Effect of Fiber Supplementation on the Need for Medication With Gestational Diabetes
What this study is about
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 randomly assigned controlled trial to limit bias in evaluating these hypotheses.

Interventions
DIETARY_SUPPLEMENT
Fiber
Psyllium fiber supplement capsules, 2g soluble fiber per capsule. They will be instructed to take 4 capsules twice daily for a total of 16g supplemental soluble fiber per day. This will be continued throughout pregnancy.
Primary outcome measures
Number of Participants with Need for GDM Medication
Time frame: From date of randomization until the date of first documented progression (assessed up to 7 months)
The primary outcome is the need for medication (either insulin or oral hypoglycemic agents) for management of gestational diabetes (progression from GDMA1 to GDMA2). We chose this primary outcome because the need for medication is associated with the need for significantly more antenatal interventions due to increased adverse pregnancy outcomes.

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
