Continuous glucose monitors (CGMs) measure the body’s glucose levels in real-time by sensing the glucose present in tissue fluid. CGMs are particularly useful after meals and overnight, as they can alert you if your glucose levels are getting too low or too high. 

Currently, four companies have personal CGM devices available in the US: Abbott (FreeStyle Libre and Freestyle Libre 2), Dexcom (the G6), Medtronic (Guardian Sensor 3), and Senseonics (Eversense). Compare each CGM device
