However, researchers have settled on three main theories: Genes About 10 percent of FMD cases occur in members of the same family, suggesting genetics may play a role. In addition, family members can have FMD that affects different arteries. Hormones Women are three to four times more likely to get FMD than men are, which suggests that female hormones may be involved. However, more research is needed to confirm this. While the exact cause of FMD is unknown, there are a few factors that may increase your chance of developing it. These include: being a woman under the age of 50 having one or more family members with the condition smoking Your doctor might suspect that you have FMD after hearing a swooshing sound when listening to your artery with a stethoscope.

Skin changes in color or appearance When to see a doctor If you have fibromuscular dysplasia, seek medical attention immediately if you have any of these signs and symptoms: Sudden changes in your vision Sudden changes in your ability to speak Sudden or new weakness in your arms or legs If you have any of the other signs or symptoms listed and are concerned about your risk of fibromuscular dysplasia, see your doctor.
Fibromuscular dysplasia can be passed down through families inherited. Talk to your doctor about your family health history so together you can be alert to changes that might suggest you have fibromuscular dysplasia. Causes The cause of fibromuscular dysplasia is unknown.
However, several factors may play a role. If someone in your family has fibromuscular dysplasia, you might get the condition, too. It might occur in a different artery or you may have a milder or more severe case. Or, you may never get fibromuscular dysplasia at all. Not everyone who has fibromuscular dysplasia has a relative with the disease. Women have fibromuscular dysplasia more often than men do, so researchers think hormones may play a role in the development of the disease.
But exactly how is unclear. Abnormally formed arteries. A lack of oxygen to the arteries or the use of certain medications or tobacco can cause the arteries to develop abnormally, leading to reduced blood flow.
Sometimes, the arteries may be positioned abnormally. Risk factors Several things can make you more likely to get fibromuscular dysplasia. Women have a much greater risk of fibromuscular dysplasia than do men. Fibromuscular disorder tends to be diagnosed in people in their early 50s. If you smoke, quit. 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 fibromuscular dysplasia. Complications Fibromuscular dysplasia can cause a number of complications. These include: High blood pressure. A common complication of fibromuscular dysplasia is high blood pressure. The narrowing of the arteries causes higher pressure on your artery walls, which can lead to further artery damage, heart disease or heart failure.
Dissected artery. Fibromuscular dysplasia and tears in the walls of your arteries often occur together. This process, called arterial dissection or spontaneous coronary artery dissection SCAD , can limit blood flow to the organ supplied by the injured artery.
This can affect any artery. Fibromuscular dysplasia can weaken the walls of your arteries, creating a bulge called an aneurysm. If an aneurysm ruptures, it can be a life-threatening emergency. An aneurysm can occur in any artery affected by fibromuscular dysplasia. If you have a dissected artery leading to your brain or if an aneurysm in an artery to your brain ruptures, you can have a stroke.
High blood pressure can also increase your risk of a stroke.
