## Resource

Continuous glucose monitoring didn’t start as sleek apps and tiny sensors — it began with chunky receivers, short wear times, and a lot of skepticism. In this episode, Dr. Jeremy Pettus and Dr. Steve Edelman sit down with Dexcom CEO and original sensor engineer Jake Leach to trace the evolution of CGM from those early “Tylenol-shaped” receivers and repurposed pagers to today’s G7 system and beyond. They walk through the major turning points: abandoning long-term implants for subcutaneous sensors, proving that real-time CGM meaningfully improves time in range and safety, and pushing back against old-school thinking that insisted patients shouldn’t see their own data. From STS 3-Day to Seven Plus, G4, G5, G6, and now G7, Dr. Edelman, Dr. Pettus, and Jake Leach break down what each generation added — better accuracy, easier insertion, smartphone and cloud connectivity, and integration with pumps and AID systems. Most importantly, Dr. Edelman, Dr. Pettus, and Dexcom CEO Jake Leach, focus on what’s coming next and what it means for people living with diabetes today: the 15 day Dexcom G7 sensor, Smart Basal insulin titration for people with type 2 diabetes, AI-powered food logging, and the upcoming G8 platform designed to measure multiple analytes (glucose plus ketones and more) — all while pushing toward broader access and affordability. Key Topics: Early Dexcom Days & STS 3-Day: How Dexcom pivoted from implantable sensors to disposable subcutaneous CGMs and what the earliest systems were really like. Blinded vs Real-Time CGM: The ethics debate, safety implications, and studies proving real-time data improves time in range and reduces hypoglycemia. Seven Plus, G4 & G5: Major accuracy improvements, longer wear times, and the move to smartphone-based monitoring. G6 &a…
