The onset of rheumatoid arthritis may be related to environmental and genetic factors, but the specific cause of the disease has not been clarified, and the pathogenesis has not yet been elucidated, and is currently believed to be related to T-cell activation and autoimmune response. Common symptoms of rheumatoid arthritis are joint deformity, swelling, pain and morning stiffness, and patients with severe conditions may have difficulty in joint movement. There is no effective cure for rheumatoid arthritis, but regular and effective treatment can effectively prevent the progression of the disease and improve the quality of life of patients. If not treated in time, the disease may involve the heart, lungs, kidneys and other organs, further damaging the health of patients. Rheumatoid arthritis patients are advised to go to the rheumatology and immunology department of regular hospitals for detailed consultation.
