Dexcom said Dec. 4 that its continuous glucose monitors are now fully functional again after a service outage caused them to stop sending alerts over the weekend, according to The Wall Street Journal.
The Dexcom monitors are used by Type 1 diabetes patients to track their blood sugar levels. The monitors send patients alerts to their smartphones if their levels are too high or low.

The FDA has not received any adverse event reports related to the incident, according to the Journal.
