Most people with T1D have switched their CGM high alert off. Not because they do not care - because it goes off every time they eat and there is nothing they can do about it. Episode 37 is about what Dexcom built to fix that.

Adam Dawes, Senior Medical Affairs Manager at Dexcom UK and Ireland - and a former paediatric diabetes nurse specialist - joins John Pemberton for the third manufacturer episode of the CGM Series. An honest clinical conversation about the Dexcom G7 and ONE+, what separates them, and where Dexcom is heading next.

This episode covers:
- Dexcom G7 vs Dexcom ONE+: same hardware platform, different software, and what that means for matching the right sensor to the right patient
- Delay 1st Alert: why it is one of the most underused alerts in CGM, how it eliminates alarm fatigue without reducing safety, and how John uses it himself
- AID integrations: Tandem T:slim X2, Omnipod 5, mylife, and the Tandem Mobi
- CGM for type 2 diabetes: the biofeedback argument and why immediate glucose feedback changes behaviour in ways a quarterly HbA1c never can
- The Dexcom roadmap from ATTD 2026: 15-day sensor, Dexcom G8 next generation sensor, EPIC integration, Clarity updates, and generative AI
- Why insulin dosing will never be a commodity market - and what people with T1D need to understand as new CGMs enter the UK
- The FDA manufacturing findings: what happened, how Dexcom responded, and why the new Ireland factory matters
