Norm of cholesterol in women after 50 years
Cholesterol, or fatty alcohol is a natural lipophilic compound that is an essential component of all living things. In the recent past, its value for a person unjustly downplay. However, after some time has been confirmed the exceptional need this compound for the stable functioning of the body.
Norm of cholesterol in women by age
The concentration of fatty alcohol in women is approximately the same values until the onset of menopause. When explaining the results of the analysis on the contents of lipids (fats) in the blood plasma, the physician should consider a number of additional factors that can skew the real picture. Pregnancy, thyroid dysfunction, and other conditions provoke a change in the average concentration of organic compounds. Norm of cholesterol in blood of women is reflected in the following table:
|Age, years|| Total cholesterol,
|Less dense PL, mmol/l||High-density LP, mmol/l|
|40-45||Of 6.52||Of 4.52||2,27|
A significant part of the lipophilic compounds produced by the liver. Only 20% of its share comes along with the food. Lipids of blood plasma are transported in the form of low density (LDL) and high density (HDL) poliproteinov, the total value of which determines the concentration of total cholesterol. The excess of the first substance affects the metabolism, provokes the development of pathological blood vessels and internal organs. The normal total cholesterol in women after age 50 is supported by the following simple rules:
- not to eat fried foods,
- increase physical activity;
- to reduce the consumption of salt;
- to reduce excess weight;
- to include in the diet plenty of fruits and vegetables;
- to follow a low-protein diet.
Low density lipoproteins
The fraction of LDL in the overall structure of lipophilic compounds is about 70%. Excessive amounts of this substance leads to oxidative processes inside vessels and arteries, which causes the formation of atherosclerotic plaques. Low density lipoproteins are not absolutely harmful compounds. They participate in the delivery of cholesterol to all the cells of the body. It should be noted that atherogenic (promoting atherosclerosis) properties low density lipoproteins are effective only when their excessive accumulation in the blood serum.
HDL are produced solely by the body and do not cause the formation of atherosclerotic deposits. If there are not enough high-density lipoproteins impaired cellular membranes, inhibiting the formation of new structural elements. Good lipoprotein cleans the vascular wall from atherogenic concentrations of elements, preventing the risk of developing diseases of the heart and blood vessels.
Norm of triglycerides
Organic compounds, saturated esters of glycerol, represent a cholesterol lipids. Triglycerides (TG) are called fats of vegetable and animal origin. Recent scientific studies have confirmed the ability of these lipids to settle on the endothelium (the inner cells) of blood vessels, causing their blockage. For this reason, it is very important to control the intake of unsaturated fats along with food. The norm of TG in the blood of women after 50 years is 2.95 mmol/L.
Changes in the level of cholesterol
Fluctuations in the concentration of fatty alcohol can happen for many reasons. Pathological change in the level is often associated with the development of serious diseases. The cholesterol test along with other laboratory tests to diagnose growth or reducing the concentration of LDL and HDL in the serum. High values of total liquid alcohol – not a reason for concern. The alarm signal can be considered to increase the level of low density lipoproteins and triglycerides. Norm of cholesterol in women after 50 years could change under the influence of:
- Seasons. The autumn-winter period is characterized by fluctuations of the concentration average values up to 2-4%.
- Period of the menstrual cycle. During the first half of the deviations can reach 10%.
- Pregnancy. High cholesterol in the blood of women with child bearing is quite a natural phenomenon. Normal change is the increase in the content of fat-containing alcohol up to 15%.
- A variety of diseases. Hypertension, angina, acute respiratory infections may provoke an excessive accumulation of blood lipids.
- Oncology. The tumor consumes a lot of nutrients, so the growth of malignant tumors can significantly reduce the levels of fatty compounds.
Low density cholesterol in normal conditions «chosen» molecules of HDL and does not clog blood vessels and arteries. If the same number of low density lipoprotein rapidly increases, it increases the risk of formation of atherosclerotic plaques. Such formations constrict the lumen of blood vessels, impeding the flow of oxygen-rich blood to the heart and brain. It contributes to the development of coronary artery disease, atherosclerosis of the lower limbs, stroke. The reasons for the increase of LDL following:
- irrational nutrition;
- sedentary lifestyle;
- bad habits;
- thyroid dysfunction;
- kidney failure;
- violations in the work of the pancreas;
Cholesterol below normal in women
The lack of fatty alcohol in humans may cause the development of many serious diseases. Blood lipids actively participate in all metabolic processes and their low level leads to degenerative changes of organs and systems. Hypocholesterolemia is especially dangerous for the older generation. People after 50 years of insufficient synthesis of LDL and HDL can lead to permanent mental disorder and the development of dementia. Hypocholesterolemia manifests itself:
- muscle weakness;
- lack of appetite;
- the steatorrhea («fatty» stools);
- aggressive-depressive syndrome;
- hyporeflexia (decreased reflexes);
- the decline of sexual activity.

 In Russia the level of cholesterol is measured in mol/l, and in the US it is calculated in mg/DL.
