IBS affects over 300 million people globally, yet remains one of the most misunderstood gut conditions. In this episode, we explore the latest science uncovering the real drivers behind IBS - and why your gut microbiome may hold the key to understanding it.
Joining us is Dr. Will Bulsiewicz, a board-certified gastroenterologist and ZOE’s U.S. Medical Director. Dr. Will breaks down why IBS is so difficult to diagnose, how stress and modern lifestyles are making symptoms more common, and what “problematic” poo can tell us.
We then dive into the science: how the gut-brain axis influences everything from pain to food intolerances, why women are disproportionately affected, and how a disrupted microbiome plays a central role in IBS.
Finally, Dr. Will shares practical strategies backed by the latest research - from dietary changes to cutting-edge treatments - offering hope for healing and prevention.
Whether you're living with IBS or simply want to understand your gut better, this episode is packed with insights into one of the most common yet elusive health conditions of our time.
