Approximately two out of 1,000 newborn babies have low blood sugar. During pregnancy, glucose is passed to the baby from the mother through the placenta. Some of the glucose is stored as glycogen in the placenta, and later in the baby's liver, heart and muscles. These stores of sugar 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 diabetic mothers
- Small for gestational age or growth-restricted babies
- Premature babies, especially those with low birth weights
