Cholesterol is through the blood attached to proteins. This combination of protein and cholesterol are called lipoproteins. You might have heard a variety of cholesterol, which is based on the type of cholesterol, lipoproteins position. They are:
Low-density lipoprotein (LDL). LDL or "bad" cholesterol particles carry cholesterol throughout the body. LDL cholesterol accumulates in artery walls, making them hard and narrow.
Very-low-density lipoprotein (VLDL). This type contains the highest density lipoprotein triglycerides, fats, proteins attached to the blood. LDL cholesterol, VLDL cholesterol makes it bigger, which causes narrowing of blood vessels. If you take medication to lower cholesterol, but have a high VLDL level, you may need therapy to lower triglycerides.
High-density lipoprotein (HDL). HDL or "good" cholesterol picks up excess cholesterol and takes it back to the liver.
Factors in their control - such as inactivity, obesity and unhealthy diet - contribute to high levels of LDL-cholesterol and low HDL-cholesterol. Factors outside the control may also be important. For example, the genetic makeup may keep cells to remove LDL cholesterol from the blood efficiently or cause liver produces cholesterol too.
