Hypothyroidism is generally not curable and should be treated with lifelong replacement therapy. The goal of treatment is to restore serum TSH values and thyroid hormone levels to the normal range so that clinical signs and symptoms of hypothyroidism disappear, and the dose of treatment depends mainly on the patient’s disease duration, age, weight and individual differences. Thyroid function should be closely monitored during the treatment process and medication should be adjusted in a timely manner. Hypothyroidism treatment medication is relatively single, i.e. thyroid hormone supplementation, which is relatively simple to take once a day. Treatment of hypothyroidism drugs have relatively few side effects, so patients should treat the disease correctly, take medication and monitor it on time, and adjust it in a timely manner to restore normal indicators and improve uncomfortable symptoms as soon as possible. Each person’s situation is different and the severity of symptoms varies, so patients should go to a regular hospital, listen to the clinician’s advice and treat the symptoms.
