Continuous glucose monitoring: The future of diabetes management

Abstract

Continuous glucose monitoring (CGM) technology has the potential to revolutionize diabetes care in the near future because of the real-time feedback it provides about therapeutic interventions and variations in lifestyle or dietary intake. In short, CGM has made the attainment of near-normal blood glucose concentrations an achievable goal for most patients with diabetes. Several challenges remain to be addressed, however, including the high cost of the devices, limitations in approved clinical uses, and insurance coverage for the technology. This article reviews the CGM technology currently available in the United States, its approved uses, and its limitations.
