Gut Barrier and Dysbiosis — Foundational Reference The gut system is the second major constitutional factor in this clinical picture. It is tightly coupled to the CNS system through the gut-vagus connection and through continuous inflammatory signaling originating at the intestinal barrier. LPS translocation increases the inflammatory load while the compromised vagal anti-inflammatory pathway can … Read more

Iron-Triggered Dysbiosis and Locked Attractor State This document presents a case-based analytical framework, supported by temporal, microbiological, and clinical evidence, for the following: two high-dose intravenous iron infusions in late 2023 and early 2024 acted as the proximate trigger for catastrophic and durable gut microbiome collapse in a host with pre-existing constitutional vulnerability. The collapse … Read more
Helminthic Therapy — Personal Reference Necator americanus (human hookworm) colonization has been maintained since August 2020. This document covers its mechanism relevant to this patient’s picture, clinical response history, the impact of the 2024 dysbiosis event on efficacy, current status, and its relationship to vagus nerve stimulation as a parallel intervention. Mechanism Helminthic therapy operates … Read more
The Root Cause Protocol (RCP) promises a hidden “real” explanation for chronic illness through minerals and metabolism. It attracts many people who have been failed by conventional medicine and who appreciate the use of natural healing practices.
However, this protocol’s sweeping claims and one-size-fits-all approach can and does cause real harm to many.
Pernicious anemia is one of the clearest cases in contemporary medicine where everything required for good outcomes exists — the diagnostic tools, the treatment, the evidence base — and the outcomes remain poor anyway. The gap between what medicine knows and what medicine does is not a gap in knowledge.
How a 19th-Century Disease Model Still Shapes Modern Care Pernicious anemia has been misunderstood since it was first described. That misunderstanding did not persist because of a lack of scientific progress, but because early observations hardened into a disease model that medicine never fully revised. The result is a condition that remains misdiagnosed, underdiagnosed, and … Read more
