Hypothyroidism requires medication, and patients may need to take medication for life. Hypothyroidism is a systemic disease caused by insufficient thyroid hormones. The treatment of hypothyroidism is mainly through medication, such as levothyroxine. If hypothyroidism is not controlled by medication, and the condition is allowed to develop, hypothyroidism heart disease, hypothyroidism anemia and other diseases may occur, and coma may occur in severe cases. However, patients with hypothyroidism should not take medication privately, and need to take medication under the guidance of a doctor. And patients with hypothyroidism need to strictly follow the doctor’s instructions during the taking of medication, not to arbitrarily increase or decrease the amount of medication. And the patient should go to the hospital regularly for follow-up, so that the doctor can adjust the dosage of the drug. Patients with hypothyroidism can return to normal life with reasonable hormone replacement therapy.
