Hyperthyroidism is a disease caused by hyperthyroidism, which can be divided into three categories: primary, secondary and high-functioning adenoma. Primary hyperthyroidism is the most common and is thought to be related to autoimmune imbalance. It accounts for 85% to 90% of all hyperthyroid patients and is more common in women. Secondary hyperthyroidism and high-functioning adenoma are both relatively rare. Secondary hyperthyroidism refers to the appearance of symptoms of hyperthyroidism in patients who originally suffered from nodular goiter, usually without protruding eyes, but prone to heart muscle damage. If one or more autonomic hyperfunctioning nodules grow in the thyroid gland, it is called hyperfunctioning adenoma thyroid, and this type of hyperthyroidism requires nuclear tests to confirm the diagnosis. Surgery, antithyroid drugs and radioactive iodine 131 are the main treatments for hyperthyroidism. Most patients with primary hyperthyroidism can be controlled by medication. Commonly used anti-thyroid drugs include propylthiouracil (PTU) and Sage; patients with tachycardia can take propranolol (TCM) to control their heart rate; and some immunomodulatory drugs or Chinese medicines can help balance the immune function of the whole body. For patients with secondary hyperthyroidism or high-functioning adenoma; primary hyperthyroidism of moderate degree or above; large gland with compression of trachea or retrosternal goiter; patients with relapse after antithyroid medication or iodine 131 treatment can consider surgery, and for patients in early or mid pregnancy with the above indications, surgery can also be considered. The long-term cure rate of surgery is over 95% and the mortality rate is less than 1%.
