In order to define cholesterol metabolism we ougth to explain several notions for a superior understanding. The causes, effects, and doable ways to solve the problems should also be discussed. First of all, what is cholesterol? Medical dictionaries explain that this fat normally found in blood, results from intake animal-based foods. The substance is metabolized in the liver and it has a role in the building of nerves, the generation of cells and the secretion of certain hormones. However, you should be careful about the growth of cholesterol levels, since high concentrations can lead to atherosclerosis and coronary artery disease (CAD), as well as heart attacks. Thus, in moderate amounts, this blood fat is necessary to the body.

Metabolism is the other concept that requires clarification for a full understanding of cholesterol metabolism. Metabolism is the sum of all chemical processes that take place in the body. To go a tiny bit further with the explanation, there are two types of metabolism: anabolism builds up while catabolism breaks down. With anabolism, small molecules create massive ones, amino acids turn into protein. Obviously catabolism involves the reversed process, larger molecules (for example glycogen) get broken down into smaller ones (like glucose).

Cholesterol metabolism is the sum of the anabolic and catabolic processes involved in synthesizing and degrading the cholesterol in the system. Serum cholesterol level increases when it is ingested and very swiftly absorbed. Besides the liver, the capability to synthesize cholesterol is specific to all the body tissues. The more cholesterol is taken in, the less it is processed by the body. The removal of cholesterol from the body is done by bile excretion after it is broken down in the liver.

High cholesterol is also caused by a sum of factors that increase the risks for one’s health. Thus, A sedentary life style, an improper diet, a genetic predisposition, topped by weight acquire turn into an extreme drawback for cholesterol metabolism. High blood pressure, diabetes, hypothyroidism and other health problems can also be a cause for high cholesterol levels. In some cases it is simply the liver which can't accomplish its tasks. If you have a family history of high cholesterol, watch your health more carefully. Unfortunately it is a lot more difficult to fight against genetic predisposition by simply sticking to diets. Medication can surely help. In other situations, a proper diet and a lot of physical activity can do much good.
