Knox Hypothesis Series â Paper 3 Systemic Visceral Dysautonomia as a Disease-Modifying Substrate: A Hypothesis Linking Post-Viral Injury, Surgical Trauma, and Chronic Functional Disease
Abstract
Bruce H. Knox
Increasing attention has been directed toward the role of the autonomic nervous system in the development and persistence of chronic disease. While autonomic dysfunction has traditionally been examined within individual clinical conditions, a broader unifying framework may exist. This hypothesis paper proposes that systemic visceral dysautonomia can function as a disease-modifying substrate that links diverse pathological processes including post-viral injury, haemodynamic instability, surgical trauma, and chronic inflammatory disease.
The proposed model suggests that sequential physiological insults may induce a progressive state of autonomic priming, resulting in impaired vagal regulation of visceral organs. Once established, this dysregulated autonomic state may amplify inflammatory signalling, disrupt gastrointestinal motility, alter immune modulation, and increase vulnerability to functional disorders.
Drawing on emerging literature in neuroimmunology, autonomic physiology, and post-viral syndromes, this paper proposes a conceptual framework in which autonomic instability acts not as a primary disease but as an amplifying physiological environment capable of modifying disease expression across multiple organ systems.
The hypothesis provides a potential explanatory mechanism linking conditions such as eosinophilic oesophagitis, functional gastrointestinal disorders, dysautonomia syndromes, and post-viral autonomic instability. If validated through empirical investigation, this model may encourage a shift toward viewing autonomic regulation as a central component in chronic disease vulnerability.
