Lupus is a chronic inflammatory disease that is also classified as an autoimmune disease. Autoimmune diseases occur when the cells of the immune system receive misguided messages to attack the body’s own healthy tissues in addition to targeting invading foreign substances. The inflammation caused by lupus can affect all parts of the body, including the joints, skin, kidneys, blood cells, heart, and lungs.
There are four types of lupus, of which systemic lupus erythrematosus is both the most common and most serious form. The specific symptoms experienced will vary depending on the individual and the body systems affected. Common symptoms include fatigue; fever; joint pain, swelling, and stiffness; facial rash or skin lesions, among many others.
