Why take a glucose tolerance test?
GTT, or "Sugar load" allows you to determine the doctors how well glucose is absorbed in the organism of the future parturient, and whether there is any pathology in this process. The fact is that the body of a woman with the development of pregnancy should produce more insulin, in order to successfully adjust the level of sugar in the blood. Approximately in 14% of cases this does not happen and the level of glucose rises, which not only negatively affects the development of the fetus, but also the health of the most pregnant. This condition is called "gestational diabetes" and if you do not take appropriate measures in time, then it can develop into type 2 diabetes.
Who needs to take GTT?
Currently, doctors identified a group of women at risk when a glucose tolerance test is necessary in pregnancy, and if you are in this number, you can understand the following list.
The GTT analysis is mandatory if:
- someone from close relatives of the future childbirth suffers from diabetes mellitus;
- there is a suspicion of bearing a large fetus or the previous pregnancy ended with childbirth weighing more than 4.5 kg;
- in the analysis of urine or blood, sugar was detected;
- in the previous pregnancy "gestational diabetes" developed;
- there is an excess weight when the index of body mass index exceeds 30.
How to prepare for the analysis?
If it happened that you were given a direction for a glucose tolerance test during pregnancy, then it is not necessary to panic before the time. Physicians have long been proven that this is one of the most "whimsical" analyzes, where even small disturbances on the eve can show a "false positive" result. In addition, when preparing for a glucose tolerance test during pregnancy, severe restrictions are imposed on food: food can not be taken 8-12 hours before the analysis begins. From drinks you can drink only non-carbonated water, but no later than 2 hours before the blood is given to it, too.
How to take a glucose tolerance test during pregnancy?
HTT is a fence of venous blood in the morning on an empty stomach. An oral glucose tolerance test during pregnancy is performed in the following stages:
- Taking venous blood and measuring the level of glucose in the blood.
If the laboratory worker finds a high glucose content: 5.1 mmol / L and higher, the future woman giving birth is diagnosed with "gestational diabetes" and the test ends there. If this does not happen, then go to the second stage.
- Use of a pregnant solution of glucose.
Within five minutes from the moment of blood sampling, the future mummy needs to drink a glucose solution, which she will be offered in the laboratory. Do not be afraid if its taste seems too luscious and unpleasant. To avoid a vomiting reflex it is necessary to stock up a lemon in order to squeeze into the solution the juice of this fruit. After all, as practice shows, in this form it is much easier to drink it.
- The fence of venous blood 1 and 2 hours after the use of the solution.
In order to correctly assess the level of glucose in the blood, its fence is made 1 hour after the use of the solution and after 2 hours. If the future mother does not have "gestational diabetes", the indicators will decrease.
The norm of the indicators for a glucose-tolerant test during pregnancy is as follows:
- less than 5.1 mmol / l for fasting blood on an empty stomach;
less than 10 mmol / l 1 hour after the consumption of glucose solution; - less than 8.5 mmol / L after 2 hours.
And finally, I want to draw attention to the fact that some future mothers refuse this test, considering it superfluous. However, it is worth noting that gestational diabetes is a very difficult disease, which can not give out anything substantial until the birth. Do not neglect them, because if you have it, then a special treatment and constant monitoring by the doctor will be prescribed, which is very important, because it is very important. will allow you to take out your crumb before the due date.
