In this study, 204 IBS patients treated with a course of hypnotherapy completed questionnaires about symptoms, quality of life, anxiety, and depression before, immediately after, and up to six years following the treatment. Of all the treated patients, 71% showed improvement in response to treatment initially, and of those, 81% were still fully improved when re-contacted up to five years later. Quality of life and anxiety or depression scores were also still significantly improved at follow-up but showed some deterioration. Patients also reported fewer doctor visits rates and less medication use long-term after hypnosis treatment. These results indicate that for most patients the benefits from hypnotherapy last at least five years.
BACKGROUND AND AIMS:
There is now good evidence from several sources that hypnotherapy can relieve the symptoms of irritable bowel syndrome in the short term. However, there is no long term data on its benefits and this information is essential before the technique can be widely recommended. This study aimed to answer this question.
PATIENTS AND METHODS:
204 patients prospectively completed questionnaires scoring symptoms, quality of life, anxiety, and depression before, immediately after, and up to six years following hypnotherapy. All subjects also subjectively assessed the effects of hypnotherapyretrospectively in order to define their "responder status".
71% of patients initially responded to therapy. Of these, 81% maintained their improvement over time while the majority of the remaining 19% claimed that deterioration of symptoms had only been slight. With respect to symptom scores, all items at follow up were significantly improved on pre-hypnotherapy levels (p<0.001) and showed little change from post-hypnotherapy values. There were no significant differences in the symptom scores between patients assessed at 1, 2, 3, 4, or 5+ years following treatment. Quality of life and anxiety or depression scores were similarly still significantly improved at follow up (p<0.001) but did show some deterioration. Patients also reported a reduction in consultation rates and medication use following the completion of hypnotherapy.
This study demonstrates that the beneficial effects of hypnotherapy appear to last at least five years. Thus it is a viable therapeutic option for the treatment of irritable bowel syndrome.
