In this episode of Journal Club, we review:
Hydrogen Sulfide and Methane on Breath Test Correlate with Human Small Intestinal Hydrogen Sulfide Producers and Methanogens by Villanueva-Millan et al.
Sneak Peek of the Content
In this 1-hour conversation, we dive into new research from the REIMAGINE project — one of the first studies to directly link hydrogen sulfide (H₂S) and methane (CH₄) levels on breath testing with the actual microbes present in the small intestine.
Specifically, we cover:
✅ How hydrogen sulfide– and methane-producing microbes relate to stool consistency, motility, and IBS symptom patterns
✅ What these findings mean for interpreting SIBO and IMO breath test results in practice
✅ Why hydrogen sulfide “cut-offs” are still evolving — and how to apply emerging data without overstepping the evidence
✅ Practical implications for supporting clients with IBS, diarrhea, or constipation
As breath testing and microbial profiling continue to advance, this session offers timely insights to help dietitians interpret results with more confidence — and better connect gas patterns to what’s really happening in the small bowel.
A must-watch for dietitians managing clients with SIBO, IBS, and other functional gut disorders!
