A simple cholesterol definition
Cholesterol is a waxy, fat-like substance that occurs naturally in the body. It plays a vital role in how every cell works – but having too much cholesterol in the blood is one of the risk factors in the development of coronary heart disease. There are many risk factors for coronary heart disease, and it is important to take care of all of them to reduce the overall risk of it.
Cholesterol makes its way around the body in molecules called lipoproteins. There are two kinds that are particularly important, especially when we consider why one kind of cholesterol might be good, and another bad: LDL-cholesterol and HDL-cholesterol.
LDL (Low Density Lipoprotein)-cholesterol, is often called “bad cholesterol”, since it contains a relatively high amount of cholesterol that can build up in the arterial walls. However, HDL (High Density Lipoprotein)-cholesterol is able to remove and carry cholesterol from the arteries and take it to the liver, where it is eliminated – which is why it is often called “good cholesterol”.

What is cholesterol used for?
Your body produces cholesterol because we need it to carry out a number of different functions – it’s an important component of cell membranes and a precursor of hormones and bile acids, which aid digestion.
What is a cholesterol level?
Your cholesterol level is determined via a blood test, and can be performed by your GP or pharmacist. The results indicate not only the quantity, but also the kind of cholesterol in your blood. While you should be keeping your overall total cholesterol down, the ratio of HDL to total cholesterol is also important, as HDL-cholesterol performs a different function to LDL-cholesterol.
