Overview of Autoimmune Diseases

The term "autoimmune disease" refers to a varied group of more than 80 serious, chronic illnesses that involve almost every human organ system. In all of these diseases, the underlying problem is similar--the body’s immune system becomes misdirected, attacking the very organs it was designed to protect. About 75% of autoimmune diseases occur in women, most frequently during the childbearing years. Autoimmune diseases can affect connective tissue. (This is the tissue which binds together various tissues and organs.) It can also affect the nerves, muscles, endocrine system, and gastrointestinal system.
