Total cholesterol includes LDL cholesterol
The good cholesterol: HDL cholesterol
HDL Lipoproteins recover the excess cholesterol settled in the arteries and transport it to the liver
where it is eliminated. HDL cholesterol removes poor quality lipid deposits from the arteries. This cholesterol associated with HDL is called "good cholesterol" : it reduces the risks of atheromatous plaques.
Approximately 20 to 30% of blood cholesterol is associated with HDL.
The bad cholesterol: LDL cholesterol
Lipoproteins, harmful to the body, deposit cholesterol on the walls of the arteries, which produce atheromatous plaques. This cholesterol tends to settle in the arteries and to block them. 60 to 80% of cholesterol in blood is associated with LDL.
A high level of LDL cholesterol
A high level of LDL-cholesterol leads to the formation of atheromatous plaques which narrows the arteries and can reduce the blood flow and in some case a blood clot can form over the plaque and cause a stroke
or heart attack.
High HDL (bad cholesterol) and low LDL (good cholesterol) are risk factors for;
- cardiovascular diseases (high blood pressure, heart attacks and poor circulation)
- cerebral vascular accidents (stokes and transient ischaemic attacks)
