Lupus erythematosus

Lupus erythematosus

Synonyms: Discoid lupus, SLE, Subacute cutaneous lupus, Systemic lupus erythematosus

DESCRIPTION

The immune system is designed to attack foreign substances in the body. If you have lupus, something goes wrong with your immune system and it attacks healthy cells and tissues.

There are many kinds of lupus. The most common type, systemic lupus erythematosus, affects many parts of the body.

Anyone can get lupus, but it most often affects women. Lupus is also more common in women of African American, Hispanic, Asian, and Native American descent than in Caucasian women.

The cause of lupus is not known. Research suggests that genes play an important role, but genes alone do not determine who gets lupus. It is likely that many factors trigger the disease.
