Causes

The cause of fibromuscular dysplasia is unknown. However, several factors might play a role.

• Hormones. Researchers think female hormones might play a role in the development of the disease. Fibromuscular dysplasia is not linked to women's use of birth control pills, number of pregnancies, or age when they gave birth.
• Genetics. If someone in your family has fibromuscular dysplasia, you might get the condition, too.
