What is glucose tolerance test for pregnant women?

Pregnant women need to undergo a blood sugar screening during pregnancy. The so-called blood sugar screening is to determine whether the blood sugar of the pregnant woman is normal during pregnancy, whether she has a normal blood pressure pattern, what she should eat in terms of diet, and to prevent gestational diabetes. These must be done because only in this way can the health of the fetus be guaranteed and poisoning and premature birth be avoided.

To check for gestational diabetes.

Fasting oral glucose tolerance test (OGTT): There are no restrictions on the patient's diet and activities for at least 3 days before the test. The test is performed in the early morning. Venous blood is drawn after fasting for 12 hours to measure fasting blood sugar, and then 75 grams of glucose powder is dissolved in 300 ml of water and drunk within 5 minutes. The blood glucose concentration was measured at 1, 2, and 3 hours after taking sugar. Eating, drinking and smoking are prohibited during the entire examination period.

Abnormal glucose metabolism during pregnancy is a common complication of pregnancy, which is divided into two states: gestational diabetes mellitus (GDM) and gestational impaired glucose tolerance (GIGT).

GDM is gestational diabetes.

GIGT means that blood sugar levels change steadily in the early stages, but the test value is an intermediate or transitional state between normal and abnormal. In other words, it is an imperfectly healthy state.

However, gestational diabetes or abnormal sugar metabolism during pregnancy can be harmful to both the mother and the baby, and may cause miscarriage, gestational hypertension, infection, polyhydramnios, ketoacidosis, premature birth, etc., so mothers still need to pay attention!
