What is Rheumatoid Arthritis?What is Rheumatoid Arthritis (RA)? Well, it is a destructive, inflammatory disease that attacks the synovium, or the lining of joints. RA is felt to be an autoimmune disease, meaning our own immune system is the culprit. Basically the cause of RA is unknown, but it is a global phenomenon, affecting all races, all over the world.
Women are three times more commonly affected than men. Inheritance seems to play a role. Smoking is felt to increase the risk of developing RA. The distribution of RA is estimated to affect 1% of the world population, making an estimated 3 million victims in the USA alone. The disease becomes more prevalent with age. It is estimated that more than 5% of women over the age of 55 suffer from RA.
Typically rheumatoid arthritis has an insidious onset, which means it can develop gradually, to the point where it is well established before being really noticed. It often affects the small joints of the hands, wrists, and feet first, and in a “symmetrical” (same joints on the right and left) pattern. Rheumatoid arthritis can affect every minor and major joint in the body.
