In this episode, Dr. Eric sits down with gut health expert Lindsey Parsons to explore the deeper root causes behind SIBO—especially post-infectious IBS. Lindsey shares her personal journey from food poisoning to chronic gut issues and autoimmune conditions, eventually leading her to specialize in helping others heal complex digestive disorders.

They dive into what really drives recurrent SIBO, explaining how an autoimmune response triggered by food poisoning can damage the migrating motor complex, leading to ongoing bacterial overgrowth. Lindsey breaks down the differences between hydrogen and methane SIBO, the role of fungal overgrowth (SIFO), and why many traditional approaches fail to provide lasting results. The conversation also covers testing options like the IBS Smart test, limitations of breath testing, and how to better assess the gut microbiome.

You’ll also learn about effective treatment strategies, including when to use antibiotics versus herbal antimicrobials, the emerging use of MSM, the controversy around berberine, and the critical role of prokinetics in long-term management. If you want a clearer, more balanced understanding of why SIBO keeps coming back and how to manage it effectively, you’ll get a lot out of this episode.
