Irritable Bowel Syndrome, IBS, is estimated to effect up to 20% of the population in the U.S., of those effected, 67% are women. By comparison, only 9.5% of people are affected by depression and 7% by diabetes.
IBS is a chronic, functional, gastrointestinal disorder characterized by diarrhea, constipation, bloating, abdominal pain, gas, and spasms. These may be present singly or in combinations. It is persistent and cyclical, not life threatening, and there is no known cause.
While IBS is not life threatening, it can have a significant effect on a person's quality of life. IBS is the second most cited reason for missed work days in the U.S., causing lack of promotions, changed jobs, and unemployment (Source: Digestion, 1999, B.A. Hahn, et al).
IBS patients account for 10% of all primary care physician visits and 50-55% of all gastroenterologists visits. IBS sufferers incur 74% more health care costs than do non-IBS sufferers (Source: Gastroenterology, 1995, Talley, et al)
In addition, the levels of discomfort and psychological effects this disorder creates can not be overlooked. IBS sufferers often are also diagnosed with depression and anxiety, as well as autonomic nervous system issues, i.e. fibromyalgia, dyspepsia.

Whorwell PJ; Prior A; Faragher EB. Controlled trial of hypnotherapy in the treatment of severe refractory irritable-bowel syndrome.The Lancet 1984, 2: 1232-4.
This study is the earliest and perhaps the best study in this research area to date, as it was thoroughly placebo-controlled and showed dramatic contrast in response to hypnosis treatment above the placebo group. Thirty patients with severe symptoms unresponsive to other treatment were randomly chosen to receive 7 sessions of hypnotherapy (15 patients) or 7 sessions of psychotherapy plus placebo pills (15 patients). The psychotherapy group showed a small but significant improvement in abdominal pain and distension, and in general well-being but not bowel activity pattern. The hypnotherapy patients showed a dramatic improvement in all central symptom. The hypnotherapy group showed no relapses during the 3-month follow-up period.

Whorwell PJ; Prior A; Colgan SM. Hypnotherapy in severe irritable bowel syndrome: further experience. Gut, 1987 Apr, 28:4, 423-5. This report summed up further experience with 35 patients added to the 15 treated with hypnotherapy in the 1984 Lancet study. For the whole 50 patient group, success rate was 95% for classic IBS cases, but substantially less for IBS patients with atypical symptom picture or significant psychological problems. The report also observed that patients over age 50 seemed to have lower success rate from this treatment.

This study employed a shorter hypnosis treatment course than other studies for IBS, and the success rate was lower, most likely demonstrating that a larger number of sessions is necessary for optimal benefit. Twenty out of 33 patients with refractory irritable bowel syndrome treated with four sessions of hypnotherapy in this study improved. Improvement was maintained at a 3-month treatment.

This study compared 25 severe IBS patients treated with hypnosis to 25 patients with similar symptom severity treated with other methods, and demonstrated that in addition to significant improvement in all central IBS symptoms, hypnotherapy recipients had fewer visits to doctors, lost less time from work than the control group and rated their quality of life more improved. Those patients who had been unable to work prior to treatment resumed employment in the hypnotherapy group but not in the control group. The study quantifies the substantial economic benefits and improvement in health-related quality of life which result from hypnotherapy for IBS on top of clinical symptom improvement. Koutsomanis D.

Am J Gastroenterol 2002 Apr;97(4):954-61. This study is notable as the largest case series of IBS patients treated with hypnosis and reported on to date. 250 unselected IBS patients were treated in a clinic in Manchester, England, using 12 sessions of hypnotherapy over a 3-month period plus home practice between sessions. Marked improvement was seen in all IBS symptoms (overall IBS severity was reduced by more than half on the average after treatment), quality of life, and anxiety and depression. All subgroups of patients appeared to do equally well except males with diarrhea, who improved far less than other patients for unknown reason.

Possible physiological and psychological mechanisms of hypnosis treatment for IBS were investigated in two studies. Patients with severe IBS received seven biweekly hypnosis sessions and used hypnosis audiotapes at home. Rectal pain thresholds and smooth muscle tone were measured with a barostat before and after treatment in 18 patients (study I), and treatment changes in heart rate, blood pressure, skin conductance, finger temperature, and forehead electromyographic activity were assessed in 24 patients (study II). Somatization, anxiety, and depression were also measured. All central IBS symptoms improved substantially from treatment in both studies. Rectal pain thresholds, rectal smooth muscle tone, and autonomic functioning (except sweat gland reactivity) were unaffected by hypnosis treatment. However, somatization and psychological distress showed large decreases. In conclusion, hypnosis improves IBS symptoms through reductions in psychological distress and somatization. Improvements were unrelated to changes in the physiological parameters measured. 17 of 18 patients in study 1 and 21 of 24 patients in study 2 were judged substantially improved Improvement was well-maintained at 10-12 month follow up in study 2.

This study evaluated the rectal sensitivity changes in IBS patients who received hypnotherapy, like a previous study by the same group (see Houghton et al's study above, but using a slightly different methodology. Twenty-three IBS patients were tested before and after 12 weeks of hypnotherapy. Following the course of hypnotherapy, the mean pain sensory threshold increased in the hypersensitive subgroup and tended to decrease in the hyposensitive group, although the l. Reduction in gut pain sensitivity was associated with a reduction in abdominal pain. These results suggest that hypnotherapy may work at least partly by normalizing bowel perception in those patients who have abnormal gut sensitivity, while leaving normal sensation unchanged.

Cognitive change in patients undergoing hypnotherapy for irritable bowel syndrome.Cognitive changes were evaluated in 78 IBS patients who completed a 12-session hypnosis treatment course, using the recently developed Cognitive Scale for Functional Bowel Disorders. Hypnotherapy resulted in improvement of symptoms, quality of life, anxiety and depression. Unhelpful IBS-related cognitions improved significantly, with reduction in the total cognitive score and all component themes related to bowel function. Overall symptom reduction correlated with an improvement on the cognitive scale.
Gonsalkorale WM, Miller V, Afzal A, Whorwell PJ. Long term benefits of hypnotherapy for irritable bowel syndrome. Gut. 2003 Nov;52(11):1623-9. In this study, 204 IBS patients treated with a course of hypnotherapy completed questionnaires scoring symptoms, quality of life, anxiety, and depression before, immediately after, and up to six years following treatment. 71% of patients showed improvement in response to treatment initially, and of those, 81% were still improved years later, while most of the other 19% only reported slight worsening of symptoms. 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.
Psychosom Med. 2004 Mar-Apr;66(2):233-8 Treatment with hypnotherapy reduces the sensory and motor component of the gastrocolonic response in irritable bowel syndrome. Simren M, Ringstrom G, Bjornsson ES, Abrahamsson H.
Department of Internal Medicine, Sahlgrenska University Hospital, Goteborg, Sweden. magnus.simren@medicine.gu.se OBJECTIVE: Postprandial symptoms in irritable bowel syndrome are common and relate to an exaggerated motor and sensory component of the gastro colonic response. We investigated whether this response can be affected by hypnotherapy. METHODS: We included 28 patients with irritable bowel syndrome refractory to other treatments. They were randomized to receive gut-directed hypnotherapy 1 hour per week for 12 weeks (N = 14) or were provided with supportive therapy (control group; N = 14). Before randomization and after 3 months, all patients underwent a colonic distension trial before and after a 1-hour duodenal lipid infusion. Colonic sensory thresholds and tonic and phasic motor activity were assessed. RESULTS: Before randomization, reduced thresholds after vs. before lipid infusion were seen in both groups for all studied sensations. At 3 months, the colonic sensitivity before duodenal lipids did not differ between groups. Controls reduced their thresholds after duodenal lipids for gas (22 +/- 1.7 mm Hg vs. 16 +/- 1.6 mm Hg, p <.01), discomfort (29 +/- 2.9 mm Hg vs. 22 +/- 2.6 mm Hg, p <.01), and pain (33 +/- 2.7 mm Hg vs. 26 +/- 3.3 mm Hg, p <.01), whereas the hypnotherapy group reduced their thresholds after lipids only for pain (35 +/- 4.0 mm Hg vs. 29 +/- 4.7 mm Hg, p <.01). The colonic balloon volumes and tone response at randomization were similar in both groups. At 3 months, baseline balloon volumes were lower in the hypnotherapy group than in controls (83 +/- 14 ml vs. 141 +/- 15 ml, p <.01). In the control group, reduced balloon volumes during lipid infusion were seen (141 +/- 15 ml vs. 111 +/- 19 ml, p <.05), but not after hypnotherapy (83 +/- 14 ml vs. 80 +/- 16 ml, p >.20). CONCLUSION: Hypnotherapy reduces the sensory and motor component of the gastro colonic response in patients with irritable bowel syndrome. These effects may be involved in the clinical efficacy of hypnotherapy in IBS.
Am J Clin Hypn. 2005 Jan;47(3):161-78. Hypnosis and irritable bowel syndrome: a review of efficacy and mechanism of action. Tan G, Hammond DC, Joseph G. Michael E. DeBakey VA Medical Center, Baylor College of Medicine, Houston, TX 77030, USA. tan.gabriel@med.va.gov Irritable bowel syndrome (IBS) is a functional gastrointestinal disorder characterized by abdominal pain, distension, and an altered bowel habit for which no cause can be found. Despite its prevalence, there remains a significant lack of efficacious medical treatments for IBS to date. In this paper we reviewed a total of 14 published studies (N=644) on the efficacy of hypnosis in treating IBS (8 with no control group and 6 with a control group). We concluded that hypnosis consistently produces significant results and improves the cardinal symptoms of IBS in the majority of patients, as well as positively affecting non-colonic symptoms. When evaluated according to the efficacy guidelines of the Clinical Psychology Division of American Psychological Association, the use of hypnosis with IBS qualifies for the highest level of acceptance as being both efficacious and specific. In reviewing the research on the mechanism of action as to how hypnosis works to reduce symptoms of IBS, some evidence was found to support both physiological and psychological mechanisms of action.

University of North Carolina at Chapel Hill, Chapel Hill, North Carolina 27599, USA. William_Whitehead@med.unc.edu Irritable bowel syndrome (IBS) is a complex and prevalent functional gastrointestinal disorder that is treated with limited effectiveness by standard medical care. Hypnosis treatment is, along with cognitive-behavioral therapy, the psychological therapy best researched as an intervention for IBS. Eleven studies, including 5 controlled studies, have assessed the therapeutic effects of hypnosis for IBS. Although this literature has significant limitations, such as small sample sizes and lack of parallel comparisons with other treatments, this body of research consistently shows hypnosis to have a substantial therapeutic impact on IBS, even for patients unresponsive to standard medical interventions. The median response rate to hypnosis treatment is 87%, bowel symptoms can generally be expected to improve by about half, psychological symptoms and life functioning improve after treatment, and therapeutic gains are well maintained for most patients for years after the end of treatment.
Gut. 2002 Nov;51(5):701-4. Visceral sensation and emotion: a study using hypnosis. Houghton LA, Calvert EL, Jackson NA, Cooper P, Whorwell PJ. Department of Medicine, University Hospital of South Manchester, Manchester M20 2LR, UK. lahoughton@man.ac.uk BACKGROUND AND OBJECTIVES: We have previously shown that hypnosis can be used to study the effect of different emotions on the motility of the gastrointestinal tract. These studies demonstrated that both anger and excitement increased colonic motility while happiness led to a reduction. The purpose of this study was to investigate the effect of hypnotically induced emotion on the visceral sensitivity of the gut. METHODS: Sensory responses to balloon distension of the rectum and compliance were assessed in 20 patients with irritable bowel syndrome (IBS) (aged 17-64 years; 17 female) diagnosed by the Rome I criteria. Patients were studied on four separate occasions in random order either awake (control) or in hypnosis, during which anger, happiness, or relaxation (neutral emotion) were induced. RESULTS: Hypnotic relaxation increased the distension volume required to induce discomfort (p=0.05) while anger reduced this threshold compared with relaxation (p<0.05), happiness (p<0.01), and awake conditions (p<0.001). Happiness did not further alter sensitivity from that observed during relaxation. There were no associated changes in rectal compliance or wall tension. CONCLUSIONS: Further to our previous observations on motility, this study shows that emotion can also affect an IBS patient's perception of rectal distension and demonstrates the critical role of the mind in modulating gastrointestinal physiology. These results emphasise how awareness of the emotional state of the patient is important when either measuring visceral sensitivity or treating IBS.
Gastroenterol Clin North Am. 1991 Jun;20(2):325-33. Treatment of the irritable bowel syndrome. Friedman G. Department of Medicine, Mt. Sinai School of Medicine, New York, New York. Individualization of treatment for patients with IBS is predicated on a thorough analysis of the patient's symptoms, consideration of the reasons for seeking health care, evaluation of symptom-precipitating factors, elimination of confounding features, and the absolute knowledge of the absence of organic illness. Collecting and codifying appropriate historical data allow the physician to educate the patient with respect to the origin of his symptoms, and to enlist the patient as a partner in his future health care. There is no single, universally accepted therapeutic agent available for the treatment of the IBS patient. As a result, treatment is directed at reducing the frequency and intensity of triggering factors as well as ameliorating the symptoms when they arise. Symptoms evoked by psychologic factors may be effectively reduced by psychotherapy or hypnotherapy. Situational anxiety may be treated for brief periods by using antianxiety agents such as diazepam, chlordiazepoxide, buspirone, or similar agents. Depressive reactions may be reduced with suitable doses of antidepressant agents such as amitriptyline. Smooth muscle hyperreactivity may be dulled with small amounts of selected anticholinergics, which are usually most effective in reducing meal-induced discomfort. Peppermint oil may be of additional benefit. Gas-related symptoms require elimination of contributory dietary factors, such as lactose-containing foods, sorbitol, or fructose, as well as certain oligosaccharides. Simethecone, charcoal, or beanase may be helpful. Functional constipation is best treated with graded doses of insoluble or soluble fiber. Diarrheal episodes may be reduced with either loperamide or diphenoxylate. Careful, continued follow-up assessment of therapeutic endeavors, a sincere interest in the patient's concerns, and surveillance for intercurrent organic illness are the cornerstones of complete ongoing care.
Curr Treat Options Gastroenterol. 1999 Feb;2(1):13-19 Irritable Bowel Syndrome. Wald A. University of Pittsburgh Medical Center, Pittsburgh University Hospital, Mezzanine Level, C-Wing, 200 Lothrop Street, Pittsburgh, PA 15213-2582. I believe there are four essential elements in the management of patients with irritable bowel syndrome (IBS): to establish a good physician-patient relationship; to educate patients about their condition; to emphasize the excellent prognosis and benign nature of the illness; and to employ therapeutic interventions centering on dietary modifications, pharmacotherapy, and behavioral strategies tailored to the individual. Initially, I establish the diagnosis, exclude organic causes, educate patients about the disease, establish realistic expectations and consistent limits, and involve patients in disease management. I find it critical to determine why the patient is seeking assistance (eg, cancer phobia, disability, interpersonal distress, or exacerbation of symptoms). Most patients can be treated by their primary care physician. However, specialty consultations may be needed to reinforce management strategies, perform additional diagnostic tests, or institute specialized treatment. Psychological co-morbidities do not cause symptoms but do affect how patients respond to them and influence health care-seeking behavior. I find that these issues are best explored over a series of visits when the physician-patient relationship has been established. It can be helpful to have patients fill out a self-administered test to identify psychological co-morbidities. I often use these tests as a basis for extended inquiries into this area, resulting in the initiation of appropriate therapies. I encourage patients to keep a 2-week diary of food intake and gastrointestinal symptoms. In this way, patients become actively involved in management of their disease, and I may be able to obtain information from the diary that will be valuable in making treatment decisions. I do not believe that diagnostic studies for food intolerances are cost-effective or particularly helpful; however, exclusion diets may be beneficial. I introduce fiber supplements gradually and monitor them for tolerance and palatability. Synthetic fiber is often better-tolerated than natural fiber, but must be individualized. In my experience, excessive fiber supplementation often is counterproductive, as abdominal cramps and bloating may worsen. Antidiarrheal agents are very effective when used correctly, preferably in divided doses. I use them in patients in anticipation of diarrhea and especially in those who fear symptoms when engaged in activities outside the home. I encourage patients to make decisions as to when and how much to use. However, almost always, a morning dose before breakfast is used (loperamide, 2 to 6 mg) and, perhaps again later in the day when symptoms of diarrhea are prominent. I prefer antispasmodics to be used intermittently in response to periods of increased abdominal pain, cramps, and urgency. For patients with daily symptoms, especially after meals, agents such as dicyclomine before meals are useful. For patients with infrequent but severe episodes of unpredictable pain, sublingual hyoscyamine often produces rapid relief and instills confidence. In general, I recommend that oral antispasmodics be used for a limited period of time rather than indefinitely, and generally for periods of time when symptoms are prominent. For chronic visceral pain syndromes, I recommend small doses of tricyclic antidepressants. These agents are especially effective in diarrhea-predominant patients with disturbed sleep patterns but may be unacceptable to patients with constipation. I educate patients that side effects occur early and benefits may not be apparent for 3 to 4 weeks. I consider using SSRIs in low doses in patients with constipation-predominant IBS; cisapride, 10 to 20 mg three times per day, also may be beneficial. When taken with drugs that inhibit cytochrome P450, cisapride has been associated with serious cardiac arrhythmias caused by QT prolongation, including ventricular arrhythmias and torsades de pointes. These drugs include the azole fungicides; erythromycin, clarithromycin, and troleandomycin; some antidepressants; HIV protease inhibitors; and others. In patients with IBS with mild to moderate co-morbid depression, I have found that the use of SSRIs such as paroxetine, fluoxetine, or sertraline may be beneficial. It is important to tell patients that anxiety and disturbed sleep may occur during the first 10 days and benefits may not occur for 3 to 4 weeks. I prescribe a small amount of a short-acting benzodiazepine such as alprazolam, 0.5 mg two times per day, to control these symptoms. For generalized anxiety without depression, buspirone or clonazepam may be useful. I have found that patients who also have associated panic disorder may benefit from a benzodiazepine, tricyclic antidepressant, or an SSRI. However, these patients are best managed in conjunction with a psychiatrist or psychologist. I consider the use of alternative therapies in patients who fail to respond to conventional measures and who are receptive to alternative strategies. These include general relaxation techniques such as biofeedback and hypnosis therapies.
J Clin Nurs. 2006 Jun;15(6):678-84 Effect of nurse-led gut-directed hypnotherapy upon health-related quality of life in patients with irritable bowel syndrome. Smith GD. School of Health in Social Science, University of Edinburgh, Old Medical School, Edinburgh, UK. graeme.smith@ed.ac.uk AIMS AND OBJECTIVES: This study quantified health-related quality of life in a group of irritable bowel syndrome patients and measures changes following a treatment programme of nurse-led gut-directed hypnotherapy. BACKGROUND: It is well recognized that health-related quality of life can be severely impaired in patients suffering form the irritable bowel syndrome. Current conventional treatment for irritable bowel syndrome is often unsatisfactory. In contrast it has been shown that gut-directed hypnotherapy is an effective treatment of irritable bowel syndrome with up to three-quarters of patients reporting symptomatic improvement. DESIGN/METHOD: Seventy-five patients (55 females/20 males, median age 37.1 years, age range 18-64) comprised the study group. Physical symptoms of irritable bowel syndrome were recorded using seven-day diary cards. On presentation the predominant symptoms were abdominal pain (61%), altered bowel habit (32.5%), and abdominal distension/bloating (6.5%) in the patient group. An irritable bowel syndrome quality of life questionnaire was used to define health-related quality of life. Psychological well-being was measured using the Hospital Anxiety and Depression Scale. Data analysis was carried out using MINITAB, Release 12 for Windows. RESULTS: Physical symptoms statistically improved after hypnotherapy. There were also significant statistical improvements (P < 0.001) in six of the eight health-related quality of life domains measured (emotional, mental health, sleep, physical function, energy and social role). These improvements were most marked in female patients who reported abdominal pain as their predominant physical symptom. Anxiety and depression improved following treatment. CONCLUSION: Gut-directed hypnotherapy has a very positive impact on health-related quality of life with improvements in psychological well-being and physical symptoms. It appears most effective in patients with abdominal pain and distension. Relevance to clinical practice. This study demonstrates that by integrating complementary therapies into conventional care that gastrointestinal nurses have a potential role in the management of irritable bowel syndrome.

Vlieger AM, Menko-Frankenhuis C, Wolfkamp SC, Tromp E, Benninga MA. Department of Pediatrics, St. Antonius Hospital, Nieuwegein, The Netherlands. a.vlieger@antonius.net BACKGROUND & AIMS: Functional abdominal pain (FAP) and irritable bowel syndrome (IBS) are highly prevalent in childhood. A substantial proportion of patients continues to experience long-lasting symptoms. Gut-directed hypnotherapy (HT) has been shown to be highly effective in the treatment of adult IBS patients. We undertook a randomized controlled trial and compared clinical effectiveness of HT with standard medical therapy (SMT) in children with FAP or IBS. METHODS: Fifty-three pediatric patients, age 8-18 years, with FAP (n = 31) or IBS (n = 22), were randomized to either HT or SMT. Hypnotherapy consisted of 6 sessions over a 3-month period. Patients in the SMT group received standard medical care and 6 sessions of supportive therapy. Pain intensity, pain frequency, and associated symptoms were scored in weekly standardized abdominal pain diaries at baseline, during therapy, and 6 and 12 months after therapy. RESULTS: Pain scores decreased significantly in both groups: from baseline to 1 year follow-up, pain intensity scores decreased in the HT group from 13.5 to 1.3 and in the SMT group from 14.1 to 8.0. Pain frequency scores decreased from 13.5 to 1.1 in the HT group and from 14.4 to 9.3 in the SMT group. Hypnotherapy was highly superior, with a significantly greater reduction in pain scores compared with SMT (P < .001). At 1 year follow-up, successful treatment was accomplished in 85% of the HT group and 25% of the SMT group (P < .001). CONCLUSIONS: Gut-directed HT is highly effective in the treatment of children with longstanding FAP or IBS. PMID: 17919634 [PubMed - indexed for MEDLINE]

Possible physiological and psychological mechanisms of hypnosis treatment for IBS were investigated in two studies. Patients with severe IBS received seven biweekly hypnosis sessions and used hypnosis audiotapes at home. Rectal pain thresholds and smooth muscle tone were measured with a barostat before and after treatment in 18 patients (study I), and treatment changes in heart rate, blood pressure, skin conductance, finger temperature, and forehead electromyographic activity were assessed in 24 patients (study II). Somatization, anxiety, and depression were also measured. All central IBS symptoms improved substantially from treatment in both studies. Rectal pain thresholds, rectal smooth muscle tone, and autonomic functioning (except sweat gland reactivity) were unaffected by hypnosis treatment. However, somatization and psychological distress showed large decreases. In conclusion, hypnosis improves IBS symptoms through reductions in psychological distress and somatization. Improvements were unrelated to changes in the physiological parameters measured. 17 of 18 patients in study 1 and 21 of 24 patients in study 2 were judged substantially improved Improvement was well-maintained at 10-12 month follow up in study 2.

This study evaluated the rectal sensitivity changes in IBS patients who received hypnotherapy, like a previous study by the same group (see Houghton et al's study above, but using a slightly different methodology. Twenty-three IBS patients were tested before and after 12 weeks of hypnotherapy. Following the course of hypnotherapy, the mean pain sensory threshold increased in the hypersensitive subgroup and tended to decrease in the hyposensitive group, although the l. Reduction in gut pain sensitivity was associated with a reduction in abdominal pain. These results suggest that hypnotherapy may work at least partly by normalizing bowel perception in those patients who have abnormal gut sensitivity, while leaving normal sensation unchanged.

Cognitive change in patients undergoing hypnotherapy for irritable bowel syndrome.Cognitive changes were evaluated in 78 IBS patients who completed a 12-session hypnosis treatment course, using the recently developed Cognitive Scale for Functional Bowel Disorders. Hypnotherapy resulted in improvement of symptoms, quality of life, anxiety and depression. Unhelpful IBS-related cognitions improved significantly, with reduction in the total cognitive score and all component themes related to bowel function. Overall symptom reduction correlated with an improvement on the cognitive scale.
Gonsalkorale WM, Miller V, Afzal A, Whorwell PJ. Long term benefits of hypnotherapy for irritable bowel syndrome. Gut. 2003 Nov;52(11):1623-9. In this study, 204 IBS patients treated with a course of hypnotherapy completed questionnaires scoring symptoms, quality of life, anxiety, and depression before, immediately after, and up to six years following treatment. 71% of patients showed improvement in response to treatment initially, and of those, 81% were still improved years later, while most of the other 19% only reported slight worsening of symptoms. 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.

Department of Internal Medicine, Sahlgrenska University Hospital, Goteborg, Sweden. magnus.simren@medicine.gu.se OBJECTIVE: Postprandial symptoms in irritable bowel syndrome are common and relate to an exaggerated motor and sensory component of the gastro colonic response. We investigated whether this response can be affected by hypnotherapy. METHODS: We included 28 patients with irritable bowel syndrome refractory to other treatments. They were randomized to receive gut-directed hypnotherapy 1 hour per week for 12 weeks (N = 14) or were provided with supportive therapy (control group; N = 14). Before randomization and after 3 months, all patients underwent a colonic distension trial before and after a 1-hour duodenal lipid infusion. Colonic sensory thresholds and tonic and phasic motor activity were assessed. RESULTS: Before randomization, reduced thresholds after vs. before lipid infusion were seen in both groups for all studied sensations. At 3 months, the colonic sensitivity before duodenal lipids did not differ between groups. Controls reduced their thresholds after duodenal lipids for gas (22 +/- 1.7 mm Hg vs. 16 +/- 1.6 mm Hg, p <.01), discomfort (29 +/- 2.9 mm Hg vs. 22 +/- 2.6 mm Hg, p <.01), and pain (33 +/- 2.7 mm Hg vs. 26 +/- 3.3 mm Hg, p <.01), whereas the hypnotherapy group reduced their thresholds after lipids only for pain (35 +/- 4.0 mm Hg vs. 29 +/- 4.7 mm Hg, p <.01). The colonic balloon volumes and tone response at randomization were similar in both groups. At 3 months, baseline balloon volumes were lower in the hypnotherapy group than in controls (83 +/- 14 ml vs. 141 +/- 15 ml, p <.01). In the control group, reduced balloon volumes during lipid infusion were seen (141 +/- 15 ml vs. 111 +/- 19 ml, p <.05), but not after hypnotherapy (83 +/- 14 ml vs. 80 +/- 16 ml, p >.20). CONCLUSION: Hypnotherapy reduces the sensory and motor component of the gastro colonic response in patients with irritable bowel syndrome. These effects may be involved in the clinical efficacy of hypnotherapy in IBS.
Am J Clin Hypn. 2005 Jan;47(3):161-78. Hypnosis and irritable bowel syndrome: a review of efficacy and mechanism of action. Tan G, Hammond DC, Joseph G. Michael E. DeBakey VA Medical Center, Baylor College of Medicine, Houston, TX 77030, USA. tan.gabriel@med.va.gov Irritable bowel syndrome (IBS) is a functional gastrointestinal disorder characterized by abdominal pain, distension, and an altered bowel habit for which no cause can be found. Despite its prevalence, there remains a significant lack of efficacious medical treatments for IBS to date. In this paper we reviewed a total of 14 published studies (N=644) on the efficacy of hypnosis in treating IBS (8 with no control group and 6 with a control group). We concluded that hypnosis consistently produces significant results and improves the cardinal symptoms of IBS in the majority of patients, as well as positively affecting non-colonic symptoms. When evaluated according to the efficacy guidelines of the Clinical Psychology Division of American Psychological Association, the use of hypnosis with IBS qualifies for the highest level of acceptance as being both efficacious and specific. In reviewing the research on the mechanism of action as to how hypnosis works to reduce symptoms of IBS, some evidence was found to support both physiological and psychological mechanisms of action.

Int J Clin Exp Hypn. 2006 Jan;54(1):7-20. Hypnosis for irritable bowel syndrome: the empirical evidence of therapeutic effects. Whitehead WE. University of North Carolina at Chapel Hill, Chapel Hill, North Carolina 27599, USA. William_Whitehead@med.unc.edu Irritable bowel syndrome (IBS) is a complex and prevalent functional gastrointestinal disorder that is treated with limited effectiveness by standard medical care. Hypnosis treatment is, along with cognitive-behavioral therapy, the psychological therapy best researched as an intervention for IBS. Eleven studies, including 5 controlled studies, have assessed the therapeutic effects of hypnosis for IBS. Although this literature has significant limitations, such as small sample sizes and lack of parallel comparisons with other treatments, this body of research consistently shows hypnosis to have a substantial therapeutic impact on IBS, even for patients unresponsive to standard medical interventions. The median response rate to hypnosis treatment is 87%, bowel symptoms can generally be expected to improve by about half, psychological symptoms and life functioning improve after treatment, and therapeutic gains are well maintained for most patients for years after the end of treatment.
Gut. 2002 Nov;51(5):701-4. Visceral sensation and emotion: a study using hypnosis. Houghton LA, Calvert EL, Jackson NA, Cooper P, Whorwell PJ. Department of Medicine, University Hospital of South Manchester, Manchester M20 2LR, UK. lahoughton@man.ac.uk BACKGROUND AND OBJECTIVES: We have previously shown that hypnosis can be used to study the effect of different emotions on the motility of the gastrointestinal tract. These studies demonstrated that both anger and excitement increased colonic motility while happiness led to a reduction. The purpose of this study was to investigate the effect of hypnotically induced emotion on the visceral sensitivity of the gut. METHODS: Sensory responses to balloon distension of the rectum and compliance were assessed in 20 patients with irritable bowel syndrome (IBS) (aged 17-64 years; 17 female) diagnosed by the Rome I criteria. Patients were studied on four separate occasions in random order either awake (control) or in hypnosis, during which anger, happiness, or relaxation (neutral emotion) were induced. RESULTS: Hypnotic relaxation increased the distension volume required to induce discomfort (p=0.05) while anger reduced this threshold compared with relaxation (p<0.05), happiness (p<0.01), and awake conditions (p<0.001). Happiness did not further alter sensitivity from that observed during relaxation. There were no associated changes in rectal compliance or wall tension. CONCLUSIONS: Further to our previous observations on motility, this study shows that emotion can also affect an IBS patient's perception of rectal distension and demonstrates the critical role of the mind in modulating gastrointestinal physiology. These results emphasise how awareness of the emotional state of the patient is important when either measuring visceral sensitivity or treating IBS.
Gastroenterol Clin North Am. 1991 Jun;20(2):325-33. Treatment of the irritable bowel syndrome. Friedman G. Department of Medicine, Mt. Sinai School of Medicine, New York, New York. Individualization of treatment for patients with IBS is predicated on a thorough analysis of the patient's symptoms, consideration of the reasons for seeking health care, evaluation of symptom-precipitating factors, elimination of confounding features, and the absolute knowledge of the absence of organic illness. Collecting and codifying appropriate historical data allow the physician to educate the patient with respect to the origin of his symptoms, and to enlist the patient as a partner in his future health care. There is no single, universally accepted therapeutic agent available for the treatment of the IBS patient. As a result, treatment is directed at reducing the frequency and intensity of triggering factors as well as ameliorating the symptoms when they arise. Symptoms evoked by psychologic factors may be effectively reduced by psychotherapy or hypnotherapy. Situational anxiety may be treated for brief periods by using antianxiety agents such as diazepam, chlordiazepoxide, buspirone, or similar agents. Depressive reactions may be reduced with suitable doses of antidepressant agents such as amitriptyline. Smooth muscle hyperreactivity may be dulled with small amounts of selected anticholinergics, which are usually most effective in reducing meal-induced discomfort. Peppermint oil may be of additional benefit. Gas-related symptoms require elimination of contributory dietary factors, such as lactose-containing foods, sorbitol, or fructose, as well as certain oligosaccharides. Simethecone, charcoal, or beanase may be helpful. Functional constipation is best treated with graded doses of insoluble or soluble fiber. Diarrheal episodes may be reduced with either loperamide or diphenoxylate. Careful, continued follow-up assessment of therapeutic endeavors, a sincere interest in the patient's concerns, and surveillance for intercurrent organic illness are the cornerstones of complete ongoing care.
Curr Treat Options Gastroenterol. 1999 Feb;2(1):13-19 Irritable Bowel Syndrome. Wald A. University of Pittsburgh Medical Center, Pittsburgh University Hospital, Mezzanine Level, C-Wing, 200 Lothrop Street, Pittsburgh, PA 15213-2582. I believe there are four essential elements in the management of patients with irritable bowel syndrome (IBS): to establish a good physician-patient relationship; to educate patients about their condition; to emphasize the excellent prognosis and benign nature of the illness; and to employ therapeutic interventions centering on dietary modifications, pharmacotherapy, and behavioral strategies tailored to the individual. Initially, I establish the diagnosis, exclude organic causes, educate patients about the disease, establish realistic expectations and consistent limits, and involve patients in disease management. I find it critical to determine why the patient is seeking assistance (eg, cancer phobia, disability, interpersonal distress, or exacerbation of symptoms). Most patients can be treated by their primary care physician. However, specialty consultations may be needed to reinforce management strategies, perform additional diagnostic tests, or institute specialized treatment. Psychological co-morbidities do not cause symptoms but do affect how patients respond to them and influence health care-seeking behavior. I find that these issues are best explored over a series of visits when the physician-patient relationship has been established. It can be helpful to have patients fill out a self-administered test to identify psychological co-morbidities. I often use these tests as a basis for extended inquiries into this area, resulting in the initiation of appropriate therapies. I encourage patients to keep a 2-week diary of food intake and gastrointestinal symptoms. In this way, patients become actively involved in management of their disease, and I may be able to obtain information from the diary that will be valuable in making treatment decisions. I do not believe that diagnostic studies for food intolerances are cost-effective or particularly helpful; however, exclusion diets may be beneficial. I introduce fiber supplements gradually and monitor them for tolerance and palatability. Synthetic fiber is often better-tolerated than natural fiber, but must be individualized. In my experience, excessive fiber supplementation often is counterproductive, as abdominal cramps and bloating may worsen. Antidiarrheal agents are very effective when used correctly, preferably in divided doses. I use them in patients in anticipation of diarrhea and especially in those who fear symptoms when engaged in activities outside the home. I encourage patients to make decisions as to when and how much to use. However, almost always, a morning dose before breakfast is used (loperamide, 2 to 6 mg) and, perhaps again later in the day when symptoms of diarrhea are prominent. I prefer antispasmodics to be used intermittently in response to periods of increased abdominal pain, cramps, and urgency. For patients with daily symptoms, especially after meals, agents such as dicyclomine before meals are useful. For patients with infrequent but severe episodes of unpredictable pain, sublingual hyoscyamine often produces rapid relief and instills confidence. In general, I recommend that oral antispasmodics be used for a limited period of time rather than indefinitely, and generally for periods of time when symptoms are prominent. For chronic visceral pain syndromes, I recommend small doses of tricyclic antidepressants. These agents are especially effective in diarrhea-predominant patients with disturbed sleep patterns but may be unacceptable to patients with constipation. I educate patients that side effects occur early and benefits may not be apparent for 3 to 4 weeks. I consider using SSRIs in low doses in patients with constipation-predominant IBS; cisapride, 10 to 20 mg three times per day, also may be beneficial. When taken with drugs that inhibit cytochrome P450, cisapride has been associated with serious cardiac arrhythmias caused by QT prolongation, including ventricular arrhythmias and torsades de pointes. These drugs include the azole fungicides; erythromycin, clarithromycin, and troleandomycin; some antidepressants; HIV protease inhibitors; and others. In patients with IBS with mild to moderate co-morbid depression, I have found that the use of SSRIs such as paroxetine, fluoxetine, or sertraline may be beneficial. It is important to tell patients that anxiety and disturbed sleep may occur during the first 10 days and benefits may not occur for 3 to 4 weeks. I prescribe a small amount of a short-acting benzodiazepine such as alprazolam, 0.5 mg two times per day, to control these symptoms. For generalized anxiety without depression, buspirone or clonazepam may be useful. I have found that patients who also have associated panic disorder may benefit from a benzodiazepine, tricyclic antidepressant, or an SSRI. However, these patients are best managed in conjunction with a psychiatrist or psychologist. I consider the use of alternative therapies in patients who fail to respond to conventional measures and who are receptive to alternative strategies. These include general relaxation techniques such as biofeedback and hypnosis therapies.
J Clin Nurs. 2006 Jun;15(6):678-84 Effect of nurse-led gut-directed hypnotherapy upon health-related quality of life in patients with irritable bowel syndrome. Smith GD. School of Health in Social Science, University of Edinburgh, Old Medical School, Edinburgh, UK. graeme.smith@ed.ac.uk AIMS AND OBJECTIVES: This study quantified health-related quality of life in a group of irritable bowel syndrome patients and measures changes following a treatment programme of nurse-led gut-directed hypnotherapy. BACKGROUND: It is well recognized that health-related quality of life can be severely impaired in patients suffering form the irritable bowel syndrome. Current conventional treatment for irritable bowel syndrome is often unsatisfactory. In contrast it has been shown that gut-directed hypnotherapy is an effective treatment of irritable bowel syndrome with up to three-quarters of patients reporting symptomatic improvement. DESIGN/METHOD: Seventy-five patients (55 females/20 males, median age 37.1 years, age range 18-64) comprised the study group. Physical symptoms of irritable bowel syndrome were recorded using seven-day diary cards. On presentation the predominant symptoms were abdominal pain (61%), altered bowel habit (32.5%), and abdominal distension/bloating (6.5%) in the patient group. An irritable bowel syndrome quality of life questionnaire was used to define health-related quality of life. Psychological well-being was measured using the Hospital Anxiety and Depression Scale. Data analysis was carried out using MINITAB, Release 12 for Windows. RESULTS: Physical symptoms statistically improved after hypnotherapy. There were also significant statistical improvements (P < 0.001) in six of the eight health-related quality of life domains measured (emotional, mental health, sleep, physical function, energy and social role). These improvements were most marked in female patients who reported abdominal pain as their predominant physical symptom. Anxiety and depression improved following treatment. CONCLUSION: Gut-directed hypnotherapy has a very positive impact on health-related quality of life with improvements in psychological well-being and physical symptoms. It appears most effective in patients with abdominal pain and distension. Relevance to clinical practice. This study demonstrates that by integrating complementary therapies into conventional care that gastrointestinal nurses have a potential role in the management of irritable bowel syndrome.
Gastroenterology. 2007 Nov;133(5):1430-6. Epub 2007 Sep 2 Hypnotherapy for children with functional abdominal pain or irritable bowel syndrome: a randomized controlled trial. Vlieger AM, Menko-Frankenhuis C, Wolfkamp SC, Tromp E, Benninga MA. Department of Pediatrics, St. Antonius Hospital, Nieuwegein, The Netherlands. a.vlieger@antonius.net BACKGROUND & AIMS: Functional abdominal pain (FAP) and irritable bowel syndrome (IBS) are highly prevalent in childhood. A substantial proportion of patients continues to experience long-lasting symptoms. Gut-directed hypnotherapy (HT) has been shown to be highly effective in the treatment of adult IBS patients. We undertook a randomized controlled trial and compared clinical effectiveness of HT with standard medical therapy (SMT) in children with FAP or IBS. METHODS: Fifty-three pediatric patients, age 8-18 years, with FAP (n = 31) or IBS (n = 22), were randomized to either HT or SMT. Hypnotherapy consisted of 6 sessions over a 3-month period. Patients in the SMT group received standard medical care and 6 sessions of supportive therapy. Pain intensity, pain frequency, and associated symptoms were scored in weekly standardized abdominal pain diaries at baseline, during therapy, and 6 and 12 months after therapy. RESULTS: Pain scores decreased significantly in both groups: from baseline to 1 year follow-up, pain intensity scores decreased in the HT group from 13.5 to 1.3 and in the SMT group from 14.1 to 8.0. Pain frequency scores decreased from 13.5 to 1.1 in the HT group and from 14.4 to 9.3 in the SMT group. Hypnotherapy was highly superior, with a significantly greater reduction in pain scores compared with SMT (P < .001). At 1 year follow-up, successful treatment was accomplished in 85% of the HT group and 25% of the SMT group (P < .001). CONCLUSIONS: Gut-directed HT is highly effective in the treatment of children with longstanding FAP or IBS. PMID: 17919634 [PubMed - indexed for MEDLINE]
