Pregnant women with high blood glucose is not necessarily diabetes, because the diagnosis of gestational diabetes has a clear standard, this standard is the pregnant woman’s fasting blood glucose>5.1mmol/L, 1 hour after meal blood glucose>10mmol/L, or 2 hours after meal blood glucose>8.5mmol/L, as long as one of the three standards can be diagnosed as gestational diabetes, which refers to pregnant women in the OGTT, also known as oral glucose tolerance test after clear standards, so pregnant women perfect glucose tolerance test indicators do not reach one of the above three points, can only say that currently belongs to the pre-gestational diabetes. This refers to the pregnant woman after the OGTT, that is, oral glucose tolerance test clear standards, so pregnant women perfect glucose tolerance test indicators do not reach one of the three points above, can not be diagnosed as gestational diabetes, can only say that currently belongs to the stage of gestational pre-diabetes, this stage is called pre-diabetes rather than diabetes, the patient does not often need drug treatment. If the blood sugar has reached the diagnostic criteria, patients with gestational diabetes often need to receive insulin treatment to ensure stable blood sugar, which is more meaningful to both the mother and the fetus.
