This powerful combination provides individuals with convenient access to their real-time glucose data right on their wrist. In this article, we will provide a detailed guide on how to connect your Dexcom to your iWatch and make the most of this innovative integration.

Compatibility and Requirements:


Before getting started, ensure that your Dexcom CGM system is compatible with the iWatch. Check the Dexcom website or consult with your healthcare provider to verify compatibility. You will also need to have the Dexcom app installed on your iPhone.

Pairing the Dexcom CGM System:

To connect your Dexcom CGM system to your iWatch, begin by pairing it with your iPhone. Follow the instructions provided by Dexcom to set up the CGM system and pair it with your iPhone. Ensure that the Dexcom app is properly installed and functioning on your iPhone before proceeding to the next step.

Enabling Dexcom App on the iWatch:

Once your CGM system is successfully paired with your iPhone, it's time to enable the Dexcom app on your iWatch. Open the Watch app on your iPhone and navigate to the "My Watch" tab. Scroll down until you find the Dexcom app and tap on it. Enable the toggle to show the app on your iWatch's home screen.

Glance and Complications:

The iWatch allows you to add the Dexcom app as a glance or complication for easy access to your glucose data. To add it as a glance, swipe up on the iWatch face and tap the Glances screen. Swipe left or right until you find the Dexcom glance, and tap "Add." To add it as a complication, press firmly on the iWatch face and enter the customization mode. Find an available spot and select the Dexcom app from the list of available complications.

Setting Up Notifications and Alerts:

To receive notifications and alerts for glucose readings on your iWatch, make sure they are properly configured in the Dexcom app settings on your iPhone. Open the Dexcom app and go to the settings section. Customize your alerts and notifications based on your preferences and desired glucose thresholds. Ensure that notifications are enabled for the Dexcom app in the Watch app on your iPhone as well.

Glucose Data on Your iWatch:

Once your Dexcom CGM system is connected to your iWatch, you can access your real-time glucose data directly on your wrist. Open the Dexcom app on your iWatch to view your current glucose reading, trend arrows, and graph. Swipe left or right to navigate between different views or time periods.

Customizing Dexcom Complications:

The Dexcom complication on the iWatch face can be customized to show different glucose data or trends. Press firmly on the iWatch face to enter customization mode. Tap on the Dexcom complication and choose the specific glucose data or trend you want to display. You can choose from options like current glucose, trend arrows, trend graph, or high/low glucose alerts.

Glucose Alerts and Responses:

When your Dexcom CGM system detects high or low glucose levels, your iWatch will display alerts and notifications based on your configured settings. You can respond to these alerts directly from your iWatch by acknowledging or dismissing them. For urgent situations, you can take appropriate action, such as checking your glucose levels, treating hypoglycemia, or contacting your healthcare provider.

Utilizing the Dexcom Widget:

The Dexcom app also offers a widget that you can add to your iWatch's home screen for quick access to glucose data. Swipe right on the iWatch face to access the widget screen and scroll down to find the Dexcom widget. Add it by tapping the "Edit" button, then tapping the "+" icon next to the Dexcom widget.

Data Synchronization and Accessibility:

Your Dexcom CGM system and iWatch work together to provide seamless data synchronization. Glucose readings captured by the CGM system are automatically synced to the Dexcom app on your iPhone, which in turn syncs with your iWatch. This ensures that you have continuous access to your glucose data across multiple devices.

Connecting your Dexcom CGM system to your iWatch opens up a new realm of convenience and accessibility for diabetes management.
