Gut-directed hypnotherapy for IBS-D: evidence review

Moderate evidence

GDH trials include many people with diarrhoea-predominant IBS. Global improvement is clearer than a dedicated IBS-D meta-analysis.

Last reviewed 27 August 2026

Diarrhoea-predominant IBS (IBS-D) is common in gut-directed hypnotherapy samples. Urgency and loose stools are among the symptoms global scales capture. A dedicated IBS-D-only evidence grade is still B, not a second Grade A.

Key evidence

Pooled GDH reviews such as Flik 2014, and the Gut psychological-therapies NMA report global IBS outcomes. Many included participants had diarrhoea-predominant or mixed patterns. That supports offering GDH to people with IBS-D after medical assessment. It does not replace an IBS-D-specific network meta-analysis.

See the hub for the programme-level Grade A.

Limitations

Trials often under-report stool-form subscales. People with overlapping bile-acid diarrhoea or microscopic colitis should have those considered medically first.

What we don't know yet

Whether urgency responds as reliably as pain is not cleanly separated in most papers.
