How is rheumatoid disease caused?

Rheumatoid arthritis is caused by wind, cold and dampness, which are external factors. In addition, rheumatoid arthritis is related to physical factors. Traditional Chinese medicine says that qi exists inside, evil cannot dry; where evil gathers, qi must be deficient, that is, when the body is weak, it is easy to feel external evil, which is easy to cause this disease. In addition, according to the age of onset of rheumatoid arthritis, most of the disease is related to endocrine factors before and after menopause. There is also a genetic factor, although the disease is not absolutely inherited. However, some patients carry susceptibility genes. once they carry the human leukocyte antigen HL gene, they are prone to rheumatoid arthritis.
