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 GERD and Acid Reflux? Why Long-Term PPI Use Often Makes It Worse
GERD is rarely too much acid. It's lower esophageal sphincter dysfunction with pressure from SIBO, gastroparesis, vagal compromise, and bioenergetic failure. Long-term PPI use often perpetuates the underlying disease through rebound hypersecretion and SIBO induction.

What Actually Causes PCOS? A Mechanistic Reading of Polycystic Ovary Syndrome
PCOS is not primarily ovarian. Gut dysbiosis, insulin resistance, estrobolome dysfunction, mitochondrial failure, and the CD38-NAD+-SIRT3 cascade drive the disease. Birth control and metformin contain the readout while the upstream lesions persist.

What Actually Causes Fibromyalgia? The Mitochondrial, Mast Cell, and Small Fiber Neuropathy Mechanisms Standard Treatment Misses
Fibromyalgia has four upstream drivers: mitochondrial dysfunction, mast cell activation, small fiber neuropathy, and gut-brain axis dysfunction. Lyrica and Cymbalta act on central amplification, not on the peripheral lesions producing the input — which is why response is so often partial.

What Actually Causes Chronic Migraine? A Mechanistic Reading of Treatment-Resistant Migraine
Chronic migraine has four upstream drivers: mitochondrial bioenergetic failure, dural mast cell activation, gut-brain axis dysfunction, and hormonal-vasomotor instability. Most treatment-resistant cases (including CGRP antibody non-responders) need the dominant driver addressed at its upstream point.

Why Does Endometriosis Come Back After Surgery? The Gut, Estrobolome, and Bioenergetic Mechanism
Endometriosis recurs because excision removes lesions but not the substrate that selected for them. A mechanistic reading of the gut estrobolome, beta-glucuronidase-driven estrogen recirculation, LPS-driven inflammation, pelvic mast cell infiltration, mitochondrial dysfunction, and iron-driven oxidative damage — and why surgery and hormonal suppression contain the disease but rarely resolve it.

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.

What Actually Causes POTS? A Mechanistic Reading of Postural Orthostatic Tachycardia Syndrome
POTS is not one disease. Four mechanistically distinct pathways — post-viral autonomic ganglion dysfunction, gut-driven vagal dysregulation, connective-tissue-mediated venous pooling, and primary deconditioning — produce the same phenotype. Each needs different intervention. A Host Capacity Model stratification of why standard POTS treatment helps some patients and not others, and how to tell which pathway is dominant in a given case.

Why Am I So Tired When My Blood Work Is Normal? What Standard Testing Misses
Normal labs and persistent symptoms is not a contradiction. The lesion is usually in a layer the standard panel does not measure. A Host Capacity Model reading of why conventional blood work returns normal while chronic illness continues, the specific cellular, mitochondrial, gut, and autonomic mechanisms involved, and what testing actually catches what is missed.

Why Does MCAS Not Respond to Standard Treatment? The Four Mechanistically Distinct Patterns
Treatment-resistant MCAS is usually a stratification problem, not a stabilization problem. Four mechanistically distinct patterns produce the MCAS phenotype — barrier-driven, neuroimmune/vagal, chemical/toxicant, and clonal/KIT-driven — and they require different upstream interventions. A Host Capacity Model reading of why cromolyn, ketotifen, and the standard stack fail, and what stratification-anchored care looks like.

The Mycotoxin-Mitochondria Trap: Why Standard Detox Fails in Chronic Illness, and How to Escape It
