Dexcom G6 Discontinuation in 2026 – What It Means and How to Transition Smoothly to Dexcom G7

As someone living with Type 1 diabetes, I write this to help others in our community understand what’s changing—and what it means for daily life.

What Dexcom Officially Says

Dexcom has confirmed that manufacturing of the G6 CGM System will end on July 1, 2026. After that date, stocks may still be available in pharmacies or distribution for a limited period, but long-term availability is not guaranteed. Dexcom recommends working with a healthcare provider to transition to the G7 or the new G7 15-Day sensor before mid-2026 to ensure ongoing CGM access and support.

Why is the G6 Being Discontinued?

Dexcom states that as the company focuses on delivering next-generation CGM technology, older systems like the G6 need to be phased out so resources can be dedicated to newer products, including the Dexcom G7 and G7 15-Day.

In practical terms: the G7 line is the current direction for Dexcom’s product roadmap, meaning the G6 will eventually stop being supported and sold once production ceases.

A Closer Look at Dexcom G7 and the 15-Day Sensor

Dexcom’s newer systems include the G7—a fully redesigned CGM—and a longer-wear version called the G7 15-Day, which received FDA clearance and is expected to be available in 2025. The 15-day sensor offers significantly longer wear time compared to the standard G7 and is described as an industry-leading option for those 18 and older.

Dexcom G6 vs. Dexcom G7: Comparison Table

Feature	Dexcom G6*	Dexcom G7 (10-Day / 15-Day)
Manufacturing end	July 1, 2026	Current production (future updates expected)
Wear Time	~10 days	~10 days (standard) / ~15.5 days (15-day)
Warm-Up Time	~2 hours	~30 minutes (faster setup) / 60 minutes
Sensor + Transmitter	Separate	Integrated
Size	Larger	Smaller / more discreet
App Compatibility	G6 app only	G7 app & receiver ecosystem
Accuracy (MARD)†	~9.0%	~8.0–8.2% (slightly improved)‡

* Official manufacturer data and community sources provide these general performance characteristics; specific individual experiences vary.

†MARD (mean absolute relative difference) is one measure of CGM accuracy.

‡Dexcom has reported both G7 and G7 15-day accuracy measurements consistent with improved performance over prior systems.

What Users and the Community Are Saying

Across diabetes forums, including Reddit and community posts, reactions to the G6 discontinuation and G7 transition vary widely.

Users With Loyalty to G6

Some community members express that they trust the consistency and predictability of the G6, saying things like “G6 has worked well for me” and “I’m hesitant to switch because I know how my G6 performs.” Others have pointed to connection or data differences they’ve observed when trying the G7, including variability between CGM readings and finger-stick glucose checks. (These are self-reported sentiments from community forums, not clinical data.)

Concerns and Critiques

Common themes from user conversations include:

• Frustration with changes in sensor behavior or dashboard data interpretation
• Challenges when switching apps or accounts
• Concerns about the sensor restart behavior, which differs from some user practices with G6
• Discussions about availability timelines and potential stock shortages

These reflect subjective experiences from individual users and don’t represent clinical evidence.

How to Think About the Transition

If you’re currently using G6 and planning ahead for mid-2026 and beyond, here are some practical points to consider:

1. Talk With Your Healthcare Provider

Discuss your prescription and CGM plan so that you can transition to G7 or G7 15-Day in a way that aligns with your therapy and insurance coverage. Some users may be eligible for automatic pharmacy upgrades depending on their supplier.

2. Know the Ecosystem Changes

The G6 and G7 require separate apps and receivers. Sensors are not cross-compatible—switching means adopting a new setup and download process.

3. Understand Wear Time Options

The standard G7 typically lasts about 10 days, similar to the G6, but with a shorter warm-up period and a new 15-day option offering longer wear with fewer sensor changes.

Final Thoughts

The Dexcom G6 discontinuation marks a notable shift for many in the diabetes community. While some welcome newer technology and longer wear options, others remain cautious about performance and personal preferences.

As a community observer, I encourage people to stay informed, talk to their healthcare team, and share experiences—because each user’s needs and priorities can be different.
