What causes the early symptoms of hyperthyroidism?

The early symptoms of hyperthyroidism are mainly caused by autoimmune disorders, genetic factors, environmental factors, etc. 1. Autoimmune disorders The immune system of the body mistakenly regards thyroid tissue as a foreign body to attack, producing antibodies against thyroid, such as thyrotropin receptor antibodies, etc. These antibodies continue to stimulate the thyroid gland, causing it to over-secrete thyroid hormones, thus causing hyperthyroidism. 2. Genetic factors If there are hyperthyroidism patients in the family, the risk of hyperthyroidism in their relatives may increase. Genetic susceptibility may cause individuals to be more sensitive to hyperthyroidism related pathogenic factors. Environmental factors should not be ignored. For example, long-term mental stress, violent mood swings, overwork, etc. may affect the normal regulation of the neuroendocrine system and promote abnormal thyroid hormone secretion. In addition, infection and other external stimuli may also induce hyperthyroidism. 3. Environmental factors iodine is an important raw material for the synthesis of thyroid hormones. Too much or too little iodine may affect thyroid function and increase the possibility of hyperthyroidism. In short, the appearance of early symptoms of hyperthyroidism is the result of multiple factors interacting. Understanding these factors is of great significance for the prevention, diagnosis and treatment of hyperthyroidism. In daily life, attention should be paid to maintaining good living habits and mentality, reasonable intake of iodine, regular physical examination, in order to early detection and treatment of thyroid diseases such as hyperthyroidism.
