🔍 Quick Summary
Atherosclerosis is a condition where fatty deposits (plaque) build up inside arteries.
This narrows blood vessels and reduces blood flow to organs and tissues.
It increases the risk of heart attack, stroke, and circulation problems.
1️⃣ Introduction
Atherosclerosis affects the body’s blood vessels.
• arteries become narrowed and less flexible
• blood flow becomes restricted over time
• symptoms may not appear until the condition is advanced
👉 It is a gradual process that can develop silently for years.
2️⃣ How it happens
Arteries normally carry oxygen-rich blood smoothly.
• fatty deposits (plaque) build up along artery walls
• inflammation and damage make the plaque grow
• arteries narrow and blood flow becomes reduced
👉 Plaque can also rupture, causing sudden blockage.
3️⃣ Types
• Coronary artery atherosclerosis
- affects heart arteries
- may lead to heart attack
• Cerebral artery atherosclerosis
- affects brain circulation
- may lead to stroke
• Peripheral artery atherosclerosis
- affects legs and limbs
- may cause claudication
👉 The location of plaque determines the symptoms and complications.
4️⃣ Common causes
• Lifestyle factors
- smoking
- unhealthy diet high in fats
• Medical conditions
• Other risk factors
- age
- lack of physical activity
👉 These factors damage artery walls and promote plaque buildup.
5️⃣ Symptoms
• often no symptoms early
• chest pain (angina) if heart arteries affected
• leg pain during walking if limb arteries affected
👉 Symptoms usually appear when blood flow becomes significantly reduced.
6️⃣ Associated symptoms
• shortness of breath
• fatigue
• dizziness
• cold or pale limbs
👉 Symptoms depend on which part of the body is affected.
7️⃣🩺 When it becomes dangerous 🚨
• chest pain or pressure
• sudden weakness or speech difficulty
• severe leg pain with pale, cold limb
👉 These may indicate:
• heart attack or stroke
• severe circulation blockage requiring urgent treatment
8️⃣ Management / treatment
• lifestyle changes (diet, exercise, smoking cessation)
• medications to control cholesterol, blood pressure, and blood sugar
• procedures such as angioplasty or surgery in severe cases
Supportive Measures
• eat a balanced, heart-healthy diet
• stay physically active
• maintain healthy weight
• attend regular health check-ups
👉 Early lifestyle changes can slow or prevent progression.

and prevention tips in our Prevention and Wellness section
9️⃣ Diagnosis
• medical history and physical examination
• blood tests (cholesterol, glucose)
• imaging tests such as ultrasound or angiography
👉 Early detection helps prevent complications.
🟢 Important message
Atherosclerosis is a common but preventable condition that develops over time.
Healthy lifestyle choices and early medical care can significantly reduce risks.
👉 Preventing artery damage early is key to avoiding heart attack and stroke.
