Send us Fan Mail

In this episode of The Gut Health Dialogues Podcast, Alyssa Simpson sits down with her client Doug, who shares his powerful journey from being house-bound and limited to a “safe” diet of chicken and rice, to reclaiming his gut health, his confidence, and his life.

What started as a frustrating case of “IBS with no answers” turned out to be Hydrogen Sulfide SIBO, a form of small intestinal bacterial overgrowth that’s often missed on standard breath tests and misdiagnosed as IBS, anxiety, or stress.

Alyssa and Doug unpack what it really takes to identify and treat this overlooked condition, from testing and dietary strategy to motility support and rebuilding tolerance, showing that recovery is not only possible, it’s life-changing.
