Lupus is a chronic autoimmune disease that causes inflammation. It can damage many parts of the body, including the joints, skin, kidneys, heart, lungs, blood vessels, and brain. A type of lupus known as discoid lupus causes red rashes on skin (especially on face or hands) which do not go away easily. The rashes become well defined, thickened and scaly with time and worsen on exposure to sunlight. Red or purple lines or spots appear in fingernail folds or on the tips of fingers.

Our immune system is made to fight dangerous infections and bacteria to keep our body healthy. An autoimmune disease occurs when the immune system attacks the body's own cells because it confuses it for a foreign matter. There are many autoimmune diseases, and systemic lupus erythematosus (SLE) is one of them.
