Why choose Dexcom G6 for your patients
Revolutionizing diabetes management
Dexcom is dedicated to helping patients, and their healthcare teams, better manage their diabetes by developing innovative glucose sensing technology, software and products.
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, no routine fingerstick CGM system.*
Accuracy during critical times1
Supports improved glycemic outcomes
No routine 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.

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.
Despite their best intentions and efforts, many diabetes patients struggle to maintain optimal glycemic control.
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.
** Provides a warning up to 20 minutes in advance of severe hypoglycemia (glucose levels at or below 3.1 mmol/L)
† Lets users know when their sensor glucose is at or below 3.1 mmol/L. You cannot change or turn off the Urgent Low Alarm.
‡ When integrated with the Tandem t:slim X2 Insulin Pump.
§ Requires the Follow App and an internet connection. Followers should always confirm readings on the Dexcom G6 App or Receiver before making treatment decisions
