What is Systemic Lupus Erythematosus (SLE) or Lupus?

Lupus (or systemic lupus erythematosis SLE) is an autoimmune disease that occurs when your body’s immune system (auto-antibodies) attacks your own tissues and organs causing inflammation. Every part of your body can be affected but most commonly affected are your joints, skin, kidneys, blood cells, brain, heart and lungs.
