Lupus is an autoimmune disease, meaning that the body's immune system mistakenly attacks healthy organs and tissue. Lupus can affect any part of the body, causing inflammation and damage in joints, skin, kidneys, heart, lungs, blood vessels, or the brain. More than 90% of people with lupus have skin rashes, often triggered by exposure to the sun. About half have kidney and lung problems.
