The causes of rheumatoid arthritis (RA) is unknown although genetics and environment probably play a part. Researchers believe that genetics may predispose some people to rheumatoid arthritis. In those people, environmental factors, bacteria, and viruses may then trigger RA. Some evidence suggests that hormones may also play a role, but researchers aren’t sure. In RA, the body’s immune system–which normally fights off foreign invaders–mistakenly attacks the lining of the joints called synovium. That causes inflammation, which thickens the synovium and eventually destroys the cartilage and bone in the joints.
There are several factors that may increase your risk of rheumatoid arthritis include:
Women are more likely to develop rheumatoid arthritis than men are.
Rheumatoid arthritis can occur at any age, but it most commonly begins between the ages of 40 and 60.
* Family history
If a member of your family has rheumatoid arthritis, you may have an increased risk of the disease. Doctors don’t believe you can directly inherit rheumatoid arthritis. Instead, it’s believed that you can inherit a predisposition to rheumatoid arthritis.
Smoking cigarettes increases your risk of rheumatoid arthritis. Quitting can reduce your risk.
Interferon-alpha, a drug used to treat hepatitis, autoimmune diseases, and other diseases has triggered RA in rare cases.
