Women will be recruited from one of two outpatient obstetric clinics, University of Florida (UF) Health Women's Center - Medical Plaza or UF Health Women's Center. Women presenting for scheduled cesarean section will be provided with an opportunity to participate. Then the women will be randomized into one of three groups: oral carbohydrate beverage (group CHO), re-hydration beverage of an equal volume (group R) or fasted controls (group F). All subjects who consent to participation will have the following recorded: height, weight, age, indication for cesarean section, surgeon, and number of prior cesarean sections.
