Why Does Insulin Serve as First Line Medication for Gestational Diabetes When More Than Half the Values Exceed Fasting Ninety Five or One Hour Postprandial One Forty?

First line treatment for gestational diabetes consists of dietary modifications along with nutrition consultation and glucose monitoring in women who presented metabolically healthy prior to pregnancy. Targets include fasting values under ninety five and one hour postprandial values under one forty. Monitoring continues until more than half the values stay below targets.

The short interval between diagnosis at twenty eight weeks and delivery limits lifestyle intervention to roughly two weeks. Elevated values in the first week lead directly to medication rather than extended attempts at control through diet alone. Insulin functions as first line medication during pregnancy due to insufficient data on efficacy and safety for many other agents. Metformin qualifies as fairly safe in pregnancy and potentially helpful. Insulin delivers the most effectiveness along with strong safety data plus the best influence on improving neonatal outcomes.
