the use of libre to improve metabolic control and reduce reliance on medication

Conditions: Diabetes Mellitus, Type 2

Summary: gem (glycemic excursion minimization) is a new lifestyle treatment for type 2 diabetes that aims to lower glucose levels after meals and snacks. this is different from the current lifestyle treatment, which is to lose weight. this study is trying to find out if people who are newly diagnosed with type 2 diabetes can use a continuous glucose monitor together with the gem lifestyle to improve control of their diabetes. study participants will follow the gem lifestyle for 4 months (1 month of treatment and 3 months of maintenance) instead of seeking usual care (medications or weight loss programs) to lower blood glucose.

for people who are newly diagnosed with type 2 diabetes (t2d), it might be possible to delay or prevent the need for diabetic medications by reducing postprandial glucose (ppg). our glycemic excursion minimization (gem) lifestyle intervention can reduce ppg, but it depends on blood glucose feedback to help the user learn what elevates their ppg. this study examines if continuous feedback from the libre 2 continuous glucose monitor (cgm) will be advantageous for reaching the goals of gem. we will recruit 18 adult participants newly diagnosed with type 2 diabetes who are interested in using the libre 2 cgm. six participants will be recruited from each of the primary care clinics at the university of virginia (dr. cox), the university of colorado (dr. oser) and the university of west virginia, east branch (dr. cucuzzella). each site will also search their medical records to select 4 participants who match their study participants, meet the study criteria, but are being treated with routine care. these data will form the routine care control group (n=12). routine care participants will follow their doctor's treatment recommendations, while gem participants will complete the 1-month, self-directed gem lifestyle training using the libre 2 cgm and a fitbit to monitor progress. they will then maintain the gem lifestyle for 3 more months. the total treatment effect (a measure of treatment effectiveness that considers both a1c and medication changes) will be calculated pre- and post-treatment from medical record data. cgm data from gem participants will be collected and analyzed. cgm sensor use will be tracked to estimate participant engagement. we anticipate this multi-center pilot project will demonstrate the benefits of using libre 2 with a structured lifestyle intervention designed to reduce postprandial blood glucose excursions for individuals newly diagnosed with t2d.
