Limitations of Continuous Glucose Monitoring in the Pediatric Total Pancreatectomy With Islet Autotransplantation Population: Comparing Patient Experiences of the Dexcom and FreeStyle Libre Systems

Caregivers reported frequent false alarms on both systems. The frequency of false hypoglycemia with FreeStyle Libre was an unexpected limitation with an unclear cause. The inability to calibrate the FreeStyle Libre likely contributed to frequent sensor changes and supply depletion. The ability to recalibrate the Dexcom system may provide an advantage, but not for people taking HU. Knowledge of CGM limitations post-TPIAT can help individuals make informed decisions.
