An autoimmune disease is a condition in which your immune system mistakenly attacks your body. The immune system normally guards against germs like bacteria and viruses. When it senses these foreign invaders, it sends out an army of fighter cells to attack them.
What Causes Autoimmune Disease? No one is really sure what exactly is responsible for causing autoimmune disease. However, doctors have several theories of what may be causing them, such as a virus or bacteria that confuses the immune system and makes it think that healthy tissue is actually an antigen, which in turn causes the immune system to attack perfectly healthy tissue.
