What is continuous glucose monitoring (CGM)?

A continuous glucose monitoring (CGM) system tracks glucose levels throughout the day and night and can alert you if your levels go too low or when you’re high. It measures your glucose level at regular intervals, as frequently as every 5 minutes, and translates the readings into easy-to-read data and insights. It can also show the direction your glucose is heading and how fast.

How does a continuous glucose monitoring system work?

Instead of looking at one glucose number at a single moment in time, a CGM system tracks your glucose levels day and night. Here's how:
