Diabetes mellitus is a pathology, the main manifestation of which is an increase in blood sugar. The main symptoms of the disease are associated with hyperglycemia, and its compensation can predict the likelihood of diabetes complications.

Constantly increased level glucose damages vascular wall and leads to the development of diseases of the kidneys, retina, peripheral nervous system, diabetic foot, angioneuropathies varying degrees expressiveness.

Improper treatment of diabetes mellitus or the presence of severe concomitant diseases can cause fluctuations in blood sugar with the development diabetic coma which requires emergency medical attention.

Causes of hyperglycemia in diabetes mellitus

Increased blood sugar with diabetes mellitus Type 1 is associated with an absolute deficiency of insulin. The beta cells in the pancreas are destroyed due to an autoimmune type of reaction. Viruses, toxic substances, medications, and stress provoke this immune disorder. The disease occurs in genetically predisposed patients.

In type 2 diabetes, insulin secretion for a long time may not differ from the norm, but insulin receptors do not respond to this hormone. The main factor in the development of diabetes mellitus is obesity due to hereditary predisposition. The second type of diabetes occurs with a relative deficiency of insulin.

With an absolute or relative lack of insulin, glucose cannot enter cells and be processed for energy. Therefore, it remains in the lumen of the vessel, causing an influx of fluid from the tissues, since it is osmotically active substance. Dehydration develops in the body, as the kidneys excrete the diseased volume of fluid along with glucose.

The course of diabetes mellitus is assessed according to the severity of hyperglycemia:

Mild degree: fasting blood glucose below 8 mmol/l, no glucosuria or traces of glucose in the urine. Compensated by diet, angiopathy is functional.
Moderate severity: fasting sugar up to 14 mmol/l, glucosuria per day not exceeding 40 g, ketoacidosis occurs occasionally. Treatment is carried out with tablets or insulin (up to 40 units) per day.
Severe degree: glycemia above 14 mmol/l, high level of glucosuria, insulin is administered in large doses, diabetic angioneuropathy is present.

Thus, if blood sugar is 16 and is this dangerous for a diabetic, the answer to such a question can only be positive, since this sign refers to severe diabetes.

This condition can develop into acute complication diabetes – diabetic ketoacidosis.

Causes of ketoacidosis in diabetes mellitus

Ketoacidosis develops when high level glycemia and an increase in the number of ketone bodies in the blood. Its cause is insulin deficiency. Type 1 diabetes may begin with ketoacidosis when late diagnosis, and in type 2 diabetes it occurs in late stages diseases when the reserves of the pancreas are exhausted.

Conscious or forced refusal of insulin also leads to high hyperglycemia and ketoacidosis, concomitant diseases and injuries, operations, taking hormones and diuretics, removal of the pancreas.

Insulin deficiency leads to increased levels of glucagon, growth hormone, cortisol and adrenaline in the blood, which stimulate the breakdown of glycogen in the liver and the formation of glucose in it. This leads to an increase in glycemia. In addition, in the absence of insulin, the breakdown of proteins and fats begins with an increase in the level of amino acids and fatty acids in the blood.

Since there is no glucose in the cells, the body begins to obtain energy from fats. During such reactions, ketone bodies are formed - acetone and organic acids. When their levels are higher than the kidneys can remove, ketoacidosis develops in the blood. Fats from foods eaten do not take part in ketogenesis.

This condition is accompanied by severe dehydration. If the patient cannot drink enough water, then losses can amount to up to 10% of body weight, which leads to general dehydration of the body.

The second type of diabetes with decompensation is often accompanied by a hyperosmolar state. Since the available insulin prevents the formation of ketone bodies, but since there is no reaction to it, hyperglycemia increases. Symptoms of hyperosmolar decompensation:

Copious urine output.
Unquenchable thirst.
Nausea.
Losing body weight.
High blood pressure.
Elevated levels of sodium in the blood.

The causes of the hyperosmolar state may be dehydration due to high dose diuretics, vomiting or diarrhea.

There are also combinations of ketoacidosis and hyperosmolar decompensation.

Signs of ketoacidosis

Diabetes mellitus is characterized by a gradual increase in symptoms of hyperglycemia. Ketoacidosis develops over a day or more, with dry mouth increasing, even if the patient drinks a lot of water. At the same time, patients become increasingly unwell, headache, bowel dysfunction in the form of diabetic diarrhea or constipation, abdominal pain and occasionally vomiting.

An increase in hyperglycemia leads to impaired consciousness, the appearance of noisy and rapid breathing, the skin is dry and hot to the touch, the smell of acetone comes from the mouth, when pressing on eyeballs their softness is revealed.

Diagnostic studies confirming ketoacidosis should be performed at the first manifestations of hyperglycemia. A blood test reveals an increase in sugar of more than 16-17 mmol/l, ketone bodies are present in the blood and urine. The following tests are performed in a hospital setting:

Glycemia – hourly.
Ketone bodies in the blood and urine - once every 4 hours.
Blood electrolytes.
General blood analysis.
Blood creatinine.
Determination of blood pH.

Treatment of hyperglycemia and ketoacidosis

Patients with signs of ketoacidosis are immediately prescribed a drip with saline solution and 20 units of short-acting insulin are injected intramuscularly.

Then insulin continues to be injected intravenously or into the muscle at a rate of 4-10 units per hour, which inhibits the breakdown of glycogen by the liver and inhibits ketogenesis. To prevent insulin from settling, albumin is added to the same bottle.

It is necessary to reduce hyperglycemia slowly, since a rapid drop in sugar can lead to osmotic edema, in particular cerebral edema. During the day you need to reach a level of 13-14 mmol/l. if the patient cannot eat food on his own, then he is prescribed 5% glucose as a source of energy.

After the patient regains consciousness and glycemia has stabilized at 11-12 mmol/l, he is recommended to: drink more water, you can eat liquid porridge, mashed potatoes, pureed vegetable or cereal soup. Insulin for such glycemia is prescribed subcutaneously, first in fractions, and then according to the usual regimen.

When removing the patient from the condition diabetic ketoacidosis the following drugs are used:

Sodium chloride 0.9% in an amount of 7-10% of body weight in the first 12 hours.
Plasma substitutes for systolic pressure below 80 mm Hg. Art.
Potassium chloride under blood level control. First, the patient receives potassium infusions, and then potassium tablets for a week.
Infusion of soda is used to correct acidosis very rarely.

To treat the hyperosmolar condition, 0.45% sodium chloride solution is used and insulin is not used or is prescribed in very small doses. Recommendations for conscious patients: drink a lot of water, eat dishes pureed, simple carbohydrates are excluded. To prevent thrombosis, elderly patients are prescribed heparin.

It is possible to prevent an increase in blood sugar and the development of ketoacidosis in diabetes mellitus only by constantly monitoring glycemic levels, following a diet limiting easily digestible carbohydrates, drinking enough water, adjusting the dose of insulin or tablets when concomitant diseases, excessive physical and emotional stress.

Why is blood sugar 16 dangerous and what to do in this case?

What does blood sugar 16 mean? Glucose constantly circulates throughout the body along with the bloodstream. It is this that provides nutrition for it and helps organ tissues receive the necessary energy for all functions. But what happens when this norm is violated? Ideally, it does not have a wide fluctuation range, so when it goes beyond the limits, they always talk about an increase or decrease in blood sugar. Without glucose, the body cannot function normally; it has nowhere to get energy. But with too much of it, it will not give a boost of energy, rather the opposite. Therefore, it is very important to know about sugar and its norm, which will help avoid diabetes.

Normal blood sugar

Glucose constantly enters the body of every person from the outside. It is not produced by the body and is replenished with food intake. These are not only sweets or fruits, but also foods rich in carbohydrates. When sugar increases, hyperglycemia occurs, and when sugar decreases, hypoglycemia occurs. Blood sugar should be from 3.9 to 5. On average, these indicators are healthy people are approximately 4.6 mmol/l.

After a morning meal, glucose rises to 5.5, but gradually during the day it returns to its usual norm.

To determine its level, several tests are performed:

Sugar on an empty stomach.
Glucose tolerance.
Test 2 hours after eating.
Glycated hemoglobin.

Thanks to this approach, it is best to learn about the amount of glucose and detect diabetes in advance. With the development of this disease, sugar does not rise immediately. Everything happens gradually, and problems accumulate, causing destruction to the blood vessels. Therefore, at first, when checking your sugar on an empty stomach, you will notice that it is indistinguishable from normal readings. At the same time, changes inside the body under the influence of the disease have already begun. Therefore, such checks help to pinpoint the problem.

You can donate blood for glycated hemoglobin in any laboratory. At home, it is enough to use a familiar glucometer. To do this, it is necessary to test 2 hours after eating, even with normal fasting values.

High sugar and its consequences

There are three degrees of severity:

light;
moderate severity;
heavy.

Whenever light form glucose will increase to 10 mmol/l. Moderate increases to 16, and severe exceeds the glucose level of 16 mmol/l. In this case, a precomatose state is possible. What to do in this case and how to find out about an increase in sugar?

There are some symptoms due to which you can notice an increase in sugar. Often hyperglycemia is not noticed, because in most cases it is asymptomatic.

But some symptoms are quite common and can be used to determine the presence of a problem:

constant thirst;
dry skin;
dry tongue;
sudden weight loss;
poor skin regeneration;
fungal diseases with long-term treatment;
acetone aroma when exhaling;
increased breathing;
fatigue.

If you do not take care of reducing sugar and do not start treatment, this will lead to complications. When ketoacidosis or hyperglycemic coma occurs, it is important to immediately begin the necessary manipulations to lower glucose levels. Otherwise it is possible death, which in acute complications accounts for about 10% of deaths.

At chronic complications the situation is no better. Problems begin with internal organs, causing diseases of the kidneys, nervous system, and blood vessels. A person’s vision deteriorates, problems begin with lower limbs. And the most dangerous thing is the increased risk of heart attack or stroke.

The walls of blood vessels are gradually destroyed from the inside and become too rough. Over time, this leads to a layering of inside calcium, reducing the diameter. This damage is called angiopathy. As a result, those organs and systems where such layers occur suffer. Therefore, in patients with diabetes, amputations of the feet, heart and brain problems can be observed.

If you have type 1 or type 2 diabetes, you need to check your glucose level with a glucometer at least 4 times a day. This will help you select the dose of insulin most accurately and not harm the body. If a person is not insulin dependent, then measurements can be taken 2 times a day. But at the same time, monitor your diet very carefully.

For diabetes mellitus it is necessary constant control glucose. A critical blood sugar level is the start of the development of irreversible processes in the human body. Short-term increases are dangerous due to immediate complications, and long-term critical glucose levels lead to damage to blood vessels and organs. It is important to know what is normal and what sugar level is considered critical.

Sugar norm

IN healthy body The blood glucose level (fasting) should not be higher than 3.5-5.5 mmol. After eating, the value increases and should not exceed 7.8 mmol. These indicators are generally established medical level for blood samples taken from a finger prick. U venous blood permissible level will be higher - 6.1 mmol on an empty stomach, but it is also considered normal.

The maximum sugar level for diabetes should be no more than the amount when glucose is excreted in the urine. 8-11 mmol is considered slight promotion, blood sugar 17 - moderate condition, blood sugar 26 - severe stage of hypoglycemia. negatively affects the functionality of the body, leads to irreversible, serious violations. Blood sugar levels according to age characteristics, are indicated in the table.

Dangerous level

A reading of 18 mmol/l is already considered a complication. And blood sugar of 20 mmol/l and above provokes the development of irreversible pathologies that have a bad effect on human health. But it would be wrong to equate this indicator to all people. For some, irreversible consequences begin at 15 mmol, while others do not feel any disturbances, even if the sugar is 30 mmol. It is difficult to unambiguously determine the overall lethal level of sugar in the blood; each person has the most high rate individual, taking into account general health.

Causes and symptoms of increase

An increase in temperature can cause a rise in blood sugar.

Diabetes is not the only cause of sudden increases in sugar levels. Stress, anxiety, pregnancy, various diseases may increase glucose levels. Deviations from the norm are associated with disturbances in the processing of carbohydrates. In this regard, doctors have identified several main reasons that can briefly raise sugar to 20 units or more:

poor nutrition;
sedentary lifestyle life;
temperature increase;
pain syndrome;
smoking and alcohol;
uncontrolled emotions.

Health problems associated with pathological changes functionality internal organs, cause persistent glucose levels. They are divided into groups depending on which organ is damaged:

organs of the gastrointestinal tract;
liver;
endocrine glands;
hormonal imbalance.

To reduce the indicator, you need to find out the reason for the increase and remove it.

Symptoms

Constantly elevated sugar leads to a loss of strength in the patient.

It is possible to determine the exact indicator by examining blood taken on an empty stomach. Constantly high sugar negatively affects a person’s well-being, causing characteristic symptoms:

prostration;
lethargy;
feeling of numbness in the limbs;
increased appetite;
constant thirst;
frequent urination;
persistent weight loss;
skin itching and rashes;
poorly healing wounds;
decreased sexual desire.

The clinical symptom that indicates an increased level of sugar (glucose) in the blood serum is called hyperglycemia. Hyperglycemia is diagnosed mainly with the development of diabetes mellitus or other diseases endocrine system. There are several conventional levels of expression of this symptom. With mild hyperglycemia, the sugar level is 6 - 10 mmol/l; for moderate damage - 10 – 16 mmol/l; in severe form - more than 16 mmol/l. When the sugar level exceeds 16.5 mmol/l, coma and precomatose state occurs.

Types of hyperglycemia

People with diabetes experience two types of hyperglycemia:

fasting hyperglycemia (when a person has not eaten for eight hours, the blood sugar level rises above 7.2 mmol/l);
hyperglycemia, which appears after eating, and the blood sugar level becomes above 10 mmol/l.

When a person who does not suffer from diabetes has a sugar level above 10 mmol/l after eating a large amount of food, this indicates that they are at high risk of developing type 2 diabetes.

Negative consequences

Why does hyperglycemia happen?

It is extremely important for patients to follow a diet. But do this only after consulting your doctor. You will have to keep under close control the amount of carbohydrates and calories contained in the food you consume. Patients are often prescribed insulin to treat hyperglycemia. When this symptom is non-diabetic in nature, it needs to be treated endocrine disease, which caused the development of the disease.

When you have high blood sugar, it is not only uncomfortable for your well-being, but also dangerous for your health. If high blood sugar persists long time- this can lead to short-term acute complications of diabetes - diabetic ketoacidosis and hypersmolar coma. Short-term but frequent increases in blood glucose levels are also very harmful to blood vessels, kidneys, eyes, and legs. It is because of this that complications gradually develop.

If your blood sugar has increased (this condition is called) - you must know how to properly bring it down to the optimal level - up to 4.8 - 6.5 mmol / liter. If you lower it thoughtlessly, you can lower it too much and “fall” into an even more dangerous state for the body - hypoglycemia.

We'll look at some of the options for lowering your blood glucose levels in the short term.

What are the signs of high blood sugar?

First you need to make sure that your blood sugar is high. The classic symptoms are:

Feeling very thirsty.
You often start going to the toilet to urinate.
The mouth feels dry.
Lethargy and fatigue develop (you cannot rely on this symptom alone, since it can also occur with).
You become irritable and uncomfortable.

Check your blood sugar levels

If you have diabetes and are taking medications that lower your blood sugar and can cause hypoglycemia, it is highly advisable that you measure your blood sugar levels with a glucometer before you begin to bring it down and bring it back to normal. This must be done in order not to accept some symptoms low sugar for hyperglycemia. This is especially important if you are being treated with insulin.

When should you seek medical help?

It is important to note that a very high level of glucose in the blood can be dangerous to health, so you should not bring it down yourself, but urgently need to call ambulance. If your breath smells like acetone or fruit, then you have developed diabetes and it can only be cured under the supervision of a doctor. At very high sugar(more than 20 mmol/liter), an even more formidable and life-threatening complication of diabetes develops - hypersmolar coma. In these cases, you do not need to reduce the sugar yourself, but urgently call a doctor.

Insulin injections will help reduce high blood sugar (but not for beginners)

If you are prescribed insulin, one way to lower your blood sugar is to take an insulin injection.

However, be careful, as insulin may take 4 hours or more to begin to act, and during this time the patient's condition may significantly worsen.

If you decide to reduce high blood sugar with insulin, use short-acting or ultra-short-acting insulin. These types of insulin begin to act very quickly. But be careful, because... overdosing can lead to and can be dangerous, especially before bedtime.

Blood sugar should be reduced gradually. Take small insulin injections of 3-5 units, measure your blood sugar levels every half hour and add small doses of insulin further until your blood sugar returns to normal.

If you have undiagnosed diabetes, it is strictly forbidden to lower your blood sugar with insulin on your own. Remember that insulin is not a toy and can be life-threatening!

Physical activity does not always help lower blood sugar

Physical activity can help lower your blood sugar, but only when your blood sugar is only slightly elevated and you do not have ketoacidosis. The fact is that if you have a high blood sugar level before physical activity, it will increase even more from physical exercise. That's why, this method not relevant for bringing glucose levels back to normal.

In this video, Elena Malysheva describes ways to lower blood sugar levels.

How to quickly reduce high sugar levels using folk remedies?

Remember that folk remedies lower sugar very gently; I use them only as preventive and auxiliary means. Alone folk remedies you will not be able to bring your sugar levels back to normal.

For example, they write that. This may be true, but this remedy will not lower your blood sugar quickly, especially if your blood sugar is above 10 mmol/liter.

Β miraculous folk remedies are believed, as a rule, by those who have developed diabetes for the first time and are not yet familiar with the realities. If you are categorically against treatment with insulin or sugar-lowering pills, then try taking a folk remedy and then measure your blood sugar levels. If it doesn't help, then call a doctor.

Drink more water

If your blood sugar levels are very high, your body will try to remove excess sugar from your blood through urine. As a result, you will need more fluid to hydrate yourself and initiate this self-cleaning process. Drink better plain water, drink a lot, but don’t overdo it, because... You can get water intoxication if you drink several liters of water in a short period of time.

Water is essential, but know that water alone will not bring down high blood sugar levels. Water is the most important thing aid in the fight against high sugar levels in the body.

Summary

If you have and you know how to use insulin correctly, take small injections of insulin, measure your blood sugar levels every half hour or hour and bring them back to normal. At the same time, drink plenty of water.
If you have type 2 diabetes, the prescribed antihyperglycemic drugs do not help you and you have never taken insulin, call your doctor. You cannot start insulin treatment on your own.
If your blood sugar level has risen for the first time, do not try to bring it down yourself with physical activity, high consumption of water or some folk remedies. If you have not yet been diagnosed with diabetes, but your sugar has risen, consult a doctor immediately; do not try to reduce sugar yourself at home, because this may lead to ketoacidosis or coma.

But what happens when this norm is violated? Ideally, it does not have a wide fluctuation range, so when it goes beyond the limits, they always talk about an increase or decrease in blood sugar.

After a morning meal, glucose rises to 5.5, but gradually during the day it returns to its usual norm.

To determine its level, several tests are performed:

High sugar and its consequences

There are three degrees of severity:

If a mild form occurs, glucose will increase to 10 mmol/l. Moderate increases to 16, and severe exceeds the glucose level of 16 mmol/l. In this case, a precomatose state is possible. What to do in this case and how to find out about an increase in sugar?

Therefore, in patients with diabetes, amputations of the feet, heart and brain problems can be observed.

blood sugar level is 16 mmol/l. They said that you can go into a coma. What kind of disease is this? Can you write?

Development comatose state is always a formidable sign, and if time is missed, changes in the patient’s body can become irreversible and lead to death.

Coma can develop either from a lack of sugar in the blood (hypoglycemic coma), or from an excess of sugar in the blood (hyperglycemic coma).

With hypoglycemia, coma develops acutely, the patient feels chills, hunger, trembling in the body, loses consciousness, and occasionally there are brief convulsions. In case of loss of consciousness it is noted profuse sweating: the patient is wet, “at least squeeze it out,” cold sweat.

Hyperglycemic coma develops gradually, over the course of a day or more, is accompanied by dry mouth, the patient drinks a lot, if at this moment you take blood for a sugar test, the levels are increased (normally 3.3-5.5 mmol/liter) by 2- 3 times. Hyperglycemic coma usually develops in patients with diabetes mellitus. Distinctive feature coma is that, in addition to complete loss of consciousness, the skin is dry, warm to the touch, and the breath smells of apples or acetone.

In general, it’s strange that they didn’t tell you anything but warned you about the coma

What sugar level is considered critical?

Diabetes causes irreversible changes in the body. And the reason for such changes is high or low level Sahara. Any significant deviations from the normal value (3.3–5.5 millimoles per liter) are dangerous to the health and life of the patient. Let's consider what glucose indicators are critical for a person and how to help him.

What does “critical level” of glucose mean?

In principle, for a healthy body, any increase in glucose above 7.8 mmol can be considered critical, since irreversible processes of destruction of the body begin above this line. The same can be said when this level drops below 2.8 mmol.

However, in diabetes, these indicators fluctuate within a very wide range, sometimes reaching an exorbitant 55 mmol or even more. To somehow imagine what this figure means, we note that in this state, one liter of blood contains 10 grams of sugar - two teaspoons.

A danger to the body is when glucose levels exceed 13–17 mmol per liter. In this condition, acetone is present in the urine. All patients can independently determine the presence of ketones in urine using test strips.

If blood sugar is over 10 mmol, then it also appears in the urine, and this indicator is also dangerous. In both cases, insulin should be administered. If this is not done, then there is a high risk of hyperglycemic coma.

A critical level of glucose also occurs when it suddenly decreases. Not all people tolerate low blood sugar equally: some experience clear symptoms of hypoglycemia at 3.2 mmol, while others feel well at a level of 2.5 millimol or even less.

Sometimes in diabetes there is a sharp relative decrease in glucose (up to normal limits) also causes signs of hypoglycemia. In all these cases, the patient should be given some easily digestible carbohydrates. If this is not done, glucose levels will continue to fall, causing loss of consciousness, seizures and, ultimately, death.

What level of sugar is considered fatal?

In patients with diabetes, the sugar level is 15–17 millimoles per liter. This contributes to the development of hyperglycemic coma. However, not everyone develops hyperglycemia at the same glucose levels. In some people, levels even up to 17 millimoles per liter do not clearly cause severe symptoms. That is why there are no certain indicators that are fatal for humans.

Pharmacies in Once again they want to make money off diabetics. There is a smart modern European drug, but they keep quiet about it. This.

There are some differences in the clinical course of hyperglycemic coma in patients depending on the type of diabetes. Thus, with insulin-dependent diabetes, dehydration and ketoacidosis quickly develop. On the contrary, with non-insulin-dependent diabetes, only dehydration progresses in patients. However, it can be very pronounced, so getting the patient out of it dangerous condition it can be difficult.

In severe diabetes, a person develops ketoacidotic coma. Most often, this condition occurs in patients with type 1 diabetes, complicated by an infectious disease. It is not uncommon to develop ketoacidotic coma with a low dose of insulin. The main symptoms of this condition are as follows:

excretion of sugar in the urine, which causes a lot of it;
rapid development of dehydration;
accumulation of ketone bodies in the blood due to the fact that body cells begin to consume fats for energy purposes;
weakness, drowsiness;
dry mouth;
dry skin;
appearance acetone smell from the oral cavity;
deep and noisy breathing(as a result of compensation high content carbon dioxide in the blood).

With a further increase in blood sugar, hyperosmolar coma develops. This condition is characterized by extremely high glucose levels (its level can rise to 55 mmol). Such numbers are limiting for the body. The state of hyperosmolarity is not accompanied by ketoacidosis. Despite this, such a coma requires emergency assistance. It develops gradually. The main signs of the development of hyperosmolar coma:

copious urine output;
the patient drinks a lot of liquid, but despite this, cannot quench his thirst;
after water the body loses a large number of minerals;
dehydration, weakness, drowsiness rapidly increases;
facial features become sharp;
dryness of the skin and oral cavity increases;
shortness of breath develops.

Only immediate hospitalization can prevent the death of a person. No home methods will help normalize the condition.

Critical sugar level during hypoglycemia

With a rapid decrease in glucose, hypoglycemia develops. This condition can develop spontaneously and is always life-threatening. Since the brain is the largest consumer of glucose, it is the first to suffer during hypoglycemia. People suffering from hypoglycemia require emergency medical attention.

With mild hypoglycemia, the following symptoms occur:

trembling and chills;
loss of sensation in the tip of the tongue;
limb weakness;
dizziness;
pallor, sweating;
the person is confused and cannot navigate in time and space.

If you immediately eat something sweet, this condition goes away. However, this must be done as early as possible, otherwise, as hypoglycemia progresses, the person may lose consciousness, and it will be much more difficult to save him.

In severe hypoglycemia, the patient loses consciousness. In this case, a glucagon injection can save him. The patient or his relatives need to constantly measure blood sugar levels in order to achieve their normalization.

What to do if hyperglycemic coma begins

If the patient experiences increasing nausea, vomiting, and signs of general malaise, it is likely that he has not only an upset stomach, but a sign of an incipient hyperglycemic coma. The principle of helping a person in this condition is frequent subcutaneous administration of short-acting insulin.

If two attempts self-correction glucose tests remain unsuccessful - you need to urgently call a doctor.

The patient must learn to correctly calculate the corrective dose of insulin in case of hyperglycemia, depending on the presence of acetone in the blood. The simplest method for calculating the correction dose is to administer 1 additional unit of insulin if the glucose level is elevated by 1.5 to 2.5 millimoles. When acetone appears, the amount of insulin must be doubled.

If you manage to achieve a decrease in glucose, you need to take quickly digestible carbohydrates. This must be done in order to prevent the development of so-called starvation ketosis. For vomiting, sweet tea is recommended.

Diabetes mellitus is often called the “silent killer.” After all, approximately 25% of patients are unaware of the development of a serious pathology. But diabetes is no longer a death sentence! Chief diabetologist Alexander Korotkevich told how to treat diabetes once and for all. Read more.

Prevention of hypo- and hyperglycemia

A diabetic should always know how to help himself in case of an unexpected low blood sugar.

You should always have glucose medication with you.
If the condition is stable, eating quickly digestible carbohydrates is not allowed.
It is absolutely necessary to conduct healthy way life, give up alcohol and cigarettes, exercise.
It is necessary to ensure that the type and amount of insulin administered fully corresponds to blood glucose levels.
To always know these indicators, it is imperative to have an accurate glucometer at home that allows you to quickly determine your glucose level. Having a glucometer will help you detect the moment of onset hyperglycemia and quickly respond to this process.
You need to learn how to calculate your insulin dosage yourself.

Remember that every person is fully capable of controlling diabetes and preventing glucose levels from deviating to critical levels.

How to quickly lower blood sugar levels for diabetics?

The diabetes incidence statistics are getting sadder every year! The Russian Diabetes Association states that every tenth resident of our country has diabetes. But the cruel truth is that it is not the disease itself that is scary, but its complications and the lifestyle it leads to.

Blood sugar 16: what to do and what are the consequences of a level of 16.1-16.9 mmol?

Constantly elevated glucose levels damage the vascular wall and lead to the development of diseases of the kidneys, retina, peripheral nervous system, diabetic foot, and angioneuropathies of varying severity.

Improper treatment of diabetes mellitus or the presence of severe concomitant diseases can cause fluctuations in blood sugar with the development of diabetic coma, which requires emergency medical attention.

Causes of hyperglycemia in diabetes mellitus

Increased blood sugar in type 1 diabetes is associated with an absolute deficiency of insulin. The beta cells in the pancreas are destroyed due to an autoimmune type of reaction. Viruses, toxic substances, medications, and stress provoke this immune disorder. The disease occurs in genetically predisposed patients.

In type 2 diabetes, insulin secretion may not differ from normal for a long time, but insulin receptors do not respond to this hormone. The main factor in the development of diabetes mellitus is obesity due to hereditary predisposition. The second type of diabetes occurs with a relative deficiency of insulin.

With an absolute or relative lack of insulin, glucose cannot enter cells and be processed for energy. Therefore, it remains in the lumen of the vessel, causing an influx of fluid from the tissues, since it is an osmotically active substance. Dehydration develops in the body, as the kidneys excrete the diseased volume of fluid along with glucose.

The course of diabetes mellitus is assessed according to the severity of hyperglycemia:

Mild degree: fasting blood glucose below 8 mmol/l, no glucosuria or traces of glucose in the urine. Compensated by diet, angiopathy is functional.
Moderate severity: fasting sugar up to 14 mmol/l, glucosuria per day not exceeding 40 g, ketoacidosis occurs occasionally. Treatment is carried out with tablets or insulin (up to 40 units) per day.
Severe degree: glycemia above 14 mmol/l, high level of glucosuria, insulin is administered in large doses, diabetic angioneuropathy is present.

Thus, if blood sugar is 16 and is this dangerous for a diabetic, the answer to such a question can only be positive, since this sign refers to severe diabetes.

This condition can develop into an acute complication of diabetes – diabetic ketoacidosis.

Causes of ketoacidosis in diabetes mellitus

The development of ketoacidosis occurs with a high level of glycemia and an increase in the number of ketone bodies in the blood. Its cause is insulin deficiency. Type 1 diabetes can begin with ketoacidosis when diagnosed late, and in type 2 diabetes it occurs in the later stages of the disease, when pancreatic reserves are depleted.

Also, high hyperglycemia and ketoacidosis are caused by conscious or forced refusal of insulin, concomitant illnesses and injuries, surgeries, taking hormones and diuretics, and removal of the pancreas.

This condition is accompanied by severe dehydration. If the patient cannot drink enough water, then losses can amount to up to 10% of body weight, which leads to general dehydration of the body.

Copious urine output.
Unquenchable thirst.
Nausea.
Losing body weight.
High blood pressure.
Elevated levels of sodium in the blood.

Causes of a hyperosmolar state may include dehydration due to a large dose of diuretics, vomiting, or diarrhea.

There are also combinations of ketoacidosis and hyperosmolar decompensation.

Signs of ketoacidosis

Diabetes mellitus is characterized by a gradual increase in symptoms of hyperglycemia. Ketoacidosis develops over a day or more, with dry mouth increasing, even if the patient drinks a lot of water. At the same time, patients experience increasing malaise, headache, intestinal dysfunction in the form of diabetic diarrhea or constipation, abdominal pain and occasionally vomiting.

An increase in hyperglycemia leads to impaired consciousness, the appearance of noisy and frequent breathing, the skin is dry and hot to the touch, the breath smells of acetone, and when pressing on the eyeballs, their softness is revealed.

Diagnostic studies confirming ketoacidosis should be performed at the first manifestations of hyperglycemia. A blood test reveals an increase in sugar more than mol/l; ketone bodies are present in the blood and urine. The following tests are performed in a hospital setting:

Glycemia – hourly.
Ketone bodies in the blood and urine - once every 4 hours.
Blood electrolytes.
General blood analysis.
Blood creatinine.
Determination of blood pH.

Treatment of hyperglycemia and ketoacidosis

Patients with signs of ketoacidosis are immediately given a saline drip and 20 units of short-acting insulin are injected intramuscularly.

It is necessary to reduce hyperglycemia slowly, since a rapid drop in sugar can lead to osmotic edema, in particular cerebral edema. Within 24 hours you need to reach the mol/l level. if the patient cannot eat food on his own, then he is prescribed 5% glucose as a source of energy.

After the patient regains consciousness and the glycemia has stabilized at the mol/l level, he is recommended to: drink more water, you can eat liquid porridge, mashed potatoes, pureed vegetable or cereal soup. Insulin for such glycemia is prescribed subcutaneously, first in fractions, and then according to the usual regimen.

When removing a patient from a state of diabetic ketoacidosis, the following drugs are used:

Sodium chloride 0.9% in an amount of 7-10% of body weight in the first 12 hours.
Plasma substitutes for systolic pressure below 80 mmHg. Art.
Potassium chloride under blood level control. First, the patient receives potassium infusions, and then potassium tablets for a week.
Infusion of soda is used to correct acidosis very rarely.

To treat the hyperosmolar condition, 0.45% sodium chloride solution is used and insulin is not used or is prescribed in very small doses. Recommendations for conscious patients: drink a lot of water, eat pureed meals, avoid simple carbohydrates. To prevent thrombosis, elderly patients are prescribed heparin.

It is possible to prevent an increase in blood sugar and the development of ketoacidosis in diabetes mellitus only by constantly monitoring the level of glycemia, following a diet limiting easily digestible carbohydrates, drinking enough water, adjusting the dose of insulin or tablets for concomitant diseases, excessive physical and emotional stress.

Blood sugar 17 - what does it mean?

IN last years The incidence of diabetes is becoming increasingly common, not only among older people, but also among young people. There are many reasons for this, but some of the main ones are inattention to one’s health and lifestyle, failure to consult a doctor in a timely manner, and ignoring the symptoms of the disease. Sometimes patients turn to medical institution when it turns out that blood sugar is 17 and there is a threat to life. This primarily applies to people with type 2 disease.

Type 1 disease causes disease of the pancreas, a disruption of its normal functioning. This type of disease is difficult to treat, and the patient must take regular insulin injections or take glucose-lowering medications, and avoid sweets, fatty, spicy and fried foods in the diet. The main thing is to correctly calculate the dose of insulin after each meal, give the body moderate physical activity– and this will ensure normal well-being. Such patients rarely have blood sugar 17, although overeating and untimely admission Insulin such a jump can happen.

Blood sugar 17: causes and consequences

You can control glycemia at home using a simple compact device - a glucometer. If you feel worse, you can quickly conduct a blood test and identify the cause.

What can cause the result: blood sugar 17 and why is it dangerous? This indicator is considered acute and serious complication. Sharp increase sugar causes damage to the nervous system, disruption of the heart, jump blood pressure. As a result, these symptoms can cause fainting, loss of normal reflexes, ketoacidosis, and even coma.

The normal level of glucose in the blood is 5.0-6.5 mmol/l, and jumps above 12 can cause the rapid development of diseases of the eyes, kidneys, of cardio-vascular system, leg problems. But you should not quickly try to “bring down” high glycemia, since you can provoke even more severe complication– hypoglycemia.

In order to detect elevated blood sugar levels in time and prevent the level of 17, you need to be careful and not miss the following symptoms:

acute thirst and dry mouth;
unjustifiably frequent urge to urination;
lethargy, fast fatiguability, drowsiness;
irritability, imbalance;
headache and dizziness;
itchy dry skin and even mucous membranes;
shallow disturbing dream or insomnia;
numbness of the limbs, dilated veins in the legs, feeling of heaviness;
nausea and vomiting even on an empty stomach;
the appearance of yellowish spots and skin growths on the face.

These signs may indicate the onset of illness or increased glycemia, and you should definitely pay attention to them.

There can be many reasons for the appearance of such signs. Some are caused age-related changes, and some - by lifestyle, and others - by violation of diet and medication regimen. People at risk include:

elderly;
with a hereditary tendency to diabetes;
those who are overweight;
leading a sedentary lifestyle;
susceptible constant stress those experiencing lack of sleep;
experiencing strong negative emotions– anger, rage – or depression and apathy;
not following a diet;
untimely administration of insulin or failure to correctly calculate the dosage of the drug;
dramatically lost or gained weight.

If blood sugar is 17 – what to do?

The most correct solution- call emergency assistance. This is very serious condition. In type 1 diabetes, a lactic acid or dehydrating coma may develop; in type 2 diabetes, deep fainting and disruption of the brain and heart function may develop. It is extremely dangerous to bring the disease to such a state; it is much easier to carry out prevention. Compliance simple tips will help prevent complications and maintain good health.

For supporting satisfactory condition necessary:

at infectious diseases and colds should be treated immediately;
avoid freezing, burns, injuries;
thoroughly treat chronic diseases, avoid exacerbations;
strictly follow the nutritionist’s instructions;
to refuse from bad habits;
study available types sports, walk more in the fresh air;
Avoid hormonal and diuretic drugs.

How to lower blood sugar from 17 to normal at home

If your glucometer shows a reading of 17 or another high reading, your blood sugar levels need to be lowered. And so that normal indicators preserved for a long time.

To achieve the norm and maintain it, doctors provide a number of recommendations.

It is necessary to monitor your diet. To compile daily ration choose products with low or medium glycemic index. These include lean meat and fish, seafood, pumpkin, cabbage, fresh cucumbers, tomatoes, pumpkin, parsley and celery roots and greens, mushrooms, seeds, nuts, pears, apples, bananas, bran, lettuce leaves, onions and garlic, legumes, citrus fruits. Foods such as peanuts and almonds can regulate glycemia, but due to high calorie content they should be consumed little by little.

You will have to give up mayonnaise and sauces based on it, sour cream, fatty and fried foods, products made from wheat flour and premium flour, baked goods, sweets, sweet fruits, carbonated drinks, smoked meats and sausages. The daily portion of food should be divided not into 3 doses, but into 5-6.

Take medications and remedies on time to help fight the disease. One of the most effective is a decoction of aspen bark. It’s easy to prepare: 1 heaped tablespoon of chopped bark will require 500 ml of water. The mixture needs to be boiled for half an hour, left for 3 hours, and then strained. You need to take the decoction before meals - for a minute or so. Also effective means Red beans and garlic oil are considered to help fight the disease.

Give the body reasonable physical activity, which will improve general state, get rid of excess weight and reduce glycemia.

If these conditions are met, you will not have to worry about spikes in your sugar levels.

Sugar more than 20

Diabetes requires constant glucose monitoring. A critical blood sugar level is the start of the development of irreversible processes in the human body. Short-term increases are dangerous due to immediate complications, and long-term critical glucose levels lead to damage to blood vessels and organs. It is important to know what is normal and what sugar level is considered critical.

Sugar norm

In a healthy body, the blood glucose level (fasting) should not be higher than 3.5-5.5 mmol. After eating, the value increases and should not exceed 7.8 mmol. These indicators are the generally established medical level for blood materials taken from a finger. For venous blood, the permissible level will be higher - 6.1 mmol on an empty stomach, but it is also considered normal.

The maximum sugar level for diabetes should be no more than the amount when glucose is excreted in the urine. 8-11 mmol is considered a slight increase, blood sugar 17 is a moderate condition, blood sugar 26 is a severe stage of hypoglycemia. Increased sugar in the blood negatively affects the functionality of the body, leading to irreversible, serious disorders. Blood sugar levels, according to age characteristics, are shown in the table.

Dangerous level

A reading of 18 mmol/l is already considered a complication. And blood sugar of 20 mmol/l and above provokes the development of irreversible pathologies that have a bad effect on human health. But it would be wrong to equate this indicator to all people. For some, irreversible consequences begin at 15 mmol, while others do not feel any disturbances, even if the sugar is 30 mmol. It is difficult to unambiguously determine the overall fatal level of sugar in the blood; each person has the highest individual level, taking into account their general well-being.

Causes and symptoms of increase

Diabetes is not the only cause of sudden increases in sugar levels. Stress, anxiety, pregnancy, and various diseases can increase glucose levels. Deviations from the norm are associated with disturbances in the processing of carbohydrates. In this regard, doctors have identified several main reasons that can briefly raise sugar to 20 units or more:

poor nutrition;
sedentary lifestyle;
temperature increase;
pain syndrome;
smoking and alcohol;
uncontrolled emotions.

Health disorders associated with pathological changes in the functionality of internal organs cause a persistent level of glucose. They are divided into groups depending on which organ is damaged:

organs of the gastrointestinal tract;
liver;
endocrine glands;
hormonal imbalance.

To reduce the indicator, you need to find out the reason for the increase and remove it.

Symptoms

It is possible to determine the exact indicator by examining blood taken on an empty stomach. Constantly high sugar in a person negatively affects a person’s well-being, causing characteristic symptoms:

prostration;
lethargy;
feeling of numbness in the limbs;
increased appetite;
constant thirst;
frequent urination;
persistent weight loss;
skin itching and rashes;
poorly healing wounds;
decreased sexual desire.
