TMHS 632: The Surprising Science Of “Gut Feelings” & The Truth About Colonoscopies - With Dr. Emeran Mayer

The English language provides many examples of the communication system between the brain and the gut: a pit in your stomach, butterflies in your stomach, and gut feelings are all expressions we accept as standard. But beyond expressions, there’s a very real connection between our feelings and our biology. Because our brain and our enteric nervous system have a complex communication network, an imbalance in gut bacteria can lead to emotional stress and vice versa.

Dr. Emeran Mayer is a world-renowned gastroenterologist and neuroscientist with over 40 years of experience studying the complex and bidirectional relationship of the brain and the gut. He has published over 400 peer-reviewed scientific articles, written two bestselling books, and is a leading expert on all things gut and microbiome. On today’s show, he’s sharing the fascinating science on the relationship between our gut and our feelings.

This interview contains conversations on how the brain and gut communicate, including how the gut responds to stress.
