Systemic Lupus Erythematosus (SLE), commonly referred to as “lupus”, is an autoimmune disease that has the potential to affect any organ system in the body. Like other autoimmune diseases, lupus occurs when the body attacks itself. The most commonly affected areas of the body include the skin, joints, kidneys, blood vessels, brain, heart and lungs. Although lupus can be diagnosed at any age, the average age of onset is 31 years old1.
There are four types of lupus: systemic lupus erythematosus, discoid lupus, drug-induced lupus and neonatal lupus. Although they can have overlapping symptoms, systemic lupus erythematosus is the most serious and the most common.
