It is a common misconception that all cholesterols are bad for you. Cholesterol is in fact an important part of a healthy body and it is perfectly normal to have some cholesterol in your bloodstream.
Cholesterol promotes the production of cell membranes and certain hormones. Although, too much of it can be a risk, which is why you must monitor your diet and lifestyle to avoid heart disease and stroke.
Cholesterol can not dissolve in your bloodstream. Instead it is transported to and from the cells by lipoproteins and a low density of these lipoproteins means that cholesterol can slowly build up in the artery walls forming plaque, leading to clotting and blocking of arteries. The very large particles are called Very Low Density Lipoproteins (VLDL), the intermediate size ones are called Low Density Lipoprotein (LDL) , which are the culprits causing heart disease. The smallest particles are called High Density Lipoproteins (HDL) which protect against heart disease.
A common condition resulting from high cholesterol is atherosclerosis, where the build up of plaque on artery walls can partially or completely block the blood flow to your heart and brain.
Regardless of your weight, daily activity levels and diet, you should have regular check ups to keep your cholesterol in check.
