Gut-directed hypnotherapy is a structured form of hypnosis used in the context of digestive disorders, especially irritable bowel syndrome (IBS). A standardised IBS protocol was published by Olafur S. Palsson in 2006 as the North Carolina protocol. The Rome Foundation Working Team Report also includes gut-directed hypnotherapy within the broader group of brain-gut behavior therapies for disorders of gut-brain interaction

Yes. One of the early controlled IBS studies was published in The Lancet in 1984 by Peter J. Whorwell and colleagues under the title Controlled trial of hypnotherapy in the treatment of severe refractory irritable bowel syndrome. Later published work includes a large-scale audit by W.M. Gonsalkorale and colleagues in 2002, a long-term follow-up paper in 2003, a review by Simone L. Peters in 2015, and a randomised clinical trial by Simone L. Peters and colleagues in 2016.

Yes. The 1984 Whorwell paper was a controlled trial in severe refractory IBS. In 2016, Simone L. Peters, C.K. Yao, H. Philpott, G.W. Yelland, J.G. Muir, and P.R. Gibson published a randomised clinical trial titled the efficacy of gut-directed hypnotherapy is similar to that of the low FODMAP diet for the treatment of irritable bowel syndrome.

Some of the most frequently cited names in the IBS/GDH literature include Peter J. Whorwell, whose group published early controlled and follow-up studies; Olafur S. Palsson, who published the standardised North Carolina protocol; Simone L. Peters, who published a 2015 review and co-authored a 2016 randomised clinical trial; and Laurie Keefer and colleagues, whose 2022 Rome Foundation Working Team Report discusses brain-gut behavior therapies for disorders of gut-brain interaction.

Yes. In 1987, Peter J. Whorwell published a follow-up paper titled Hypnotherapy in severe irritable bowel syndrome. In 2003, W.M. Gonsalkorale and colleagues published Long term benefits of hypnotherapy for irritable bowel syndrome, which reported follow-up data extending to at least five years. A 2015 review by Simone L. Peters also concluded that gut-directed hypnotherapy has durable efficacy in patients with IBS.

Yes. A 2016 randomised clinical trial by Simone L. Peters and colleagues was titled the efficacy of gut-directed hypnotherapy is similar to that of the low FODMAP diet for the treatment of irritable bowel syndrome. On a public-facing page, the safest way to describe that study is simply to say that this comparison has been examined in a published randomised trial.

The Rome Foundation report says brain-gut behavior therapies are typically offered alongside medical therapies and only rarely as stand-alone alternatives. For that reason, it is safer and more accurate to describe gut-directed hypnotherapy as part of a broader care approach rather than as a replacement for medical assessment or treatment.

No. Published studies and reviews can tell us that gut-directed hypnotherapy has been studied in IBS, including in controlled trials, reviews, and long-term follow-up papers. They do not guarantee a particular individual outcome. A careful, accurate way to say this publicly is that gut-directed hypnotherapy has been studied in IBS and is discussed in published research and clinical reports, rather than claiming that it will definitely work for every person.
