Carotid artery narrowing is a common condition where the carotid arteries, which are located on either side of your neck, become narrowed or blocked due to the buildup of plaque.

This plaque buildup is caused by a combination of factors such as high blood pressure, high cholesterol, diabetes, smoking, and a family history of the disease. When the arteries become narrowed, it can increase your risk of having a stroke.

What Causes Carotid Artery Narrowing?

The exact cause of carotid artery narrowing is not known, but it is believed to be a result of several factors including:.

  • High blood pressure
  • High cholesterol
  • Smoking
  • Diabetes
  • Age
  • Family history of the disease
  • Obesity
  • A sedentary lifestyle

What are the Symptoms of Carotid Artery Narrowing?

Many people with carotid artery narrowing have no symptoms, but some may experience:.

  • Weakness or numbness in the face, arm, or leg
  • Difficulty speaking or understanding speech
  • Loss of vision in one or both eyes
  • Dizziness or loss of balance
  • Sudden severe headache

If you experience any of these symptoms, seek medical attention immediately.

How is Carotid Artery Narrowing Diagnosed?

Your doctor may recommend several tests to diagnose carotid artery narrowing, including:.

  • Carotid ultrasound
  • Magnetic resonance angiography (MRA)
  • Computerized tomography angiography (CTA)
  • Angiogram

What is the Treatment for Carotid Artery Narrowing?

The treatment for carotid artery narrowing depends on the severity of the blockage and your overall health. Your doctor may recommend:.

  • Lifestyle changes: Stopping smoking, losing weight, exercising, and eating a healthy diet
  • Medications: Blood thinners, antiplatelet drugs, cholesterol-lowering medications, and medications to lower blood pressure
  • Surgery: Carotid endarterectomy or carotid stenting may be recommended for severe cases of carotid artery narrowing

What is the Stroke Risk for Carotid Artery Narrowing?

The risk of stroke with carotid artery narrowing varies depending on the severity of the blockage. Studies have shown that people with severe carotid artery narrowing have a higher risk of stroke than those with mild or no blockage.

However, not all people with severe carotid artery narrowing will have a stroke and not all strokes are caused by carotid artery narrowing.

How Can You Lower Your Risk of Stroke?

If you have carotid artery narrowing, there are several things you can do to lower your risk of stroke:.

  • Take your medications as prescribed
  • Eat a healthy diet
  • Exercise regularly
  • Quit smoking
  • Manage your blood pressure and cholesterol levels

It’s important to work with your doctor to create a treatment plan that is right for you and to closely monitor your condition to prevent stroke.

Conclusion

By making lifestyle changes, taking medications as prescribed, and closely monitoring your condition, you can lower your risk of stroke and maintain a healthy life.
