This reduces the concentration of glucose in the blood.After eating a meal, the level of the indicator increases, especially if it contains carbohydrates.
Sugar decreases over time, gradually reaches average values, that is, it changes throughout the day.Normal blood sugar levels after meals vary from person to person, but there are some averages.
Sugar level after meals
If the patient has relatives with diabetes mellitus or pancreatic diseases, he is at risk.It is important for him to undergo an examination with a stress test (determination of sugar after drinking a glucose solution).The patient should know how much sugar should increase after eating.
Table of blood sugar levels after meals, depending on the time elapsed.
| Time after eating | Glucose concentration, mmol/l |
|---|---|
| Fasting | 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, blood sugar levels in a healthy person return to normal;the body needs an additional source of energy.This is particularly important in cases of hypoglycemia, i.e. a reduced concentration of sugar in the blood.The patient must know what time he should have his next meal.
Reason for discrepancies
There are many reasons why sugar values differ from normal values.It is important for the doctor to identify why blood sugar increases after eating.If you only treat the symptom, the disease will return.
Nutritional factor
A person includes excessive amounts of sugar in their diet.If the patient eats fatty, fried and spicy foods, the situation becomes complicated

Nutritional factor
A person includes excessive amounts of sugar in their diet.If the patient eats fatty, fried and spicy foods, the situation becomes complicated.
Glucose binds to cholesterol, forming plaques.The risk of blockage of the vessel increases, causing necrosis (death) of the tissue or organ.
Obesity is a common complication of poor diet.The patient has a large amount of fatty deposits.
Physical inactivity
If the patient has a hereditary predisposition to hyperglycemia, the situation becomes complicated in the absence of an active lifestyle.The blood stagnates and glucose and cholesterol accumulate in certain areas of the vessels.
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 cells.With a single acute inflammation, slight blood sugar appears.If the process has become chronic, the indicator is largely overestimated.
If the inflammatory process does not affect the islets of Langerhans of the pancreas, the amount of sugar remains within normal limits.
Stress
In cases of intense stress, the body produces cortisol and adrenaline.As a result, heart rate increases, blood pressure rises, and additional glucose is produced.This last phenomenon is due to the fact that the body needs energy to defend itself.
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 its normal concentration in the blood (type 2).Glucose is not delivered to cells or cannot cross their membrane.The cells send a signal to the central nervous system about the lack of energy.In response, the liver produces glucagon, which further increases sugar levels.
Infectious and viral diseases
If a person has a predisposition to developing diabetes mellitus, hyperglycemia may develop when an infectious or viral agent enters the bloodstream.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, as the body requires additional energy to nourish the fetus.
During pregnancy, gestational diabetes or high blood sugar becomes common.
Why does blood sugar change after eating?
Once food enters the gastrointestinal tract, it is processed and absorbed.Nutrients enter the bloodstream.These include proteins, fats and carbohydrates.These indicators add up to the calorie content.
In response to an increase in sugar, insulin is produced.It is a hormone that delivers glucose to cells and transports it across their membrane.
Transporting sugar takes time.Some target organs are located in the distal (distant) parts of the body.The concentration of indicators decreases every hour as cells consume nutrients.
Blood sugar measurement methods
There are the following methods for measuring blood sugar:
- sampling of capillary (from a finger) or venous blood with subsequent determination of the indicator using laboratory devices,
- measurement using a glucometer, which pierces the skin and collects a minimum amount of capillary blood,
- the use of test strips on which blood flows after prick of the skin,
- non-invasive methods that work by determining the physical parameters of the patient (pressure, temperature), the use of electromagnetic and ultrasound data,
- continuous measurements of the indicator using monitoring devices, which change once every two weeks.
The dangers of low and high sugar levels
Low blood sugar is called hypoglycemia.Under these conditions, the cells do not receive enough glucose.It does not penetrate 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 there is an increase in blood glucose, this condition is called hyperglycemia.Characterized by an increase in blood sugar levels.It accumulates in blood plasma and inside cells.
If a patient has absent or insulin-resistant cells, blood sugar levels build up for this reason.This pathology is characterized by an increase in blood pressure and a risk of cardiovascular diseases, which can lead to necrosis of tissues or organs.
Treatment of hyperglycemia
To treat high blood sugar, a diet that reduces the flow of carbohydrates through the gastrointestinal tract is necessary.Therapy must be comprehensive.It includes medicines and folk remedies.
Drugs
To reduce blood sugar, it is necessary to increase its consumption by the cells.For this purpose, insulin analogues are used.The medication should be administered daily 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.The capsules are replaced at the expiration date.
If the action of insulin is not sufficient, drugs are added to enhance its effect.
Folk remedies
The first thing a diabetic should do is drink their daily amount of water.If consumed in an amount of at least 2 liters per day, the blood plasma becomes larger and the concentration of substances in it decreases.In other words, the blood thins.
Solutions of the following herbs help reduce blood sugar:
- chamomile,
- chicory,
- rosehip,
- bay leaf.
Garlic infusion and lemon juice are used.All these medicinal plants help reduce blood sugar and the risk of cardiovascular disease.
Treatment of hypoglycemia
Hypoglycemia is a condition in which blood sugar levels are low.The main reason is the nutritional factor, that is, insufficient intake of carbohydrates into the blood.These patients need to eat constantly and eat foods high in glucose (candy, chocolate).
Treatment must be carried out comprehensively.Medical and folk remedies are used.
Drugs
The main thing in the treatment of hypoglycemia is the constant consumption of foods containing a large amount of carbohydrates.Products are applied every 2-3 hours, this reduces the risk of a sharp decrease in sugar.
If a patient's blood sugar drops sharply, emergency measures should be taken.In a hospital setting, these patients receive a glucagon or dextrose solution.
Folk remedies
Folk remedies include herbs and berries that contain large amounts of sugar.A decoction of rosehip, black currant, yarrow, sea buckthorn, calendula and thyme is used.
They can be used separately or together.All of these plants contain large amounts 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 remedies.It is important for patients to know what the norm is after eating.This will allow you to control its level, prevent complications, excessive excesses or a decrease in blood sugar levels.It is important to see your doctor periodically to monitor the condition.
Diet
In case of hyperglycemia, it is necessary to reduce the body's carbohydrate load.To do this, completely eliminate sweets, chocolate, sweet fruits and pastries.
A diabetic must calculate the glycemic index of each meal, which in case of illness should not exceed 70 units.
If the patient suffers from hypoglycemia, food is consumed 6-7 times a day in small portions.This maintains a constant concentration of carbohydrates in the body.You must have sweets and chocolate with you;they are used if a person feels dizzy or unwell.
