What is cholesterol?Cholesterol is a waxy, fat-like substance that's found in all the cells in your body. Your liver makes cholesterol, and it is also in some foods, such as meat and dairy products. Your body needs some cholesterol to work properly. But having too much cholesterol in your blood raises your risk of coronary artery disease.
What is VLDL cholesterol?VLDL stands for very-low-density lipoprotein. Your liver makes VLDL cholesterol and releases it into your bloodstream. The VLDL particles carry triglycerides, another type of fat, to your tissues. VLDL is similar to LDL cholesterol, but LDL carries cholesterol to your tissues instead of triglycerides.
VLDL and LDL are "bad" cholesterols because they can contribute to the buildup of plaque in your arteries. This buildup is called atherosclerosis. The plaque that builds up is a sticky substance made up of fat, cholesterol, calcium, and other substances found in the blood. Over time, the plaque hardens and narrows your arteries. This limits the flow of oxygen-rich blood to your body. It can lead to coronary artery disease and other heart diseases.
