Clinically, it can be found that many patients with hyperthyroidism have some precipitating factors before the onset of the disease, such as mental irritation, infection and trauma. Some people found that 60% of hyperthyroidism patients have mental stimulation factors, such as conflicts and arguments with others, or overwork and stress, among which long time or strong mental stimulation is more increased, which may be related to mental factors such as panic and stress. Infection and trauma are also important triggering factors for hyperthyroidism. Many patients with hyperthyroidism have a history of acute infection or trauma before the onset of the disease. In addition, iodine can also trigger hyperthyroidism. Some people believe that these factors can trigger hyperthyroidism because the thyroid gland of these patients is defective and when these factors are present, hyperthyroidism is triggered. It is also believed that these triggering factors are various factors in the pathology of hyperthyroidism. Therefore, in order to reduce the chance of developing hyperthyroidism, these triggering factors should be avoided as much as possible.
