The Monash clinical study incorporated pre-recorded hypnotherapy sessions and showed significant results. A 2006 study found that pre-recorded hypnotherapy at home was an effective IBS treatment. An article published by peer-reviewed journal mHealth this year analysed the performance of a range of apps for depression, anxiety and schizophrenia. It found that apps can help significantly reduce depressive & anxiety symptoms, providing the greatest benefits for people with mild to moderate depression & anxiety.
There's significant evidence that gut-directed hypnotherapy can improve IBS symptoms. In 2016 Monash University found that gut-directed hypnotherapy can improve IBS symptoms by 70-80% in 3 out of 4 people, which was just as effective as the low FODMAP diet but without requiring diet change. An audit of 1000 patients who underwent gut-directed hypnotherapy found that it was an effective treatment for IBS.
