Antibodies against harmful antigens are produced by the body's immune system. An autoimmune disease occurs when the immune system attacks the cells of the body. This hypersensitive response to the body's own tissue is similar to the allergic response.
One theory to explain the cause of autoimmune disorders is that bacteria, viruses or drugs may trigger changes in the immune system. These changes make the immune system unable to distinguish between body tissues.
