Dexcom Share: How to Share CGM Data with Family

What Is Dexcom Share?

Managing diabetes is rarely a solo journey. Whether you are a parent watching over a child with Type 1 diabetes or an adult whose family members want peace of mind, Dexcom Share is a game-changing feature built into the Dexcom CGM ecosystem. It allows you to share your real-time continuous glucose monitoring (CGM) data with up to ten followers, giving loved ones the ability to track your glucose levels from their own smartphones — no matter where they are.

How Dexcom Share Works

Dexcom Share works through the Dexcom G6 or G7 app installed on your smartphone. Your CGM transmitter sends glucose readings to your phone, and the Dexcom app then uploads that data to the cloud. Followers download the free Dexcom Follow app and can see your glucose readings, trends, and alerts in near real time — typically with a delay of just five minutes or less.

Both the sharer and the follower need a stable internet connection for the system to work properly. If your phone loses connectivity, followers will receive a notification so they know data may be delayed.

Setting Up Dexcom Share: Step-by-Step

1. Open the Dexcom G6 or G7 app on your compatible iOS or Android device.
2. Navigate to the Share section within the app menu.
3. Tap Invite Follower and enter your follower's email address.
4. Your follower will receive an email invitation to download the Dexcom Follow app.
5. Once they accept and log in, they will begin receiving your glucose data automatically.
6. You can customize alert settings so followers are notified when your glucose goes too high or too low.

The entire setup process takes less than ten minutes, making it one of the most accessible remote monitoring tools available for people with diabetes.

Customizing Alerts for Followers

One of the most valuable aspects of Dexcom Share is the ability to set custom glucose alert thresholds for followers. Caregivers can receive an urgent alarm if readings drop below 55 mg/dL — a critical safety net, especially overnight for parents of young children with diabetes. You can also set high glucose alerts so family members know when intervention or reminders might be helpful.

Followers can adjust the volume and timing of their own alerts independently, meaning a spouse sleeping in the same room can set louder overnight alarms without disrupting a coworker who is also following.

Who Benefits Most from Dexcom Share?

• Parents of children with Type 1 diabetes — Monitor your child at school or overnight without waking them.
• Adults living alone — Give family members confidence that help can come quickly in an emergency.
• Elderly individuals with diabetes — Allow adult children to stay informed without being intrusive.
• Athletes and active users — Keep a coach or training partner aware during intense workouts.

Tips for Getting the Most Out of Dexcom Share

To keep the system running smoothly, make sure your phone's Bluetooth is always enabled and the Dexcom app is allowed to run in the background. Regularly check that your transmitter is connected and your app is updated to the latest version. If you need help choosing the right Dexcom accessories or replacement components to keep your CGM performing optimally, mdsdiabetes.com offers a wide selection of CGM supplies and expert guidance tailored to your needs.

Privacy and Control

You remain in full control of your data at all times. You can remove a follower at any moment directly from the app, and followers can only view your data — they cannot make changes to your settings or alerts. This balance of transparency and privacy makes Dexcom Share a trusted tool for families navigating diabetes together.

Final Thoughts

Dexcom Share bridges the gap between independence and safety for people living with diabetes. By keeping loved ones informed in real time, it reduces anxiety, improves response times during glucose emergencies, and strengthens the support network that makes diabetes management more manageable for everyone involved.
