If the fetal condition is considered poor and continuation of the pregnancy is not considered safe, then delivery is considered. If delivery is recommended before 37 weeks gestation, your maternity care provider will consider maternal steroid injections and magnesium sulphate if less than 30 weeks to reduce the risk to the newborn of complications associated with prematurity. A newborn baby that has had trouble growing in the uterus may need to be cared for in the Neonatal Critical Care Unit depending on their prematurity, birth weight and how well they adapt to life outside the uterus.
Most fetuses that are shown to be large for gestational age on ultrasound are well nourished and healthy at birth. In some cases there is an underlying cause for the fetus to be large such as diabetes or a genetic syndrome. Some babies are larger due to maternal diabetes during pregnancy and in particular if maternal blood glucose levels have been difficult to control.
Larger babies born to mothers with diabetes are at increased risk of birth trauma including shoulder dystocia. When the fetus is suspected to be excessively large, induction of labour or caesarean section may be considered. When the mother has diabetes in pregnancy, their babies are also at risk of low blood sugar hypoglycaemia after birth as they no longer have access to the high sugar levels that they have become used to while in the uterus.
