Lupus, an autoimmune disorder, can cause inflammation throughout your body, including in your joints, skin, blood vessels and organs, such as the kidneys. While the cause of lupus is unknown, a combination of genetics, hormones and environmental factors are thought to contribute to its presence.
More than 16,000 new cases are reported each year in the United States. Lupus most often affects women but 10 percent of patients are men.
Medications and lifestyle changes can help control inflammation and minimize organ damage.
