Systemic Lupus Erythmatosus (SLE)

Systemic lupus erythematosus (SLE), also known simply as lupus, is an autoimmune disease. In this disease, the body's immune system mistakenly attacks healthy tissue. It can affect the skin, joints, nervous system, brain, kidneys, heart and lungs. Common symptoms include painful and swollen joints, fever, chest pain, hair loss, mouth ulcers, swollen lymph nodes, feeling tired, and a red rash which is most commonly on the face (discoid lupus).
