Autoimmune disease is a term that covers at least 80 different known conditions. An autoimmune disease or autoimmune disorder occurs when the immune system is unable to distinguish between foreign invaders and healthy tissue, producing antibodies that destroy the body’s own tissue instead of the infection.
Some of the most commonly-recognized autoimmune diseases include lupus, rheumatoid arthritis, ulcerative colitis, Crohn’s disease, celiac disease, psoriasis, and fibromyalgia. Autoimmune diseases can be debilitating and they are difficult to diagnose because symptoms are broad, including fatigue, chronic joint pain, digestive problems, muscle weakness, inflamed skin, hair loss, and chronic, unspecified pain.
