Gut-directed hypnotherapy long-term results: follow-up evidence

A fair question after a positive IBS trial is: does the benefit last? For gut-directed hypnotherapy, 12-month data are part of why the hub is graded A. Longer follow-up exists, but it is weaker as evidence.

Key evidence

Independent RCT programmes reported maintenance at about one year. The Flik 2014 review treated those courses as a class. The Gut psychological-therapies network meta-analysis is shorter-horizon by design.

Manchester-group observational follow-up (including work associated with Gonsalkorale) found that many initial responders still reported improvement years later, often with continued self-hypnosis. Those series do not have a matched untreated control at five years, so they cannot separate therapy from natural history.

Limitations

Completer bias is real: people who stay in touch may be the ones who did well. Booster-session practices vary and are not standardised across trials.

What we don't know yet

Follow-up beyond five years is thin. See open questions.
