Cholesterol is present in the blood in two forms, good form and bad form. The good form is the high density lipoprotein (HDL) and the bad form is the low density lipoprotein (LDL). The LDL is called the bad cholesterol because it tends to stick to the wall of the arteries causing narrowing of the blood passage and thickening of the artery wall. There are several complications that may occur with the accumulation of LDL on the walls of the arteries and we are going to discuss some of them below.
The first thing that may occur is the atherosclerosis which means the lack of elasticity of the arteries and development of stiffness in several parts of the artery wall. This means that the artery is no more able to contract and pump blood forward. Thickening of the wall will decrease the lumen so the oxygenated blood flow will be reduced and the heart and body organs will receive fewer amounts of nutrients and oxygen, in the heart this means the development of angina.
The accumulation of oxidized LDL on the walls may lead to detachment of shuts of LDL these shunts or more known as emboli will circulate in blood and lodge in any place causing a thrombus. The thrombus will cut the supply of nutrients from the destination organ. If the destination organ is heart then a heart attack will occur while if the location is near to the brain then it may lead to stroke.
These complications could increase exponentially in the presence of other predisposing factors. The first risk factor is the obesity, being overweight is very risky because more fat means more accumulation of LDL in your body. If you are obese then you may need to follow a diet plan to decrease that extra weight and extra risk factor.
