The Impact of Initiating Continuous Glucose Monitoring (CGM) in Adults Diagnosed with Pre-Type 2 Diabetes

Pre-diabetes is a condition diagnosed when individuals have higher than normal blood glucose levels that are not yet in the diabetic range. The condition can occur at all different life stages but is most common in older ages and obese individuals. A commonly agreed-upon method of diagnosis is measuring glycosylated hemoglobin (HbA1c), with levels between 5.7% and 6.4% indicating pre-diabetes. The condition is considered intermediate at this stage but has a variety of comorbidities, most notably its high risk of progressing into type 2 diabetes. Methods such as monitoring, education and healthy lifestyle choices can significantly affect the outcome of pre-diabetes, potentially reducing HbA1c levels or slowing disease progression. Unfortunately, many individuals lack the proper tools and education to address and manage their disease adequately. Continuous glucose monitors (CGM) are commonly used in blood glucose monitoring for diabetes management, typically for type 1 diabetics. These devices report real-time data while identifying trends and changes, allowing users to better understand and monitor their condition. Closely monitoring blood glucose levels could aim to improve glycemic stability in pre-diabetics. However, there is a gap in existing research on the impact of CGM use in monitoring adults with pre-diabetes.
