Hypoglycemia means low blood glucose (sugar). It's a condition in which the amount of blood glucose in the blood is lower than normal. During pregnancy, glucose is passed to the baby from the mother through the placenta.  Some of the glucose is stored in the placenta, and later in the baby's liver, heart and muscles.  These stores of glucose are important for supplying the baby's brain with energy during delivery and for nutrition after the baby is born. 

Babies who are more likely to develop hypoglycemia include:

  • Babies born to mothers with diabetes
  • Babies born too early or too small
  • Babies born with associated conditions
