Autoimmune Disease

Autoimmune disease is a condition in which the body's immune system mistakenly attacks healthy cells and tissue. This type of condition can affect any organ or system in the body, and can range from mild to life-threatening. The cause of autoimmune disease is unknown, though genetics, environmental factors, and infection are thought to be important contributors. When the body is exposed to a foreign substance, such as a virus, its immune system will produce antibodies to fight off the invader. In some cases, however, the immune system will mistakenly make antibodies that attack the body's own healthy cells and tissue. This can lead to inflammation and damage to organs and other parts of the body. There are many different types of autoimmune diseases, some of which include lupus, rheumatoid arthritis, type 1 diabetes, and multiple sclerosis. Symptoms vary depending on the type of disease and can include fatigue, joint pain and swelling, skin rashes, fever, and muscle and joint stiffness. Treatment for autoimmune diseases is often focused on controlling the symptoms and preventing further damage. This can include medications that suppress the immune system, physical therapy, and lifestyle changes.
