Determining Efficacy of Continuous Glucose Monitoring to Reduce Hypoglycemia and Improve Safety after Gastric Surgery


The purpose of this study is to test if a continuous glucose monitor (CGM) can detect and help prevent hypoglycemia (low blood sugar) in individuals who have post-bariatric surgery hypoglycemia syndrome.

This study involves:

  • 3 to 5 visits to Joslin Diabetes Center over 4 weeks
  • Wearing a continuous glucose monitor and fitness tracker
  • Keeping a log of blood sugar levels, hypoglycemic symptoms, and treatment of symptoms
  • Keeping a food and activity log


You may qualify to participate if you are:

  • A male or female diagnosed with ongoing post-bariatric or post-gastric surgery hypoglycemia with prior episodes of neuroglycopenia (low blood sugars with neurological symptoms).
  • Ages 18-65 years.

Study staff will compensate you for the cost of parking or taxi services. At the completion of the study, you will be able to keep the continuous glucose monitor system, including receiver (good for indefinite use) and transmitter (duration of use 6 months).
