Episode 17: Mastering Motility: SIBO & the MMC With Dr Allison Siebecker

Today’s guest is Dr. Allison Siebecker, the renowned 'Queen of SIBO'. She is a naturopathic physician, award-winning author, clinician and educator, and this week she joins me to unpack one of the most important (but often overlooked) pieces of the gut health puzzle: motility. We explore the migrating motor complex (MMC), why it matters, and how poor motility can contribute to chronic conditions like SIBO. Dr. Siebecker shares her personal journey to working in the SIBO space, explains how to spot motility issues, and so much more. If you're struggling with gut symptoms, this episode is a must-listen for expert insight into how your gut motility might just be the missing piece.

In this episode, we chat about:

  • Dr. Siebecker’s own journey with gut health
  • What motility is and how it’s linked to small intestinal bacterial overgrowth
