An<unk>  is a condition arising from an abnormal immune response to a functioning body part. There are at least 80 types of<unk> s. Nearly any body part can be involved. Common symptoms include low grade fever and feeling tired. Often symptoms come and go. The cause is unknown. Some<unk> s such as lupus run in families, and certain cases may be triggered by infections or other environmental factors. Some common<unk> s that are generally considered<unk>  include celiac<unk> , diabetes mellitus type 1, Graves'<unk> , inflammatory bowel<unk> , multiple sclerosis, psoriasis, rheumatoid arthritis, and systemic lupus erythematosus. The diagnosis can be difficult to determine. Treatment depends on the type and severity of the condition. Nonsteroidal anti-inflammatory drugs (NSAIDs) and immunosuppressants are often used. Intravenous immunoglobulin may also occasionally be used. While treatment usually improves symptoms, they do not typically cure the<unk> . About 24 million (~7.5%) people in the United States are affected by an<unk> . Women are more commonly affected than men. Often they start during<unk> ulthood. The first<unk> s were described in the early 1900s.
