Hyperthyroidism is referred to as hyperthyroidism, and the common symptoms of hyperthyroidism mainly include agitation, irritability and insomnia, palpitation, fatigue, fear of heat, excessive sweating, emaciation, hyper appetite, increased stool frequency or diarrhea, and scanty menstruation in women. There is individual variability in the clinical symptoms of patients with hyperthyroidism. Hyperthyroidism is a thyrotoxicosis caused by excessive production of thyroid hormones by the thyroid gland itself. Currently, there is no etiologic treatment for hyperthyroidism, and three treatments are commonly used: antithyroid medications (e.g., methimazole, propylthiouracil), radioactive iodine, and surgical treatment. If symptoms related to hyperthyroidism appear, you should seek medical treatment promptly to avoid delaying your condition.
