Defining and understanding cholesterol metabolism requires some background knowledge of anatomical processes. The causes, effects, and possible ways to solve the problems should also be discussed. What do we understand by cholesterol? Medical dictionaries explain that this fat normally found in blood, results from eating animal-based foods. This substance is processed by the liver and it is an essential building block for healthy cells and nerves while it also serves to producing some hormones. However, the growth of the cholesterol level above the normal level presents high health risks for the heart and the circulatory system. 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 get into more detail, you should be aware of the two types of metabolism that exist: building up – anabolism, and breaking down – catabolism. With anabolism, small molecules create large ones, amino acids turn into protein. Obviously the reversed process takes place in catabolism, 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 body. There is a higher serum cholesterol level when the ingested quantity is higher than the body’s need and ability to process. Besides the liver, the ability to synthesize cholesterol is specific to all the body tissues. The more cholesterol is taken in, the less it gets synthesized 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, genetic factors, improper diet, a sedentary lifestyle, and, as a result, weight gain, all together become an extreme drawback for cholesterol metabolism. In the condition of a faulty cholesterol metabolism, hypothyroidism, diabetes and hypertension can develop or aggravate. In some cases it is simply the liver which cannot accomplish its tasks. If you have a family history of high cholesterol, keep an eye on your health. Unfortunately for those who are predisposed genetically to elevated cholesterol levels, even the toughest low-fat or no-fat diets are of no much use. Medication can surely help. Dieting and developing a physical training routine are also good but they are often insufficient.
