Lupus is a chronic autoimmune disease, which causes inflammation of various parts of the body, especially the skin, joints and kidneys. It may also affect the blood. The immune system normally protects the body against viruses, bacteria and other foreign invaders. In an autoimmune disease like lupus, the immune system loses its ability to tell the difference between foreign substances and its own cells and tissues. The immune system then makes antibodies directed against the body itself.
