Cholesterol is a fatty substance in the blood. Too much of the harmful type (LDL) can build up in the arteries and raise the risk of heart disease and stroke. High cholesterol usually causes no symptoms.
LDL vs HDL

How It Is Managed
- A diet lower in saturated fat and higher in fibre
- Regular physical activity and weight management
- Quitting smoking
- Medication such as statins when prescribed
- Periodic lipid profile tests
