Evaluating Continuous Glucose Monitoring as an Intervention for Improving Glycemic Control in Middle-Aged Adults with Type 2 Diabetes

Type 2 diabetes (T2D) presents significant challenges for glycemic control, especially among middle-aged adults who face declining insulin sensitivity and multiple comorbidities. Traditional glucose monitoring methods, such as self-monitoring of blood glucose (SMBG) and hemoglobin A1c (HbA1c) measurements, often fail to capture glucose variability and episodes of hypoglycemia or hyperglycemia. Continuous glucose monitoring (CGM) offers a comprehensive alternative, providing real-time data and enabling proactive management of blood sugar levels. This review examined the clinical efficacy of CGM in improving glycemic control for middle-aged adults with T2D. It highlighted CGM’s ability to reduce HbA1c, increase time in range (TIR), and detect nocturnal hypoglycemia, while also discussing its impact on patient behavior, psychological well-being, and adherence to treatment regimens. The methodology for this review involved an in-depth analysis of peer-reviewed studies and clinical trials, focusing on the use of CGM in middle-aged adults with T2D. Barriers to CGM adoption, such as cost and perceived complexity, are also discussed, alongside the potential for future advancements in CGM technology to expand its role in personalized diabetes care. This article underscored the importance of CGM in achieving better long-term glycemic outcomes and improving quality of life for this population.
