Counterargument Library
The strongest published objections to the Host Capacity Model. Each entry shows where the argument is valid, what it challenges, how the framework responds, what remains unresolved, and the evidence that would settle it.
See also the Framework Audit and Claim Ledger.
What if dysbiosis is primary?
The Host Capacity Model treats dysbiosis as a downstream readout of host substrate state. A skeptical reader may argue dysbiosis is the primary disturbance.
Read full counterargument →What if antimicrobials work long term?
Some patients durably resolve recurrent SIBO with antimicrobials alone. The HCM framing of insufficient host capacity does not explain those cases.
Read full counterargument →What if MCAS is not gut-driven?
Many MCAS cases are genetic, structural, post-traumatic, or idiopathic — not driven by gut dysfunction.
Read full counterargument →What if long COVID symptoms are primarily vascular, neurological, or immune?
Long COVID has documented vascular, autonomic, and immune mechanisms. A gut-mediated framing may be incomplete or wrong for many patients.
Read full counterargument →What if butyrate supplementation fails despite intact host capacity?
Oral butyrate supplementation has produced inconsistent clinical results, which may seem to contradict the bioenergetic framing.
Read full counterargument →What if normal stool testing does not exclude mucosal dysfunction?
Stool tests have meaningful blind spots: mucosal-adherent communities, small-bowel content, and mucosal metabolic state may not be captured.
Read full counterargument →What if the Host Capacity Model overgeneralizes?
A single framework that attempts to explain SIBO, MCAS, and post-viral illness risks overreach.
Read full counterargument →What if symptoms are medication-driven?
Many GI, mast-cell-pattern, and fatigue symptoms can be produced or amplified by medications (PPIs, opioids, antibiotics, immunosuppressants, antidepressants, hormonal therapy).
Read full counterargument →What if the dominant driver is structural, endocrine, or autoimmune?
Strictures, adhesions, untreated thyroid disease, adrenal insufficiency, and autoimmune enteropathies can produce HCM-pattern symptoms while being a different problem entirely.
