There are three main treatments for hyperthyroidism, including internal antithyroid medication (e.g., methimazole, propylthiouracil, etc.), 131 iodine therapy, and surgical treatment. The treatment is relatively mild and the dosage of medication can be adjusted at any time during the treatment process. However, the treatment time is long, usually 2-3 years. During the treatment period, regular check-ups of nail function, blood routine and liver function are needed, because antithyroid drugs can cause damage to liver function and hematopoietic system; in addition, the drugs can cause allergic reactions, and it is easy to cause relapse of hyperthyroidism by reducing the dose or stopping the drugs during treatment. 2.Surgical treatment can quickly relieve hyperthyroidism symptoms, especially for patients with obvious enlargement of the thyroid gland and nodules. However, surgery can cause more damage, such as damage to the laryngeal nerve and parathyroid glands in some patients, and some patients have relapse of hyperthyroidism or hypothyroidism. 3. 131 iodine treatment is a simple treatment method and can relieve hyperthyroidism symptoms faster. The main disadvantage is that a small number of patients develop hypothyroidism, but hypothyroidism can be treated with simple daily thyroid hormone replacement therapy. For patients with abnormal liver function or reduced white blood cells due to anti-thyroid medication, allergies, and for patients who have had poor results with anti-thyroid medication, 131 iodine therapy is an option.
