Effect of Fiber Supplementation on the Need for Medication With Gestational Diabetes

Effect of Fiber Supplementation on the Need for Medication With Gestational Diabetes: A Randomized Controlled Trial

The hypotheses to be tested are 1) Fiber supplementation will decrease the need for medication in patients with gestational diabetes, and 2) Fiber supplementation will decrease adverse maternal and neonatal outcomes in these patients. In this study, the investigators will conduct a randomized controlled trial to limit bias in evaluating these hypotheses.

The study team proposes a randomized controlled trial of women with singleton pregnancies who present with a new diagnosis of diet-controlled gestational diabetes (previously referred to as GDMA1). The participants will be randomized to the intervention group (fiber supplementation) or control group (no fiber supplementation) in 1:1 fashion. The participant will be randomized by a number-generating computer software after recruitment at the new gestational diabetes education class.
