Glucose emergencies happen fast—sometimes too fast for the person experiencing the low to react. The ADA confirms that CGMs reduce severe hypoglycemia events and allow family or caregivers to intervene sooner.

What’s happening

CGM sharing sends real-time alerts to the phones of caregivers, parents, or trusted loved ones. When levels drop dangerously, someone else is notified—even if the patient is asleep, driving, or cognitively impaired during a low. During a 2024 educational video on diabetes tools, Sally explained how sharing features add a protective layer for families:

“Parents can get notifications if their child is going critically low or high.”
— Sally Figueroa 

This reassurance changes daily life for households managing Type 1 or Type 2 Diabetes.

What you can do

• Enable sharing in the CGM app settings.
• Choose at least one adult who can respond to alerts.
• Review alert thresholds with your endocrinologist.
• Keep glucagon accessible in multiple locations.

What to avoid

• Assuming alarms will wake you every time.
• Relying on vibration-only modes during sleep.

How to move forward

Shared monitoring isn’t surveillance—it’s safety infrastructure for families navigating unpredictable glucose swings.
