Rheumatoid Arthritis

Rheumatoid arthritis, or RA, is an autoimmune and inflammatory disease, which means that your immune system attacks healthy cells in your body by mistake, causing inflammation (painful swelling) in the affected parts of the body. RA mainly attacks the joints, usually many joints at once.
A chronic inflammatory disorder affecting many joints, including those in the hands and feet. In rheumatoid arthritis, the body’s immune system attacks its own tissue, including joints. In severe cases, it attacks internal organs. Rheumatoid arthritis affects joint linings, causing painful swelling. Over long periods of time, the inflammation associated with rheumatoid arthritis can cause bone erosion and joint deformity.

About 40 percent of the people who have rheumatoid arthritis also experience signs and symptoms that don’t involve the joints. Rheumatoid arthritis can affect many organs, including: Skin eyes lungs heart kidney salivary glands nerve tissue bone marrow blood vessels.

Rheumatoid arthritis signs and symptoms may vary in severity and may even come and go. Periods of increased disease activity, called flares, alternate with periods of relative remission — when the swelling and pain fade or disappear. Over time, rheumatoid arthritis can cause joints to deform and shift out of place.
