Lupus is an autoimmune disease that causes inflammation throughout the body. An autoimmune disease is a condition where the body’s own immune system is responsible for the inflammation and breakdown of its own cells. The inflammation seen in lupus can affect various organs and tissues of the body including the joints, skin, heart, blood, lungs, brain, and kidneys. While this disease can be severe and life threatening with permanent organ damage, many patients experience a mild version of the disease. Currently, there is no known cure for lupus.
