What is Lupus? Symptoms and Causes of Lupus

Lupus is a systemic autoimmune disease that occurs when your body’s immune system attacks your own tissues and organs. Inflammation caused by lupus can affect many different body systems, including your joints, skin, kidneys, blood cells, brain, heart, and lungs. It’s very 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. Some people are born with a tendency toward developing lupus, which may be triggered by infections, certain drugs, or even sunlight. While there’s no cure for lupus, treatments can help control symptoms.
