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.
Signs and Symptoms
Whether or not you have symptoms from FMD depends on the amount of damage to your arteries, and which arteries have been damaged.
Damaged leg arteries may cause leg pain. Damaged arteries to the kidneys may cause high blood pressure or kidney failure.
Damaged carotid arteries may cause dizziness, neck pain, and stroke.
Causes and Risk Factors
The cause of FMD is not yet known.

The most common procedure to diagnose FMD is the following:
A computed tomography (CT) scan may also be used.
There is no cure for FMD. Your doctor will come up with the most effective treatment option for you, which may include:
