Smart devices not included

Redefining CGM and a new standard in diabetes management.

From "snapshot" glucose readings to continuous glucose monitoring (CGM) systems that provide around-the-clock data visibility, 
Dexcom is defining a new chapter in diabetes therapy management with a revolutionary, zero fingerstick CGM system.*


Accuracy during critical times1


Supports improved glycemic outcomes
(multiple measures)2-5


Zero fingersticks* or scanning required

* If your glucose alerts and readings from the G6 do not match symptoms or expectations, use a blood glucose meter to make diabetes treatment decisions.


Customizable high and low alerts


Real-time glucose data sharing

Do not make diabetes treatment decisions based upon Dexcom Share and Dexcom Follow app readings. Always confirm with your compatible smart device or Dexcom receiver.

What is CGM?

CGM gives users a more complete picture of their glucose levels and trends. Unlike a blood glucose meter which provides just a single reading with each fingerstick, CGM shows patients where their glucose is going and how fast.

Patient Benefits

Despite their best intentions and efforts, many diabetes patients struggle to maintain optimal glycemic control.

Proven Outcomes

A growing amount of evidence substantiates the efficacy of Dexcom Continuous Glucose Monitoring (CGM) Systems for insulin-using patients with Type 1 or Type 2 diabetes.
