Low Blood Sugar in Newborns
Hypoglycemia & Breastfeeding
Breastfeeding the baby with low blood sugar.
Is low blood sugar in newborns serious? It is actually common for babies to have low blood sugar after birth, but breastfeeding
early and often can prevent and help with low blood sugar in a baby.
When a baby has low blood sugar, it does not mean that he will develop
diabetes; most of the time, the blood sugar levels will normalize after the baby starts to drink well.
The low blood sugar is treated immediately, because if it is left
for too long it can cause other serious problems like brain damage.
Causes of Low Blood Sugar in Newborns
- While a baby is inside his/her mother, his blood sugar is
controlled by hers, via the umbilical cord. The baby will then store some
glycogen in his/her liver during the last three months in utero. This is why
low blood sugar is more common in premature babies, due to the fact that they do not yet have the stored glycogen in their liver for regulating sugar.
- Another reason why a baby might have low blood sugar, is when the mother has
diabetes that is poorly managed. This will cause a baby to produce too
much insulin after birth.
- The baby may be too cold, stressed out or might cry too much after birth, which can also cause hypoglycemia.
- A baby born with low blood sugar may be producing too little glucose, which can be caused by brain injury or metabolic problems. This is a
very rare occurrence.
Babies that are at Higher Risk of developing Hypoglycemia
- low blood sugar in newborn babies is most commonly found when the mother has diabetes.
- Babies who are premature or who are a very low birth weight are at higher risk.
- A smaller twin has a higher risk of becoming a low blood sugar baby.
- Babies with colds or respiratory problems after birth.
- Mothers who had long labors.
- Babies who are under stress during delivery.
- Babies who get too cold after birth and are not allowed skin on skin contact.
- Mothers who are given intravenous fluids containing glucose.
Help your Baby and/or Prevent Low Blood Sugar in Newborns
- Breastfeed as often as you can. Breast milk will help stabilize a baby’s blood sugar levels.
- Keep your baby warm and prevent your baby from crying for long periods at a time
after birth. Skin to skin contact and kangaroo care is recommended.
- It’s best to breastfeed your baby as quickly after birth as
possible, even in the delivery room if you can.
- If your baby is not sucking properly, you can pump the colostrum and cup
feed your baby. Even a small amount of colostrum can help regulate your baby’s
- Breast compressions can increase the flow of milk and the amount of milk/colostrum that is transferred to a baby.
- If the mother is diabetic, she should eat well and control her diabetes properly during her pregnancy.
- If supplements or donated breast milk are given to a baby, make sure
that they are given without using artificial nipples, which can cause
There are many
alternative ways to feed a baby, including using a SNS; this allows a baby to stay on the breast while being supplemented.
Once feeding is established, newborn low blood sugar is usually not a problem anymore.
