The permissible level of glucose in the blood: the norm in men of different ages. Explanation and table

For the normal functioning of organs, starting with the brain and human systems, including the processes occurring inside the cells of the body, glucose in the bloodstream is of great importance. To maintain good health it is very important to keep glucose in men at different ages.

The role of sugar in the body

In the case of a lack of glucose, which comes from the outside, the body of the individual processes its own fats. This procedure is accompanied by the release of ketone bodies, which can poison the body with a large accumulation. In the first place, brain cells suffer from this. If the glucose that comes during eating, does not have time to be processed by cells, then it is sent to the liver, where it is stored in the form of glycogen. As soon as there is a need, it will again be converted into carbohydrates and go to meet the needs of the body. Below is the table of blood glucose in men( by age).

How to properly prepare for the study of

There are various types of tests for blood sugar( total, biochemical, sugar, immunological), so you should prepare for them in different ways. Before submitting the material for analysis, do not eat food and liquids. When you eat, insulin is released to bring the monosaccharides back to normal. In addition, you should pay attention to the menu before submitting the analysis. Food containing fatty and high-carb foods, even after 10-12 hours increases the level of glucose. In this case, it is necessary that the last meal took 14 hours.

But these are not the only reasons that influence the result of the general analysis. Other indicators include exercise, various emotional states, infectious diseases, and stressful situations. The result of the analysis will change if you take a walk before going to the polyclinic. A training in sports and hard physical work will greatly distort the test, so the day before the delivery of samples it is desirable to abandon it. Otherwise, the results of the analysis will not reflect the true picture.

It is recommended to sleep well at night, and in the morning one should not worry, and then the accuracy of the results will be high. And also do not wait for the planned trip to the doctor, it is better to take tests ahead of schedule if there are symptoms that cause anxiety. These include:

  • skin itching;
  • strong thirst;
  • frequent urination;
  • rapid weight loss for no reason;
  • furunculosis on the skin;
  • fungal diseases.

These signs indicate the onset of the development of diabetes. In this case, in addition to the analysis for glucose, it is necessary to examine the blood for glycated hemoglobin, which will help to accurately diagnose. Twice a year you have to go to a polyclinic to take the sugar test for a healthy person. For patients with diabetes mellitus, sometimes the test is done several times a day( with a glucometer) for the proper administration of insulin and a special diet. The norm of blood sugar in men after 40, 50 and 60 years is presented above.

Glucose Tolerance

This test is performed after initial glucose testing. In warm water( in a volume of 200 ml), dilute 75 g of glucose and drink it. After two hours, they take blood again. In this case, it is necessary that the patient does not eat or drink, but simply sit for two hours, otherwise the result of the analysis will turn out to be wrong. If the susceptibility is disturbed, the sugar concentration will be 7.8-11.1 mmol / l. If the disease has already developed, then these figures will be much higher.

Blood glucose is normal in men by age table

An increase in blood sugar can occur with the following pathologies:

  • heart attack;
  • acute disturbance of cerebral circulation;
  • acromegaly.

A low level is possible due to the appearance of an endocrine tumor of the pancreas or insulinoma with a huge production of insulin.

How the blood sugar is regulated

The upper blood sugar for men, as for children and women, is regulated by hormone insulin. The lower norm is coordinated by the following complex:

  • glucagon - sends the special cells that are contained in the pancreas;
  • epinephrine and norepinephrine, as well as glucocorticoid hormones that are produced by the adrenal glands;
  • in the thyroid gland has its own special cells that increase the level of glucose;
  • from the hypothalamus and the pituitary gland commands come in that activate the adrenal glands.

In addition, the visceral nervous system can also influence the hormonal processes. Parasympathetic department reduces the amount of sugar, and sympathetic - increases.

Blood sugar content

The blood glucose level in men is 3.3-5.5 mmol / l. Sexual accessory is not relevant to the content of this substance. The study is performed on an empty stomach. The best time for this procedure is morning time, food should be absent in the body of the individual for eight hours. Infections, as well as lack of sleep can affect the result. In most cases, the biomaterial is taken from the middle finger. What is the permissible blood glucose in men?

The allowable concentration should not exceed the threshold of 5.6 mmol / l. When venous blood is taken, the optimal level will be in the range from 4.0 to 6.1.The disorder of susceptibility to glucose is noted at the level of it on an empty stomach of 5.6-6.6.This condition is called tolerance and is considered a harbinger of a serious pathology called diabetes mellitus. For the correct diagnosis, a laboratory test for glucose tablets tolerance should be made.

If the results of a general blood test exceed 6.7 mmol / l, those are the permissible blood glucose levels in men, this indicates the presence of diabetes. Nevertheless, additional tests are required to make sure the diagnosis is correct:

  • is a special test for glucose tolerance;
  • repeated analysis must be taken on an empty stomach;
  • specify the amount of glycosylated hemoglobin.

the glucose in the blood in men is what is the permissible norm

After meals, the allowable sugar concentration should not exceed 7.8 mmol / l. If the level is below normal, then this indicates signs of a malfunction in the body.

Causes of elevated blood sugar

Code is violated by the norm? The level of glucose in the blood in men can increase, but it does not happen just like that. If a person does not have bad habits and eats properly, then this can become an indicator of the disease. The main causes of increased levels of glucose:

  • smoking;
  • alcohol;
  • the immense use of food, which contains easily digestible carbohydrates;
  • diabetes mellitus;
  • frequent stress;
  • use of diuretics, steroid as well as contraceptives;
  • endocrine diseases;
  • diseases of internal organs, such as kidneys, pancreas.

Diet for reducing the sugar level

Surplus sugar can be removed with a special diet, which implies the exclusion of easily digestible carbons, which are found in the following products:

  • fast food;
  • baking, confectionery and sugar;
  • fried, smoked products;
  • marinade;
  • juice from concentrates;
  • carbonated and alcohol-containing beverages.

the norm of sugar in the blood in men after 40 50 60 years

For the passage of metabolic processes in normal mode it is recommended to use the following products:

  • vegetables and greens;
  • berries and fruits;
  • green tea;
  • fresh meat;
  • seafood;
  • nuts.

To the correct nutrition should also add exercise or walking.

Reduced blood sugar

It is often observed and a lowered level of glucose in the blood( the norm in men is described above), which is less than three mmol / l. This pathology is called hypoglycemia. The reasons that cause it: stress, prolonged hunger, a lot of physical activity, alcohol and diabetes. Hypoglycemia is a serious disease, as a result of which a man disrupts the supply of oxygen to the vessels of the brain. As a result of oxygen starvation, coma may occur. Signs of a decrease in blood sugar:

  • dizziness and general weakness;
  • frequent heartbeat;
  • is a stable headache;
  • severe malaise, sweating;
  • likely cramps.

To control the blood sugar in healthy men, it is desirable to do an analysis twice a year.

How to restore the sugar level to the

norm If the deviations from the allowed values ​​are small, they can be adjusted by the power mode. Often, hyperglycemia is detected after the diagnosis of glucose in the blood of men. The norm is slightly overpriced, therefore it is recommended to reduce the amount of carbohydrates contained in food. To do this, do not eat white bread, products containing sugar, pasta, potatoes, wine, carbonated drinks. It is recommended to increase the consumption of foods that lower sugar. These include tomatoes, cabbage, cucumbers, onions, beans, pumpkin, celery.

blood sugar for men

It is not necessary to worry much if hypoglycemia was detected following the results of testing the blood glucose level in men. The norm, as already mentioned, is about three mmol / l, but if the result is somewhat lower, it is desirable to increase the intake of proteins, which are in sufficient quantities in products from milk, lean meats, beans, nuts. Preventive measures of both increased and lowered blood sugar content are provided by proper diet and physical exercise. With an increased sugar content associated with illness of internal organs participating in the turnover of glucose, it is necessary to treat the underlying disease( pathology of the liver, pancreas, pituitary gland).

With an insignificant level of hyperglycemia, the patient is prescribed medicines that gradually reduce the amount of sugar in the blood, but do not increase the formation of insulin. With insulin deficiency, an individual dosage of the drug is selected for each patient, which is administered subcutaneously.


Knowing the amount of sugar in the blood is very important. His norm is in direct proportion to age and has certain limits, so everyone can monitor their condition and apply to the treating doctor for any abnormalities. The earlier a diabetic patient turns to a clinic for a specialist, the more he has the chance to improve his health.
