Glucose tolerance test

Pregnant mothers who have done glucose tolerance tests know that they need to drink sugar water continuously, and sometimes they feel like vomiting after drinking it. Some pregnant mothers feel that they are thin, so why do they need to do a glucose tolerance test? Is it necessary for every pregnant woman to do a glucose tolerance test?

In fact, the glucose tolerance test is to check for diabetes in pregnant women during pregnancy, and the main thing is to check the blood sugar level. It is very common for women to develop diabetes during pregnancy. There are two situations. The first is that the woman has diabetes before pregnancy and has a cup pregnancy at the same time. This situation is what we often call diabetes combined with pregnancy. The second situation is the opposite. The blood sugar metabolism is normal before pregnancy, and blood sugar abnormalities appear during pregnancy. This is called gestational diabetes.

During pregnancy, there are many factors that cause abnormal blood sugar metabolism in women, but because many people's symptoms are relatively mild or even not felt, sometimes fasting blood sugar measurements are normal, so they do not pay much attention to it. But in fact, gestational diabetes has a variety of adverse effects on both pregnant women and fetuses. Therefore, glucose tolerance tests must be done to ensure early detection and early treatment.

How much is the glucose tolerance standard worth?

Normally, the blood sugar level rises rapidly within 1/2 to 1 hour after taking sugar, and returns to the fasting level after 2 hours. If it does not return to the normal level within 2 hours after taking sugar, and the urine sugar is positive, it means impaired glucose tolerance. The standard values ​​of glucose tolerance for 75 grams of OGCT are as follows: blood glucose ≤5.1mmol/L; 1-hour blood glucose level ≤10.0 mmol/L; 2-hour blood glucose level ≤8.5 mmol/L.

If the blood sugar level is close to 7.8-11.1 mmol/l 2 hours after taking sugar, it means that the body's glucose tolerance is reduced, in other words, the body's absorption and utilization of sugar is worse than normal people.
