Welcome to Episode 015 of the PHW Podcast. In this episode, Dr. Jeff Davis sits down with Dr. Kristen Marvin to explore the fascinating and often overlooked world of gut health. What is our gut really doing for us every day? And why does it matter so much for the rest of our health? Together, they follow the digestive process from the first bite to the finish, breaking down the role of stomach acid, the small bowel's remarkable absorption power, and the trillions of bacteria that call our gut home. Dr. Marvin and Dr. Davis walk through the gut-brain connection, explain the truth about leaky gut and its link to autoimmune conditions, and discuss how the microbiome even influences hormone balance. You'll hear real clinical stories, practical takeaways, and evidence-based guidance on how to support your gut through food, hydration, movement, sleep, and stress. If you've ever wondered what your gut is really up to, this episode is a must-listen!
