Why is HDL Cholesterol Good?

 


Cholesterol is needed by the body

Cholesterol is a waxy, fatty substance in the blood that plays an important role in the body’s cells and hormonesMake no mistake; cholesterol is of the utmost importance to the body. The liver produces all the cholesterol the body needs. As it is, unfortunately the liver is also enticed to produce more cholesterol than is actually necessary for the body. This process is triggered by the fat in the food we eat - saturated fat in meat and dairy products.

High cholesterol is one of the major risk factors for heart disease. The reason is because excess amounts of cholesterol are deposited on the inside of arteries. If the blood cholesterol level continues to be high, more fatty material is deposited, narrowing the arteries even more, resulting restricted blood flow to the heart and other areas of the body. The restricted blood flow encourages formation of a blood clot, which may cause the final blockage. If the blood flow is blocked off completely, it can result in a heart attack or stroke.

The good news is that cholesterol in a way also carries “cleaners” as part of its composition. These “cleaners” are actually HDL cholesterol - HDL stands for High Density Lipoprotein. Lipoproteins, which are combinations of fats and proteins, are the form in which fat are transported in the blood. The high-density lipoproteins transport cholesterol from the tissues of the body to the liver where it is passed from the body. HDL cholesterol is therefore considered the "good" cholesterol. The higher the HDL cholesterol level, the lower the risk of coronary artery disease.

Even small increases in HDL cholesterol reduce the frequency of heart attacks. On the flip side of the coin, the lower the HDL level, the higher the risk for heart disease. Any person’s priority should therefore be to ensure their HDL cholesterol levels are constantly high to ensure maximum protection. The first step is to modify one’s lifestyle. Regular exercise, loss of excess weight and quitting of smoking will increase HDL cholesterol levels. Moderate alcohol consumption (such as one drink a day) also raises HDL cholesterol. When life style modifications are insufficient, medications are used. Medications that are effective in increasing HDL cholesterol include nicotinic acid (niacin), gemfibrozil, estrogen, and to a lesser extent, the Statin drugs.

So remember who the good guys in your blood are and look after them – they are looking after you and your heart!
