Insulin vs. pills: which is safer for gestational diabetes?
NCT ID NCT07582471
First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study compared insulin injections and metformin pills in 60 pregnant women with gestational diabetes to see which is safer and more effective. Participants were randomly assigned to receive either insulin or metformin, and researchers monitored blood sugar levels and newborn health. The goal is to find the best treatment to prevent complications for both mother and baby.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Insulin (Humulin R) and metformin
- What this could lead to
- If successful, this could help doctors choose the safer and more effective medication for managing gestational diabetes, reducing risks for both mother and baby.
- What could go wrong
- This is a small, completed study with only 60 participants, so results may not apply to all pregnant women. Both treatments have known risks, and the study does not guarantee long-term benefits.
