Degenerative stenosis of the vertebral artery is a condition characterized by the narrowing of the blood vessels that supply the brain with oxygen. In simple terms, it restricts blood flow to the brain due to the degeneration of the vertebral arteries. This article aims to provide a comprehensive overview of this condition in plain English, making it easily accessible to all readers.
Types:
There are two main types of degenerative stenosis of the vertebral artery: atherosclerotic stenosis and non-atherosclerotic stenosis. Atherosclerotic stenosis occurs when fatty deposits, known as plaque, build up inside the arteries, while non-atherosclerotic stenosis is caused by structural changes in the artery itself.
Causes:
- Aging: The natural aging process can lead to wear and tear on the vertebral arteries.
- Hypertension: High blood pressure puts additional stress on the arterial walls.
- Smoking: Tobacco use contributes to the development of atherosclerosis.
- Diabetes: Uncontrolled diabetes can damage blood vessels over time.
- High cholesterol: Elevated levels of cholesterol may lead to plaque formation.
- Genetics: A family history of vascular diseases can increase the risk.
- Obesity: Excess body weight is linked to various cardiovascular issues.
- Sedentary lifestyle: Lack of physical activity can contribute to arterial degeneration.
- Inflammation: Chronic inflammatory conditions may affect artery health.
- Poor diet: A diet high in saturated fats and low in nutrients can contribute to arterial damage.
- Stress: Prolonged stress may impact blood vessel health.
- Drug abuse: Substance abuse, especially stimulants, can affect arteries.
- Trauma: Past injuries to the neck or head may contribute to stenosis.
- Infections: Certain infections can lead to inflammation and artery damage.

- Hormonal changes: Fluctuations in hormones, especially in women, may play a role.
- Medications: Some drugs may have side effects that impact vascular health.
Symptoms:
