39. Why Does Your SIBO Keep Coming Back? (And What Most Treatments Miss)

Is SIBO (Small Intestinal Bacterial Overgrowth) really the root cause of your bloating and food intolerances — or is it a downstream effect of deeper dysfunction?In this episode of The Histamine Well Podcast, Joanne explains why SIBO rarely develops in isolation and why antibiotics or herbal antimicrobials alone often fail to prevent relapse.If you’ve been stuck in the cycle of treating SIBO repeatedly without lasting improvement, this episode explores the underlying mechanisms that may be driving bacterial overgrowth in the first place.Joanne unpacks how impaired gut motility, nervous system dysregulation, low stomach acid, sluggish bile flow, estrogen dominance, mold toxicity, thyroid dysfunction, and histamine intolerance all contribute to creating the perfect environment for SIBO to thrive.Rather than focusing solely on eliminating bacteria, this episode highlights a terrain-based, root-cause approach to restoring long-term digestive health.In This Episode, We Discuss:What SIBO (Small Intestinal Bacterial Overgrowth) actually isWhy SIBO often returns after antibioticsThe migrating motor complex (MMC) and gut motilityThe vagus nerve and nervous system regulationBile flow and its antimicrobial roleEstrogen dominance and SIBOMold toxicity and mitochondrial dysfunctionThe connection between SIBO and histamine intoleranceWhy relapse happens — and how to prevent itIf you found this episode helpful, please subscribe, leave a review, and share it with someone navigating SIBO or chronic gut issues.For worldwide online consultations via Zoom, visit: www.joannekennedynaturopathy.com✨ Want more?
