How Mould Mycotoxins Cause SIBO

Uncovering the Hidden Connection Between Mould Toxicity & SIBO

In this episode of The Histamine Well Podcast, Joanne dives deep into the overlooked connection between mould exposure, mycotoxins, and Small Intestinal Bacterial Overgrowth (SIBO). If you’ve been struggling with chronic bloating, reflux, constipation, diarrhea, food intolerances, histamine symptoms, or ongoing digestive dysfunction that never fully resolves, this episode explores why mould toxicity may be the missing piece.

Joanne explains how mould and mycotoxins can profoundly impact the nervous system, particularly the vagus nerve, which plays a critical role in regulating digestion, stomach acid production, bile flow, pancreatic enzymes, and gut motility. When these systems become impaired, the digestive tract becomes the perfect environment for bacterial overgrowth in the small intestine.

You’ll learn why so many people with mould illness also develop SIBO, histamine intolerance, mast cell activation, and multiple food sensitivities — and why conventional SIBO treatments often fail when the underlying mould issue is not addressed.

This episode covers:

  • The connection between mould exposure and SIBO
  • How mycotoxins affect the nervous system and vagal tone
  • Why low stomach acid contributes to bacterial overgrowth
  • The role of sluggish bile flow and poor gut motility in chronic digestive symptoms
  • How mould can trigger histamine intolerance and inflammation
  • Why chronic SIBO cases may not improve with antibiotics or herbal antimicrobials alone
  • The importance of mould testing in persistent gut health conditions

Whether you’re a practitioner, health student, or someone navigating chronic gut symptoms, this episode provides valuable insight into the root causes of SIBO and the complex relationship between mould toxicity, gut dysfunction, inflammation, and the nervous system.

Tune in to discover why addressing mould exposure may be essential for long-term gut healing and digestive recovery.

Stay well,

Joanne Kennedy
