My son was born five weeks prematurely had a low blood sugar for about six days before it was stabilized. Are there any long-term effects from this problem?
Low blood sugar in newborns is actually fairly common. In many instances, it is transient, meaning that the blood sugar level is found to be low in the period right after a baby is born but resolves relatively soon thereafter. In some infants, however, the low blood sugar levels can persist for longer periods, as was the case for your baby. This is also not uncommon in preterm infants. While it's impossible to answer your question about long-term effects more specifically without being familiar with the more detailed circumstances surrounding your baby's birth, I can tell you that it's not clear whether there are long-term consequences for premature babies who have low blood sugars without any other symptoms.
I encourage you to raise this question with your baby's doctor, who should have the necessary additional information and be happy to reassure you and/or address any lingering concerns you may have. In the meantime, I hope that new motherthood is treating you well now that your son has made his early entrance into the world.
