Summary

This study tests whether starting nutritional counseling early in pregnancy can improve blood sugar control in women at risk for gestational diabetes. 150 pregnant women will receive either standard care or one-on-one sessions with a dietitian, plus videos and phone support. The goal is to see if early healthy eating habits can prevent or reduce diabetes-related complications.

What this could mean

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

Active substance
nutritional counseling and motivational interviews with a registered dietitian
What this could lead to
If it works, this could show that early dietary support helps prevent gestational diabetes in at-risk women.
What could go wrong
This is a small, early-stage trial (150 participants) testing a behavioral intervention, so results may not be conclusive or widely applicable.
