Fueling Labor: Protein Supplementation for Intrapartum Glucose Control
Sponsor: Medical College of Wisconsin
Summary
The goal of this study is to learn if high-protein drinks during labor can improve blood sugar control in pregnant women with insulin-treated diabetes. It will also help us learn if this approach is acceptable and well-tolerated by patients. The main questions it aims to answer are: * Does drinking high-protein beverages during labor keep blood sugar in a healthier range compared to drinking standard clear liquids? * How do participants feel about drinking protein beverages during labor, and does it affect their energy levels and birth experience? * Is the baby less likely to have low blood sugar after birth when the mother drinks protein beverages during labor? Researchers will compare women who drink high-protein beverages to women who drink standard clear liquids (like juice, broth, and popsicles) to see if protein drinks help keep blood sugar more stable during labor. Participants will: * Wear a small, painless glucose sensor on their arm from when labor starts until about one week after giving birth * Be randomly assigned to either drink a clear protein beverage every 4 hours during labor OR drink standard clear liquids as usual * Complete short surveys about how tired they feel during labor, their overall birth experience, and their overall experience with the glucose sensor

Interventions
High-Protein Beverage (Genius Gourmet Sparkling Protein Water)
Clear, carbonated, commercially available high-protein nutritional supplement containing approximately 30 g protein, 0 g carbohydrate, 0 g fat, and 130 kcal per 12-ounce serving. Offered every 4 hours during labor. Multiple flavors available (participant's choice).
Standard Clear Liquid Diet
Standard institutional clear liquid diet including water, ice chips, clear fruit juices (e.g., apple juice), clear carbonated beverages (e.g., ginger ale), popsicles, clear broth, and gelatin. Carbohydrate-containing clear liquids permitted per standard practice.
Continuous Glucose Monitoring (Abbott Freestyle Libre)
Abbott Freestyle Libre 2 or Libre 3 CGM sensor placed on upper arm upon admission. Sensor remains in place through delivery and up to 7 days postpartum. CGM data blinded to participants and clinical staff during labor.
