In simple terms

IBS affects 10 to 15% of the population. No organic lesion, but very real symptoms. The FODMAP diet and mind-body approaches are game-changers.

What you need to remember

  • DiagnosisIBS is a diagnosis of exclusion based on Rome IV criteria:
  • Therapeutic ApproachesFODMAPs are fermentable sugars that worsen symptoms in 75% of IBS patients.

Irritable bowel syndrome (IBS) is a functional digestive disorder defined by chronic abdominal pain associated with bowel habit disturbances (diarrhea, constipation, or alternation of both).

Diagnosis

IBS is a diagnosis of exclusion based on Rome IV criteria:

  • Recurrent abdominal pain at least 1 day/week on average over the last 3 months
  • Associated with at least 2 of the following criteria: related to defecation, change in stool frequency, change in stool consistency

Therapeutic Approaches

Low FODMAP Diet

FODMAPs are fermentable sugars that worsen symptoms in 75% of IBS patients. The diet proceeds in 3 phases:

  1. Elimination (4-6 weeks): removal of high-FODMAP foods
  2. Reintroduction (6-8 weeks): individual testing of each group
  3. Personalization: long-term adapted diet

Mind-body approaches

  • Digestive hypnosis: efficacy demonstrated in several randomized trials
  • CBT (cognitive-behavioral therapy)
  • Yoga and mindfulness meditation

Symptomatic medications

  • Antispasmodics for pain
  • Osmotic laxatives or loperamide depending on transit profile
  • Selected probiotics (strain-specific)

IBS is not "all in your head." It's a gut-brain axis disorder with identified neurophysiological bases.
