Drinking glucose mainly improves the blood glucose level of newborns, because many newborns can become hypoglycemic after birth due to various factors, and if the blood glucose level is less than 40 mg/dL which is 2.2 μmol/L, it can be diagnosed as hypoglycemia. Hypoglycemia in newborns can cause feeding difficulties, drowsiness, and light crying, and can even lead to convulsions. The above symptoms can occur after hypoglycemia, and can also lead to irreversible brain damage in newborns. It is important to raise the blood sugar level in time after the newborn has low blood sugar, and drinking glucose can quickly raise the blood sugar level.
