Diabetes Dialogue: Updates from Dexcom at ADA 2025, with Kevin Sayer

Welcome back to Diabetes Dialogue!

In this special episode recorded at 85th Scientific Sessions of the American Diabetes Association (ADA 2025), hosts Diana Isaacs, PharmD, an endocrine clinical pharmacist, director of Education and Training in Diabetes Technology, and co-director of Endocrine Disorders in Pregnancy at the Cleveland Clinic, and Natalie Bellini, DNP, program director of Diabetes Technology at University Hospitals Diabetes and Metabolic Care Center, welcome Kevin Sayer, chief executive officer of Dexcom, for a candid conversation about the evolving landscape of continuous glucose monitoring (CGM). From Dexcom’s origins to the latest updates on G7 and the emerging Stelo app, the discussion traces the company's journey and innovation roadmap.

Sayer reflects on how sharing real-time glucose data transformed the diabetes management experience—making life safer not just for children but also for adults living independently, caregivers, and entire family networks. Dexcom’s emphasis on data transparency has laid the groundwork for a broader shift toward individualized care, especially for those with type 2 diabetes.

The episode dives into Dexcom’s growing footprint in type 2 diabetes management, with expanded coverage across the nation’s three largest pharmacy benefit managers. Sayer emphasizes that CGM is not just about preventing hypoglycemia in insulin users anymore—it’s a behavioral and educational tool. Patients can now “see” the impact of food choices, physical activity, and medication adherence in real time, prompting lifestyle changes that might otherwise take years of trial-and-error clinical encounters.

The hosts also explore the integration of AI-powered features like food recognition, enhancements in the Stelo app for wellness tracking, and the implications of new CGM algorithms as G7 expands to 15-day wear. Sayer addresses the unique needs of people with and without diabetes and the regulatory constraints in tailoring CGM algorithms to specific use cases.

In a lighter moment, Sayer shares his enthusiasm for Dexcom’s public-facing campaigns, including recent collaborations with Lance Bass and Nick Jonas as well as the company’s network of “Dexcom Warriors.”
