Could a simple wearable replace the glucose test after pregnancy?
NCT ID NCT07174245
First seen Jun 26, 2026 · Last updated Jul 09, 2026 · Updated 2 times
Summary
This study looks at whether continuous glucose monitors (CGMs) worn during late pregnancy and for two weeks after birth can predict which women with gestational diabetes will have abnormal blood sugar after delivery. Currently, only a small percentage of women complete the standard glucose test after pregnancy. The goal is to find a more convenient way to identify those who need follow-up care. The study will enroll 40 women and compare CGM data to the standard oral glucose tolerance 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, this could lead to a simpler, more accessible way to screen for postpartum blood sugar problems in women with gestational diabetes.
- What could go wrong
- This is a small, early-stage study (40 participants) focused on observation, not treatment. The findings may not apply to all women or change current screening guidelines.
