What is Cholesterol?
Cholesterol is a waxy substance found in the fats (lipids) in your blood. Your body needs cholesterol to build healthy cells, but high levels can increase your risk of heart disease.
Cholesterol comes from two main sources: liver production (about 75%) and dietary intake (about 25%). Understanding different types of cholesterol is crucial for cardiovascular health.
Types of Cholesterol
🔴 LDL (Low-Density Lipoprotein) - "Bad" Cholesterol
LDL builds up in artery walls forming plaque, increasing heart disease and stroke risk. Goal: The lower, the better
🟢 HDL (High-Density Lipoprotein) - "Good" Cholesterol
HDL helps remove LDL from your blood, transporting it back to the liver for breakdown. Goal: The higher, the better
🟡 Triglycerides
Triglycerides are another type of fat in your blood. High levels increase cardiovascular disease risk. Goal: Keep within normal range
