An interventional study of Can i3 Continuous Glucose Monitoring System in Dumping Syndrome and Post-bariatric Hypoglycemia, sponsored by Kaiser Clinic and Hospital. Recruiting at 1 site in Brazil. Open to participants aged 18 Years to 65 Years. Per ClinicalTrials.gov, last updated 2026-02-27.
Sponsored by Kaiser Clinic and Hospital · Not applicable, Interventional, and Supportive care
Late dumping syndrome is a common complication following Roux-en-Y gastric bypass, characterized by postprandial hypoglycemia with significant impact on patient safety and quality of life. Traditional capillary glucose monitoring has limited ability to detect rapid glycemic fluctuations.
This prospective randomized study aims to evaluate the efficacy and safety of the iCan i3 continuous glucose monitoring (CGM) system compared to conventional capillary glucose monitoring in detecting hypoglycemic events in post-bariatric patients with late dumping syndrome.
Participants will be randomized into two groups: one using CGM and one using standard fingerstick monitoring, and followed for 60 days. Clinical outcomes, hypoglycemia frequency, symptom correlation, and quality of life will be assessed.
This is a prospective, single-center, randomized, open-label clinical study evaluating the performance of a continuous glucose monitoring system (iCan i3) compared to conventional capillary glucose monitoring in post-bariatric patients diagnosed with late dumping syndrome.
Sixty participants will be randomly assigned (1:1) to either continuous glucose monitoring or capillary glucose monitoring for a period of 60 days. Data collected will include glycemic variability, hypoglycemic episodes, symptom correlation, and patient-reported outcomes such as fear of hypoglycemia (HFS-II) and quality of life (SF-36).
Continuous glucose data will be recorded every 3 minutes in the intervention group, while the control group will perform up to three capillary measurements per day based on symptoms.

Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.
An allergy, or another reaction of the immune system, to a substance. “Hypersensitivity to the study drug” means a known allergic reaction to it — not every side effect a medicine can have.
Malignancy means cancer. Criteria about another or earlier malignancy ask whether you have had a different cancer, usually within a set number of years.
Some are commonly allowed, such as treated skin cancers other than melanoma and early cancers removed completely — check the exceptions this study lists.

Continuous Glucose Monitoring (iCan i3)
Device: Can i3 Continuous Glucose Monitoring System
Capillary Glucose Monitoring (fingerstick using glucometer)
Device: Can i3 Continuous Glucose Monitoring System
Intervention 1 - Experimental Arm Device: iCan i3 Continuous Glucose Monitoring System Participants assigned to the experimental group will use the iCan i3 continuous glucose monitoring (CGM) system for 60 days. The sensor will be inserted in the abdominal region and will provide real-time interstitial glucose readings every 3 minutes via Bluetooth connection to a mobile application. Sensors will be replaced every 15 days, totaling four cycles during the study period. Data will be continuously recorded and stored for subsequent analysis. Participants will also record hypoglycemic symptoms and meal timing in a study diary. Intervention 2 - Active Comparator Arm Device: Capillary Glucose Monitoring (Glucometer - Sinocare) Participants assigned to the control group will perform capillary blood glucose monitoring using a glucometer (Sinocare). Measurements will be performed up to three times per day, preferably in the presence of hypoglycemic symptoms, using fingerstick sampling with
Frequency of hypoglycemic episodes (<70 mg/dL)
Mean number of hypoglycemic episodes per participant, defined as glucose levels \<70 mg/dL, measured using continuous glucose monitoring or capillary glucose monitoring over the study period.
Time frame: 60 days
Time Spent in Hypoglycemia
Percentage of time with glucose levels below 70 mg/dL, assessed continuously in the CGM group and estimated based on recorded measurements in the capillary monitoring group.
Time frame: 60 days
Clinical Severity of Hypoglycemic Events
Proportion of hypoglycemic episodes classified as mild (self-managed) or severe (requiring external assistance), based on participant-reported symptoms and clinical evaluation.
Time frame: 60 days
