Gestational diabetes is diabetes that develops during pregnancy. If untreated, gestational diabetes can cause serious complications for your newborn. Babies of untreated mothers may grow too large (called macrosomia), increasing the risk of problems during birth, such as injuries to their shoulders and arms, and increasing your risk for requiring a cesarean section or other assistance during delivery (such as a forceps or vacuum delivery). Your baby may also experience a sudden, large drop in blood sugar after birth. Your newborn baby may also have a higher risk of developing jaundice and breathing problems.
