Lupus is a chronic, autoimmune disorder that can cause damage to nearly any part of the body. The condition occurs when the immune system mistakenly attacks healthy tissue. This can result in a wide variety of symptoms, and why some health experts may refer to lupus as “a disease with a thousand faces.”
