Patients with multiple pregnancies, a history of bariatric surgery, or those taking certain medications like metformin may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This study investigates whether pregnant women with a history of gestational diabetes (GDM) achieve better pregnancy outcomes through early blood glucose monitoring compared to traditional oral glucose tolerance testing later in pregnancy. Participants will be divided into two groups: one receiving continuous glucose monitoring early in pregnancy and the other undergoing testing at 28-32 weeks. The study will collect data on various pregnancy outcomes, including the need for labor induction and cesarean sections, to assess the effectiveness of early monitoring. Additionally, biological samples will be collected to explore underlying mechanisms related to GDM.

Why it matters

Potential benefit: If successful, this study could lead to improved pregnancy outcomes for women with a history of gestational diabetes.

How similar studies have gone: Other studies have shown promising results with early monitoring approaches, suggesting potential benefits in managing gestational diabetes.
