High-density lipoprotein (HDL) is the “good,” healthy kind of cholesterol. It transports excess cholesterol out of your arteries to your liver, which removes it from your body. Cholesterol itself isn’t bad. Your body needs some cholesterol to make hormones, vitamin D, and digestive fluids.
Low-density lipoprotein (LDL) carries cholesterol from your liver to the cells around your body where it’s needed. But if the level of LDL in your blood is too high, it can form fatty deposits in your arteries. This increases your risk of heart disease and stroke.
Triglycerides are a type of fat found in your blood. .But high triglycerides might raise your risk of heart disease and may be a sign of metabolic syndrome. Metabolic syndrome is the combination of high blood pressure, high blood sugar, too much fat around the waist, low HDL (“good”) cholesterol, and high triglycerides.
