Summary

The purpose of this study is to see if the use of a continuous glucose monitor (CGM) by people who experience low blood sugars (hypoglycemia) after gastric surgery can help reduce the number and severity of low blood sugar episodes.

Conditions

Interventions

DEVICE

Dexcom CGM masked

The CGM will monitor sensor glucose levels in all participants. (Initially the Dexcom G4 was worn by participants (n=13); however, when the G4 became unavailable, the G6 was worn by the subsequent participants (n=10)). The duration of the Dexcom G4 sensor was 7 days (2 sensors placed during each phase of participation) versus the Dexcom G6 whose sensor duration is 10 days (1 sensor placed during each phase of participation).

DEVICE

Dexcom CGM unmasked

During the second phase (2 weeks for the Dexcom G4 and 10 days for the Dexcom G6), participants are able to see the sensor glucose levels displayed from the CGM. Participants will be instructed to use this information to treat low glucose levels before symptoms or severely low glucose levels develop. The duration of the Dexcom G4 sensor was 7 days (2 sensors placed during each phase of participation) versus the Dexcom G6 whose sensor duration is 10 days (1 sensor placed during each phase of participation).
