Analysis of hidden sugar during pregnancy

In the third trimester, pregnant women must pass several mandatory tests, one of which is an analysis or test for glucose tolerance (TSH). This laboratory test is prescribed for all women at the age of twenty-eight weeks.

Why do you need it

This analysis is necessary, and this is due to the fact that recently there have been increasing incidences of gestational diabetes in the third trimester of pregnancy. This is a late complication and is on par with late toxicosis or preeclampsia.

When a woman gets registered and information is collected and her state of health is concerned, such an analysis may have to be taken much earlier, at the very beginning of pregnancy. If the result is positive, then the woman will be monitored during the entire pregnancy, she will have to follow all the medical recommendations to control her blood glucose level.

There is a risk group, which includes women who pay attention when registering in the first place. Criteria for which women during pregnancy fall into this group:

  1. Hereditary predisposition to diabetes mellitus (that is, the disease is congenital, but not acquired).
  2. The presence of excess body weight or obesity in a pregnant woman.
  3. There have been cases of stillbirth or miscarriage.
  4. The birth of a large child (weighing more than four kilograms) in the last birth.
  5. Chronic infectious diseases of the urinary tract and late gestosis.
  6. Pregnancy occurring after the age of thirty-five.

Women who are not on this list should be tested for glucose tolerance during pregnancy only in the third trimester, for a period of twenty-eight weeks.

What is missing glucose

Glucose is involved in the control of carbohydrate metabolism in the body, the balance of which begins to change with the onset of pregnancy.

Glucose is the main source of energy, which is necessary both for mom’s body and for the development of the baby. The sugar level is regulated by a specific hormone insulin, which is synthesized in special cells of the pancreas.

It promotes the absorption of glucose, thereby regulating its content in the blood. If this process deviates from the norm, then various diseases begin to develop, which the pregnant woman does not need at all. Therefore, on the eve of imminent labor, it is simply necessary to control the level of glucose.

A woman herself can correct carbohydrate metabolism and reduce the risk of its violation, if she carefully monitors her diet, then this analysis will reveal during pregnancy.

If the analysis during pregnancy gave a positive result, then re-test with increasing load. Repetition can be done three times. If a persistent increase in blood sugar is maintained, then a pregnant woman is put on a special diet, and each day she herself should measure glucose twice.

Pregnancy diabetes does not affect the development of a child, and usually after birth all carbohydrate metabolism processes return to normal, but many women are concerned about whether diabetes mellitus is inherited.

Preparation for the test and its conduct

To get the correct results of the analysis, you need to understand how the testing procedure goes and how to pass the test. Many doctors do not bring to the notice of pregnant features of the analysis.

Another name for TSH research is hourly, 2-hour, and 3-hour test. They are in full compliance with their names, so a woman should be prepared for the fact that she will have to spend quite a long time in the hospital. She can take a book with her or come up with another lesson during the waiting period and warn at work that she is late.

You need to take glucose with you for testing and clean water without gas. Directing for analysis, the doctor must say exactly which test will need to be passed and how much glucose must be diluted and drunk for the procedure.

If the test is hourly, then take 50 g of glucose, for 2 hours its amount is 75 g, for three hours – 100 g. Glucose must be diluted in 300 ml of mineral water without gas or boiled water. Not everyone can drink such sweet water on an empty stomach, so a small amount of citric acid or lemon juice is allowed to be added to the drink.

The test should be taken only on an empty stomach; eight hours prior to the procedure, one should not eat or drink anything other than water. Within three days before testing, you need to follow a special diet, while large portions of food should be excluded, it is necessary to limit the consumption of fatty, sweet and spicy foods.

On the eve of testing, one should also not overeat, but it is not recommended to starve and limit oneself too much in food, as this may adversely affect the test results.

The health of a pregnant woman and an unborn child depends on the correctness of the results of the study, so no need to artificially bring the result to normal by removing carbohydrates from the diet a few days before the test or, for example, drinking a smaller amount of glucose solution.

Analysis of hidden sugar during pregnancy

In the laboratory, you will need to fast on blood from a vein or finger (usually in all laboratories they take blood from a finger). After that, the woman must immediately take a glucose solution and after one, two or three hours to donate blood again. Time depends on the test assigned to it.

While waiting for a second blood sample, the following rules must be observed:

  1. A woman should be at rest, you can not use physical exertion and walk.
  2. It will be good if she manages to lie down, read a book.
  3. It is important during the analysis not to eat, you can drink only boiled or mineral water without gas.

Exercise will lead to increased energy consumption by the body, which will lead to an artificially low blood glucose, and the results of the analysis will be incorrect.

Test results

If, according to the results of the study, at least one of the parameters exceeds the norm, then after one or two days it is necessary to retest. In case of confirmation of impaired glucose tolerance, a woman should consult an endocrinologist and follow all his recommendations.

If a gestational diabetes was diagnosed to a pregnant woman, then she needs to follow a certain diet, ensure adequate physical exertion and constantly check her blood glucose level.
