Other names: Thyroid, underactive


Hypothyroidism is a condition where the thyroid gland does not produce enough hormones. It can lead to various health problems like obesity, joint pain, infertility, and heart disease. However, with proper diagnosis through thyroid function tests and treatment with synthetic thyroid hormone, the condition can be effectively managed.


Symptoms of hypothyroidism include fatigue, sensitivity to cold, constipation, dry skin, weight gain, muscle weakness, depression, and slowed heart rate. If left untreated, it can progress to more severe symptoms like an enlarged thyroid (goiter) and myxedema which can be life-threatening.


Causes of hypothyroidism include autoimmune disease (Hashimoto's thyroiditis), treatment for hyperthyroidism, thyroid surgery, radiation therapy, and certain medications. Less common causes include congenital disease, pituitary disorder, pregnancy-related factors, and iodine deficiency.


Risk factors for hypothyroidism include being a woman over 60 years old, having an autoimmune disease, undergoing certain treatments or surgeries affecting the thyroid gland, recent pregnancy, or a family history of thyroid disorders.


Untreated hypothyroidism can lead to complications such as goiter, heart problems, mental health issues like depression, peripheral neuropathy, myxedema coma, infertility, and birth defects in infants born to mothers with untreated thyroid disease.


Diagnosis is based on symptoms and blood tests measuring TSH and thyroxine levels. Treatment involves synthetic thyroid hormone levothyroxine to restore hormone levels. Proper dosage adjustment over time is crucial for effective management.


Levothyroxine is the standard treatment for hypothyroidism. It should be taken consistently to avoid symptoms returning. Proper absorption of levothyroxine may be affected by certain medications or foods. Alternative natural extracts are available but should be used with caution due to lack of regulation.
