Wonder what causes lupus? Lupus, an autoimmune disease, happens when the immune system attacks its tissues, causing inflammation, swelling, pain, and damage. Lupus symptoms vary, and early lupus symptoms include fatigue, joint pain, fever, and a lupus rash, especially after being in the sun. Familiarize yourself with pictures of the lupus rash. Doctors diagnose lupus by symptoms and blood tests. Lupus is not contagious but has a hereditary component, so family health information is important.
