Summary

This study compared continuous glucose monitoring (CGM) to the standard glucose challenge test for screening gestational diabetes in over 1,600 pregnant women. The goal was to see if CGM leads to better health outcomes for mothers and babies, such as fewer large babies or birth injuries. Participants wore a CGM device for several days instead of or alongside the usual blood sugar test.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance: continuous glucose monitor (CGM)
What this could lead to: If successful, CGM could become a better way to screen for gestational diabetes, leading to fewer birth complications and lower healthcare costs.
What could go wrong: This is a completed trial, but results may not apply to all populations or settings. CGM is more complex and costly than standard screening, which could limit widespread use.
