Gut-directed hypnotherapy for IBS-M: evidence review

Moderate evidence

Mixed IBS is well represented in GDH trials as part of the global-symptom evidence. Dedicated IBS-M endpoints are scarce.

Last reviewed 27 August 2026

Mixed-stool IBS (IBS-M) is common in clinic and in older trial samples that did not split subtypes cleanly. Global improvement data apply, but “less switching” is rarely a primary outcome.

Key evidence

Treat the programme-level evidence as the main signal. Subtype pages exist so we do not pretend IBS-D, IBS-C, and IBS-M are equally measured.

Limitations

Rome IV mixed criteria are newer than much of the Manchester literature.

What we don't know yet

Whether GDH reduces subtype switching is not established.
