What is cholesterol, and does it matter?

A routine blood test can reveal a blood cholesterol that is too high even if the individual is mostly in good shape, and is without pain.

However, hygienodietetiques rules should be applied in order to minimise any risk of cardiovascular incident.

What is the role of cholesterol?

This molecule composed of 27 carbon atoms is one of the elements, which form the membranes of our cells. Indeed, it fits between certain molecules ensuring membrane permeability of the cell and exchanges outwards.

Cholesterol also allows the development of hormones (especially sex hormones).
His latest role is to facilitate digestion because it is processed by the liver bile acids.

What are the consequences of excessive cholesterol?

The risk of cardiovascular disease increases in proportion to the increase in blood cholesterol.

When fats circulating in too large quantities in the blood, they are deposited on the walls of arteries and ultimately develop deposits of fat. The plates of fat will begin to thicken gradually the bloodstream.

What are the symptoms?

Only the blood test can detect an excess of cholesterol. However, if no action is taken in cases of coronary problems, chest pain may occur after several years: the pain of angina.

The blood circulating evil, the heart is deprived of oxygen, which causes pain first effort and then pain at rest.

How to detect cholesterol?
Cholesterol is largely manufactured by the body, only one third comes from food.

What are LADLE and HAL?

The cholesterol, belonging to the family of fats, is totally insoluble in the blood. He therefore needs to move carriers: these lipoproteins. The latter are classified according to their density:

— HAL (high density lipoprotein) with a protective role because it contributes to the elimination of cholesterol. It is better known as the “good cholesterol”.

— LDL (low density lipoprotein) or “bad cholesterol” is deposited on the walls of arteries and can lead to atherosclerosis.

How to decipher the blood test?

An increase in LDL and a decrease in HDL are related to a significant risk of cardiovascular disease.
Below are the values of desirable fats in the blood:

— Total cholesterol <2 g / l
— LDL <1.3 g / l — HDL (male)> 0.45 g / l
— HDL (Female)> 0.55 g / l

To fight against excessive cholesterol, dietary measures will be applied first and then, if they prove insufficient after 2 months, drug treatment will be prescribed.
