What causes lupus?
The cause of lupus is not known. It is likely that there is no single cause but a combination of genetic, environmental, and possibly hormonal factors that work together to cause the disease. Lupus is not contagious-you can’t catch it from someone. No specific “lupus gene” has been found, but it does run in families.
Lupus is NOT infectious, rare or cancerous. Researchers do not know what causes lupus. While scientists believe there is a genetic predisposition to the disease, it is known that environmental factors also play a role in triggering the disease. Some of the factors that may trigger lupus include infections, antibiotics, ultraviolet light, extreme stress, certain drugs, and hormones. Hormonal factors may explain why lupus occurs more frequently in females than in males.
