Cholesterolemia is the content of cholesterol in the blood. Total cholesterol blood (norm 150 to 250 mg%) consists of free and efitnessnow cholesterol (OK 65-75% of total cholesterol).
The increase in total cholesterol in the blood - cholesterol - occurs when mechanical jaundice, cholangitis, lipoid principally, atherosclerosis, miksedeme, diabetes and other metabolic diseases.
The decrease in total cholesterol in the blood - hypocholesterolemia is observed in thyrotoxicosis, edisonova illness, eating disorders, colitis. The decrease efitnessnow of cholesterol in the blood is typical for the human liver.
The amount of total cholesterol determined by the intensity of green in color, formed by the action of serum acetic anhydride and sulfuric acid.

Cholesterolemia - cholesterol in the blood. (The term "cholesterolemia" is sometimes used in the sense of "high cholesterol".) The human body contains cholesterol exogenous (alimentary) and endogenous (synthesized in the body).
Blood cholesterol is as a mandatory part in the free state and in the form of the cholesterol-esters. In healthy people, the content of cholesterol in the blood varies from 150 to 250 mg%. In persons asthenic physique, it is lower in individuals gipertonicescomu - up. The content of cholesterol in the blood, a lot depends on diet, as growth proceeds of cholesterol from food to some extent inhibits biosynthesis of endogenous cholesterol and a decrease of dietary cholesterol increases its formation in the body. On the cholesterol level in the blood is influenced by the nervous and endocrine systems. Upon excitation of higher nervous system, the content of cholesterol in the blood increases with decreasing anxiety, braking decreases. The liver is involved in the regulation of cholesterol level in blood, partly because it highlights the cholesterol from the body with jelchew and participates in the endogenous formation of cholesterol.
Cholesterol - high content of cholesterol in the blood occurs during pregnancy and premenstrual period when air anaesthesia, in some diseases, metabolism (diabetes, obesity, gout, xanthomatose), sometimes with atherosclerosis, when downgrading of the thyroid gland, with biliary cirrhosis of the liver, mechanical jaundice, jelchnokamennaya disease, nephrotic syndrome, after acute and severe bleeding.
Hypocholesterolemia - low content of cholesterol in the blood is observed when hemolytic anemia and anemia Addison - Biermer, acute and chronic hepatitis, thyrotoxicosis, when obstruction of the urinary tract and sometimes in the terminal phase of glomerulonephritis, with high intestinal obstruction, sometimes at a tuberculosis of lungs, acute pancreatitis.
