Rheumatoid arthritis (RA) is an autoimmune disease that causes inflammation of the joints. Because many symptoms of RA are similar to those of a variety of other diseases, diagnosis can be difficult. A correct diagnosis requires clinical evaluation, X-rays, and a series of laboratory tests.
Autoimmune diseases cause your bodyâs immune system to mistakenly attack normal cells. In autoimmune arthritis, such as rheumatoid arthritis (RA), your immune system attacks the lining of your joints. This leads to inflammation that can affect your entire body. Symptoms vary greatly from person to person, as does the rate of progression.
