Hypnotherapy and IBS: Implicit, long-term stress memory in the ENS?

Area of Science:

• Neurogastroenterology
• Psychosomatic Medicine
• Epigenetics

Background:

• Irritable Bowel Syndrome (IBS) is increasingly linked to psychiatric and mood disorders.
• Early life conditions (prenatal to early-age) may play a crucial role in IBS development.
• Subthreshold mental disorders (SMDs) are potential contributors to various diseases, including IBS.

Purpose of the Study:

• To explore the hypothesis that stress-induced implicit memories, persisting via epigenetic processes in the enteric nervous system (ENS), contribute to IBS.
• To review the efficacy of hypnosis in managing IBS and related conditions.

Main Methods:

• Literature review examining the connection between early life factors, stress, memory, epigenetics, and IBS.
• Analysis of studies investigating the impact of hypnosis on IBS symptoms and psychological well-being.

Main Results:

• Stress-induced implicit memories, potentially mediated by epigenetic changes in the ENS, are hypothesized to be key in IBS onset and maintenance.
• Hypnosis has demonstrated significant benefits in improving core IBS symptoms, as well as non-colonic symptoms like anxiety and depression.
• Hypnosis also enhances quality of life and cognitive function in IBS patients.

Conclusions:

• The association between IBS and mental health disorders may stem from fundamental early-life and stress-related mechanisms.
• Epigenetic modifications in the ENS could preserve stress-induced memories, contributing to IBS.
• Hypnosis offers a therapeutic avenue for IBS by potentially accessing and modulating unconscious brain processes.
