What causes rheumatoid arthritis?

The causes of rheumatoid arthritis may include genetic factors, environmental influences, immune system abnormalities and infections, etc. Its pathogenesis is complex and is usually the result of the combined action of multiple factors.

Rheumatoid arthritis is somewhat related to genetics. Some patients carry specific genes (such as HLA-DR4), which increases the risk of disease. At the same time, environmental factors cannot be ignored. Cold and humid climates may induce symptoms. Immune system abnormalities play a central role in the disease. When the immune system attacks normal joint tissue, it leads to inflammation and joint damage. Infectious factors may also stimulate the occurrence of rheumatoid arthritis. For example, patients may be infected by pathogens such as streptococci, thereby inducing an immune response. Changes in hormone levels and the effects of physiological factors such as stress on immune function may also be related to the occurrence of the disease. The prevalence rate is higher in long-term smokers, suggesting that lifestyle is also a key factor.

To prevent rheumatoid arthritis, risk factors need to be controlled. Maintain a suitable living environment and avoid being in a cold and damp state for a long time; pay attention to hygiene and prevent infection, especially respiratory pathogen infection; develop healthy living habits, quit smoking and limit alcohol, maintain a balanced diet, and consume a moderate amount of foods rich in Omega-3 fatty acids, such as deep-sea fish, which can help suppress inflammation. For people with a family history, regular checks and assessments of their immune function can be performed. Once joint swelling or obvious pain occurs, they should seek medical attention as soon as possible and seek professional diagnosis and treatment. Improving immunity and early detection of potential symptoms are key steps in controlling rheumatoid arthritis.
