What this trial studies
This study investigates whether fiber supplementation can reduce the need for medication in women diagnosed with gestational diabetes mellitus (GDM). It is a randomized controlled trial where participants with singleton pregnancies and diet-controlled GDM will be assigned to either receive fiber supplements or not. The aim is to evaluate the effects of fiber on both medication requirements and maternal and neonatal health outcomes. Randomization will be conducted using a computer-generated number system to ensure unbiased results.
Why it matters
Potential benefit: If successful, this study could help reduce medication use and improve health outcomes for mothers and their babies during pregnancy.
How similar studies have gone: While the approach of using fiber supplementation in gestational diabetes is promising, it is relatively novel and has not been extensively tested in previous studies.
