Exposure to sunlight is an example of a trigger that might cause individuals who are susceptible to the disease to develop skin lesions and other symptoms of lupus, notes Mayo Clinic. Certain medications can also act as a trigger, particularly blood pressure medications, anti-seizure medications and antibiotics. In such cases, the symptoms of the disease often subside when the individual stops taking the medicine that is causing the reaction.

According to WebMD, the symptoms of lupus include feeling tired, having joint pain or swelling, developing a fever or a rash, experiencing hair loss and developing mouth sores. Over time, those with lupus might also develop problems with their heart, kidneys, lungs, nervous system or blood cells. Lupus can be difficult to diagnose, and it affects different people in different ways. Doctors generally use urine and blood tests to check for lupus, and treatment for the disease can include steroid creams to treat rashes, medicines that minimize joint pain and immunosuppressants.
