The survival period of hyperthyroidism is related to the treatment and the occurrence of complications, and cannot be generalized. Hyperthyroidism, or hyperthyroidism, is an endocrine disorder caused by excessive secretion of thyroid hormones, resulting in hyper-metabolism and sympathetic excitation. Hyperthyroidism does not affect the life expectancy of patients if they are treated properly. However, if hyperthyroidism is incompletely treated or if complications arise that affect other organs, such as the heart and eyes, or even if hyperthyroid crisis occurs, their clinical death rate can be more than 20%, and severe cases can end their lives in a short period of time. In addition, the treatment period of hyperthyroidism is long and patients are prone to relapse due to poor compliance, and serious conditions may occur if treatment is not timely, which may affect their life expectancy. Therefore, it is recommended that patients with hyperthyroidism should be reviewed regularly at the endocrinology department of the hospital to intervene as soon as abnormalities appear and adhere to treatment. At the same time, they should control the intake of iodine in their diet, take regular rest and rest, and exercise properly.
