Systemic Lupus erythematosus (SLE) or “lupus” is a chronic disease that occurs when your body's immune system attacks your own tissues and organs (autoimmune disease). Inflammation caused by lupus can affect many different body systems — including your joints, skin, kidneys, blood cells, brain, heart and lungs.
Lupus can be difficult to diagnose because its signs and symptoms often mimic those of other ailments. The most distinctive sign of lupus — a facial rash that resembles the wings of a butterfly unfolding across both cheeks — occurs in many but not all cases of lupus.
If you have lupus, you may experience periods of illness (flares) and periods of wellness (remission). Lupus flares can be mild to serious, and they are unpredictable. However, with treatment, many people with lupus can manage the disease.
Who gets lupus?
Anyone can get lupus; however, women get the disease about nine times more often than men. Most often it happens in people between ages 15 and 45 years, but lupus can occur in childhood or later in life as well.
Lupus is more common in African Americans than in White people and is also more common in people of American Indian and Asian descent. Men, African Americans, Chinese people, and Hispanic people are also more likely to have serious organ system involvement. If you have a family member with lupus or another autoimmune disease, you may be more likely to develop lupus. (https://www.niams.nih.gov/health-topics/lupus)
