A Continuous Glucose Monitor (CGM) is a state-of-the-art medical device designed to provide real-time glucose level readings for individuals managing diabetes. Unlike traditional fingerstick blood glucose meters, which offer single-point-in-time measurements, a CGM continuously tracks glucose levels throughout the day and night. This advanced monitoring system consists of a small sensor inserted under the skin, typically on the abdomen or arm, which measures interstitial glucose levels. The sensor wirelessly transmits data to a receiver or a compatible smartphone app, allowing users to monitor their glucose trends and patterns effortlessly.
