In this episode of The Turd Nerds, Dr. Ilana Gurevich and Dr. Rebecca Sand sit down with Dr. Allison Siebecker, one of the leading voices in small intestinal bacterial overgrowth (SIBO), to break down some of the most exciting new SIBO research presented at Digestive Disease Week (DDW).
From emerging treatments for intestinal methanogen overgrowth (IMO) to new ways of making rifaximin more effective, Allison walks us through what may be coming next in SIBO treatment—and what clinicians can potentially use now. The conversation explores a new methane-targeting molecule designed to reduce methane production without killing methanogens, as well as research combining sustained-release N-acetylcysteine (NAC) with rifaximin to improve antibiotic delivery in the small intestine.
We also dive into surprising new research examining the relationship between methane and body weight, including evidence suggesting a U-shaped relationship between methane levels and BMI, with higher methane levels seen in both underweight and obese populations.
Finally, we take a closer look at new research on the elemental diet. Allison discusses impressive eradication rates for hydrogen SIBO, its effectiveness in methane-positive patients, and emerging evidence that elemental diets may reduce Candida while preserving beneficial small-intestinal commensal organisms.
In this episode, we explore:
• What’s coming next for methane/IMO treatment
• A new molecule that may suppress methane production without antibiotics
• Why sustained-release NAC may make rifaximin more effective
• Whether rifaximin doses could eventually be reduced
• The surprising connection between methane and BMI
• Why clinical observations sometimes precede published research
• New data on elemental diets for SIBO and IBS
• Elemental diets, Candida, and the small-intestinal microbiome
• When an elemental diet may be worth considering clinically
Whether you’re a clinician treating SIBO every day or someone struggling with recurrent SIBO or IMO, this episode offers a fascinating look at where SIBO research—and treatment—may be headed next.
