Why Dysbiosis, SIBO, Hydrogen Sulfide Intolerance, MCAS, and Long COVID May All Be Downstream of a Single Event
Dysbiosis, SIBO, hydrogen sulfide intolerance, MCAS, and long COVID may all be downstream of one event: the colonocyte losing control of oxygen, butyrate, and its own mitochondria. The Host Capacity Model in full.

What Actually Causes IBD? A Mechanistic Reading of Crohn's Disease and Ulcerative Colitis
IBD is not a single autoimmune disease. At the cellular level both Crohn's and ulcerative colitis are dominated by colonocyte bioenergetic failure — loss of butyrate oxidation, collapse of the gut oxygen gradient, and the inflammatory cascade that follows. A mechanistic reading anchored in primary research from Roediger 1990 onward, and why standard immunosuppression contains the response but does not restore the upstream lesion.

How Dysbiosis Disrupts Hormonal Health, Ovulation, and Egg Quality From the Inside Out
The fertility conversation has become overwhelmingly hormone-centric, but one of the most important mechanistic layers is still being underappreciated: the inflammatory dialogue between the gut microbiome and the ovary itself.

What I've Learned About Long COVID: A Gut-First Framework
I've spent the last few months diving deep into the long COVID literature, and something keeps jumping out at me: we've been looking at this disease from the wrong angle. Most discussions start with t

Why Some People Never Recover From Gut Disorders: The Overlooked Genetic Architecture Driving Butyrate Failure, Dysbiosis, and Chronic Symptoms
Most people still talk about SIBO, IBS, hydrogen sulfide overgrowth, or post-infectious gut dysfunction as if the microbiome alone is the entire story.
