What is Continuous Glucose Monitoring? (CGM)



How CGM works?

1. Sensor Application

The Continuous Glucose Monitoring (CGM) sensor is a self-applied device that sits partially beneath the skin1

2. Data Insights

It measures interstitial glucose levels at regular intervals, which a reader can then scan for more detailed data insights!

3. Scanning the readings

With every painless1 scan, the reader displays the current glucose reading and a glucose trend arrow that shows if glucose levels are going up, going down or staying steady.

The benefits of Continuous Glucose Monitoring (CGM):

Glucose readings without painful fingerpricks1

Continuous Glucose Monitoring (CGM) can take accurate readings from the interstitial fluid surrounding your tissue cells below your skin.

Trends and patterns to help better manage glucose levels

Continuous Glucose Monitoring (CGM) is an easy-to-use device that provides you with real-time glucose tracking. It also allows for monitoring of past glucose levels and insights on trends and patterns2


Why should I use CGM?

Get a full picture

  CGM shows you where your glucose levels were, where they are and where they’re headed. It also helps you see the impact of food and physical activity on your glucose levels so you can see trends and patterns.

No fingerpricks1

CGM uses a small sensor paired with your reader, which saves you from the pain of fingerpricks1

Feel in control

CGM is clinically proven to significantly reduce hypoglycemia4,5,6 while also lowering HbA1c levels4,5,6

Here’s why FreeStyle Libre is right for you:

  • Approved for usage in a broad range of patient population

  • Make treatment changes over time basis your glucose trends

  • Track changes over time to help hyperglycemia and hypoglycemia episodes1

  • Get a complete picture of glucose levels to make informed treatment decisions1



1. Scanning the sensor to obtain glucose values does not require fingerpricks.

2. To get a 24-hour glycemic picture, users need to scan at least once every 8 hours.
