Firstly, rheumatoid patients do not necessarily progress to severe disease, and secondly, the time from early stage to severe disease in rheumatoid patients is related to whether the patients receive standardized treatment, sensitivity to drugs and specific conditions, so it is impossible to make a generalization. Rheumatoid arthritis is a common chronic connective tissue disease that causes systemic joint damage. The main pathological changes are chronic inflammation of the synovial membrane, formation of vascular opacities, destruction of cartilage and subchondral bone, which eventually leads to joint deformity, ankylosis and loss of function. There is no good cure for this disease, but if detected early and treated reasonably, more than 80% of patients can control the symptoms and spread of the disease, and those with mild symptoms can achieve clinical recovery. Some patients may also develop severe joint damage within 3-5 years due to factors such as cold, infection, and exertion, when the disease is more serious. Once rheumatoid arthritis is diagnosed, reasonable treatment is the key, and it is also recommended that patients should live in a dry, sunny environment and participate in outdoor activities frequently to enhance their physical fitness.
