Brief Summary

This randomized, controlled trial (RCT) will evaluate the effectiveness of gut-directed hypnotherapy for management of Irritable Bowel Syndrome (IBS) in individuals diagnosed with Ehlers-Danlos Syndromes or Generalized Hypermobility Spectrum Disorders (G-HSD). Consenting patients recruited from the Toronto General Hospital GoodHope Ehlers-Danlos Syndrome Clinic will be randomly assigned to one of two groups: (1) standard medical therapy or (2) standard medical therapy plus eight sessions of gut-directed hypnotherapy. The main questions this study will answer are:

  1. 1.Is gut-directed hypnotherapy an efficacious treatment for IBS symptoms among individuals with EDS or G-HSD?
  2. 2.Does gut-directed hypnotherapy improve other gut symptoms, quality of life, visceral sensitivity, and emotional distress?
  3. 3.Is the activity of the parasympathetic nervous system (i.e. the body's "rest and digest" system) associated with IBS symptoms or treatment outcomes among individuals with EDS or G-HSD?

Outcome Measures

Primary Outcomes (1)

  • IBS Symptom Severity

    The IBS Symptoms Severity Score (IBS-SSS) is a 5-item measure that asks participants to rate abdominal pain intensity, abdominal distension, dissatisfaction with bowel habits, and IBS life interference on a 0-100 scale. The IBS-SSS is a validated measure of IBS symptom severity and a recommended outcome measure for IBS treatment trials

    Immediately post-treatment, 3-months post-treatment

Secondary Outcomes (4)

  • Upper Gastrointestinal Symptoms

    Immediately post-treatment, 3-months post-treatment

  • IBS-related Quality of Life

    Immediately post-treatment, 3-months post-treatment

  • Visceral Sensitivity

    Immediately post-treatment, 3-months post-treatment

  • Emotional Distress

    Immediately post-treatment, 3-months post-treatment

Other Outcomes (1)

  • Weekly Ratings of GI Health and Medication Use

    Once a week for 9 weeks hypnotherapy treatment

Study Arms (2)

Standard Medical Therapy

OTHER

Standard Medical Treatment will be administered by board certified gastroenterologists through the EDS Clinic gastroenterology clinical care pathway. Therapies will be individualized to the participants' current symptoms and severity of symptoms as per current clinical guidelines for management of IBS. Potential therapies that may be administered include dietary changes, supplemental fibre, and pharmacotherapy (including neuromodulators) as appropriate.

Other: Standard Medical Therapy

Standard Medical Therapy plus Gut-Directed Hypnotherapy

EXPERIMENTAL

In addition to Standard Medical Therapy, participants randomized to this arm will attend 8 sessions of gut-directed hypnotherapy by a trained behavioral therapist. The treatment protocol developed for the proposed study was adapted from the empirically-supported Manchester Protocol for gut-directed hypnotherapy. At each visit, a voluntary, pleasant, and dream-like state of deep relaxation will be induced and suggestions made for greater relaxation, abdominal comfort, and normalization of gut function. The first session will be 90 minutes in duration and the remaining sessions will be 60 minutes. At the first session, participants will be provided with 30 minutes of education on the nature of the gut-brain axis and hypnotherapy before they undergo hypnotherapy.

Behavioral: Gut-directed hypnotherapyOther: Standard Medical Therapy

Interventions

Eight session gut-directed hypnotherapy for IBS symptoms adapted from the evidence-based Manchester protocol for treatment of IBS.
