How to regulate cholesterol levels?
Over 40% of Canadians
aged 20 to 79 years and 36.5% of French people aged 18 to 79 would have a total
cholesterol detrimental to health. PasseportSanté tells you all about the
different ways to control his cholesterol.
Cholesterol:
reminders
Cholesterol is a lipid family sterol found in animal
products. The liver produces most of the cholesterol that the body needs to
function. The rest of the cholesterol "necessary" is provided by
food. Cholesterol is a constituent of cell membranes and the precursor of sex
hormones (progesterone, estrogen, testosterone), of billiaires salts and
vitamin D3.
Cholesterol is insoluble in blood. It is thanks to
lipoproteins that will be carried and transported throughout the body. There are
2 types of lipoproteins:
1. The
lipoprotein LDL (low density lipoprotein) associated with the
"bad " cholesterol
that deposit this excess cholesterol in the body on the walls of
arteries and causing, in the long term atherosclerosis that is to say, presence
of a plaque on the inner walls of arteries that may impede or block the flow of
blood.
2. The HDL
(high density lipoprotein) associated with the "good” cholesterol fetch
cholesterol deposited on artery walls by LDL lipoproteins and eliminate them.
It is lipoproteins that define the levels of
"good" and "bad" cholesterol in the blood. Cholesterol is
neither "good" nor "bad" in itself but its carriers
(lipoproteins) they are "good" or "bad".
How to detect high
cholesterol?
By a blood test will determine cholesterol levels (the
amount of LDL cholesterol, the amount of HDL cholesterol and total cholesterol)
and an analysis of these results.
Physicians assess cholesterol in relative terms this is -to
say analyzing these rates compared to the patient's general condition and the
presence of other factors such as personal history of cardiovascular disease,
age, smoking, diabetes, blood pressure, family history cardiovascular disease,
obesity and gender.
Doctors also analyze the total cholesterol / HDL cholesterol,
which shows the levels of "good" blood cholesterol compared to total
cholesterol. A low ratio is linked to a lower risk of disease.
For example, at equal cholesterol, a 60-year-old smoker with
a history of heart disease in his family will then be considered high risk that
a woman of 30 years with no risk factors will be considered low risk.
