These two types of cholesterol are chemically the same. But in excess, it can lead to heart disease. Lipids are greasy organic compounds that circulate in the bloodstream. Lipoproteins are packages of proteins, cholesterol and triglycerides assembled by the liver. The plaque that is formed when the residue combines with oxygen causes the arterial blockages that lead to heart attacks.
Triglycerides are fats that circulate in the bloodstream along with cholesterol and other lipids.
Having your cholesterol level checked is as simple as getting a blood test. You should have your first cholesterol test at age 20, then get retested every five years, or more frequently if your total cholesterol is more than 200. Be sure to also have your HDL and LDL levels checked because these figures help indicate your risk of developing heart disease. The quick finger-stick tests done at shopping malls and other public places can yield inaccurate results. Poorly trained individuals may give the tests, and standard safety and sanitary procedures may not be followed.
