Cholesterol and triglycerides are fatty substances that can be found in the blood. There are 2 types of cholesterol:

(1) Low Density Lipoprotein (LDL) cholesterol which is sometimes referred to as BAD cholesterol because it increases your risk of coronary heart disease
(2) High Density Lipoprotein (HDL) cholesterol, which is the GOOD cholesterol because it protects you against coronary heart disease

Triglycerides travel through your blood and are also stored as fat deposits in your body. High levels of triglycerides are common in people with high cholesterol, and in people who are overweight and have heart disease and/or diabetes.

LDL cholesterol accumulates along your artery walls, forming plaque and narrowing your arteries. HDL cholesterol then comes along and tries to clean it up.

So usually when you get a blood test the doctors will check both your total cholesterol and your HDL cholesterol levels and then sometimes they will calculate a ratio by dividing the total cholesterol by the HDL cholesterol. The lower this ratio…the better off you are when it comes to heart disease. Read more
