Guide To The Most Common Autoimmune Diseases

Autoimmune diseases are a category of conditions where an individual's immune system acts abnormally, often attacking and destroying healthy tissues by mistake. Many triggers can cause an individual's body to start making components referred to as antibodies. Usually, antibodies help the body fight off infections. However, in patients with an autoimmune disease, they attack the body's healthy tissues instead. Diagnoses are made using physical examination, thorough medical history, blood tests, urine tests, and tissue biopsies.
