What Is a High Cholesterol Rating?

Cholesterol is a soft, waxy substance that is found in the bloodstream. Cholesterol has many positive uses in the body, such as strengthening cellular walls. However, too much cholesterol can lead to heart disease and death.

  1. About

    • Molecules of cholesterol are transported through the bloodstream by carrier molecules called lipoproteins. There are two types of cholesterol carriers: high-density lipoproteins, or HDL, and low-density lipoproteins, or LDL.

    Types

    • LDL is commonly referred to as "bad cholesterol" because it builds up on the arterial walls and can block the flow of blood to and from the heart. HDL is commonly referred to as "good cholesterol" because it removes HDL from the blood and takes it to the liver to be metabolized.

    LDL in Depth

    • High levels of LDL cholesterol are associated with an increased risk of heart disease and death, according to the American Heart Association. LDL cholesterol levels should be lower than 160mg per deciliter, or dL, of blood in healthy persons, and lower than 100mg/dL of blood in persons at risk for heart disease.

    HDL in Depth

    • Higher levels of HDL cholesterol provide protection from the negative effects of LDL and are associated with reduced risk of heart disease. HDL levels should be no less than 40mg/dL, and ideally higher than 60mg/dL.

    Considerations

    • The American Heart Association has established acceptable levels of total blood cholesterol for healthy persons. Normal total blood cholesterol is 200mg/dL or lower. A measurement of 240mg/dL and higher is considered high cholesterol.

    Prevention/Solution

    • To reduce the risk of high cholesterol, eat a diet that is low in saturated fats, but high in fruits and vegetables. Avoid tobacco products and excessive alcohol consumption, and exercise regularly.
