🔍 Quick Summary
High cholesterol is a condition where fats in the blood are elevated.
It often has no symptoms—but increases the risk of heart disease over time.
1️⃣ Introduction
Cholesterol is a fatty substance found in the blood.
• needed for normal body functions
• produced by the liver and obtained from food
• becomes harmful when levels are too high
👉 High cholesterol is often silent—but its effects build over time.
2️⃣ How it happens
Cholesterol travels in the blood in different forms.
• LDL (“bad” cholesterol) can build up in arteries
• HDL (“good” cholesterol) helps remove excess cholesterol
• imbalance leads to plaque formation
👉 Over time, arteries can narrow and restrict blood flow.
3️⃣ Classification
• High LDL cholesterol
- increases risk of heart disease
- contributes to artery blockage
• Low HDL cholesterol
- reduces protection
- allows cholesterol to accumulate
👉 The balance between types is important.
4️⃣ Common causes
• Lifestyle factors
- high-fat diet
- lack of physical activity
• Medical factors
- genetics (family history)
- conditions like diabetes
5️⃣ Symptom explanation

7️⃣🩺When it becomes dangerous 🚨
