Carotid Stenosis

Carotid stenosis is a medical condition that affects the carotid arteries in your neck, which are vital for supplying blood to your brain. When these arteries become narrow or blocked, it can lead to serious health problems, including strokes. In this article, we’ll explain carotid stenosis, its types, causes, symptoms, diagnostic tests, treatments, drugs, and surgical options in simple language to help you understand this condition better.

Carotid stenosis happens when the carotid arteries get clogged or narrowed. These arteries carry blood from your heart to your brain, and when they’re not working well, it can be a problem.

Types of Carotid Stenosis:

There are two main types:

1. Atherosclerotic Stenosis: This occurs when fatty deposits build up in the arteries over time, making them narrower.
2. Fibromuscular Dysplasia: This is a rare condition where the artery walls become abnormal and narrow.

Causes of Carotid Stenosis 

1. Smoking: Smoking can damage your arteries and lead to blockages.
2. High Blood Pressure: High blood pressure can harm your arteries over time.
3. Diabetes: Uncontrolled diabetes can affect your arteries’ health.
4. High Cholesterol: Too much cholesterol can build up and narrow the arteries.
5. Obesity: Being overweight increases the risk of carotid stenosis.
6. Age: As you get older, the risk of artery blockages increases.
7. Family History: If your family has a history of carotid stenosis, you might be more likely to get it.
8. Gender: Men tend to be at a higher risk than women.
9. Race: Some races are more prone to carotid stenosis.
10. Lack of Exercise: Not being active can affect artery health.
11. Alcohol Consumption: Excessive drinking can raise your risk.
12. Illegal Drug Use: Some drugs can harm your arteries.
13. Stress: High stress levels may impact your arteries.
14. Poor Diet: A diet high in unhealthy fats can contribute.
15. Sleep Apnea: This condition can affect your blood vessels.
16. Infections: Certain infections can harm your arteries.
17. Inflammatory Diseases: Conditions like rheumatoid arthritis can be a risk factor.
18. Radiation Exposure: Previous radiation therapy to the neck can increase risk.
19. Blood Clotting Disorders: Some disorders make clots form more easily.
20. Cervical Artery Dissections: Tears in the artery lining can lead to blockages.
