According to the Arthritis Foundation, Rheumatoid Arthritis affects 1.3 million Americans. Although there are several theories, so far, the cause of RA is still unknown. In addition, there is no cure to date, but it is getting easier to control RA through the use of remedies, exercise, and joint protection techniques. Advancements in research and improved options mean that more people with RA are living happier and healthier lives. Here are some facts about Rheumatoid Arthritis from the National Institutes of Health (NIH).What is Rheumatoid Arthritis?
Rheumatoid arthritis (RA) is an inflammatory disease that causes pain, swelling, stiffness, and loss of function in the joints. It occurs when the immune system, which normally defends the body from invading organisms, turns its attack against the membrane lining the joints.
Rheumatoid arthritis generally occurs in a symmetrical pattern, meaning that if one knee or hand is involved, the other one also is. The disease often affects the wrist joints and the finger joints closest to the hand. It can also affect other parts of the body besides the joints. In addition, people with rheumatoid arthritis may have fatigue, occasional fevers, and a general sense of not feeling well.
