What is Rheumatoid Arthritis?

Rheumatoid arthritis (RA) causes tissues lining the joints to become swollen, stiff, and painful (inflamed).

Over time, this inflammation may destroy the joint tissues. This can limit your daily activities and make it hard for you to walk and use your hands.

Rheumatoid arthritis is 2 to 3 times more common in women than in men. It often begins between the ages of 40 and 60.

What Causes Rheumatoid Arthritis?

The exact cause of rheumatoid arthritis is not known. But rheumatoid arthritis is an autoimmune disease. This means that the body's natural defense system attacks the joints. The disease also runs in some families.

How is it Treated?

There is no cure for rheumatoid arthritis, but treatment may help relieve symptoms and control the disease. Treatment usually continues throughout your life.

Treatment includes medicine, exercise, and lifestyle changes.
