Cause of Rheumatoid Arthritis
The exact cause of rheumatoid arthritis (RA) is not fully understood, but it is believed to be a combination of genetic and environmental factors. RA is an autoimmune disease, meaning the immune system mistakenly attacks healthy joints, causing inflammation and pain. Genetic factors play a role, as certain genes can increase the likelihood of developing RA. Environmental triggers, such as infections, smoking, and hormonal changes, may also contribute to the onset of the disease. While the precise cause remains unclear, ongoing research continues to explore how genetic and environmental factors interact in the development of rheumatoid arthritis.
