About this episode
If you have been dealing with bloating, irregular digestion, sensitivities, or feeling off after meals, this episode will help you understand what your gut is trying to communicate. In today's episode, I sat down with Dr. Rajan Karan, a gastrointestinal surgeon and gut-health researcher who makes complex digestive science feel simple and grounded. We explore why digestion is more than isolated symptoms and how the microbiome functions as a living ecosystem that reflects your stress levels, routines, food diversity, and nervous system patterns. We also discuss the role of fiber, the oral microbiome, healthy transit time, and the small daily habits that genuinely improve gut resilience. This conversation is a reminder that supporting digestion does not require extremes. It begins with accessible, sustainable practices that help your whole body feel more rooted. Dr. Karan Rajan is a board-certified gastrointestinal surgeon and gut-health researcher known for translating complex physiology into practical guidance people can apply right away.
