Can a 24-Hour patch after delivery predict future diabetes?
NCT ID NCT07449039
First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This pilot study is testing whether wearing a continuous glucose monitor (CGM) for just 24 hours after giving birth can help predict a woman's long-term risk of developing type 2 diabetes. The study involves 50 women who had gestational diabetes and will wear the CGM immediately after delivery. Researchers will compare the CGM data with standard tests to see if this quick, non-invasive method works as a screening tool.
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 (Dexcom G7)
- What this could lead to
- If successful, this could lead to a simple, immediate postpartum test to identify women at high risk for type 2 diabetes, enabling earlier prevention.
- What could go wrong
- This is a small pilot study with only 50 participants, so results may not apply to everyone. The 24-hour CGM may not accurately predict long-term diabetes risk compared to standard tests.
