People with hypothyroidism often have no or only mild symptoms. Numerous symptoms and signs are associated with hypothyroidism and can be related to the underlying cause, or a direct effect of having not enough thyroid hormones. Hashimoto's thyroiditis may present with the mass effect of a goiter (enlarged thyroid gland). In middle-aged women, the symptoms may be mistaken for those of menopause. Symptoms and signs of hypothyroidism Symptoms Signs Fatigue Dry, coarse skin Feeling cold Cool extremities Poor memory and concentration Myxedema (mucopolysaccharide deposits in the skin) Constipation, dyspepsia Hair loss Weight gain with poor appetite Slow pulse rate Shortness of breath Swelling of the limbs Hoarse voice Delayed relaxation of tendon reflexes In females, heavy menstrual periods (and later light periods) Carpal tunnel syndrome Abnormal sensation Pleural effusion, ascites, pericardial effusion Poor hearing Delayed relaxation after testing the ankle jerk reflex is a characteristic sign of hypothyroidism and is associated with the severity of the hormone deficit. Myxedema coma Myxedema coma is a rare but life-threatening state of extreme hypothyroidism. It may occur in those with established hypothyroidism when they develop an acute illness. Myxedema coma can be the first presentation of hypothyroidism. People with myxedema coma typically have a low body temperature without shivering, confusion, a slow heart rate and reduced breathing effort. There may be physical signs suggestive of hypothyroidism, such as skin changes or enlargement of the tongue. Pregnancy Even mild or subclinical hypothyroidism leads to possible infertility and an increased risk of miscarriage. Hypothyroidism in early pregnancy, even with limited or no symptoms, may increase the risk of pre-eclampsia, offspring with lower intelligence, and the risk of infant death around the time of birth. Women are affected by hypothyroidism in 0.3–0.5% of pregnancies. Subclinical hypothyroidism during pregnancy is associated with gestational diabetes and the birth of the baby before 37 weeks of pregnancy. Children Newborn children with hypothyroidism may have normal birth weight and height (although the head may be larger than expected and the posterior fontanelle may be open). Some may have drowsiness, decreased muscle tone, a hoarse-sounding cry, feeding difficulties, constipation, an enlarged tongue, umbilical hernia, dry skin, a decreased body temperature, and jaundice. A goiter is rare, although it may develop later in children who have a thyroid gland that does not produce functioning thyroid hormone. A goiter may also develop in children growing up in areas with iodine deficiency. Normal growth and development may be delayed, and not treating infants may lead to an intellectual impairment (IQ 6–15 points lower in severe cases). Other problems include the following: difficulty with large scale and fine motor skills and coordination, reduced muscle tone, squinting, decreased attention span, and delayed speaking. Tooth eruption may be delayed. In older children and adolescents, the symptoms of hypothyroidism may include fatigue, cold intolerance, sleepiness, muscle weakness, constipation, a delay in growth, overweight for height, pallor, coarse and thick skin, increased body hair, irregular menstrual cycles in girls, and delayed puberty. Signs may include delayed relaxation of the ankle reflex and a slow heartbeat. A goiter may be present with a completely enlarged thyroid gland; sometimes only part of the thyroid is enlarged and it can be knobby. Related disorders Thyroid hormone abnormalities are common in major psychiatric disorders including bipolar disorder; clinical research has shown there is a high rate of thyroid dysfunction in mood disorders and schizophrenia-spectrum disorders, concluding that there is a case for screening for the latter among people with thyroid illness.
