What is Lupus?

Lupus is a chronic inflammatory disease marked by its effect on various parts of the body, including the joints, skin, blood, and kidneys. It is a condition in which the body's immune system attacks its own cells and tissues, resulting in pain, inflammation, and often damage to organs.

There are many kinds of lupus. The most common type, systemic lupus erythematosus, affects many parts of the body. Discoid lupus causes a rash that doesn't go away. Subacute cutaneous lupus causes sores after being out in the sun. Another type can be caused by medication. Neonatal lupus, which is rare, affects newborns.

For many people, the disease is mild and affects only a few organs. For others, however, the disease can be severe and even life threatening.
