What Causes Lupus?
The cause of systemic lupus is unknown. Experts believe that it occurs due to a combination of genetics (having an inherited predisposition for developing it) and a person’s environment and lifestyle.
Possible causes/triggers of lupus include exposure to sunlight, tobacco consumption, and the use of certain blood pressure drugs, anti-seizure medications, and antibiotics. Symptoms may persist even after these drugs are stopped. Some infections may cause lupus.
