In this podcast, Emma Sutherland teams up with gut naturopath Matt Douglas to unravel the clinical complexity of small intestinal bacterial overgrowth (SIBO) - a condition that’s far more common and stubborn than many practitioners realise.

Together they dive deep into the pathophysiology, testing methods, and diagnostic challenges of SIBO, exploring why it’s often misdiagnosed and misunderstood. Matt brings a clear, practical approach to treatment - covering herbal antimicrobials including oregano, berberine, and allicin, the well-researched and clinically supported pharmaceutical option Rifaximin and his thoughts on dietary therapies like the Elemental Diet.

But the real value lies in his relapse prevention strategies, which emphasise the importance of motility agents and gut repair support — such as partially hydrolysed guar gum (PHGG), Saccharomyces boulardii, globe artichoke, and a proprietary six-herb combination — to help restore long-term digestive resilience.

Whether you’re new to SIBO or managing chronic cases, this is essential listening for practitioners ready to level up their gut health toolkit.
