How does the blood sugar level change during the day, and what is the norm for a healthy person and a diabetic?

It has long been known that people with a diagnosis of diabetes are concerned about the daily measurement of blood sugar levels. This procedure is vital for them.

In addition, there are people who have a predisposition to "sweet disease." They also need to keep track of blood sugar.

This will prevent the disease in a timely manner, to prevent its development. The rate of sugar during the day should not exceed the long-established values. If it is higher than it should be, this indicates diabetes, or a condition that precedes the onset of a serious illness.

How does blood sugar level change during the day?

Back in the middle of the 20th century, scientists conducted mass experiments. They pursued two goals - to establish the rate of sugar in a person without pathologies, in a patient suffering from diabetes.

The experiment involved thousands of adults of different sexes, they just had to pass certain tests. There are three types:

  1. measuring sugar levels in the morning on an empty stomach;
  2. a study that was carried out 2 hours after eating food;
  3. determining the amount of glycated hemoglobin.

The standard rate of blood sugar is recognized as a criterion independent of the age and gender of the person.

From the list above, it is easy to make a definite conclusion. The sugar content in the blood depends on the composition of the ingested food.

For a healthy person, it is considered normal when the value rises by 2.8 units after eating. But there are other criteria, they are quite a lot.

Norm sugar during the day in a healthy person and diabetic

Why control glucose if you feel good? Many people think so, but once all diabetics were healthy. It is important not to miss the onset of the disease, prevent it from controlling your body and even life.

The following blood glucose criteria are established for a healthy person:

  • on an empty stomach, in the morning from 3.5 to 5.5 units;
  • before lunch, before dinner - from 3.8 to 6.1 units;
  • an hour after eating - less than 8.9 units;
  • 2 hours after meals - less than 6.7 units;
  • at night - less than 3.9 units.

A normal indicator of sugar for a healthy adult is 5.5 units.

When this value is exceeded for a certain time (several days), it is worth referring to an endocrinologist. The doctor should order a test that will make it easy to find out if there is any cause for concern. Sometimes a pre-diabetic condition is detected in this way.

But all individually, sugar can increase other reasons. This happens in women, this indicator often exceeds the norm after childbirth (undoubtedly, which is a great stress for the body) or during pregnancy.

Alcohol should not be consumed before testing.

Clinical research should be approached with the utmost seriousness. There are special rules, they will have to be observed, because an accurate result is important. Alcohol is not permitted.

Already a day you need to stop eating sweets. The last meal is allowed at 6 pm. Before donating blood, you can drink only drinking water. However, it can also have a negative impact on the results.

Sometimes studies reveal a low sugar level. This is evidence of abnormalities in the body. Most often in this way, problems with the thyroid, the digestive system. Sometimes it is a sign of cirrhosis.

For diabetics, doctors set other standards:

  • in the morning, on an empty stomach, the blood sugar level is from 5 to 7.2 units;
  • after eating for two hours - less than 10 units.

In a hungry person, the sugar indicators are at the minimum level. After a meal, blood glucose will be much higher. Normally, 2 hours after a meal, sugar should be absorbed.

A completely different picture is observed in diabetics - their pancreas with the production of a sufficient portion of insulin can no longer cope. Sugar is not digested.

Diabetes suffers from the condition of many internal organs - the kidneys, the nervous system, drops eyesight.

What can affect the measurement results?

Sometimes a completely healthy person suddenly increases sugar levels. When it’s not a pre-diabetic condition that the doctor will reveal with the help of a study, you should seriously think about lifestyle.

The level of glucose in the blood is affected by alcohol consumption, smoking, nerve shocks, hormonal medication.

Reasonable people in such cases quickly reconsider their attitude to life - get rid of bad habits, go in for sports.

Constant stress at work also does not benefit, if the increase in blood sugar is associated with this, it is worthwhile to find a quieter position for yourself.

How many times a day is it necessary to measure the level of glucose?

Diabetic novice will have to study your body again. He will need to determine at which jobs the sugar rises significantly. This will allow in the future to avoid critical conditions.

Check glucose level is needed:

  1. immediately after a night's sleep;
  2. before breakfast;
  3. two hours after the 1st meal;
  4. after 5 hours, if insulin injection was previously taken;
  5. before bedtime;
  6. when performing work associated with the risk of driving a car, the glycemic level should be measured every hour;
  7. under stress, slight hunger, work at work;
  8. during insomnia.

The life of a diabetic directly depends on the level of glucose. For this reason, this indicator should be kept under control.

Rules for using the meter at home

Recently, the life of diabetics has changed for the better. They can make their own sugar measurements using a glucometer.

It cannot be said that the results of independent research are unambiguous. But the ability to measure glycemia without visiting the lab is impressive.

Our fathers, grandfathers suffering from diabetes, dreamed of such a device. However, they need to use skillfully, in strict compliance with all regulations. The blood is taken from the finger.

In the course they go all the fingers (alternately), except for two - index, large. Any drop of moisture on the hands should be eliminated before the start of the study. This is necessary to obtain a reliable result.

It is not recommended to pierce the fingertip deeply, they do it not in the center, a little to the side. The blood is then applied to the strip tester, but it all depends on the model of the device. The result will be displayed on the screen, it takes just a few moments.
