Autoimmune diseases arise when the immune system attacks one or more of the body's normal constituents as if they were invaders. When the immune system fails to recognize self it may produce immune cells or antibodies (called autoantibodies) that target its own cells, tissues, and/or organs. Those attacks cause inflammation and tissue damage that lead to autoimmune disorders. There are over 80 diseases that occur as a result of autoimmune responses. The National Institutes of Health (NIH) estimates that 23.5 million Americans are affected.
