1, oral anti-thyroid drugs can inhibit thyroid hormone synthesis, usually with sympathetic nerve inhibitors and psychostimulants to help control palpitations, hand tremors, anxiety and other symptoms. However, it needs to be taken for a long period of time, usually about one and a half to two years before the dosage can be gradually reduced until it is discontinued. However, about one-third to half of patients will relapse after stopping the medication, especially those with significant goiter or those who consume a diet high in iodine (e.g., frequent consumption of seaweed and iodized salt). In addition, a small number of patients may experience adverse drug reactions such as itchy skin, rash or granulocytopenia, and abnormal liver function within the first two to three months of taking the drug. If these phenomena occur, it is advisable to seek timely medical attention to adjust the treatment plan. 2.Radioactive iodine treatment The principle is that radioactive iodine will gather in the thyroid gland to destroy some tissues and reduce the function of thyroid hormone production. Usually patients only need to take it once, and if the effect is not good, they can take it again after six months or a year. The effect is less stable, and the size of the thyroid gland will gradually decrease after treatment. Some patients may even suffer from hypothyroidism due to excessive destruction of the thyroid gland and need to take thyroid hormone for life. This treatment is not recommended for pregnant women and women who intend to become pregnant in the near future (fetal teratogenicity), or for patients with combined eye disease (enlarged protruding eyes). It is not recommended under the age of 18.
