Clinical Outcomes of Patients With Type 2 Diabetes Using Continuous Glucose Monitoring: A Retrospective Study

Abstract

Background: Type 2 diabetes (T2D) is a chronic condition characterized by insulin resistance and dysregulated blood glucose levels. Continuous glucose monitoring (CGM) offers real-time glucose data, which may improve glycemic control and clinical outcomes in patients with T2D. This study evaluates the impact of CGM on clinical outcomes in patients with T2D.
Methods: A retrospective cohort study was conducted with 200 patients diagnosed with T2D who used CGM devices for at least 6 months. Data were collected from electronic health records, including HbA1c levels, blood glucose variability, incidence of hypoglycemic events, and diabetes-related complications before and after CGM use. Statistical analysis was performed to evaluate changes in clinical outcomes following the use of CGM.
Results: The use of CGM resulted in a significant reduction in HbA1c levels (from 8.2% to 7.3%, p < 0.01). Blood glucose variability decreased by 25%, and the incidence of hypoglycemic episodes dropped by 40%. Additionally, patients using CGM had a lower incidence of diabetes-related complications, such as diabetic retinopathy and nephropathy, compared to those not using CGM.
Conclusion: CGM significantly improves glycemic control, reduces blood glucose variability, and lowers the risk of hypoglycemic events in patients with T2D. These findings suggest that CGM can be an effective tool for managing T2D and preventing long-term complications.
