Rheumatoid arthritis (sometimes known as RA) is an autoimmune condition which can cause pain, swelling and stiffness in the joints. The immune system, which normally protects the body from infections, begins to turn against the body's own healthy tissues, particularly causing inflammation of joints. It does this by targeting the synovium, which is the inner surface of the joint capsule. Other organs - such as the lungs, heart and eyes - can sometimes also be affected in rheumatoid arthritis.

Rheumatoid arthritis affects almost half a million people in the United Kingdom. Although it predominantly affects women aged between 40 and 50, it can affect anyone of any age. The disease can rapidly worsen causing joint damage therefore prompt and effective treatment is important. Treatment often starts with anti-inflammatories, usually steroid tablets or injections, and early initiation of disease modifying anti-rheumatic drugs (DMARDs) which are effective in autoimmune conditions. The earlier you are diagnosed and start treatment, the more effective it’s likely to be.
