If you or a loved one relies on smartphone-connected diabetes devices, it’s time to double-check your alert settings. The Health Sciences Authority (HSA) has issued a safety advisory regarding potential missed alerts on continuous glucose monitors (CGMs), insulin pumps, and automated insulin dosing systems when paired with mobile applications.
While there have been no reported cases in Singapore, international incidents highlight that missing critical alerts can lead to severe hypoglycemia (low blood sugar), hyperglycemia (high blood sugar), diabetic ketoacidosis, or even fatal outcomes.
Why Are Alerts Failing?
Alerts from smartphone-connected diabetes devices may not function properly due to various reasons, including smartphone settings, hardware changes, and software conflicts:
Smartphone Settings:
- Notifications disabled for the diabetes management app
- “Do Not Disturb” or “Focus Mode” blocking alerts
- App placed in “deep sleep” after extended inactivity
Hardware Changes:
- Connection to wireless earphones or car audio systems affecting alert volume or delivery
Software Conflicts:
- Mobile operating system (OS) updates that are incompatible with the medical application
How to Ensure Your Alerts Work Properly
- Follow manufacturer instructions for configuring your app’s settings
- Test alerts regularly to confirm they are functioning as expected
- Reach out to the device’s technical support if notifications fail to appear
This issue isn’t limited to diabetes management devices—other mobile health applications may also experience similar notification failures.
