To explore what’s going on, I’m joined by two experts in the diabetes space: Kamil of the Nerdabetic YouTube channel, and Dr. David Ahn, a practicing endocrinologist. We discuss the recent FDA warning le...

Today we explore the evolution of continuous glucose monitors (CGMs) — from the first professional CGM in 1999 to the advanced tech driving today’s AID systems, and how these devices changed patient lives along the way. Dr. Grazia Aleppo, a leading endocrinologist and early CGM believer, joins to discuss early CGM innovations, the challenges of adoption, and pivotal research that expanded global access. Plus, we look ahead to what ...

I sit down with someone who wore the first consumer insulin pump—the AutoSyringe We dive into what diabetes treatment was like at the time, how the early pump worked, and how decades of evolving tech have shaped her journey and inspired her to educate others. It’s a powerful look at how far we’ve come in diabetes innovation.

I sit down with veteran game developer and T1D dad Sam Glassenberg, creator of Level One—a new smartphone game designed to teach newly diagnosed patients and their families the fundamentals of T1D management. From insulin-to-carb ratios to the impact of exercise and fat on blood sugar, Level One turns complex concepts into fun, interactive levels. With early praise from endocrinologists and patients alike, this could be the educati...

Today’s CGMs measure glucose through fluid under the skin—but what if we could measure it directly from the blood? Today we explore Glucotrack, an implantable device that could become the world’s first continuous blood glucose monitor (CBGM). I’m joined by Glucotrack's CEO and Chief Scientific Officer to discuss the major advantages this device could offer over today’s CGMs. We cover how the sensor works, how it's implanted, and it...

I share my experience after nearly three months using the Tandem Mobi, the smallest tubed hybrid closed-loop pump currently available in the U.S. I’m joined by diabetes educator and fellow Mobi user David Mina to dive deep into how Tandem’s Control-IQ algorithm works — including updates with Control-IQ+ — and what to consider before switching from other pumps like the Omnipod. We also discuss David’s journey to becoming an educator...

We take a journey back to the roots of the #WeAreNotWaiting movement—before CGM follower apps—when a group of determined parents and developers built their own tools to monitor glucose remotely. I sit down with James Wedding, founder of the Nightscout Foundation, to talk about the early days of Nightscout, how it transformed life for families managing diabetes, and the powerful role the open-source community played in pushing the i...

In this episode, we dive into the major shift happening in the U.S. diabetes tech industry: insulin pumps are moving from Durable Medical Equipment (DME) to pharmacy benefits, offering easier access, lower costs, and more flexibility for users. I’m joined by Jeff DelVerne, author of The Healthcare Economy Substack and Director of Payer Relations at Beta Bionics, to break down what this transition means for people with diabetes. We ...

In this episode, I sit down with Amy Tenderich, one of the first diabetes bloggers, whose open letter to Steve Jobs called for better, more user-friendly diabetes technology. That bold move launched her deeper into the world of diabetes advocacy and innovation, eventually leading her to create D-Data Exchange—a powerful forum where industry leaders, regulators, and patient voices come together to push diabetes tech forward. We talk...

Can we stop type 1 diabetes before it starts? I’m joined by Sam Reich, CEO of SAB Bio, and Dr. Mike Haller, a leading T1D researcher, to explore an innovative new therapy called SAB-142. Unlike traditional thymoglobulin, which is derived from rabbits, SAB’s therapy uses a fully human version produced by genetically engineered cows—potentially eliminating harmful side effects like serum sickness. We unpack how this treatment could d...
