88: The Future of Longevity: How Science is Redefining Human Healthspan with Dr. Darshan Shah
Monday, 23 February, 2026
In this episode of the Thyroid Pharmacist Healing Conversations podcast, Dr. Izabella Wentz interviews Dr. Darshan Shah – physician, former surgeon, and Founder/CEO of Next Health – about the future of longevity and how science is redefining human health span. Dr. Shah shares how he reversed his own metabolic and autoimmune issues, why “health span” matters more than simply living longer, and how to prioritize lifestyle foundations before exploring advanced longevity interventions like peptides, regenerative therapies, and plasma exchange. What you’ll learn in this episode: Longevity is really about health span (not just life span). Dr. Shah explains why the next decade is likely to bring major improvements in how long we can stay vibrant – with stable blood sugar, good sleep, strength, and mental clarity – rather than simply “adding years.” The four lifestyle pillars that move the needle most. Instead of chasing every trend, Dr. Shah focuses on nutrition/metabolic health, movement/exercise, sleep/recovery, and stress/emotional regulation. When these are dialed in, everything else works better – including supplements, hormones, and advanced therapies. Why metabolic health is the foundation for almost everything. Blood sugar dysregulation isn’t just about diabetes – it impacts cardiovascular health, brain health, infection risk, inflammation, and even cancer risk. Dr. Shah shares how to measure metabolic health (fasting insulin, A1C, CGMs), and why your mirror can’t tell you the whole story. Sleep tracking can reveal issues years before they become diagnoses. Many people think they sleep “fine,” but their data shows minimal deep sleep and frequent wakeups. Dr. Shah shares simple high-impact strategies (like consistent bedtime, phone out of the bedroom, and sauna), and Dr. Wentz shares how she’s used tracking to discover what promotes deep sleep. Peptides, stem cells, and regenerative medicine are exciting, but timing matters. Dr. Shah discusses peptides like GLP-1s (which may support immune regulation beyond weight loss), immune-supportive peptides, and collagen-support tools, plus stem cells, exosomes, and what may be coming next in regenerative science. A true “longevity clinic” should help you get healthy first – not just sell biohacks. Dr. Shah breaks down Next Health’s four-part approach: lifestyle optimization, functional medicine root-cause work, prevention/early detection, and then longevity interventions. It’s about becoming the boss of your biology – guided by data. Tune in to learn more about boosting your health span, tracking key biomarkers, and choosing longevity tools wisely.
