Cholesterol, although an essential substance for our body, can be harmful if present in excess amounts. When cholesterol gets deposited in the treaties, it leads to blockage and formation of plaques. This condition is known as atherosclerosis. It can sometimes lead to block in the arteries and hence narrowing of blood vessels. This means that the heart will not get its due share of oxygen and nutrients. When this condition grows worse, it leads to coronary artery disease, also called CAD. If this is left untreated, it can lead to a heart attack or myocardial ischemia. Therefore, one should be very careful of the dietary intake of cholesterol and have a good and healthy lifestyle.
One should be very careful of the kind of cholesterol that you take in through your diet. The two types of cholesterol are low density lipoprotein cholesterol or LDL cholesterol and high density lipoprotein cholesterol or HDL cholesterol. Generally, if the body contains lesser amounts of LDL cholesterol and higher amounts of HDL cholesterol it is considered well for the heart.
When having a proper diet and exercising enough does not help, cholesterol medication is required. These medicines reduce the amount of low density lipoprotein cholesterol or LDL cholesterol, and also lead to a reduction in triglycerides which increases the risk of heart diseases and an increase in the high density lipoprotein cholesterol or HDL cholesterol. From time to time, the doctor may recommend taking liver tests to make sure that the medication is not having a negative effect on the liver.
