Risk factors

Several things may make you more likely to develop fibromuscular dysplasia.

• Sex. Fibromuscular dysplasia is more common in women than it is in men.
• Age. Although it can affect people of any age, fibromuscular dysplasia tends to be diagnosed in people in their 50s.
• Smoking. People who smoke appear to have an increased risk of developing fibromuscular dysplasia. For those already diagnosed with the disease, smoking increases the risk for more-serious disease.
