Guide To The Different Types Of Cholesterol

Cholesterol, a soft, wax-like substance, is found in every cell in the body, and it plays a role in the construction of cell membranes. The liver manufactures sufficient cholesterol for the body's needs, and some foods contain cholesterol too. Lipoproteins are the vehicles that transport cholesterol around the body. These proteins form a protective casing for the cholesterol so it will not separate from the blood. While some cholesterol is necessary, excessive amounts are associated with an increased risk for cardiovascular disease and strokes. For this reason, patients who are twenty years old and older are advised to have a blood test to measure their cholesterol at least once every four to six years. Ideally, total cholesterol readings should be below 200mg/dL, and some health organizations recommend that total cholesterol be no higher than 185mg/dL. Total cholesterol measurements above 240mg/dL are considered high.
