What is Dexcom CGM?

Dexcom CGM Systems automatically send your glucose numbers to your smartphone or Dexcom receiver, day and night. Unlike fingersticks that give you a number for a single point in time, Dexcom CGM lets you see your glucose numbers continuously, so you’ll always know when you’re trending high, low, or when you’re good to go.

No fingersticks*, no scanning!

A small wearable sends glucose readings in real time to a smartphone or Dexcom receiver every five minutes.*Fingersticks required for diabetes treatment decisions if symptoms or expectations do not match readings.
