Why Do Doctors Monitor HDL & LDL?

HDL (high density lipoprotein) and LDL (low density protein) are compounds that transport lipids and proteins within the bloodstream. They play a role in the regulation of cholesterol levels in the blood.

  1. Heart Disease

    • Lipoproteins play many roles, but they are usually monitored by doctors because of their effects on cholesterol levels and potential heart disease.

    "Good Cholesterol" and "Bad Cholesterol"

    • In a process known as "Reverse Cholesterol Transport," HDL transports cholesterol from arteries back to the liver, protecting them against further fatty build-up. On the other hand, LDL carries cholesterol from the liver to other tissues in the body, including arteries.

    Recommended Healthy Range

    • To protect against heart disease, it is recommended HDL levels should be maintained above 60mg/dL and LDL levels should remain below 100mg/dL.

    Lifestyle and Diet

    • Lifestyle can have a large impact on HDL levels. Regular exercise, no smoking, healthy weight maintenance, and a balanced diet high in fiber and low in trans fats will help boost HDL. LDL levels can be managed with a combination of pharmaceutical and vitamin supplements.

    Research

    • Results from the Framingham Heart Study demonstrate the risk of cardiovascular disease can be decreased by up to a factor of 10 with a combination of high HDL levels and low LDL levels.
