While the cause of rheumatoid arthritis is not clear, it is believed to involve a combination of genetic and environmental factors. The underlying mechanism involves the body's immune system attacking the joints. This results in inflammation and thickening of the joint capsule. It also affects the underlying bone and cartilage.
The specific cause of rheumatoid arthritis has yet to be identified despite decades of medical research. While we donât know specifically what causes rheumatoid arthritis, we do know that it is the result of an autoimmune disorder. An autoimmune disorder occurs when immune cells begin to attack the body. In the case of rheumatoid arthritis, the body attacks its own healthy joint tissue called the synovium. The synovium is what produces a clear liquid substance known as synovial fluid. This fluid lubricates healthy joints and gives cartilage and bones the nourishment required to remain effective and mobile.
