Pregnancy glucose tolerance test

Abnormal glucose tolerance during pregnancy will affect the development of the fetus, and abnormal glucose tolerance will also affect the gastrointestinal absorption of nutrients, so it is recommended that pregnant women should pay attention to the problem of glucose tolerance. For the test method of glucose tolerance, the blood sugar concentration should be measured through the Down syndrome screening method. If the blood sugar concentration is too high, you should drink more water to lower the blood concentration.

Glucose tolerance test precautions

There are some things to pay attention to before, during and after the glucose tolerance test. Let’s take a look at them together.

Things to note before a glucose tolerance test:

1. Eat normally 3 days before the test, no need to control diet. In the three days before the test, the carbohydrate intake (i.e. rice and pasta) should not be less than 150 grams. If the subjects deliberately reduce the amount of staple food, the test results will be inaccurate, leading to misdiagnosis.

2. Exercise appropriately, avoid excessive exercise, and keep your emotions stable: Exercise appropriately 3 days before the test and avoid strenuous exercise. However, strenuous exercise before the test can excite the sympathetic nerves and increase blood sugar. Infection, trauma, and drastic mood swings can all excite the sympathetic nerves and affect the results of glucose tolerance tests.

3. Be sure to fast: When doing the glucose tolerance test, the expectant mother must fast for 8 to 14 hours to truly reflect the fasting blood sugar level. For example, if you are doing a glucose tolerance test at 8 o'clock in the morning, it is best not to eat since 10 o'clock the night before. You can drink water, but not tea or coffee. The first fasting blood sample is used to measure the sugar level in the blood, called a basal test.

Things to note when doing a glucose tolerance test:

4. No eating during the test: No smoking, eating or drinking during the test. You can walk around a bit, but avoid strenuous exercise. In addition, expectant mothers do not need to be nervous and should not let their emotions fluctuate due to multiple blood draws. They should try their best to cooperate with medical staff in drawing blood samples each time.

5. Special circumstances: If symptoms such as pale complexion, nausea, or fainting occur during the examination, the test should be stopped. If the above symptoms appear 3-4 hours after taking sugar, it should be considered as reactive hypoglycemia. Blood should be drawn immediately to measure blood sugar and the patient should be allowed to eat. ...

When should the glucose tolerance test be done?

Previously, we have talked about the major fetal malformation screening. The best time for major fetal malformation screening is between 24 and 28 weeks of pregnancy, because the fetus is most clearly observed at this time. Major fetal malformation screening has requirements for the time of the examination.

Similarly, glucose tolerance tests also have certain time requirements. Currently, Chinese hospitals generally use the Ministry of Health's industry standards for the diagnosis of gestational diabetes, that is, for expectant mothers with normal fasting blood sugar in the early pregnancy, it is recommended to undergo a formal 75g glucose tolerance test at 24-28 weeks of pregnancy to monitor blood sugar levels on an empty stomach and 1 hour and 2 hours after drinking sugar. If any one of the three items reaches or exceeds the limit value, that is, fasting blood sugar and blood sugar 1 hour and 2 hours after taking sugar are 5.1mmol/L, 10.0mmol/L, and 8.5mmol/L respectively, gestational diabetes can be diagnosed. It is not difficult to find that many examinations are conducted between 24 and 28 weeks, because this period of time is very important for both expectant mothers and fetuses. Because at this stage the fetus has been formed and various organs have developed, it is the best time to observe the fetus. Glucose tolerance testing is crucial for expectant mothers and babies. Therefore, expectant mothers should pay attention to glucose tolerance testing and pay attention to the best time for glucose tolerance testing.
