The cholesterol is a substance absolutely vital because it is a component of the membrane of our cells. It is manufactured by our liver and provided by our diet. The cholesterol plays an important role in the functioning of the nervous system.Cholesterol is a natural fat essential to the body. It allows among others, the synthesis of vitamin D and bile. It is a constituent of the wall of our cells. Finally, it is a component of many hormones, such as sexual hormones.It is mainly produced by the liver (3 / 4) and the rest comes from food. It is found in products of animal origin at rates vary widely: meat, offal, dairy products, seafood, shellfish, fish, eggs ...
The cholesterol lipid is a sterol family that plays a central role in many biochemical processes.
Cholesterol is present in all cells. Its high rate can lead to gallstones or constitute a risk factor for atherosclerosis.
The word cholesterol means a molecule and should not be confused with the terms of good cholesterol and bad cholesterol referring to HDL and LDL, carriers of cholesterol in the blood.
There is obviously no two types of cholesterol. But cholesterol is transported in the blood transport systems with very different roles: lipoproteins LDL (small density lipoproteins) and HDL (high density lipoprotein).

The HDL cholesterol, in recovering the body has too much to bring it to the liver where it is eliminated. They have the power to clean our streets of all the fatty deposits of low quality and reduce the risk of seeing an atherosclerotic plaque. This is the good cholesterol.
The LDL deposit cholesterol on artery walls. He then formed gradually, real plates of fat, called atheroma. This is the bad cholesterol.
The dangers and health risks of cholesterol:
Epidemiological studies have shown that high cholesterol and lack of good cholesterol were risk factors for cardiovascular disease.
-Cholesterol is one of the causative agents of atherosclerosis leading to cardiovascular disease.
-Cholesterol, it is needed: it is a constituent of cell walls, it contributes to the production of hormones. But it is not too much.
When you have too much LDL cholesterol is deposited on the walls of arteries, including coronary, and fouls. Over the years, the diameter of these narrows, blood circulates more and more evil and clots are formed more easily. If one day, a clot is "stuck" in an artery of the heart and mouth, then the stroke.
Depending on your LDL and HDL following risks to your health may exist:
-Heart attack associated with atherosclerosis (obstruction by a mechanism of oxidation of the arteries).
-Stroke (stroke) related to atherosclerosis.
-Problems with clottingNote that doctors speak of cholesterol when your total cholesterol exceeds 6.5 mmol / L or your LDL (bad cholesterol) is greater than 4.5 mmol / L. This information is purely informative, ask your doctor for more information.
An accumulation of cholesterol risk:
When running in excess in the blood, cholesterol is dangerous for your heart, your brain and your legs. You increase your risk of having a heart attack or stroke.Too much cholesterol, it can have serious consequences for health.
In the vast majority of cases, cholesterol is totally devoid of symptoms until the onset of complications of atherosclerotic plaques (narrowing of the artery visible on ultrasound), stroke (or stroke) or cardiac (heart attack), arteritis of lower limbs ... As many disorders that can cause pain or significant disability or even be life threatening.
Monitor his plate:
To prevent the bad cholesterol, which significantly increases the cardiovascular risk, some medications are very effective. But nothing can replace the dietary indispensable at all stages of care.
