Autoimmune diseases encompass a vast array of disorders in which an overactive immune system attacks its own cells and tissues leading to devastating consequences. In other words, your body damages and fights against itself.  Researchers have identified greater than 100 different autoimmune diseases which are often chronic, debilitating and life threatening. The standard treatment for most cases of autoimmune diseases is some form of immunosuppression or steroid treatment to keep the immune system under control. Often the long term side effects of these treatments outweigh the benefits.
