Continuous Glucose Monitoring (CGM) is a medical technology that provides real-time measurement of blood glucose levels for individuals with diabetes. The system consists of a small sensor inserted subcutaneously, commonly in the abdomen or upper arm, which measures glucose concentrations in interstitial fluid. The sensor transmits data wirelessly to a compatible receiver device or smartphone application, displaying current glucose readings and trends.
CGM systems offer continuous glucose data collection, contrasting with traditional point-in-time fingerstick blood glucose measurements. This technology enables users to monitor glucose fluctuations across 24-hour periods, including overnight readings that are typically missed with conventional testing methods. The continuous data stream allows for identification of glucose patterns, including post-meal spikes, dawn phenomenon, and exercise-related changes.
The real-time glucose information provided by CGM systems can inform diabetes management decisions regarding insulin dosing, meal planning, and physical activity timing. Users can observe their individual glycemic responses to specific foods, exercise routines, stress levels, and medications. This data facilitates personalized diabetes management approaches and may contribute to improved glycemic control when used as part of a comprehensive treatment plan.
