What is a glucose tolerance test?

Glucose tolerance generally refers to oral glucose tolerance test, which is used to check whether there is gestational diabetes or abnormal glucose tolerance. A large number of studies show that the risk of preeclampsia, premature rupture of membranes, cesarean section and premature delivery in patients with gestational diabetes mellitus is obviously increased, and the risk of neonatal macrosomia is obviously increased. Gestational diabetes is also obviously related to fetal malformation. Therefore, all pregnant women are required to take one or two blood sugar measurements at 24-28 weeks.

Diabetes mellitus (GDM), which was first discovered or occurred after pregnancy, has an increasing trend, accounting for about 10% of all pregnant women. This is because during pregnancy, various factors will lead to abnormal glucose metabolism, but many people have no corresponding symptoms, and even fasting blood sugar is normal, so it has not attracted corresponding attention. However, gestational diabetes will have many adverse effects on pregnant women and fetuses. Therefore, it is best for pregnant women with conditions to do a sugar screening test to find out whether there is gestational diabetes as soon as possible and treat it in time.

Be sure to have an empty stomach on the day of examination. It is generally recommended that pregnant mothers do not eat or drink after 8 pm, and it is best to have an empty stomach interval of 10~ 14 hours, so that the effect will be relatively better. After arriving at the hospital, please queue up for a doctor's prescription and take 1 tube blood on an empty stomach. You can jump in line and tell the doctor that you are sugar-tolerant, and the general doctor will give priority.
