Brain–Gut Interactions in Inflammatory Bowel Disease

Abstract

Psycho-neuro-endocrine-immune modulation through the brain-gut axis likely has a key role in the pathogenesis of inflammatory bowel disease (IBD). The brain-gut axis involves interactions among the neural components, including (1) the autonomic nervous system, (2) the central nervous system, (3) the stress system (hypothalamic-pituitary-adrenal axis), (4) the (gastrointestinal) corticotropin-releasing factor system, and (5) the intestinal response (including the intestinal barrier, the luminal microbiota, and the intestinal immune response). Animal models suggest that the cholinergic anti-inflammatory pathway through an anti-tumor necrosis factor effect of the efferent vagus nerve could be a therapeutic target in IBD through a pharmacologic, nutritional, or neurostimulation approach. In addition, the psychophysiological vulnerability of patients with IBD, secondary to the potential presence of any mood disorders, distress, increased perceived stress, or maladaptive coping strategies, underscores the psychological needs of patients with IBD. Clinicians need to address these issues with patients because there is emerging evidence that stress or other negative psychological attributes may have an effect on the disease course. Future research may include exploration of markers of brain-gut interactions, including serum/salivary cortisol (as a marker of the hypothalamic-pituitary-adrenal axis), heart rate variability (as a marker of the sympathovagal balance), or brain imaging studies. The widespread use and potential impact of complementary and alternative medicine and the positive response to placebo (in clinical trials) is further evidence that exploring other psycho-interventions may be important therapeutic adjuncts to the conventional therapeutic approach in IBD.

  • In IBD, chronic stress and HPA dysregulation worsen intestinal inflammation through neuroendocrine-immune interactions.

    “Bonaz (2013) highlighted that in IBD, chronic stress and HPA dysregulation worsen intestinal inflammation through neuroendocrine-immune interactions.”

    From Chronic Stress and Autoimmunity: The Role of HPA Axis and Cortisol Dysregulation (2025) · cites this paper as [66]

    The sections “Downregulation of the hypothalamic CRFergic system” and “Stress-induced brain-gut perturbations” describe neuroendocrine–immune pathways and report that chronic stress worsened experimental colitis. But the paper says a hyporeactive HPA axis in IBD *may* lead to colonic inflammation; it does not establish the claim’s unqualified causal conclusion in people with IBD. Page numbers were unavailable in our copy. (LLM, conf=0.86)

    Experimental — accuracy not yet measured
  • Excessive sympathetic or parasympathetic activity in the ANS can lead to dysregulation within the gut-brain axis contributing to maladaptive gastrointestinal responses and resulting in symptomatic flares.

    “Excessive sympathetic or parasympathetic activity in the ANS can lead to dysregulation within the gut-brain axis contributing to maladaptive gastrointestinal responses and resulting in symptomatic flares (8–12,14).”

    From Alterations in Heart Rate Variability Associated With Irritable Bowel Syndrome or Inflammatory Bowel Disease: A Systematic Review and Meta-Analysis (2021) · cites this paper as [11]

    The “Vagal inhibition” section (page unavailable) says stress increases sympathetic outflow and decreases vagal, or parasympathetic, outflow, favoring intestinal inflammation. “Stress and IBD” links stress to symptomatic flares. The paper does not support the claim that excessive parasympathetic activity contributes to flares; it describes reduced parasympathetic activity instead. (LLM, conf=0.88)

    Experimental — accuracy not yet measured
  • The interplay intensifies mucosal immune activation and disease flares.

    “This interplay intensifies mucosal immune activation and disease flares, suggesting stress pathway modulation as a therapeutic target [66].”
  • Heart rate variability provides an indirect measure of the autonomic nervous system.

    “Such monitoring might be achieved through a set of noninvasive electrocardiography parameters, collectively referred to as heart rate variability (HRV), that provides an indirect measure of the autonomic nervous system (ANS) (8–14).”
  • Gut inflammation may impact mental health and therapy response given the role of the brain-gut axis in pathobiology of IBD.

    “gut inflammation may impact mental health and therapy response given the role of the brain-gut axis in pathobiology of IBD (58).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
