Introduction: Blood glucose monitoring has evolved over the 20th century into a vital component of managing diabetes mellitus. From a doctor’s office to the patient’s home, self-monitoring blood glucose (SMBG) became the gold standard upon which healthcare providers manage all forms of diabetes mellitus today. In recent years, continuous glucose monitoring (CGM) has shown superior results compared to SMBG in the management of type 1 diabetes. This clinical article will explore the application of CGM technology for type 2 diabetes.
Methods: A PubMed literature search was performed across multiple databases, including PubMed, Google Scholar, and Diabetes Care Online.
Results: A literary search yielded various meta-analysis, randomized controlled studies, and prospective cohort studies that compared the use of CGM to SMBG in diabetes management. Fifteen (15) studies were selected for the review of CGM application to type 2 diabetes.
Conclusion: Blood glucose monitoring and the management of diabetes mellitus is changing with the application of CGM technology. Research shows strong evidence for CGM benefiting care in type 1 diabetes and emerging data shows similar results for type 2 diabetes. Improvements in glycemic control, reduced hypoglycemia, and better quality of life have been demonstrated using the CGM for both types of diabetes. The CGM technology also provides insights to the effects of glycemic variability in various diabetes complications and medical conditions. Cost and insurance coverage of CGM is one of the most significant barriers to more widespread use. Additional research is needed to confirm the full implications of the CGM in diabetes management and applications for future research of non-diabetes related conditions.
