Mixed Results of Metformin Therapy for Gestational Diabetes

The “traditional“ Parkland management protocol for GDM included the immediate initiation of medical therapy for those with abnormal fasting blood sugar, in addition to another additional value, on the 3 hour GTT. These patients were automatically labeled as A2 GDM at time of diagnosis, rather than waiting the 1 to 2 weeks of nutritional/diet therapy. Does fasting hyperglycemia on the 100g GTT truly predict the need for subsequent medical therapy? In this episode, we will summarize new data on this subject from AJOG MFM published on February 17, 2024. Does immediate medical therapy after GDM diagnosis improve overall maternal/neonatal outcome? It’s a complicated answer, and we will review it in this episode.
