Interactive FAQ
What is the difference between LDL and HDL cholesterol?
LDL and HDL are both lipoproteins that carry cholesterol through your bloodstream. LDL carries cholesterol to your tissues, while HDL carries cholesterol away from your tissues to your liver for excretion. High LDL levels can increase your risk of heart disease, while high HDL levels can decrease your risk.
