Which demographic is more commonly affected by fibromuscular dysplasia?

Fibromuscular dysplasia (FMD) is a vascular disorder characterized by abnormal growth or development of the cells in the walls of arteries, leading to stenosis, aneurysms, or dissections. Research indicates that the condition predominantly affects younger females, particularly those between the ages of 15 and 50. This demographic trend is supported by clinical observations and population studies that consistently show a higher prevalence of FMD in women compared to men.

Young males are less commonly affected by this condition, which sets this demographic distinctly apart. Older females and older males are also less likely to present with FMD, as the disease is generally associated with younger patients. The gender disparity in fibromuscular dysplasia may relate to hormonal factors, although the exact mechanism is still under investigation. Overall, understanding that FMD primarily affects young females is crucial for early recognition and treatment, which can significantly impact outcomes for those diagnosed.
