What Does Cholesterol Do?

Cholesterol is used in cell membranes, learning and memory skills, digestion and synthesis of bile acids, and Vitamin D.

What is LDL?

LDL is a low-density lipoprotein that is processed in the bloodstream.  When not monitored, it accumulates on the artery wall and forms plaque.

What is HDL?

HDL is a high-density lipoprotein that picks up cholesterol from the LDL and takes it back to the liver.  It helps to regulate LDL levels in the blood.

Why Do My LDL/HDL Levels Matter?

High LDL results in a buildup of plaque and a high risk for heart disease.

Low HDL levels mean LDL is not being taken out of the bloodstream.

High LDL and low LDL will almost always occur together.

What Else Is Monitored With My Cholesterol?

Doctors will also monitor the triglycerides in the blood.  High triglycerides usually means overall high cholesterol.

What Impact Do Fats Have On My Cholesterol?

Fats carry a lot of cholesterol.  Limit unsaturated fats but continue to consume saturated and trans fat at monitored levels.  Cholesterol is important to the body at appropriate levels.
