Blood Sugar Monitoring and Treatment in the NICU
Blood sugar is the amount of sugar in the blood. The body needs sugar to function. Blood sugar must stay within a certain range for the body to be healthy. A hormone (body chemical) called insulin helps the body maintain a normal blood sugar level. In many newborns, blood sugar is either too high or too low. So, doctors will carefully watch your baby’s blood sugar level during his or her stay in the neonatal intensive care unit (NICU). If your baby's blood sugar is too high or too low, treatment will bring it back under control.
Why Is My Baby’s Blood Sugar Abnormal?
Low blood sugar is common in many babies right after birth, as the baby’s body gets used to regulating its blood sugar level without help from the mother’s body.
High blood sugar can be caused by illness or stress. It’s also common in preemies born very early, because their pancreas (organ that makes insulin) is not fully developed.
How Blood Sugar Is Monitored
A health care provider uses a lancet (tiny blade) to take a drop of blood from your baby’s foot. The blood is put on a small test strip. This measures the sugar in the drop of blood.

How Blood Sugar Problems Are Treated
If blood sugar is too low, you may feed your baby more often. The natural sugar in your breast milk or formula helps raise blood sugar level. A health care provider may also give your baby supplemental glucose (sugar) through an IV (intravenous) line.
If blood sugar is too high, a health care provider may give your baby insulin. This helps the body use up more of the sugar in the blood. If the baby is being fed through an IV, a health care provider may also lower the amount of glucose in the IV fluid. However, babies need some sugar to grow and develop appropriately, so they cannot have all the glucose removed from their feeds.
Does My Baby Have Diabetes?
In adults, blood sugar problems are often due to diabetes. If a mother has diabetes, her baby is more likely to have temporary low blood sugar at birth. The problem continues until the baby’s pancreas adjusts to the baby’s normal blood sugar level. But the blood sugar problems your baby has does NOT mean your baby has diabetes. If your baby has low or high blood sugar as a newborn, it does not mean that your baby is likely to grow up to have diabetes, either.
