Patients with hyperthyroidism have to maintain the medication for 1-1.5 years after the indicators are normalized, and the total treatment course is between 1.5 and 2 years. The decision to stop the medication depends on whether the symptoms of hyperthyroidism are relieved, whether the enlarged thyroid gland is significantly reduced, and whether the thyroid stimulating antibodies turn negative. Anti-thyroid medication can have an effect on white blood cells and liver function, so regular blood tests and liver function should be performed while taking the medication, along with liver-protecting and whitening medication if necessary. Some patients with hyperthyroidism may have relapse after recovery, and the relapse rate is very high. Therefore, after recovery, patients with hyperthyroidism should avoid emotional excitement, exertion and iodine-rich foods, and have their thyroid function checked at least once every 0.5 to 1 year. If symptoms of hyperthyroidism appear, thyroid function tests should be performed promptly and at any time to facilitate early detection and treatment.
