What was done

This narrative review synthesized conceptual and clinical relationships between irritable bowel syndrome (IBS), other functional somatic syndromes (such as chronic fatigue syndrome and fibromyalgia), somatoform/somatic symptom disorders, and psychiatric conditions.

What was found

The abstract reports that IBS has substantial symptom overlap with other functional somatic syndromes and is associated with an increased prevalence of depression and anxiety. Approximately 50% of IBS patients report gastrointestinal symptoms alone without psychiatric comorbidity. No other quantitative data or effect sizes are provided in the abstract.

Why it matters

It highlights the multidimensional nature of IBS and argues for integrated collaborative care rather than dualistic organic-versus-mental classifications.

Limits

This is a narrative review without systematic search criteria, meta-analytic pooling, or reported sample sizes in the abstract.
