Glucose monitor could spot diabetes risk after pregnancy
NCT ID NCT07034261
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study will test whether a continuous glucose monitor (CGM) worn for 14 days after childbirth can predict which women with a history of gestational diabetes are at risk for developing type 2 diabetes. Fifty participants will wear a blinded CGM device and then take a standard oral glucose tolerance test 4-12 weeks after delivery. The goal is to see if the CGM data can replace or improve upon the standard test for detecting postpartum blood sugar problems.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Blinded Continuous Glucose Monitoring Device
- What this could lead to
- If successful, this could show that a simple 14-day glucose monitor can identify women at risk for type 2 diabetes after gestational diabetes, potentially leading to earlier detection and prevention.
- What could go wrong
- This is a small, early-stage study (50 participants) that is not yet recruiting. It only measures how well the monitor predicts results of a standard test, not whether it improves health outcomes. The device is blinded, so participants cannot see their own glucose levels during the study.
