Autoimmune Disease

Rheumatoid arthritis

Rheumatoid arthritis (RA) is a form of arthritis that causes pain, swelling, stiffness and loss of function in your joints. It can affect any joint but is common in the wrist and fingers. More women than men get rheumatoid arthritis. It often starts between ages 25 and 55. You might have the disease for only a short time, or symptoms might come and go. The severe form can last a lifetime.

Rheumatoid arthritis is different from osteoarthritis, the common arthritis that often comes with older age. RA can affect body parts besides joints, such as your eyes, mouth and lungs. RA is an autoimmune disease, which means the arthritis results from your immune system attacking your body's own tissues.

March is Autoimmune Disease
Awareness Month!

Autoimmune diseases result from a dysfunction of the immune system. The immune system protects you from disease and infection. Sometimes, though, the immune system can produce autoantibodies that attack healthy cells, tissues, and organs. This can lead to autoimmune disease.

Autoimmune diseases can affect any part of the body. More than 80 autoimmune diseases have been identified. Some are relatively well known, such as type 1 diabetes, multiple sclerosis, lupus, and rheumatoid arthritis, while others are rare and difficult to diagnose.

Collectively, autoimmune diseases are among the most prevalent diseases in the U.S., affecting more than 23.5 million Americans. They are more common among women, and while some are more prevalent among white people, others are more common among African-Americans and Hispanics. Autoimmune diseases are becoming increasingly prevalent, for reasons unknown.

Some autoimmune diseases are life-threatening, and most are debilitating and require a lifetime of treatment. There are treatments available to reduce the symptoms and effects from many autoimmune diseases, but cures have yet to be discovered. Since most autoimmune diseases are rare, patients can often spend years seeking a proper diagnosis.
