“I can’t think of any medical condition where you can have this type of fry but not that type of fry.”

– Dr. Vish Avinashi

Pediatric gastroenterologist Dr. Vish Avinashi joins Dr. Mariam Hanna for an episode that jumps head first into the overlapping world of allergy and GI. From ARFID to EOE, they talk about the murky middle ground where food fears, immune triggers, and gut symptoms collide—and how allergists can better navigate it all with the help of a friendly gastroenterologist.

On this episode:

  • How to recognize ARFID and why history, not testing, is your best diagnostic tool

  • Common pitfalls in celiac diagnosis—and why a positive TTG doesn’t always mean celiac

  • New, and surprising, treatments for IBS, including nerve stimulation and gut-directed hypnotherapy

  • What the microbiome research does—and doesn’t—tell us

When it comes to navigating the overlap between allergy and GI, remember: always learning, always listening, always befriending a gastroenterologist.
