Dr. Will Bulsiewicz, The Gut Health MD

I'm Dr. Will Bulsiewicz — most people call me Dr. B. I'm a triple board-certified gastroenterologist, internationally recognized gut health speaker, 3X New York Times bestselling author of Fiber Fueled and Plant Powered Plus, and founder of 38TERA.

With over two decades of clinical experience and deep expertise in microbiome research and nutrition science, I translate cutting-edge gut health science into practical strategies that actually work in real life.

On this channel you'll find science-backed videos on gut health, the gut microbiome, leaky gut, IBS, bloating, constipation, fiber, chronic inflammation, colon cancer prevention, the gut-brain connection, plant-forward nutrition, and longevity — plus full episodes of The Gut Insiders podcast with Chuck Carroll.

My mission is simple: help you understand what's happening inside your gut, reduce chronic inflammation, and build lasting health from the inside out.
