Lipemia is the content of fatty substances (lipids) in the blood, hyperlipemia - increased their content. Normal plasma contains 0,4-0,7% lipids. When their number exceeds 1 %, plasma and serum become cloudy, milky appearance, and whole blood and chocolate tint. Physiological hyperlipemia occurs after eating, especially after the fat-rich food (8-10 hours), and pregnancy. Pathological hyperlipemia is celebrated in some diseases of the liver and kidneys, diabetes, anemia, starvation, hypothyroidism, and in case of poisoning chloroform, alcohol, phosphorus.

Lipemia (from the Greek. lipos - fat and haima, blood; a synonym of the world) - the high content of fat in the blood. In a healthy organism on an empty stomach all of lipids in the blood plasma contains about 600 mg%. Blood lipids is a complex mixture of phospholipids (200 mg%), cholesterol and its esters (190 mg%), neutral fats (150 mg%) and free fatty acids (60 mg%). Under physiological conditions lipemia occurs within 3-4 hours after eating food rich in fats; reaches its maximum after 6 hours, after which the fat content is returned to the original level.
Lipemia observed in the changes of the functional body state (pregnancy, starvation); may be the result of slow removal of lipids from the bloodstream, violations of normal speed of synthesis and decomposition. Lipemia is also in different pathological States of organism - in diabetes, obstructive jaundice, principally, pancreatitis, hypothyreosis, xanthomatose and atherosclerosis; when bloodletting and bleeding, severe anemia, caused by poisoning various substances (benzene, chloroform, pyridine, phenylhydrazine, phosphorus), chronic alcoholism.
When expressed lipemia blood plasma becomes milky white muddy color. In the case of food lipemia introduction of heparin leads to enlightenment plasma. In the blood plasma of healthy organism is observed constancy of relations between different lipids. When L. there is a growth of all the above lipid fractions. However, a number of pathological States of organism is characterized by a shift in their relationships. In atherosclerosis and diabetes installed shift in the ratio of cholesterol/phospholipids
Lipemia develops as a result of excessive consumption of food rich in fats. This lipemia characterized by high content of chylomicrons - coarse emulsion - lipids. Neutral fats and other lipids circulate in the blood mainly in the form of complex compounds, mainly of proteins called lipoproteins (see). In the result of transformation of chylomicrons occur high-density lipoprotein.
