The Dexcom G7 measures interstitial glucose every 5 minutes and transmits readings automatically to the Dexcom G7 app or an optional handheld receiver. The all-in-one sensor integrates the transmitter into a single wearable unit, approximately 60% smaller than the G6, with a 30-minute warmup period. The system includes the Urgent Low Soon predictive alert, warning users up to 20 minutes before glucose is predicted to reach 3.1 mmol/L. Health Canada approved for Type 1, Type 2, and gestational diabetes in people aged 2 and older, including use during pregnancy. Integrates with the Tandem t:slim X2 with Control-IQ for automated insulin delivery.
