Autoimmune diseases are abnormal immune responses in the body that attack normal cells, tissues, or organs. It is estimated currently there are at least 80 autoimmune diseases. AIDs can happen anywhere in the body. The common symptoms include mild fever and feeling tired. Symptoms often appear and resolve rapidly.

The so-called abnormal immunity is to attack parts of human bodies. The antibodies of the immune system in the human body originally attack and eliminate foreign antigens or abnormal cells (such as tumor cells), which is a physiological mechanism to protect the body. However, in some cases, the immune system may produce antibodies against normal cells in its body, causing abnormal excessive inflammation or tissue damage, which in turn affects the health of the body and causes disease.

The etiological causes of AID are still unclear. Certain autoimmune diseases, such as familial lupus erythematosus and, in some cases, are precipitated by infection or other environmental factors. Common diseases include celiac disease, type 1 diabetes, Graves’ disease, inflammatory bowel disease, multiple sclerosis, psoriasis, rheumatoid arthritis, and systemic lupus erythematosus.

Treatment depends on the type and severity of the condition, and nonsteroidal anti-inflammatory drugs (NSAIDs) and immunosuppressants, or targeted drugs, are often used. Treatment improves symptoms, but often does not cure these diseases.

Autoimmune diseases affect a wide range of people, with approximately 24 million (7%) people in the United States affected by autoimmune diseases. It occurs more often in women than in men. It usually begins during adulthood.
