It reduces the concentration of glucose in the blood.The level of the indicator rises after a meal, especially if it contains carbohydrates.
Sugar decreases over time, gradually reaching average values, that is, it changes throughout the day.Normal postprandial blood sugar levels vary from person to person, but there are certain averages.
Sugar level after a meal
If relatives of the patient have diabetes mellitus or pancreatic diseases, he is at risk.It is important for him to undergo an examination with a stress test (sugar determination after drinking a glucose solution).The patient should know how much sugar should rise after eating.
Table of postprandial blood glucose levels as a function of elapsed time.
| Time after meal | Glucose concentration, mmol/l |
|---|---|
| On an empty stomach | 3.3-5.5 |
| 1 hour | 7.8-8.7 |
| 2 hours | 6.5-7.7 |
| 3 hours | 6-6.5 |
| 4 hours | 5.5-6 |
| 5 hours | 4-5.5 |
After 6 hours, the blood glucose value in a healthy person returns to normal;the body requires an additional source of energy.This is especially important in the case of hypoglycemia, that is, a decrease in the concentration of blood sugar.The patient should know when to take the next meal.
The reason for the deviations
There are many reasons why sugar indicators are different from normal values.It is important for the doctor to determine why glucose rises after a meal.If you only treat the symptom, the disease will reappear.
Nutrition factor
A person has an excessive amount of sugar in their diet.If the patient eats fatty, fried, spicy foods, the situation becomes more complicated

Nutrition factor
A person has an excessive amount of sugar in their diet.If the patient eats fatty, fried, spicy foods, the situation becomes more complicated.
Glucose combines with cholesterol to form plaques.The risk of blockage of the vessel increases, which leads to necrosis (death) of the tissue or organ.
A common complication of an unhealthy diet is obesity.The patient has a large amount of fat deposits.
Physical inactivity
If the patient has a hereditary tendency to hyperglycemia, the situation becomes more complicated in the absence of an active lifestyle.Blood stagnates and glucose and cholesterol accumulate in certain areas of the arteries.
Inflammatory diseases of the pancreas
When inflammatory processes occur in an organ, beta cells reduce insulin production.It is necessary for the delivery and passage of sugar into the cells.Mild glycemia appears with only acute inflammation.If the process has become chronic, the indicator is overestimated.
If the inflammatory process does not affect the islets of Langerhans of the pancreas, the amount of sugar remains within the normal range.
Stress
When severe stress occurs, the body produces cortisol and adrenaline.As a result, heart rate increases, blood pressure rises, and extra glucose is produced.The last phenomenon is related to the body's need for self-defense energy.
Diabetes mellitus
This is a disease that develops due to insufficient insulin production (type 1).
Another reason is the lack of function of the hormone at a normal concentration in the blood (type 2).Glucose is not delivered to cells or cannot pass through their membrane.Cells send a signal to the central nervous system about the lack of energy.In response, the liver produces glucagon, which further increases blood sugar levels.
Infectious and viral diseases
If a person has a tendency to develop diabetes mellitus, hyperglycemia can develop when an infectious or viral agent enters the blood.This reaction is a protective device in the fight against pathogenic microorganisms.
Pregnancy
When pregnancy occurs, the hormonal balance changes, and as the fetus grows, the pressure on the internal organs increases.Pregnancy is characterized by an increase in normal glucose values, because the body requires additional energy to feed the fetus.
Gestational diabetes or hyperglycemia becomes common during pregnancy.
Why does blood sugar change after eating?
After food enters the gastrointestinal tract, it is processed and absorbed.Nutrients enter the blood.These include proteins, fats and carbohydrates.These indicators increase the amount of calories.
Insulin is produced in response to increased sugar.It is a hormone that delivers glucose to cells and passes through their membrane.
It takes time to transport sugar.Some target organs are located in distal (distant) parts of the body.As cells consume nutrients, the concentration of indicators decreases every hour.
Blood sugar measurement methods
There are the following methods for measuring blood sugar:
- collection of capillary (from a finger) or venous blood with subsequent determination of the indicator using laboratory devices;
- measurement using a glucometer that pierces the skin and collects a minimal amount of capillary blood;
- the use of blood-drop test strips after skin puncture,
- non-invasive methods that work by determining the patient's physical parameters (pressure, temperature), the use of electromagnetic and ultrasound data,
- continuous measurement of the indicator using monitor devices that change once every two weeks.
Dangers of low and high sugar levels
Low blood sugar is called hypoglycemia.In this case, the cells do not receive enough glucose.It does not enter the brain, which leads to a decrease in the activity of the central nervous system, and there is no transmission of nerve impulses to organs and tissues.
If blood glucose increases, this condition is called hyperglycemia.It is characterized by an increase in blood sugar.It accumulates in the blood plasma and inside the cells.
If a patient does not have insulin-resistant cells, this is why blood sugar builds up.The condition is characterized by an increase in blood pressure and the risk of cardiovascular diseases, which can lead to necrosis of tissues or organs.
Treatment of hyperglycemia
To treat hyperglycemia, a diet that reduces the flow of carbohydrates into the gastrointestinal tract is necessary.Therapy should be comprehensive.This includes medicines and folk remedies.
Medicines
To reduce blood sugar, it is necessary to increase its consumption by cells.Insulin analogues are used for this purpose.The medicine should be taken every day after meals.
There are long-acting insulin preparations that are administered subcutaneously in the form of capsules.They produce a medicine that lasts a long time.Capsules are replaced after the expiration date.
If the effect of insulin is not enough, drugs that increase its effect are added.
Folk treatment
The first thing a diabetic should do is to drink the daily amount of water.If consumed in an amount of at least 2 liters per day, the blood plasma increases and the concentration of substances in it decreases.That is, the blood is diluted.
Solutions of the following herbs help lower blood sugar:
- chamomile,
- chicory,
- rose,
- bay leaf.
Garlic infusion and lemon juice are used.All these herbs help to reduce blood glucose levels and the risk of cardiovascular diseases.
Treatment of hypoglycemia
Hypoglycemia is a condition in which blood sugar levels are low.The main reason is the nutritional factor, i.e. insufficient absorption of carbohydrates into the blood.Such patients should constantly eat, eat foods containing high glucose (sweets, chocolate).
Treatment should be thorough.Medical and folk remedies are used.
Medicines
The main thing in the treatment of hypoglycemia is the constant consumption of foods with a large amount of carbohydrates.Products are applied every 2-3 hours, which reduces the risk of a sharp decrease in sugar.
If the patient's blood glucose drops sharply, urgent measures should be taken.Even in hospital conditions, patients are given glucagon or dextrose solution.
Folk treatment
Folk remedies include herbs and berries that contain a large amount of sugar.Decoction of rose hip, currant, yarrow, tea tree, calendula, thyme is used.
They can be used separately or together.All these plants contain a large amount of sugar and have the ability to accumulate in the body.That is, the concentration of the indicator remains stable for a long time and does not decrease.
Hyperglycemia and hypoglycemia are dangerous for the human body.If they are detected, you need to follow a diet, use medical and folk methods.It is important for patients to know what the norm is after eating.This will allow you to control its level, prevent complications, increase or decrease the level of glucose in the blood.It is important to consult a doctor periodically to monitor the disease.
Diet
In the case of hyperglycemia, it is necessary to reduce the carbohydrate load on the body.To do this, completely remove sweets, chocolates, sweet fruits and baked goods.
A diabetic patient should calculate the glycemic index for each meal, which should not exceed 70 units in case of illness.
If the patient experiences hypoglycemia, food is consumed in small portions 6-7 times a day.It maintains a stable concentration of carbohydrates in the body.You should have sweets and chocolate with you;used when a person feels dizzy or ill.
