treatment.

 In other words, regular administration of synthetic thyroxine (levothyroxine) may alter the densities of particular gut bacterium. As a result of changes in gut bacteria associated with synthroid, users may gain weight without any dietary or exercise changes solely resulting from bacteria in the gut. Low energy: Not everyone feels energetic and spry after taking synthroid. Some individuals report feeling lower energy after taking synthroid than prior to treatment. If you notice that you become increasingly fatigued and/or lethargic throughout treatment, chances are that you’ll gain some weight. Fatigue makes it difficult to remain physically active, engage in regular exercise (to burn calories and keep metabolism high), and also difficult to make healthy decisions regarding foods to eat.

I also take levothyroxine (150mg/day). I have learned that it is critical to take it at the same time every day, with respect to meals, because empty v. full stomach affects how it is absorbed. This can throw off your levels. I have read in many, many books and articles that it is just plain harder to lose weight at all when you have a thyroid problem (Thyroid Sourcebook is a good resource). If you have access to a nutritionist or dietitian, maybe through your endo, I have found that they're very helpful.

Appetite increase: Though some individuals find synthroid beneficial for reducing appetite, others notice a significant increase in appetite during synthroid treatment. Any increase in appetite, regardless of whether small or large, will increase the likelihood that you’ll consume more food (and calories throughout the day). The more food that you consume throughout the day, the more likely you’ll be to gain weight. Bloating: A side effect that synthroid users report is stomach bloating characterized by heightened build-up of fluid and/or gas. If you feel bloated while taking synthroid, you’re certainly not alone.

 It is plausible to consider that humans who’ve taken synthroid for a long-term may end up with low dopamine (at least in certain regions of the brain). Reductions in dopamine could lead to poorer appetite control, feeling less satiated after eating, etc. – possibly contributing to weight gain. Sleep disturbances: It is understood that a quality night’s sleep is beneficial for maintaining a healthy body weight. Adequate deep sleep keeps the metabolism within a healthy range and allows the body to produce hormones to prevent weight gain. Lack of sleep increases ghrelin (the hunger hormone) and may disrupt other metabolic processes, ultimately leading to weight gain. Since synthroid administration may cause insomnia and sleep disturbances in some users, its interference with a good night’s sleep may indirectly contribute to weight gain.

 High dosages of synthroid are thought to increase basal metabolic rate (BMR) and the number of calories burned at rest. On the other hand, those taking low dosages of synthroid may end up gaining weight as a result of inadequately treated hypothyroidism. At extremely low dosages, you may not attain enough synthroid to counteract the metabolic slowing that occurs with hypothyroidism. It may take your doctor awhile to find the optimal dosage to get your TSH levels within a normative range. Synthroid dosing is known to have an NTI (narrow therapeutic index). In some cases, even high-dose users may end up gaining some weight – assuming their neurophysiology reacts unusually to the synthroid. A properly calibrated dosage by a medical professional (e.g. endocrinologist) should help reduce likelihood of weight gain (or loss) while taking synthroid. Duration of administration
The duration over which you’ve taken synthroid (levothyroxine) may affect how likely you are to gain weight. It is possible that some users may gain weight over a short-term (e.g. less than 3 months of treatment), while others may notice some weight gain over a

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

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.

 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.

 There’s never a one-size-fits-all response to medications – responses (and especially synthroid side effects) are subject to interindividual variation. While most people may not gain weight from synthroid, you may happen to be the outlier who ends up packing on the poundage; possibly to a significant extent. It may be frustrating to inquire about synthroid as the culprit for your weight gain to a medical professional, especially if you are told “synthroid does not cause weight gain.” Other content on MentalHealthDaily.com

This may lead you assess any recent changes in: dietary intake, exercise level, sleep, stress, etc. – only to realize that nothing much has changed. At this point, you may want to talk to your doctor about going without synthroid and/or switching to another medication to see if your weight normalizes. That said, you should keep in mind that temporary fluctuations in body weight may be common over the first few weeks or months of synthroid treatment; these may subside with continued synthroid administration.

 Some people report such severe bloating, that they appear as if they’re pregnant. It may be necessary to consider that the extra weight retained as a result of bloating may be perceived as minor weight gain. Constipation: In addition to bloating, some individuals note that synthroid induces constipation. If you find it difficult to pass a bowel movement, some of the increased weight that you notice may be a result of your constipation. It may be helpful to intervene with increased dietary fiber, hydration, and/or laxative agents. Keep in mind that constipation is unlikely to cause a significant amount of weight gain, but may contribute slightly to your overall weight increase if you experience it. Food cravings: Although fairly rare, some users report hunger pains and/or substantial food cravings while taking synthroid. You may find yourself craving unhealthy foods such as:

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.

 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. High dosages of synthroid are thought to increase basal metabolic rate (BMR) and the number of calories burned at rest. On the other hand, those taking low dosages of synthroid may end up gaining weight as a result of inadequately treated hypothyroidism. At extremely low dosages, you may not attain enough synthroid to counteract the metabolic slowing that occurs with hypothyroidism. It may take your doctor awhile to find the optimal dosage to get your TSH levels within a normative range. Synthroid dosing is known to have an NTI (narrow therapeutic index).

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.

 Adequate deep sleep keeps the metabolism within a healthy range and allows the body to produce hormones to prevent weight gain. Lack of sleep increases ghrelin (the hunger hormone) and may disrupt other metabolic processes, ultimately leading to weight gain. Since synthroid administration may cause insomnia and sleep disturbances in some users, its interference with a good night’s sleep may indirectly contribute to weight gain. ( Source: http://www.ncbi.nlm.nih.gov/pubmed/18564298). 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.

Hi, all. I was wondering if anyone else has taken levoythyroxine and experienced weight gain as opposed to loss? Several months ago, my endocrinologist had my thyroid levels tested. She said they were *just* under what is considered "normal" and that if it weren't for my prolactinoma, she wouldn't be treating for hypothyroidism at all. ( She thinks the size of the tumor is impacting my thyroid function.) I started Levothyroxine in February. When I went to my endocrinologist in February, I had actually lost 7lbs. When I saw her last week (5 months later), I had somehow gained weight -- about 10lbs worth. I asked her if it could be related to the levo, and she said no -- and then said that it was something that I had caused, even though I really haven't changed anything - if anything, I have actually become more active because I'm working more (retail) instead of sitting in school all day. Now, she wants to test for Type 2 Diabetes and a slew of other things and is contemplating putting me on another medication to "control my weight."

Does everyone gain weight from taking synthroid (levothyroxine)?
Have you experienced weight gain from synthroid (levothyroxine)?
 It may be helpful to intervene with increased dietary fiber, hydration, and/or laxative agents. Keep in mind that constipation is unlikely to cause a significant amount of weight gain, but may contribute slightly to your overall weight increase if you experience it. Food cravings: Although fairly rare, some users report hunger pains and/or substantial food cravings while taking synthroid. You may find yourself craving unhealthy foods such as: candies, cookies, and various sugary treats. Assuming you are unable to resist these cravings, you’re probably going to gain some weight. To minimize your chances of falling victim to food cravings, you may want to avoid purchasing any foods that reinforce these cravings during synthroid treatment. Gut bacteria: Pharmaceutical medications, especially synthetic ones like synthroid, may be altering your gut microbiome.

 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.

 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. Also often present in later stages are slowed speech, goiters, and abnormal menstrual cycles in females. Levothyroxine and weight loss are directly related, meaning that, the higher the dose prescribed or administered, the more significant the weight loss effects. Weight loss is only one of the multitude of possible adverse effects surrounding levothyroxine use. Other such effects include abdominal pain, palpitations, and insomnia. Also common are agitation and mood swings, nausea, and appetite swings.

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)).

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...

Have you lost weight while taking Synthroid (levothyroxine)?
 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:

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:

I was diagnosed with Graves' disease 10 years ago & finally did the radiation 2 years ago. I have been on Levo for 2 years. In the last year gained 30 pounds, 8 pounds in the last 2 months. I asked me endocrinologist today at my appt of it could be the hormones & if I could try new ones, she told me no! She said I was always this because of my thyroid and maybe I'm supposed to be a big girl & my body is just doing its thing!!

My doctor back then did warn me and tell me that a big side effect of not taking Levothyroxine would be weight gain. Ever since I stopped taking Levothyroxine, I have not suffered or noticed any side effects other than the major weight gain. I don't feel tired or sick or anything. I'm always full of energy and up and about. Today I finally mustered up the courage to call an endocrine health center for an appointment. My appointment will be on the 31st of this month. Read More

 I started Levothyroxine in February. When I went to my endocrinologist in February, I had actually lost 7lbs. When I saw her last week (5 months later), I had somehow gained weight -- about 10lbs worth. I asked her if it could be related to the levo, and she said no -- and then said that it was something that I had caused, even though I really haven't changed anything - if anything, I have actually become more active because I'm working more (retail) instead of sitting in school all day. Now, she wants to test for Type 2 Diabetes and a slew of other things and is contemplating putting me on another medication to "control my weight." I really don't want to take a third medication. Has anyone experienced something similar? Also, has anyone who has combined levothyroxine with cabergoline had any side effects related to weight? Thanks,

 Sometimes the issue is conversion. You may be converting the T4 to reverse T3 and this Reverse T3 is docking in the T3 receptor sites and disabling them form being activated by actual T3. Ask your doctor to check a RT3 and if its >10%, decrease the T4 and add T3 . you may want to do a 2 week washout period from the levo ( refrain from taking it altogether) to lower your RT3 and T4

If you're a health care professional and you haven't heard that Synthroid or Levothyroxine will cause weight gain, you're completely out of touch. I was 50 yrs old when diagnosed, had already had three children and had only weighed 107 9 mos. pregnant. Absolutely nothing made me gain weight. I weighed 98 at age 50 and within five mos., I had gained 17 lbs. This is a very common complaint, and nobody seems to be able to explain it or care.

 Consider that some of the weight loss may stem from other side effects, especially if they are severe. Note: Although weight loss from synthroid is thought to primarily stem from increases in BMR, other potential causative factor should not be dismissed. 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.

Does everybody lose weight while taking synthroid (levothyroxine)?
Have you lost weight while taking Synthroid (levothyroxine)?
 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: appetite reduction, cognitive enhancement, increased energy, altered neurotransmission, and side effects (e.g. diarrhea). Appetite reduction: Many synthroid users report that the drug decreases and/or suppresses their appetite. Assuming you feel less hungry than usual while taking synthroid, there’s a good chance that you’ll probably eat less food and end up losing some weight. In a subset of individuals diagnosed with hypothyroidism, an overwhelming appetite is problematic and leads to constant overeating.

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:

About Dr. Westin Childs
 Well, the truth is that Levothyroxine doesn't necessarily increase your metabolism ... at least not in everyone. In this post I'm going to show you exactly why Levothyroxine can cause weight gain and what you can do about it: More...
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. By itself it doesn't do anything for your body except act as a reservoir for T3 and T3 is the active thyroid hormone in your body . T3 is what enters into your cells and turns on the genes that increase your metabolism, help with hair growth and give you energy. In order for T4 thyroid hormone to be active in your body, it MUST be converted to the active hormone T3. The problem is that T4 doesn't always convert to T3: (This image shows what is required to convert T4 into the active free T3 hormone, it also outlines what causes your body to turn T4 into the inactive reverse T3)

 It has nothing to do with conversion of T4 to T3 or not having enough T4 ; medication. Right now, I am running scared because every now and then, the weight will start coming on without a reason. My dosage was raised, and I started gaining faster along with having heart palpitations and hot flashes. Labs showed I had gone hyperthyroid. Weight is now at 132. I am 4'11". RO

Have you lost weight while taking Synthroid (levothyroxine)?
 For this reason, it should be hypothesized that altered concentrations of neurotransmitters (e.g. monoamines) and/or changes in neural activation following synthroid administration – may contribute (directly or indirectly) to weight loss. It is understood that neurochemical changes can affect propensity to lose weight. Placebo effect: It may be necessary to consider that in a subset of synthroid users, the placebo effect contributes to weight loss. Some individuals may expect to lose weight while taking synthroid, and the weight loss becomes a self-fulfilling prophesy. Since the scientific literature reports that synthroid isn’t associated with significant changes in body weight (on average), yet many users still report weight loss – the placebo effect should be considered a potential contributing factor. Side effects: In some cases, users of synthroid may experience weight loss as a result of other side effects. For example, if synthroid is provoking round-the-clock diarrhea, the laxative effect will likely contribute to some degree of weight loss. Additionally, it could be that synthroid causes nausea and/or stomach aches – each of which may interfere with a person’s appetite, resulting in reduced food consumption.

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.

 8. Nope. I think maybe the possibility is a combination of a few things. Sodium is possibly on the high side. Combine that with not drinking enough water and you end up with water retention. Possibility of over-eating. In the amount of time that you gained, its only like an extra 25 or so calories per day since feb. There could also be a little water retention in your muscles from the increased activity. I'd try tracking your calories, consistently for a month or so. Oh and I forgot to ask, How do your clothes fit?

 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.

 It is possible that the reduction of ghrelin as a result of synthroid administration leads users to feel more satiated with fewer food cravings than usual. ( Source: http://www.ncbi.nlm.nih.gov/pubmed/23339003)
Gut bacteria: There is some evidence to suggest that some cases of hypothyroidism may be caused by small-intestine bacterial overgrowth (SIBO) within the gut. It is known that a person’s gut bacteria can be predictive of whether they’re likely to lose or gain weight from eating a certain set of foods. 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.

 Since the scientific literature reports that synthroid isn’t associated with significant changes in body weight (on average), yet many users still report weight loss – the placebo effect should be considered a potential contributing factor. Side effects: In some cases, users of synthroid may experience weight loss as a result of other side effects. For example, if synthroid is provoking round-the-clock diarrhea, the laxative effect will likely contribute to some degree of weight loss. Additionally, it could be that synthroid causes nausea and/or stomach aches – each of which may interfere with a person’s appetite, resulting in reduced food consumption. Consider that some of the weight loss may stem from other side effects, especially if they are severe. Note: Although weight loss from synthroid is thought to primarily stem from increases in BMR, other potential causative factor should not be dismissed. 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.

About Dr. Westin Childs

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.
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.
Step #1: Check your Basal Body Temperature Each Morning
Checking your basal body temperature is a quick and easy way to estimate your basal metabolic rate.

 When taking synthroid, your energy level may skyrocket (compared to what it was) and you may end up going to the gym, moving around more, etc. – all of which can burn calories, enhance your metabolism, and contribute to weight loss. Ghrelin reduction: A hormone responsible for regulating hunger, known as “ghrelin,” is abnormally high among individuals with hypothyroidism. Ongoing administration of levothyroxine (synthroid) appears to significantly reduce ghrelin concentrations. It is possible that the reduction of ghrelin as a result of synthroid administration leads users to feel more satiated with fewer food cravings than usual. ( Source: http://www.ncbi.nlm.nih.gov/pubmed/23339003)
Gut bacteria: There is some evidence to suggest that some cases of hypothyroidism may be caused by small-intestine bacterial overgrowth (SIBO) within the gut. It is known that a person’s gut bacteria can be predictive of whether they’re likely to lose or gain weight from eating a certain set of foods.

Are you on Levothyroxine but still gaining weight? Believe it or not, this is a big problem for a lot of people. But the bigger question is this: How can you be gaining weight on a medication that is supposed to INCREASE your metabolism? Is it even possible?

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.

 Remember also that your T4 is a storage hormone and it may well take several weeks before your body is depleted and you once again feel unwell....also less to convert into the ACTIVE T 3.....

I continued to gain weight when I first started on Levo, it took 18 months and calorie counting to get rid of 6st, I still have 1st to go but I had to be very disciplined with my diet and would often go for weeks and weeks with no weight loss which I'm sure is due to my thyroid. Hidden 8 years ago
Similar experience here - I put on 5 stone in a year when they zapped my thyroid and put me on levo 5 years ago. Glib doctors advised dieting, but dieting didn't make an ounce of difference. Very upsetting. At least my weight reached a plateau and I could start buying clothes again without growing out of them in a few months - even if they did have to be 4 sizes bigger! Now I'm using thyroid S and have lost half a stone this year. Fingers x-ed this slow weight loss is going to continue. If I can reach a lower, plateau a stone or so lower I might try dieting again. The killer is trying to keep weight off, of course. I'm not recommending thyroid S - each one of us has a different reaction to the different meds available, as this site demonstrates in Spades.

 all throughout the day. Assuming you have fewer overall food cravings, you’re likely to consume less unhealthy “junk food” and could end up losing some weight. Energy increase: There’s a stark contrast in the energy level of an individual with an optimally functioning thyroid and someone who’s suffering from hypothyroidism. Most individuals with hypothyroidism slog through the day with considerable fatigue and grogginess, making it challenging and less appealing to stay active and/or exercise. When taking synthroid, your energy level may skyrocket (compared to what it was) and you may end up going to the gym, moving around more, etc. – all of which can burn calories, enhance your metabolism, and contribute to weight loss.

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:

 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). For this reason, it should be hypothesized that altered concentrations of neurotransmitters (e.g. monoamines) and/or changes in neural activation following synthroid administration – may contribute (directly or indirectly) to weight loss. It is understood that neurochemical changes can affect propensity to lose weight. Placebo effect: It may be necessary to consider that in a subset of synthroid users, the placebo effect contributes to weight loss. Some individuals may expect to lose weight while taking synthroid, and the weight loss becomes a self-fulfilling prophesy.

 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.

I ripped 2 pairs of soandex in two days. I used to battle with an eating disorder so this weight gain is eating me alive. Pathetic : ( mayb I'll try without it see what happens! WY

I had quit taking it because I was gaining weight and I mentioned it to him at my last visit on 9/23 and he said not taking it probably caused me to gain but I had been gaining while on it so that's why I quit.

 pregnant. Absolutely nothing made me gain weight. I weighed 98 at age 50 and within five mos., I had gained 17 lbs. This is a very common complaint, and nobody seems to be able to explain it or care. It has nothing to do with conversion of T4 to T3 or not having enough T4 ; medication. Right now, I am running scared because every now and then, the weight will start coming on without a reason. My dosage was raised, and I started gaining faster along with having heart palpitations and hot flashes. Labs showed I had gone hyperthyroid.

 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.

 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.

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)?
 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. 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.

 Upon correction of hypothyroidism-associated cognitive deficits (as a result of synthroid treatment), individuals are able to make better decisions about the foods that they consume and exert more overall self-restraint to avoid unhealthy food choices. Decreased food cravings: In some individuals, hypothyroidism may contribute to food cravings, especially for junk food (e.g. artificial sweeteners, sugars, simple carbs, etc.). With regular administration of synthroid, some individuals may find that food cravings subside. You may feel as if you no longer are constantly craving carbs, cookies, candies, etc. – all throughout the day. Assuming you have fewer overall food cravings, you’re likely to consume less unhealthy “junk food” and could end up losing some weight. Energy increase: There’s a stark contrast in the energy level of an individual with an optimally functioning thyroid and someone who’s suffering from hypothyroidism. Most individuals with hypothyroidism slog through the day with considerable fatigue and grogginess, making it challenging and less appealing to stay active and/or exercise.

About Dr. Westin Childs
 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?

 If you are a TSH and T4 only doctor your patient will remain symptomatic and miserable for years. The doctor should always listen to the patient and believe what they are reporting - and then read up or consult and expert in order to help that patient (if they do not already know a solution). Anyone prescribing the monotherapy of T4 isn't going to get very far - their patients will continued to suffer all the things you read in link 2. JA

I was so Uncomf infelt like I was getting it for weeks- I would cry in pain. Now I get it regularly idk which is worse loose my period or loose my mind by how heavy I have gotten.

If you are a TSH and T4 only doctor your patient will remain symptomatic and miserable for years. The doctor should always listen to the patient and believe what they are reporting - and then read up or consult and expert in order to help that patient (if they do not already know a solution). Anyone prescribing the monotherapy of T4 isn't going to get very far - their patients will continued to suffer all the things you read in link 2. JA

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)). Doses greater than 200 mcg/day (or 2 mg/day) are not usually required. So 125 mcg (1.25 mg) per day is in the normal dose range, but only your blood tests will tell whether it is the correct dose for you. It may take time and re-checking of your labs to get the correct blood levels. As for the weight gain ... if you are not eating any more than you did before you started treatment (possible side effect is increased appetite), then - are you retaining fluid?? That is a possibility, or your dose may need to be adjusted.

I had quit taking it because I was gaining weight and I mentioned it to him at my last visit on 9/23 and he said not taking it probably caused me to gain but I had been gaining while on it so that's why I quit. He said once I started it again I would probably start losing weight. Hasn't happened yet : ( I'm beginning to wonder if I should go to an endocrinologist. Thank you all for your comments and links. I'm going to sit down and start reading very carefully.

To jaroslaw666: Your criticism of the second link doesn't make sense. These are just people recording observations of their symptoms after taking this horrible drug. If you read a lot of them you will be able to see a pattern. If you are a doctor with an analytical mind you will be able to work with that patient and come to a solution.

 appetite reduction, cognitive enhancement, increased energy, altered neurotransmission, and side effects (e.g. diarrhea). Appetite reduction: Many synthroid users report that the drug decreases and/or suppresses their appetite. Assuming you feel less hungry than usual while taking synthroid, there’s a good chance that you’ll probably eat less food and end up losing some weight. In a subset of individuals diagnosed with hypothyroidism, an overwhelming appetite is problematic and leads to constant overeating. Synthroid administration may reduce a large appetite and decrease the urge to eat. Cognitive function: It is understood that those with hypothyroidism often exhibit brain fog, inability to think clearly, and poor cognitive function. As a result, many people with hypothyroidism make impulsive food choices and lack a nutrient-dense diet. Poor nutrition exacerbates existing cognitive deficits and perpetuates future suboptimal dietary choices.

 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.
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".

 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? 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).
