Although the cause of fibromuscular dysplasia is unknown, there are several factors that appear to increase the risk of developing the disorder, including:

  • Sex. Women have a much greater risk of fibromuscular dysplasia than do men.
  • Age. Fibromuscular disorder tends to be diagnosed in people in their early 50s.
  • Smoking. People who smoke appear to have an increased risk of developing fibromuscular dysplasia. For those already diagnosed with the disease, smoking is a risk factor for more serious fibromuscular dysplasia.
