Neonatal hypoglycemia is usually not related to the pregnant woman’s poor diet and tummy ache, it is related to the pregnant woman’s high blood sugar. Neonatal hypoglycemia is defined as a newborn’s blood glucose being lower than the normal neonatal minimum blood glucose value. Its diagnostic criterion is blood sugar less than 2.2mmol/l. If a pregnant woman’s stomach aches during pregnancy due to improper diet, this mainly causes gastrointestinal discomfort and has nothing to do with postpartum newborns having hypoglycemia. However, for some pregnant women with abnormal blood glucose, who have poor blood glucose control and high blood glucose before delivery, the newborn may have hypoglycemia. Hypoglycemic newborns are more dangerous, and should be breastfed early, see a doctor as soon as possible, and if necessary, some newborns need intravenous glucose.
