ABOUT CHOLESTEROL
What is cholesterol?
It is an important component of metabolism. It "floats" in the blood is taken up by cells and is localized mainly in cell membranes. A man "contains" about 150 g cholesterol. Vital substance, it is used by the body as a building material in the production of acids, hormones and vitamin D.
The risk of high cholesterol
Cholesterol can penetrate the walls of the arteries, which over time form the storehouse. So arise so-called "Particle" fat (atheroma) that can break suddenly and can clog arteries. That's what makes it dangerous risk present in excess cholesterol. The consequences can be fatal: myocardial infarction, stroke, acute disorders of blood circulation in the legs. Abrupt closure of the coronary arteries can lead to heart death.
Frequently, blood vessels, cholesterol change because they and limescale, which leads to sclerosis of vessels (arteriosclerosis). Smoking, hypertension and diabetes worsens this process and increase the risk of complications in the functioning of blood vessels.

"Good" cholesterol and "bad" cholesterol
Total blood cholesterol consists of LDL cholesterol and HDL cholesterol.
The high values of LDL are considered "bad", because LDL is deposited in the arteries and lead to atherosclerosis. The high values of HDL are considered instead, as "good" because HDL combat limescale on vessel walls. When the total cholesterol above 200 mg / dl, the doctor is obliged to separately measure LDL's and HDL's to more accurately assess the risk of arteriosclerosis installation. LDL cholesterol greater than 160 mg / dl is considered high, while that of more than 190 mg / dl, as dangerous. HDL's are considered too low when falls below 40 mg / dl.
What values are normal?
In principle, a total of 200 mg / dl cholesterol is considered to be normal. The risk of progression to atherosclerosis is, in this case reduced. Preventive cholesterol levels should be measured every year. Blood for analysis is taken on an empty stomach, which means not to be eaten, 5 hours before, and not be drinking liquid calories.
Normal values
When should we treat?
When there is no evidence of the existence of venous disease, high cholesterol may remain untreated with medication. What's not true if there is a disease of the veins, such as narrowing of the coronary or carotid artery, or when there are other risk factors, such as smoking, hypertension, diabetes, family tensions. In their absence, values around 200 mg / dl does not require harsh drug treatments. But there is a risk that health to worsen, for ten years at a rate of 20-40% is recommended drug therapy. Very good is naturist treatment, but in severe cases, is more lasting than drug therapy. In principle, experts estimate that almost always about 20-40% of those who get in excess of cholesterol shows for 10 years suffering severe blood vessels. A risk that gives back significantly if your cholesterol drops by about a quarter.
