Hyperthyroidism

Hyperthyroidism, referred to as hyperthyroidism, refers to thyroid poisoning caused by the thyroid gland itself producing excessive thyroid hormones. The main causes are diffuse toxic goiter (Graves disease), multi-nodular toxic goiter, and high thyroid autonomy. Functional adenoma (Plummer's disease), which is commonly characterized by increased metabolism of thyroid hormones and increased excitability of the sympathetic nervous system, has different clinical manifestations depending on the cause. It is worth noting that the concept of hyperthyroidism is different from thyroidism, which refers to the special metabolic changes and pathophysiological changes of tissue function caused by tissues exposed to excessive thyroid hormones. Roughly speaking, thyrotoxicosis is a result, and hyperthyroidism is just one of the diseases that cause this result. The two are not the same. Most of the patients with hyperthyroidism have a slow onset and also have acute onset. The incidence is about 31 / 100,000, which is more common in women. The ratio of male to female is about 1: 4 to 6.
