Is this trial a fit for you?

Likely a good fit

Ideal candidates include pregnant women over 18 years old with singleton pregnancies who are on intensive insulin treatment for diabetes.

Probably not a fit

Patients with risk factors for placental insufficiency, hypertension, renal disease, or a history of preeclampsia may not benefit from this study.

What this trial studies

This clinical trial investigates the impact of a moderate carbohydrate diet (≤120g/day) compared to the standard care diet (≥175g/day) on glycemic control and metabolic outcomes in pregnant women with insulin-treated diabetes. The study aims to determine if the moderate carbohydrate approach can improve glycemic balance and alter metabolomic profiles, potentially leading to better pregnancy outcomes. Participants will be monitored using continuous glucose monitoring systems to assess their metabolic responses throughout the trial.

Why it matters

Potential benefit: If successful, this study could lead to improved glycemic control and reduced complications for pregnant women with diabetes.

How similar studies have gone: While some studies have explored carbohydrate restriction during pregnancy, this specific approach is relatively novel and has not been extensively tested.
