Between heaven and earth, people's liver and spleen are depressed, and there is unknown epidemic gas from the outside to the inside, which leads to poor blood circulation, while in front of the neck, depression occurs, and kidney gas is also lost. After a long time, the temper becomes weak, leading to fatigue. This is a common cause of Hashimoto thyroiditis.

Second, the physical factors:

The etiology of Hashimoto's thyroiditis is closely related to physical fitness. People with body yin deficiency will lose body fluid due to internal heat, or deficiency of both qi and yin after delivery, or female development, especially during lactation, so young and middle-aged women are more likely to suffer from dysentery.

Third, emotional factors:

Long-term anxiety, depression or anger and qi stagnation not only affect the release of liver and qi stagnation, but also damage the transport and transformation of spleen, causing qi stagnation, phlegm stagnation and stagnation in front of neck, forming the cause of Hashimoto's thyroiditis. These are the causes of traditional Chinese medicine.

In western medicine, there are mainly the following points: First, there are many autoantibodies against thyroid components in patients themselves. Second, the evidence of cellular immunity is that there are a large number of plasma cells and lymphocytes infiltrating and lymphoid follicles forming in thyroid tissue. Third, the patient is accompanied by autoimmune diseases, which leads to low resistance. There are also reasons such as pregnancy, long-term overload and fatigue, and working environment that lead to decreased immunity.
