Hypoglycemia In A Newborn: Causes, Symptoms & How To Treat It?

Hypoglycemia is a condition in which the blood sugar is abnormally low. Usually we come across adults having hypoglycemic episodes. However, it can occur in people of any age including the newborns. Hypoglycemia in newborn is more often seen in premature babies, low birth weight babies or baby born to mother having diabetes. There is less possibility of hypoglycemia in a healthy new born baby.

The condition in newborn is dangerous because it can impair brain function and in worst case can cause seizures. Treatment of hypoglycemia is individualized depending on the symptoms.

Feeding breast milk is the best option whenever possible. In some cases where glucose level is too low, glucose solution is administered intravenously.

What Causes Hypoglycemia In A Newborn?

The hormone insulin plays a vital role in balancing sugar in the blood. When this balance is disturbed, hypoglycemia occurs. Normally soon after birth, the sugar level may dip for few hours but after intake of breast milk, the level comes up. These ups and downs will make the baby hungry. Feeding breast milk to the baby will help in balancing the sugar level in blood.

However, some factors can cause too low blood sugar level in blood of newborn. They are:

  • Premature babies with low birth weight are at risk of developing hypoglycemia.
  • Small sized babies may have restricted glucose store in their body.
  • Mother suffering from diabetes during pregnancy.
  • Newborn with unstable body temperature.
  • Large sized baby for their gestational age. Most often it is associated with gestational diabetes.
  • Certain medicines taken by mother during her pregnancy can cause hypoglycemia in babies soon after birth.

  • Congenital birth defects.
  • Breathing problems during birth.
  • Infection
  • Hemolytic disease which occurs due to incompatibility of mother and baby’s blood.
