Irritable bowel syndrome (IBS) may involve organic diseases, challenging the brain-gut model. Research highlights potential causes like inflammation, serotonin issues, and bacterial overgrowth, suggesting future disease-modifying therapies for IBS.

Area of Science:

  • Gastroenterology
  • Neurogastroenterology
  • Internal Medicine

Background:

  • The traditional view of Irritable Bowel Syndrome (IBS) as a purely functional brain-gut disorder is increasingly challenged.
  • Emerging evidence suggests identifiable organic pathologies in a subset of IBS patients meeting Rome criteria.

Purpose of the Study:

  • To review recent advances in understanding the pathophysiology of IBS.
  • To discuss current and future management strategies for IBS.

Main Methods:

  • Literature review of recent research on IBS pathophysiology and management.
  • Analysis of evidence for organic diseases and novel therapeutic approaches.

Main Results:

  • Increasing evidence supports organic causes in IBS, including subtle inflammatory bowel disease, serotonin dysregulation, bacterial overgrowth, and central dysregulation.

  • Post-infectious IBS is a recognized entity, and a genetic contribution is likely.
  • Coeliac disease mimicking IBS requires heightened diagnostic awareness.

    • Conclusions:

    • The pathophysiology of IBS is complex, with organic factors playing a significant role.
    • Current IBS management is primarily symptomatic, but disease-modifying therapies are anticipated.
    • Future research should focus on identifying specific organic causes and developing targeted treatments for IBS subtypes.
