Atherosclerosis is a medical condition in which the arteries become narrowed and hardened due to the buildup of fatty deposits called plaques on their inner walls. This can reduce or block blood flow, leading to serious health problems.
Causes
- High cholesterol – Excess LDL (“bad”) cholesterol contributes to plaque formation.
- High blood pressure – Damages artery walls, making plaque buildup easier.
- Smoking – Accelerates artery damage.
- Diabetes – High blood sugar can damage blood vessels.
- Inflammation and poor diet – Diets high in saturated fats and processed foods increase risk.
Risk Factors
- Age (more common in adults over 40)
- Family history of heart disease
- Obesity
- Sedentary lifestyle
Symptoms
Atherosclerosis often develops gradually and may not cause symptoms until significant blockage occurs. Symptoms depend on the affected arteries:
- Coronary arteries – Chest pain (angina), shortness of breath, heart attack
- Carotid arteries – Stroke, sudden weakness or numbness
- Peripheral arteries – Leg pain when walking (claudication)
- Renal arteries – Kidney dysfunction
Diagnosis
- Blood tests (cholesterol, glucose)
- Imaging tests: ultrasound, CT angiography, MRI
- Coronary angiography for heart arteries
Treatment
- Lifestyle changes
- Healthy diet (low saturated fat, high fiber)
- Regular exercise
- Smoking cessation
- Medications
- Statins (lower cholesterol)
- Blood pressure medications
- Antiplatelet drugs (prevent clotting)
- Surgical procedures (if severe)
- Angioplasty with stent
- Bypass surgery
Prevention Tips
- Maintain a healthy weight
- Exercise regularly (150 minutes/week moderate activity)
- Eat a heart-healthy diet (fruits, vegetables, whole grains, lean protein)
- Avoid smoking and limit alcohol
If you want, I can also make a simple diagram showing how atherosclerosis develops in an artery, which makes it very easy to visualize.
Do you want me to make that diagram?
