Continuous Glucose Monitoring in Metabolic Surgery

We will recruit 20 severely obese participants at Metamor Institute. Participants with obesity who are eligible for MBS will be randomized to either CGM group or self-monitoring of blood glucose (SMBG) group before the surgery based on a 1:1 ratio. All participants live in Baton Rouge, Louisiana. The surgeon in Metamor will introduce our study to the patients. If the patients are interested, the evaluation process includes verifying basic personal information, assessing health status and medical history, and evaluating specific eligibility criteria relevant to the study. The study coordinator will be discussing informed consent, ensuring participants understand the study's purpose, procedures, and any associated risks or benefits. Participants are encouraged to ask questions, ensuring clarity and comfort with the study. All collected data is documented and securely stored, respecting data privacy protocols. Eligible individuals are informed about the screening visit, while those not suitable are considered for future studies.
