What effect does pregnant women not do glucose tolerance test during pregnancy have on the fetus?

At 2 1-24 weeks of pregnancy, a particularly important prenatal examination is glucose tolerance test. Some pregnant mothers may have such doubts. I don't have diabetes, and I don't like sweets. Do I have to do a glucose tolerance test? The answer is yes, because gestational diabetes can lead to fetal growth retardation and even termination of pregnancy.

What effect does pregnant women not do glucose tolerance test during pregnancy have on the fetus? 1. If the pregnant mother has no glucose tolerance, it is impossible to evaluate the blood sugar level and blood sugar content in the body, which will easily lead to the birth of a macrosomia, which is a threat to the natural delivery, and even prone to hypoglycemia and respiratory distress after birth.

2. If the pregnant mother has no glucose tolerance, she won't know whether she has gestational diabetes, and she won't control her diet and weight well. Gestational diabetes is easy to cause miscarriage, premature delivery and abortion.

3. If the pregnant mother has no glucose tolerance, she will not know that her body's utilization rate of glucose is declining, and it is easy to prolong the labor process due to uterine atony bleeding during delivery, and even threaten the safety of mother and baby.

Simply put, if diabetes is not well controlled, the maternal blood sugar level will enter the fetus through the placenta. Excessive blood sugar level can stimulate the secretion of fetal islets, cause fetal hyperinsulinemia, further promote the intake of amino acids by fetal cells, accelerate the synthesis of protein, and reduce the rate of fat decomposition, thus causing macrosomia. Although this fetus is heavy, it actually has many health problems, such as increased maternal oxygen consumption and easy hypoxia; Affected by hyperinsulinemia, it will also lead to delayed fetal lung maturity; Fetal distress and neonatal asphyxia are prone to occur during childbirth; Neonates are prone to respiratory distress, hypoglycemia and even convulsions after birth.

How is the glucose tolerance test done? Dissolve 50 grams of glucose powder in 200 ml of water and drink it within 5 minutes. Then blood samples were taken at 1 and 2 hours to measure blood sugar. If any of the three values reaches or exceeds the critical value, a 75g glucose tolerance test is needed to determine whether gestational diabetes exists.

This test is usually performed at 24 weeks of pregnancy. Before doing it, draw blood on an empty stomach for at least 8 hours. In other words, pregnant mothers should fast after dinner the day before the birth check-up. On the day of the exam, they can't eat or drink water before the exam begins.

Many pregnant mothers fail the glucose tolerance test for the first time. In fact, these pregnant mothers have no problems, but eating too many sweets the day before will make the sugar intake higher than the daily diet, which will affect the blood sugar value of pregnant mothers and lead to abnormal results. Therefore, in the first few days of the exam, the sugar intake should be properly controlled, but it should not be over-controlled, otherwise the real results will not be reflected.

Tips:

Glucose tolerance test takes a long time and needs to be carried out on an empty stomach, which is difficult for pregnant mothers. The prospective father should accompany him as much as possible, and then bring some snacks to prevent the pregnant mother from shaking and dizziness because she hasn't eaten for too long.

That's my answer. I hope every pregnant mother can actively have a check-up on time and do every check-up item well.
