If the mother has no history of diabetes and the baby is of normal weight, the child’s blood glucose will return to normal within 3-6 hours after birth and the monitoring time will only last 24 hours. If the mother is diabetic or the baby is too large, the recovery time and monitoring time will be at least 3-5 days or even longer if the baby is not treated. Neonatal hypoglycemia often occurs in premature infants or in infants of diabetic mothers, where the mother’s pregnancy is accompanied by elevated blood glucose, which can raise the child’s blood glucose. High blood sugar in the mother may stimulate the fetus’s own pancreatic beta cells to secrete high levels of insulin. If the maternal supply is suddenly interrupted after the child is born, there may be relative hypoglycemia because the insulin level itself is not low. It is usually around 2-4 hours after birth that hypoglycemia starts to appear, and the child’s hypoglycemia performance is not particularly the same as that of adults, so the child must be given timely monitoring of blood sugar. If hypoglycemia is diagnosed, intravenous sugar supplementation should be given promptly and not delayed. Neonatal hypoglycemia is more common in neonatal hypoxia. The general damage to brain tissue depends on the severity and duration of hypoglycemia, so the baby should be treated promptly to avoid persistent hypoglycemia. Otherwise, it may lead to damage to the child’s brain cells and irreversible brain damage. Suggestions: Oral or intravenous infusion of glucose can be given to correct it, hormone therapy if necessary, and close monitoring of blood sugar. If the hypoglycemia can be corrected in time within 24 hours, it usually will not have too much effect on the baby.
