Summary

Stress is well known to affect visceral sensitivity and gastrointestinal function in general. A majority of patients with gastroesophageal reflux disease (GERD) report stress as an important factor triggering symptom exacerbation. A real-life stressor could exacerbate heartburn symptoms in GERD patients by enhancing perceptual response to esophageal acid exposure. In Irritable Bowel Syndrome (IBS) patients, visceral hypersensitivity is a major pathophysiological mechanism and stress is shown to trigger or exacerbate symptoms.

A possible mechanism of stress-induced visceral sensitivity could be the barrier dysfunction. Indeed, in a study performed by our group, in human, an acute psychological stressor induces hyperpermeability in a mast cell dependent fashion and exogenous peripheral corticotrophin-releasing hormone (CRH) recapitulated its effects on barrier function. This increase in intestinal permeability is a phenomenon which appears as a prerequisite for visceral hypersensitivity. Furthermore, few studies indicate that human intestinal motility is probably modulated by CRH. It has been shown that the brain-gut axis in IBS patients has an exaggerated response to CRH.To our knowledge, the acute effect of exogenous CRH on esophageal motility has not been studied before.
