Optimizing Glycemic Control in Metabolic Surgery With Continuous Glucose Monitoring
Pennington Biomedical Research Center
Summary
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.
Description
Obesity is listed as the most important risk factor associated with organ dysfunctions. More than 42% of US are classified as obese and 9.4% have severe obesity. About 30% of patients with T2D have severe obesity. The combination of severe obesity and T2D significantly increases the risk of CVD, non-alcoholic fatty liver disease, and other comorbidities, which contribute to higher mortality rates. To tackle this heavy burden, there's a need for coordinated efforts that encompass prevention, early diagnosis, effective treatment, and patient education. The management of obesity faces several per…

Interventions
- DeviceAbbot Freestyle Libre CGM
Participants assigned to the CGM group will receive the Libre 2+ systems (Abbott Diabetes Care, Alameda, CA) upon randomization. This will include comprehensive training provided by a qualified healthcare professional. The training will cover detailed instructions on sensor placement, how to download and use the associated smartphone application, and guidance on interpreting the glucose data effectively. To ensure continuous and accurate monitoring, the CGM sensor will be routinely replaced every 14 days following randomization. Additionally, in the event of sensor detachment or loss, immediate replacement will be arranged to maintain uninterrupted glucose tracking. Regular sessions are conducted to analyze glucose trends, refine management strategies, and provide additional support or education on device usage.
