Too much LDL can make cholesterol build up in your arteries, making them narrow and stiff, or blocking them, which makes it more difficult for blood to flow. Low-density lipoprotein (LDL): LDL, often called "bad" cholesterol, transports cholesterol throughout your body to the cells that need it. The cholesterol is bound to low-density lipoprotein (LDL) and high-density lipoprotein (HDL) as it moves through the blood. Total Cholesterol: This measures the total amount of cholesterol found in your blood. HDL and LDL are 2 types of lipoproteins that bind to cholesterol and carry it throughout the body. High levels of triglycerides in your body can lead to weight gain, diabetes, and heart disease.Ĭholesterol and triglycerides are lipids (fats) that are transported through the blood by lipoproteins, a combination of lipids and protein. Triglycerides are used by your body to store energy in the form of fat until your body needs it. LDL is often called “bad cholesterol” because it can cause the buildup of fatty deposits (plaques) in your arteries (atherosclerosis), which reduces blood flow, increasing the risk for heart attack or heart disease. HDL, often called “good cholesterol,” helps remove bad cholesterol from the body. Some important cholesterol numbers are total cholesterol, HDL, LDL, and triglycerides. It can help determine the risk of fatty buildup on the artery walls and the risk of heart disease. This test measures the levels of cholesterol and lipids circulating in the blood.

This can increase your risk of heart disease, stroke, and other serious health conditions. Too much cholesterol in the blood can clog blood vessels, reducing the flow of blood to the heart, brain, and other organs. Cholesterol comes from some animal-based foods, such as eggs, meat, and dairy. Cholesterol is a waxy, fatty substance found in everyone’s blood and is needed to make cell membranes, some hormones, and Vitamin D.
