Have you ever heard of a condition called Fibromuscular Dysplasia (FMD)? Probably not. It's a bit of an unusual condition. But it can be very important to know about it. Because it's related to the blood circulation in our body. So today, let's talk about this FMD in a simple way that you can understand.
What is Fibromuscular Dysplasia (FMD)?
Simply put, Fibromuscular Dysplasia , or FMD as we call it, is an abnormal growth of cells in the walls of the arteries in our body. Now you may be wondering what arteries are. Arteries are the blood vessels that carry blood from our heart to all the other tissues in our body. Just like the plumbing system that carries water from a water tank to all parts of the house, these arteries also supply blood to our body.
So, due to this FMD condition, your blood vessels, that is, arteries, can become blocked, swollen, or look like a string of beads, blocked in places and swollen in places . Imagine that if a water pipe is blocked and crushed in places, it will obstruct the flow of water, and this FMD can also obstruct the flow of blood.
Which arteries can be affected by FMD?
This condition, called FMD, can affect arteries in various parts of our body. There are several main types of arteries that can be affected:
- Carotid arteries: These are located in your neck. These arteries carry blood from your heart to your brain. If something happens to these vessels, the amount of blood going to your brain can decrease.
- Renal arteries: These arteries carry blood from your heart to your kidneys, which are important organs that filter waste products from our bodies.
- Coronary arteries: These are the arteries that supply blood to the heart itself. These arteries must be healthy for the heart to function properly.
- Mesenteric arteries: These arteries carry blood to your intestines. They need to function properly to digest the food we eat.
- Other arteries: In addition to this, FMD may also affect the arteries that carry blood to your legs, arms, or other parts of your body.
Who is at higher risk of developing FMD?
FMD can affect anyone, but some people are more likely to develop the condition. Surprisingly, more than 90% of FMD patients are women . It is also most common in people between the ages of 40 and 70 .
Also, there are some other medical conditions that can have similar symptoms to FMD. Therefore, doctors are also concerned about these conditions:
- Ehlers-Danlos syndrome
- Loeys-Dietz syndrome
- Neurofibromatosis type 1
- Williams syndrome
- Vasculitis of large blood vessels (`Large vessel vasculitis`)
- Atherosclerosis
- Systemic arterial mediolysis
How common is FMD?
In fact, it's hard for scientists to say exactly how many people have FMD. Because many people don't have symptoms , or it's discovered incidentally during tests for another condition, you may have the condition, but you may not know it.
What are the main types of FMDs?
FMD can be divided into two main types based on the appearance of the arteries when doctors examine them.
1. Multifocal FMD: This is the most common type . In this type, the arteries look like a string of beads . That is, the arteries are dilated in places, then narrowed, dilated again, narrowed again... in a pattern like that.
2. Focal FMD: This type is much rarer . It involves a blockage of the artery or the formation of abnormal tissue (lesions) in the artery walls.
What causes FMD?
Unfortunately, scientists have not yet found a specific cause for FMD, but several factors are thought to be involved:
- Genetic factors: In some cases, this can be hereditary.
- Hormones: It is suspected that changes in the body's hormone levels may be involved, especially since it is more common among women.
- Damage to the artery wall: Arterial walls can be damaged by things like repeated strain.
- Some factors, such as smoking, can make FMD worse. Therefore, if you smoke, it is very important to quit.
What are the symptoms of FMD?
The symptoms of FMD vary depending on the artery that is affected . Some people with FMD may not have any symptoms at all . However, others may experience symptoms caused by the restriction of blood flow. These include:
- Bruit: When a doctor listens to your neck or abdomen with a stethoscope, an unusual 'swooshing' sound is heard along with the sound of blood flowing.
- Vertigo: A feeling of spinning or spinning around you.
- High blood pressure or uncontrolled blood pressure.
- Migraine headaches.
- Neck pain.
- Hearing a 'swooshing' sound or ringing in the ears.
Imagine, Nilanthi is constantly dizzy, and sometimes she hears a strange noise coming from her ears. She thought this was normal. But when the doctor examined her, he heard a ``Bruit`` sound coming from her neck. It was only after further tests that he discovered that she had FMD.
What serious health problems can FMD cause?
If FMD is not managed properly, it can lead to some serious health problems , so it's important to be aware of this.
- Aneurysm: A weakening of an artery that bulges like a balloon. This can occur in an artery in the brain (a `brain aneurysm`) or an artery in the abdomen (an `abdominal artery aneurysm`). If this ruptures, it can be life-threatening.
- Arterial dissection: A tear in the inner wall of an artery. For example, this can occur in the carotid artery (carotid dissection) or the coronary artery of the heart (spontaneous coronary artery dissection).
- Stroke.
- Transient ischemic attack (TIA), also called a mini-stroke.
These are the main complications that can occur due to FMD. Therefore, it is very important to seek medical advice immediately if you have symptoms.
How is FMD diagnosed?
Sometimes FMD is discovered by chance when a doctor does a routine check-up (for example, hearing a 'bruit' sound). Or it can be discovered during tests for another condition.
If a doctor suspects you have FMD, they may order tests like these:
- CT scan.
- MRI scan (`MRI`).
- Ultrasound scan (`Ultrasound`).
- Angiography: This uses a special substance and X-rays to look at your arteries.
These tests can clearly detect changes in the arteries, blockages, and swelling.
Can FMD be completely cured?
Unfortunately, there is currently no cure for FMD . That is, there is no cure for it. However, treatment can help control symptoms and prevent complications.
What are the treatments for FMD?
Treatments for FMD vary depending on which arteries are affected, the severity of the disease, and your symptoms. The main treatments include:
- Blood thinners (Antiplatelet drugs or Anticoagulant drugs): These prevent blood from clotting and reduce the risk of conditions such as stroke.
- Medications for high blood pressure: For example, medications like `ACE inhibitors` and `Angiotensin receptor blockers`.
- Treatment for headaches and pain: Sometimes things like aspirin or botulinum toxin injections (Botox®) are used.
- Angioplasty: In this procedure, a very small balloon is passed through a catheter into the artery, which is then inflated to open the blocked area.
- Surgery: Surgery may be needed to repair things like aneurysms or create new pathways for blood to flow.
Your doctor will determine the treatment method that is most suitable for you.
Are there ways to prevent FMD?
Since the exact causes of FMD are still unknown, there is no specific way to prevent it . However, it is important to follow a healthy lifestyle, especially avoiding smoking , as smoking can worsen FMD.
What is the life expectancy like with FMD?
Most people with FMD can live a normal life . However, in rare cases, if one of those aneurysms we talked about earlier bursts, it can cause bleeding and stroke, permanent nerve damage, and sometimes even death. That's why it's so important to get proper treatment and follow your doctor's instructions.
If you have FMD, how do you take care of yourself?
If you've been diagnosed with FMD, it's important to take responsibility for your own health. You can do these things:
- Check your blood pressure regularly.
- If you smoke, stop immediately. Also stop using tobacco products. These can worsen FMD.
- Be sure to attend regular medical checkups and appointments. You may need to have an arterial blood pressure test at least once a year.
- Take all medications prescribed by the doctor exactly and on time.
Some people with FMD find it helpful to join support groups where other people with the condition can share experiences, and raise awareness for FMD research.
When should someone with FMD seek medical advice?
Your doctor will let you know what symptoms you should seek medical attention for if you have FMD. This may vary depending on the artery that is affected.
In particular, people with FMD should be aware of the symptoms of stroke . These can occur suddenly:
- Confusion.
- Dizziness, loss of balance, or difficulty walking.
- Severe headache.
- Difficulty speaking or understanding what is being said.
- Vision problems.
- Weakness or numbness in the face, arm, or leg (especially on one side of the body).
If you experience any of these symptoms, you should go to the hospital immediately , as a stroke is an emergency that requires immediate treatment.
The most important things to remember from what we've talked about are:
Okay, so we've talked a lot about fibromuscular dysplasia (FMD) today. Although it's a bit of a complicated topic, I hope you can understand it simply.
FMD is a condition in which cells in the artery walls grow abnormally, causing the arteries to become narrowed, bulging, or appear like a string of beads.
Although the exact cause of this is unknown, some people are at higher risk, especially women. Not everyone gets symptoms, but those who do may experience dizziness, high blood pressure, and a strange noise in their neck. The most dangerous thing is that it can lead to serious conditions like aneurysms and strokes.
Fortunately, this condition can be managed well with proper treatment and lifestyle changes. If you have symptoms related to FMD, be sure to see a doctor. They can then run the necessary tests and prescribe treatments to reduce symptoms and prevent complications. Quitting smoking, controlling blood pressure, and following medical advice are all important for living a healthy life with FMD.
If you have any further questions, don't hesitate to ask your doctor or nurse. Stay healthy!
