33. IBS and the Gut-Brain Connection: 3 Nervous System Tools for Relief with Dr. Megan Riehl - IBS Nutrition Podcast by The IBS Dietitian | Lyssna här

Do you get sweaty, dizzy, clammy feeling on the toilet?

If your scopes came back "normal" but your symptoms are very real, this episode is for you. GI psychologist Dr. Megan Riehl joins Jessie to unpack why IBS is now classified as a Disorder of Gut-Brain Interaction (DGBI), what the vasovagal response has to do with your flare-ups, and how your autonomic nervous system may be driving cramping, urgency, and that clammy "oh no" bathroom feeling.

You'll learn:

What DGBI actually means and why the name change matters
The science behind the gut-brain axis and vasovagal reactions
When to consider working with a GI psychologist
3 evidence-based tools you can use today: diaphragmatic breathing, body scanning, and gentle movement

Dr. Riehl is Director of the GI Behavioral Health Program at the University of Michigan and co-author of Mind Your Gut. Tune in for validating science and practical relief you can start using today.
