The flow of all metabolic processes in the human body is closely interrelated and the violation of such a mechanism can lead to various negative consequences.

Glucose rate in the blood allows you to track normal functioning internal organs and their systems and, if there are any failures on early stages eliminate the development of various diseases.

The main hormone, which regulates the blood glucose level (norm) is insulin produced by the pancreas.

At the same time, there are few, no less important, hormones are actively involved in this process.

• adrenaline and norepinephrine, which are produced by adrenal glands;
• hormone glucagon produced by alpha cells of the pancreas
• hormones thyroid gland;
• special "teams" hormones for the production of which certain brain departments are responsible;
• cortisol and corticostrol;
• hormone-like substances.

In addition, the control function for the work of all hormones in the body bears the autonomic nervous system.

The production of glucose occurs from sucrose, glycogen and starch incoming during food, its synthesis comes from glycogen in the liver, amino acids, lactate and glycene. In hormones human organismwhich carry hypoglycemic effects include insulin, glucagon, somatotropin, thyrotrops, dexamethasone. Under the influence of their regulatory mechanisms, a normal exchange of carbohydrates in the body is ensured.

The normal level of glucose in the blood largely depends on the lifestyle of man and various environmental factors.

Glucose functions in human body

Futing glucose and carbohydrate metabolites exchange process They are one of the main participants who provide the human body with the necessary energy and provide cells with oxygen. If a long time is observed reduced or increased quantity Such "participants" may cause the development of various pathological processes. That is why it is so important to periodically check the content of glucose in the blood, and when it dishes it from the regulatory indicators, to take appropriate measures.

Coming along with food sugar, due to physiological features The human body cannot immediately be synthesized into glucose and absorbed by cells and tissues. This requires the participation of special enzymes that split it to the state of glucose. Such a group of enzymes is known called Sakharaz. As a rule, such enzymes are produced by the pancreas and intestines, after which they penetrate the blood in the form of glucose. Its main source is food that enroll in the body when eating.

This method of enrichment glucose is not the only one. The human body has a property to preserve a certain amount in the form of backup reserves. And if necessary, use your own intracellular reserves in the form of glycogen. Stable and normal blood glucose readings are the key to the proper performance of the brain, skeletal muscles and hearts. If the body begins to be observed in the form of a disadvantage or excess sugar, it becomes the cause of many pathprocesses.

A person has the development of energy starvation at the cellular level as a result of a small amount of carbohydrate incoming carbohydrates. In the presence of long hypoglycemia, first of all, the brain and nerve cells begin to suffer.

With an excess of sugars, it begins to postpone in tissue cells.

That is why, the long-term flow of hyperglycemia has a negative effect on their functions - the kidney tissues, organs and the cardiovascular system are affected.

Manifestations of anomalous blood glucose level

Glucose levels in the blood and target levels. The presence of a high blood glucose level makes you more prone to other health problems, so it is very important to maintain the blood glucose level as close as possible to the norm. Your doctor or nurse will help you with this.

Testing your own blood glucose

The blood test reflects your average blood glucose level during the last 2 - 3 months. If you find that the achievement or stay at the target level affects your daily life and worsens the situation, you must discuss it with a doctor or nurse. This can be done more often if the blood glucose level changes quickly. Typically, blood glucose testing is carried out by your doctor or nurse. But some people, such as people who use insulin, could make it at home using a dial to test at home.

What are the indicators normative?

Sugar level

By controlling the level of sugars in the blood, people can timely identify deviations from regulatory indicators and diagnose arising disorders in a timely manner.

In Russia, the main unit for measuring the level of glucose in venous blood is Millimol for one liter.

Permissible sugar content for all healthy people It should vary from 3.2 to 5.5 mmol per liter. Normal is also considered to increase this value to the mark of 7.7 mmol per liter. Such indicators are applicable for blood tests from the finger. In the Clinical Medical Laboratory, the biomaterial is taken from Vienna. In this case, permissible norms Sugar in blood increase to 6.1 mmol per liter.

In young children, the normal glucose indicator may be slightly lower than in adults. Depending on the age, the regulatory indicators must correspond to the following numbers:

1. For babies up to a three-year period, blood fence to determine sugar performance is rare enough, since the glucose level is sufficiently unstable and can have significant fluctuations. At the same time, as regulatory data, it is customary to adhere to a level from 2.8 to 4.4 mmol per liter.
2. In children from 3 to 6 years, the indicators may vary from 3.3 to 5.4. In about the same limits, they persist until the child reaches adolescent age.
3. In the period from 11 to 14 years, the glucose indicators from 3.3 to 5.6 are considered normal, a slight increase in which may indicate sex maturation.
4. For all adults, the blood sugar level should vary from 3.3 to 6.5 mmol per liter.

With age, sugar in the blood may increase, that is why in the elderly, the normal level of glucose ranges from 4.6 to 6.4 mmol per liter.

It is worth noting that pregnant women, as well as women during the climax period may have an elevated blood glucose level. Such a phenomenon is considered absolutely normal and is associated with the occurrence of hormonal imbalance.

There are special online tables of indicators that show the norm for different age groups of people. They allow you to track blood glucose levels, according to the results of the studies, and in case of any deviations, seek help from medical professionals.

What are the types of diagnostic studies and for what are they intended for?

Diagnosis on the determination of the amount of blood sugars can occur using various modern techniques.

The most familiar for each person is the blood fence from veins or fingers for laboratory analysis.

Under the conditions of the house, such an analysis is carried out using a special device - a glucometer.

As a rule, laboratory analysis is carried out in the following cases:

• planned preventive inspections;
• in the presence of a large amount of excess weight, the presence of problems with the performance of the kidney or liver;
• with the development of diseases of the thyroid gland, adrenal glands or pituitary;
• as controlling procedures during the manifestation of diabetes or the state of the preceding him;
• women during pregnancy to prevent the possibility of manifestation of gestational type diabetes.

Such a blood test must be carried out exclusively on an empty stomach that the result obtained was as reliable as possible. It is recommended to implement the last meal of about ten or twelve hours before the appointed procedure. It is not necessary on the eve of the delivery of the test material to load the body with excessive physical labor or exposing itself to a stressful state. If, according to the results of the candidal blood, the glucose indicator is observed from seven Millimol per liter, the medical specialist appoints additional diagnostics. Since such results indicate the development of the pathological process in the body.

Another type of blood delivery is called the conduct of the procedure "with the load". The main purpose of its implementation is to obtain the result, as the patient's body responds to the receipt of sugars and how quickly its restoration and return to normal indicators glucose.

Often prescribed when suspected diabetes Or presence different failures In the exchange of carbohydrates. In addition, it is mandatory for the analysis of blood "with the load" of pregnant women and those categories of patients who have been discovered sugar in the urine.

The diagnostic procedure involves the fence of the material under study twice with the interval of two hours:

1. The first time the blood from the veins is taken in a patient on an empty stomach. After that, a person drinks 75 g diluted glucose in water.
2. After the specified period of time (after 2 hours), a re-election of blood occurs to track how much glucose indicators correspond to the norm.

Ideally, when conducting a re-analysis, the results should not exceed the mark of 7.8 mmol per liter.

To determine the development of diabetes or the presence of an exceptional state, a test may be appointed glycated hemoglobin (Hemoglobin compound with glucose). Thanks to this diagnosis, you can see the blood sugar level over the past two or three months.

In addition, dynamic indicators allow you to determine the effectiveness of the therapeutic treatment of diabetics.

What causes and symptoms of deviations from regulatory data exist?

Disagree from generally accepted norms in a large or smaller side can become a signal of what is failed in the work of one or several organs.

Deviations from the norm may cause development in the body of various pathological disorders.

With a significant increase in the level of glucose in the blood, there is a manifestation of hyperglycemia, which may occur under the influence of several factors.

These factors are the following:

1. Lifeline lifestyle together with improper nutrition and excessive emotional loads. Such reasons often become also harbingers for the development of diabetes.
2. Pathological processes arising in the pancreas - tumor different species or pancreatitis in acute and chronic forms.
3. Diseases of the kidneys, liver or cordial system organs.
4. Thyrotoxicosis and acromegaly.
5. Therapeutic treatment using certain groups of drugs.

Most often, the increased level of sugar in the blood is accompanied by the manifestation of the following symptoms:

• permanent dryness in oral cavity and strong attacks thirst, which in reinforced form begin to manifest itself at night;
• the manifestation of excessive appetite and, as a result, a sharp increase in body weight, at the same time, it should be noted that there are exceptions in which a person, on the contrary, begins to lose weight rapidly and greatly;
• itching skin;
• there is a common weakness in the body, feeling chronic fatigue and lethargy;
• significance is significantly increased;
• problems of S. bladder In the form of frequent urges to urination.

Too low indicators are a manifestation of a hypoglycemic state, which, as a rule, is formed as a result of insufficient glucose intake in the body.

The main reasons that can lead to a drop in blood sugar levels below the regulatory data are:

1. Long hunger strikes or adherence to unbalanced "hungry" diets.
2. As a response response to the reception of certain groups of drugs. To date, there have been frequent cases when women take sugar-remedy for weight loss. The result of such "self-medication" can be the state of the hypoglycemic coma.
3. Alcoholism.
4. Renal or heart failure.
5. Excessive physical exercise, unbearable for the human body.
6. Improper work of the pancreas.
7. Cancer diseases.
8. Hormonal imbalance, which leads to the development of excessive amounts of insulin.

If the state is observed, the following symptoms may appear:

• there are dizziness and feeling general weakness in organism;

A healthy level of glucose in the blood is a pledge of productive physical and mental labor. What are the performance of sugar optimal about what they can testify and how to adjust them?

Glucose rate in blood: hypo- and hyperglycemia

The main task of B. carbohydrate exchange Metabolites and glucose perform: they provide body tissues with energy and maintain cellular breathing. Changing the level of blood glucose content - increase or decrease - has bad influence on human health.

Control the level of sugar allows you to avoid a number of dangerous consequences.

Short course: Glucose role in the human body

From the school year of chemistry, it is known that sugar, like its carbohydrate congor, cannot be assimilated by the body without prior splitting. In the aquatic environment, special enzymes, recognize which helps the end of "-AZ" in the title, affect the chemical structure of the sugar, changing it to glucose compounds.

For the assimilation of the human body split to glucose sucrose correspond to the pancreas and the delicate intestine.

In glucose support need muscles of a skeleton, cardiovascular and central nervous Systems. Save the normal level of "sugar" allows proper nutrition And the inclusion in the diet foods, with a rich content of carbohydrates.

Deviations from the regulatory borders of the content of glucose compounds entails a number of serious consequences.

1. Low blood sugar leads to energy starvation of cells, which, in turn, limits their functional abilities. In cases of development chronic diseasesassociated with glucose starvation, a person threatens the defeat of the brain or nerve cells.
2. Exceeding healthy norms provoke glucose laying and subsequent damage to fabric proteins. In patients with hyperglycemia - elevated blood sugar levels - there is a destruction of tissues of such organs as kidneys, eyes, heart, vessels. A huge blow takes the nervous system.

Analyzing procedures

Investigate the level of blood content of glucose compounds help two ways: blood test on glucose (sugar), on an empty stomach with sugar "load". The meaning of such events has both preventive and therapeutic meaning: testing assistance helps to diagnose a number of diseases, including:

• obesity;
• pathology of internal organs;
• development of hyper- and hypoglycemia;
• prevention and monitoring of diabetes.

The attending physician is repelled from the results obtained, the diagnosis is diagnosed or if the share of doubt is present, sends to additional laboratory tests to study the patient's hormonal and enzyme background.

Most often, a test of tolerance to sugar becomes the continuation of the standard analysis on glucose.

Essence this method It comes down to passing the sick blood of two types: an empty stomach and after receiving a certain amount of glucose.

Blood glucose concentration: adults, pregnant women, children

However, after analyzing the blood glucose level, the results obtained are checked with a table of healthy sugar content devices depending on the age of the patient.

Glucose rate in the blood in children, women and men - table by age:

More accurate results of analyzes for blood glucose level children's body Normally should have the following lower / top thresholds:

In most cases, if the conditions of the analyzes were performed were observed, and their indicators range from 5.5 to 6.1 mmol / l, the attending physician issues the direction for an additional examination - glucose-oleraidity. Only after this test, the specialist can voiced the diagnosis.

Pregnancy leads to significant changes female organism. Thus, the average blood sugar rate during pregnancy is 3.3 - 6.6 mmol / liter.

Movement beyond these coefficients testifies to the development of gestational diabetes, which, due to the increase in the number of ketone and reducing the level of amino acids, postpartum period Can go to the diabetes of the second type.

By the 28th week it is necessary to conduct an oral watch check of the glucose level. The optimal result is an indicator that does not exceed the figure of 7.8 mmol / l. If an increase in sugar content is observed, a test is carried out in three hours, during which the pregnant woman is entered by the increased double compared with the previous analysis of the Glucose dose. The result of receiving 100 g of glucose should not exceed the following indicators:

Sugar is not normal: the causes of the development of hyper- and hypoglycemia

We see that, in addition to the "external" factors, the device of the human body is played in an individual case.

So, for example, after an expiration, a maximum, 24 hours without food, when the exhaustion of glycogen reserves occurs, internal glucose sources begin to activate in the human body.

As a raw material for glucose synthesis is used:

• dairy acid: it hides in the muscles that have experienced a load and red blood cells;
• glycerol: forces due to the fermentation of adipose tissue;
• amino acids: formed due to the decay of protein (muscle tissue).

It is worth noting the danger of glucose synthesizing the body through the use of amino acids, which is actually eating their own muscle tissue. There are cases of "self-stirring", reaching the heart, smooth intestinal musculatory and vascular system.

Why can blood glucose level be elevated or lowered? Causes of low or increased level Glucose in the blood can be hidden in working disorders endocrine system, as well as pathologies of such organs such as pancreas, kidneys, liver.

Significant influence on the degree of "saccharity" of the blood is provided by human diseases at the moment: infarction, stroke, diabetes mellitus. Characteristic "decreases" of insulin levels, except the above, are alcohol poisoning or chemicals, an overdose of insulin, steroids, amphetamines, vegetative disorders, malignant tumors.

Returning to healthy indicators

A man who placed the goal to return the blood sugar level to normal indicators should prepare for active and hard work on themselves, adjusting habits and lifestyle.

Minor deviations from established norms require healthy nutrition. Thus, the diet of the patient with hyperglycemia should include a minimum of carbohydrates. Under food taboos, products with high sugar, bakery and pasta of wheat flour of high grade, potatoes, wine and carbonated drinks are falling.

It is important to take care of the introduction in daily menu Vegetable "opponents" of sugar: cabbage, tomatoes, cucumbers, eggplants, pumpkins and so on.

Dosage of sacharo-substitutes, actively attracting the attention of diabetics, must prescribe a doctor: excessive use of these substances can lead to disorders gastrointestinal tract and the development of a deceptive feeling of hunger.

Hypoglycemia is an insufficient level of blood glucose - also requires the correction of the food culture. The diet should be aimed at using high-fingered products (nuts, beans, dairy and meat non-fat products).

The process of treating substantial deviations in "sugar" testimony should be entrusted with a medical specialist, since, as mentioned earlier, the abnormal movements of the blood sugar level often become symptoms of organs of organs included in the process of glucose turnover.

Accordingly, a full examination is required, an integrated approach and the compilation of an individual course of therapy.

Medicinal preparations in the fight against hyperglycemia are aimed at a smooth reduction in sugar levels without enhancing insulin production. In most cases, the attending physician appoints funds such as sulfanylmur and biguenides.
