Stress and the gut: pathophysiology, clinical consequences, diagnostic approach and treatment options.
Level 5 - mechanism / opinion, no new human data
Narrative review of mechanisms, diagnostics, and clinical management without systematic search criteria or primary data
What was done
This paper is a narrative review summarizing the pathophysiological mechanisms, clinical manifestations, diagnostic pathways, and therapeutic strategies associated with stress-induced alterations in the brain-gut axis.
What was found
The abstract reports no empirical measurements, effect sizes, or quantitative data. It outlines that stress impairs gastrointestinal motility, visceral sensitivity, secretion, mucosal blood flow, epithelial permeability, and microbiota composition, primarily mediated by mast cell activation and cytokine/neurotransmitter release. It also summarizes standard clinical workflows and multifactorial therapies for conditions like irritable bowel syndrome (IBS), gastroesophageal reflux disease, and peptic ulcers, noting potential protective roles for melatonin and probiotics.
Why it matters
It provides a broad framework connecting psychological and physiological stress to functional gastrointestinal pathology, reinforcing the rationale for multimodal management approaches that integrate behavioral, dietary, and pharmacological interventions.
Limits
The abstract contains no primary experimental or clinical data, no quantitative outcomes, and no description of systematic search or study selection methodologies. Findings represent expert synthesis and mechanistic reasoning rather than direct evidence from a defined study cohort.
