In this episode of The Histamine Well Podcast,  Joanne sits down with Rosaria Nithart, a French-based naturopath specializing in digestive health, to uncover the complexities of Hydrogen Sulfide SIBO—one of the most misunderstood forms of Small Intestinal Bacterial Overgrowth (SIBO).

Together, they break down how Hydrogen Sulfide SIBO differs from hydrogen- and methane-dominant SIBO, exploring the unique bacteria and biochemical pathways involved. Rosaria shares her step-by-step naturopathic framework for identifying, testing, and treating Hydrogen Sulfide SIBO naturally. The conversation also dives deep into the role of sulfur metabolism, oxalates, and molybdenum in managing symptoms and restoring gut balance.

Listeners will learn:

• The root causes and drivers behind Hydrogen Sulfide SIBO
• How to identify key symptoms and understand testing limitations
• The connection between sulfur, oxalates, and bacterial imbalances
• Practical treatment strategies that support gut healing without extreme diets
• How Hydrogen Sulfide SIBO links to UTIs, histamine intolerance, and detox pathways

Whether you’re a practitioner seeking deeper clinical insights or a patient navigating chronic gut issues, this episode offers a clear, actionable approach to understanding and managing Hydrogen Sulfide SIBO naturally.
