Rheumatoid arthritis is an autoimmune disease that attacks the joints. Although it shares some symptoms with osteoarthritis, the type of arthritis that usually occurs in older people due to wear and tear on joints, there are some key differences. Rheumatoid arthritis can attack at any age, can come on rapidly, and may be accompanied by other symptoms, such as fatigue.
More than 1 in 5 adults in the U.S. have arthritis or other joint-damaging conditions, and the ongoing obesity epidemic may be partly to blame, according to a report issued today by the Centers for Disease Control and Prevention (CDC).
A simple blood test may allow doctors to identify a debilitating form of arthritis years before any symptoms appear, which may help to stop the disease in its tracks
