Why your fart smells awful and how to cure it!

You’ve probably experienced a “gut feeling” before—that sense of uneasiness in your stomach that tells you something is off, but your brain hasn’t quite worked out what it is yet. But can you really trust what your gut tells you? In this episode, Adam is joined by Harvard gastroenterologist Trisha Pasricha to decode what’s really going on between your mind and your stomach. Trisha breaks down the science behind brain-gut communication and offers tips for when and how to listen to your gut when making decisions or assessing a new environment. She also seeks Adam’s advice on helping doctors empathize with patients’ pain and invites him to rethink his position on poop. Building on her book You’ve Been Pooping All Wrong, she explains what your bowel movements can tell you about your overall health, how to experience “poophoria,” and why you shouldn’t bring your smartphone to the bathroom.
