What causes fibromuscular dysplasia?

The cause of fibromuscular dysplasia is unknown. It is likely that there are many factors that contribute to the development of this condition. These factors may include blood vessel abnormalities, tobacco use, hormone levels, and genetic predispositions. Approximately 28 percent of affected individuals have more than one artery with fibromuscular dysplasia. It is not known why some people develop this condition in more than one artery.[1]
