Blood tests: Cholestero

Cholesterol is a sterol present in the human body, sterols are a type of natural fat that is found in all tissues of the body and is part of cell membranes, bile acids, steroid hormones and lipoproteins. The main consequence that causes cholesterol when it is in excess is the accumulation of fats in the vital arteries, bringing as a consequence multiple ailments such as atherosclerosis, stroke, as well as peripheral vascular disease.

Cholesterol in the optimal state represents a major contributor to gallstones. The main cause for atheroma formation is the accumulation of cholesterol in the arterial pathways. Atheromas are a type of lesion typical of atherosclerosis, and vascular diseases including acute myocardial infarction. For this reason it is essential to maintain the optimal levels of cholesterol in the body.

Cholesterol comes from two sources, an external source that is included inside the foods we consume and another internal source that is the one that produces our own organism, for this reason you can present cases of people who lead a healthy diet, without the intake excessive fat that could be converted to cholesterol and present high levels of cholesterol in your bloodstream, this could be the result of some genetic metabolic disorder that produces such elevation. Animal foods such as meat, eggs and dairy are high in cholesterol, the body absorbs about half of the cholesterol contained in foods of animal origin, while sterols in vegetables are poorly absorbed by the body. Although the main source of cholesterol comes from the diet, the main internal producer of this type of fat is the liver, other organs such as the intestine, testicles or ovaries and the adrenal cortex are other organs that also produce cholesterol in less proportion.

Blood Cholesterol Levels Blood tests measure the levels of the types of cholesterol present in the body, which tell us if cholesterol is at its optimal level, whether it is low or high. Total cholesterol Total cholesterol is a very common value in blood tests involving a sum of the types of cholesterols present in the blood, which indicates: The best: when the total cholesterol level is less than 200.

High Intermediate: when the level of toral cholesterol is between 200 to 239. High: when the total cholesterol level is higher than 240. When the total cholesterol level is above 240, it is very common for the specialist to request an assessment of the levels of LDL and HDL cholesterol types separately before starting any treatment. LDL cholesterol Usually LDL cholesterol is known as bad cholesterol, and corresponds to low density lipoprotein. This is a particle composed of protein and fat whose function is to transport cholesterol, triglycerides and lipids through the blood throughout the body. This type of cholesterol when being in excess could clog the arteries. LDL cholesterol is cholesterol that should be treated with greater caution and is the one that doctors usually check more often. This cholesterol is related to cardiovascular disease, being too high the patient will need treatment with urgency. The optimal level of LDL cholesterol in the body is less than 100 mg / dL, when a person has a history of heart disease it is recommended to keep cholesterol levels below 70 mg / dL. Values ​​close to the optimum level: from 100 to 129 mg / dL. High intermediate values: 130 to 159 mg / dL. High values: 160 to 189 mg / dL. Values ​​very high: 190 mg / dL and higher than this. HDL cholesterol HDL cholesterol is also known as good cholesterol. This is a high density lipoprotein, responsible for transporting different types of fats such as cholesterol, triglycerides and lipids throughout the body through the bloodstream to the liver. It is recommended to keep cholesterol levels as high as possible, the higher the levels in both male and female patients, the lower the risk of coronary artery disease. Healthy HDL levels should be like the following: Men above 40 mg / dL. Women above 50 mg / dL. Physical exercise helps increase HDL cholesterol levels.
