The Dexcom G6 CGM System's transmitters are water resistant. The G6 Sensor Pod is water resistant when the transmitter is installed properly. The receiver is not water resistant or waterproof, and can be damaged if moisture gets inside it. Water can also severely limit communication range with the G6, so you never want to prevent communication between the transmitter and display devices. This could cause the receiver to become damaged and a patient to miss a severe low or high blood glucose event or make a treatment decision that can result in injury. There is more information available in the Dexcom G6 CGM System User Guide.
