| Rheumatoid arthritis |
Also known as inflammatory arthritis, rheumatoid arthritis is among the most debilitating forms of joint disease, causing joints to ache and throb and eventually become deformed. Sometimes these symptoms make even the simplest tasks-like opening a jar or taking a walk-difficult to manage. Unlike osteoarthritis, which results from normal wear and tear on the joints, rheumatoid arthritis is an inflammatory condition. The exact cause is unknown, but it may be caused by the body's immune system attacking the synovium-the tissue that lines the joints. Rhumatoid arthritis is three times more common in women than in men and generally strikes between the ages of 20 and 50. But rheumatoid arthritis also can appear in young children and older adults. There's no cure for rheumatoid arthritis, but with proper treatment, a strategy for joint protection and changes in lifestyle, people with the condition can live a long, productive life. |
