Understanding blood sugar levels in newborns is very important. Blood sugar, or glucose, gives energy to the body. Babies need the right amount of glucose to grow healthy. In this article, we will explore what normal blood sugar is for a newborn.
Normal Blood Sugar Levels
The normal blood sugar level for a newborn can change. It depends on their age and health. For most newborns, normal blood sugar levels range from:
- 40 to 60 mg/dL (milligrams per deciliter) right after birth.
- 50 to 100 mg/dL during the first few days of life.
These values are general guidelines. Each baby is unique. It is best to check with a doctor for exact numbers.
Factors Affecting Blood Sugar Levels
Several factors can affect a newborn’s blood sugar levels. Here are some important ones:
- Gestational Age: Babies born early (premature) may have lower levels.
- Birth Weight: Smaller babies may struggle with blood sugar control.
- Feeding Status: Babies fed breast milk often have better levels.
- Maternal Diabetes: Mothers with diabetes can affect their baby’s sugar levels.
- Maternal Preeclampsia: This condition can lead to low blood sugar in babies.

If a newborn has hypoglycemia, doctors will provide treatment. This might include feeding the baby more often. Sometimes, sugar is given through an IV.
