Glucose Monitoring in Treatment of Postprandial Hypoglycemia After Gastric Bypass Surgery
- Conditions
- Hypoglycemia Non-DiabeticGastric Bypass Surgery
- Registration Number
- NCT06468865
- Lead Sponsor
- Sykehuset i Vestfold HF
- Brief Summary
The goal of this clinical trial is to learn if continuous glucose monitoring works to treat postprandial hypoglycaemia in patients who have undergone gastric bypass surgery. The main question it aims to answer is:
• Is continuous glucose monitoring superior to usual care for prevention of postprandial hypoglycaemia in patients with verified postprandial hypoglycaemia after gastric bypass surgery?
Researchers will compare continuous glucose monitoring to usual care to see if continuous glucose monitoring works to treat postprandial hypoglycaemia.
Participants will:
* Use a continuous glucose monitor for 6 weeks or use no continuous glucose monitor for 5 weeks and wear a blinded continuous glucose monitor for 1 week.
* Visit the clinic 2-3 times and have 2-3 phone consultations.
* Register symptoms of hypoglycaemia, answer questionnaires, undergo a 24-hour dietary recall interview conducted by a registered dietitian, measure weight and body composition and take blood samples.

- Primary Outcome Measures
Name Time Method • Difference between the two treatment arms in change in weekly diurnal time spent with hypoglycaemia (interstitial glucose <3.0 mmol/L) from the screening week to week 6, measured with a continuous glucose monitor. Screening (week 0) and week 6 Interstitial glucose is measured for one week during the screening week and for one week during week 6.
- Secondary Outcome Measures
Name Time Method • Difference between the two treatment arms in change in weekly diurnal time spent with hypoglycaemia (interstitial glucose <3.9 mmol/L) from the screening week to week 6, measured with a continuous glucose monitor. Screening (week 0) and week 6 Interstitial glucose is measured for one week during the screening week and one week during week 6.
• Difference between the two treatment arms in change in weekly time (total and nocturnal) spent with hypoglycaemia (interstitial glucose <3.0 mmol/L and <3.9 mmol/L) from the screening week to week 6, measured with a continuous glucose monitor. Screening (week 0) and week 6 Interstitial glucose is measured for one week during the screening week and one week during week 6.
• Difference between the two treatment arms in change in weekly events (diurnal, total and nocturnal) of hypoglycaemia (interstitial glucose <3.0 mmol/L and <3.9 mmol/L) from the sceening week to week 6, measured with a continuous glucose monitor. Screening (week 0) and week 6 Interstitial glucose is measured for one week during the screening week and one week during week 6.
