Continuous Glucose Monitoring (CGM) is an advanced method for managing diabetes that provides real-time glucose readings throughout the day and night. Unlike traditional finger-prick tests, the CGM device uses a tiny sensor inserted under the skin to measure glucose levels in the interstitial fluid. The sensor sends this data to a display device, allowing users to see their glucose levels in real-time, track trends, and receive alerts for hypo and hyperglycemia.
Dexcom offers a variety of CGM devices with a wear period of 10 days. These devices provide continuous glucose readings every five minutes and feature customizable high and low alerts to notify users of at-risk blood glucose levels.
