Causing increased cholesterol?
It is known that in the overwhelming number of cases increasing this substance causes its deposition in the form of atheromatous plaques on the walls of blood vessels, thereby reducing their clearance. As a result, increases blood flow, which can tear the plaque that has become unstable and clog a vessel of smaller caliber. In the end, all the organs and tissues supplied with oxygen and nutrients below the blockage, experiencing hypoxia, and may die. So develop myocardial infarction and ischemic stroke. Causing increased cholesterol?
The value in the body
You need to know that cholesterol is not the ballast and the more harmful substance to the human body. The cholesterol is very important for life because it is the precursor of hormones in their synthesis, it makes many of the components of cell membranes, which stabilizes it, being fat-soluble. Such is the force of habit that «cholesterol» is a compound called incorrectly: it should be called the «cholesterol», since chemically it is a fat soluble alcohol.
Without cholesterol, it would be impossible the formation of bile, and consequently digestion. It is produced in the body in much higher quantities than comes from food: three-quarters of it is synthesized, and only one quarter comes from outside with food. Since cholesterol is «bound» to so many biological processes, has several sources of externally and «own production», it can accumulate in the body in excess. A specific depot had not, and it continues to circulate in the blood, and increase cholesterol in the blood causes blockage of blood vessels.
Regulations on the content of substances in the blood
If observed natural balance between the flow of cholesterol and its consumption on the needs of the body, the person is low risk of heart attacks and strokes, and as men and women ranging up to 5.2 mmol/l normal total cholesterol ranges from 2.9 to 5.2 for small children under the age of 5 years and throughout life is growing steadily. For the elderly over 70 years the norm will be a range of values from 4.5 to 7.2 (for women) and to 6.8 mmol/l in men.
Hypertension no longer a death sentence?
The cardiologist said that there is finally a cure for hypertension …
From what elevated levels of cholesterol in women? This is because male sex hormones and their effects lead to an overall decrease in fat tissue in the body for men (compared to women), but the inside cholesterolemic fractions ratio may change. So when the doctor interpreterpath the results, he must necessarily take into account the patient’s age and gender.
It is the concentration of total cholesterol in blood plasma, which consists of two unequal parts: the majority is LDL (low density lipoprotein, or «bad» part), the smaller part is harmless cholesterol, which is transported in the blood in the form of high-density lipoproteins. The ratio of «bad» and «good» cholesterol for age 40 following:
- «bad LDL»: 2.2 and 4.8 for men and 1.9 to 4.5 for women;
- «good HDL» is 0.7 and 1.7 for men and 0.8 – 2,12 for women.
For clarity, introduced the «atherogenic coefficient», which shows the ratio of «bad» and «good» faction. Ideally, he must strive for three: these figures occur in people 30 years of age with no signs of atherosclerosis in normal numbers, the amount of cholesterol. To calculate it easily yourself: for this you need the number of total cholesterol to take away the «good» (HDL) and the difference is again divided by HDL.
The reasons for the increase
High cholesterol depends on many factors – both external and internal. Also the reasons for the increase can lie in of various diseases, and the genetic characteristics transmitted by inheritance. Among them, worth noting:
- hereditary (familial) Hyper – and dyslipoproteinemia;
- liver disease accompanied by cholestasis (disruption of bile flow);
- renal disease: glomerulonephritis, renal failure and nephrotic syndrome;
- malignant neoplasms of the pancreas, in men – prostate;
- the reduced activity of the thyroid gland (hypothyroidism);
- gout, high cholesterol happens when hyperuricemia (elevated concentrations of uric acid in the blood);
- diabetes mellitus;
- alcoholism – alas, this is a very common cause of high content of cholesterol.
All other reasons are external:
- quick weight loss fat people;
- cholesterol-rich foods;
- the medication, which in its structure similar to cholesterol or can transform (hormones, Cyclosporine, vitamin D).
In addition, diuretics may cause «false positive increase» values. Why? Yes, because they can cause «thickening» of cholesterol per unit volume of blood plasma, so it must be taken into account before testing.
«I did not believe that hypertension can be defeated!»
Hypertensive veteran Oleg Tabakov has shared the secret of his recovery.
Cholesterol and food
Despite the fact that 80% of cholesterol produced in the body, gipoholesterinova diets are an important subject for public discussion. The thing is that gipoholesterinova diet protects against many other problems, bringing the body, as it incorporates a moderate consumption of wholesome food. It helps to reduce weight, reduce joint stress, increase physical activity, reduce the amount of salt and water in the body, and, as a result, lead to improvement in health. This will be the best treatment of hypercholesterolaemia and primary prevention of severe complications. Foods rich in cholesterol:
- fatty pork, bacon;
- offal: offal, liver, kidney;
- melted butter (animal) oil;
- the yolk of a chicken egg.
The list is long, but the important thing to remember is that the main role in case of critical situation and increase the risk of harmful playing habits, physical inactivity and stress. Even very elderly people with high cholesterol, living a moderate and orderly life, the risk of sudden catastrophe may be lower than that of young fat man, who spends all night at the computer with a beer and pack of cigarettes.
