About this trial
The goal of this randomized trial is determine if re-testing for gestational diabetes in the third trimester after an ultrasound measurement of estimated fetal weight (EFW) or abdominal circumference greater than 90%ile decreases cesarean delivery rate, and to evaluate the optimal method of re-testing. The main question it aims to answer is:
Does repeat testing for gestational diabetes and management of hyperglycemia decrease the cesarean delivery rate in fetuses measuring \>90%ile by estimated fetal weight (EFW) or abdominal circumference (AC) on ultrasound in the third trimester.
Participants will be randomized into two groups: Group 1 will undergo a repeat glucose tolerance test (GTT) with blinded continuous glucose monitor (CGM) and group 2 will have no intervention. Participants in group 1 will receive nutrition counseling as this would be standard in patients at high risk for gestational diabetes.
