Study Summary
This trial is comparing two different thresholds for when to start medical treatment for gestational diabetes mellitus (GDM). Pregnant women with GDM will be randomly assigned to start treatment when they reach at least 20% or 40% above the target goal for capillary blood glucose (CBG) levels. The investigators think that a lower threshold of 20% will lead to fewer obstetric and medical complications.
