NCT ID NCT06355154
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at whether a moderate carbohydrate diet (up to 120g per day) can help pregnant women with diabetes who need insulin achieve better blood sugar control compared to the standard high-carb diet. The trial will include 120 pregnant women and track their glucose levels and pregnancy outcomes. The goal is to find a safer, more effective diet for managing diabetes during pregnancy.
