Overview

What Is Fibromuscular Dysplasia?

Fibromuscular dysplasia (FMD) is a disorder that causes some of your body’s arteries to develop improperly. Fibrous tissue grows in the walls of the arteries, causing narrowing (stenosis). This causes less blood to be able to flow through the arteries, increasing the risk of stroke.

FMD usually affects the arteries that supply blood to your kidneys. However, it may also affect your carotid artery, which supplies blood to your brain.
