Customizable alerts that work
for your patients

The Dexcom G7 app gives your patients the flexibility to customize
alert sounds and settings to best fit their lifestyle and needs.


Silence All

With this setting, all alerts will not sound or vibrate for up to 6 hours. Visual notifications will still appear on the lock screen.


Delay 1st Alert

It enables users to delay their first High alert until their sensor reading is high for a while, allowing them to make their glucose alerts work for them.


Quiet Mode

When this setting is enabled all Dexcom G7 alerts will vibrate. A users Urgent Low Glucose and Technical Alerts will still escalate to sound if not acknowledged.


Urgent Low Alert

Alerts a user when their sensor reading is at 3.1 mmol/L or below. This alert cannot be turned off or silenced.


Low Glucose Alert

Alerts the user when sensor readings is at or below the level set. A user customizes this setting to enable tighter control and help get ahead of lows.


Urgent Low Soon

Provides a 20-minute advance warning of when a user reaches 3.1 mmol/L so that they can act quickly and avoid a potential hypoglycemic event.


High Glucose Alert

Alerts you when sensor readings are at or above the set levels. It’s the yellow line on the trend graph.


Rising & Falling Fast Alerts

Let a user know when their sensor readings are changing quickly. They will see double arrows on your glucose reading. These alerts can be turned off in the Profile tab.
