What is continuous glucose monitoring (CGM)?

How does a continuous glucose monitor work?

A CGM measures glucose levels in the fluid between your cells using a small sensor that’s painlessly4,5 applied to the back of your upper arm.
By measuring these levels continuously, CGMs show how your body responds to food, movement, and daily life, giving you a bigger picture17 of your trends over time.

CGM systems typically consist of two parts.

An app that shows your glucose data

The CGM app receives data, sent via Bluetooth from the sensor2, showing you real-time readings sent directly to your smartphone13.

How is CGM different from blood glucose monitoring (BGM)?

BGM and CGM both measure glucose levels, but in different ways. The key difference is that BGM gives you a snapshot of glucose at a single point in time617, while CGM painlessly tracks patterns throughout the day and night.
