Diabetes during pregnancy is generally referred to as gestational diabetes, and children born with normal blood sugar control during pregnancy are usually normal. However, if a pregnant woman with gestational diabetes does not have proper blood sugar control, the child she gives birth to may not be normal. Pregnant women with gestational diabetes, if the blood sugar control during pregnancy is normal, generally will not have an impact on the fetus, at this time most of the children born are normal. If the blood sugar of gestational diabetes is not controlled within the normal range, the child born may be abnormal, for example, the child may be born with neonatal respiratory distress syndrome, neonatal hyperbilirubinemia, neonatal hypoglycemia, neonatal erythrocytosis, hypocalcemia, hypomagnesemia and so on. Whether a child born to a pregnant woman with gestational diabetes is normal or not needs to be judged according to the pregnant woman’s blood glucose control and fetal development, and it is recommended that pregnant women need to bring their children to the doctor to check whether the development level is normal or not after delivery. In addition, pregnant women with gestational diabetes need to consult a doctor in a timely manner, under the guidance of the doctor to control blood sugar within normal levels.
