Lupus is a chronic autoimmune disease that causes the immune system to attack healthy tissue resulting in inflammation, particularly of the skin, joints, kidneys, heart, lungs, blood vessels and brain. It develops most commonly in women between the ages of 15-45, and occurs more often in African-American, Hispanics, Native Americans and Asians. Men can get lupus too. Lupus is not infectious or cancerous. People with lupus may have many different symptoms affecting various parts of the body. Some of the most common symptoms are extreme fatigue, painful or swollen joints (arthritis), unexplained fevers, skin rashes and kidney problems. Lupus is characterized by "flares" or periods of illness and remission. Warning signs of a flare can be increased fatigue, pain, rash, fever, abdominal discomfort, headache or dizziness. Learning how to recognize these signs can help people maintain better health and reduce or ward off a flare. Currently, there is no cure for lupus but it can be managed effectively with drugs, and most people with lupus lead an active, healthy life.
