A Review on Continuous Glucose Monitoring in Diabetes management

In the last two decades, the global prevalence diabetes has increased significantly, leading to various chronic complications and heightened morbidity and mortality. Regular assess ment of glycemic control is crucial in diabetes management. Common techniques include self-monitoring of blood glucose and measurement of hemoglobin A1c. While SMBG helps evaluate therapy response, it has limitations such as providing singular measurements and dependency on patient adherence. HbA1c, reflecting average glucose levels, is a gold standard, but it doesn't capture glycemic fluctuations and can be unreliable in certain health conditions. Continuous glucose monitoring has become a valuable tool, offering insights into glycemic trends, time spent within the target range, and hypoglycemia. CGM data, despite a time lag with traditional blood glucose readings, provides comprehensive understanding over a 10–14-day period. CGMPs provide valuable insights into glycemic excursions and potentially hazardous fluctuations that might be overlooked with traditional SMBG.
