Lupus is a complex disease with multiple possible causes. Genetics, environment, diet, medications, female hormones, and sunlight- and often a combination of these- are common triggers of the condition. Most people experience a mild version of lupus in which periodic flare ups are followed by periods without symptoms. In severe cases, symptoms can be debilitating.

Systemic lupus erythematosus (SLE) is the most common type of lupus. While there is no one cause of SLE, environmental and lifestyle choices are likely large contributing factors.

Lupus symptoms and triggers vary widely because they affect so many parts of the body. And since not everyone with lupus has all of the symptoms, and some are similar to signs of arthritis, it can be difficult to diagnose.
