There are two types of cholesterol: good and bad. Too much of one type or not enough of another can put you at risk for coronary heart disease, heart attack, or stroke. A simple blood test can measure levels of both good and bad cholesterol.
- "Good" Cholesterol - High-density lipoproteins (HDL) absorbs bad cholesterol and carries it back to the liver to remove it from the body. High levels of HDL reduce the risk of heart disease and stroke.
- "Bad" Cholesterol - Low-density lipoproteins (LDL) makes up the majority of the body's cholesterol. High levels of LDL can build up in the arteries and result in heart disease.
Most high cholesterol is due to health behaviors that people can change, such aas eating a lot of unhealthy food or not exercising.
What you should do to maintain healthy cholesterol levels
