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 conven-tional treatment for irritable bowel syndrome is often unsatisfactory. In contrast ithas been shown that gut-directed hypnotherapy is an effective treatment of irritablebowel syndrome with up to three-quarters of patients reporting symptomaticimprovement.
Design/method. Seventy-five patients (55 females/20 males, median age 37Æ1 years,age range 18–64) comprised the study group. Physical symptoms of irritable bowelsyndrome were recorded using seven-day diary cards. On presentation the pre-dominant symptoms were abdominal pain (61%), altered bowel habit (32Æ5%), andabdominal distension/bloating (6Æ5%) in the patient group. An irritable bowelsyndrome quality of life questionnaire was used to define health-related quality oflife. Psychological well-being was measured using the Hospital Anxiety andDepression Scale. Data analysis was carried out using MINITAB, Release 12 forWindows.
Results. Physical symptoms statistically improved after hypnotherapy. There werealso significant statistical improvements (P < 0Æ001) in six of the eight health-related quality of life domains measured (emotional, mental health, sleep, physicalfunction, energy and social role). These improvements were most marked in femalepatients 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-relatedquality of life with improvements in psychological well-being and physical symp-toms. It appears most effective in patients with abdominal pain and distension.
Relevance to clinical practice. This study demonstrates that by integrating com-plementary therapies into conventional care that gastrointestinal nurses have apotential role in the management of irritable bowel syndrome.

Therefore IBS can have a significant impact on health- Consequently, treatment options are often focused on the related quality of life (HRQoL) and several studies have relief of specific symptoms. Several proposed mechanisms to clearly shown that HRQoL is adversely affected by IBS (Houghton et al. 1996, Luscombe 2000, El-Serag et al. 2002).
This may be because of physical symptoms, psychological stress (Talley et al. 1996), sexual dysfunction (Guthrie et al.

Gut function at the end-organ level is controlled and it is now recognized as an important outcome measure in by a very intricate nerve supply, the enteric nervous system.

Diagnosis must Little is known of the pathophysiology of IBS and, as a be based on the presence of key symptoms and IBS is consequence, medical treatment is often ineffective (Akehurst diagnosed positively on the basis of symptom criteria and the & Kaltenthaler 2001). In recent years there has been growing exclusion of organic gastrointestinal (GI) illnesses (Camilleri interest in the use of complementary therapies in gastro- & Choi 1997). Symptom-based diagnostic criteria have been used to define IBS for some time, initially the manning criteriain the 1970s followed by Rome I criteria in 1992 (Thompson et al. 1989). The most recent criteria are the Rome IIguidelines summarized in Fig. 1 (Thompson et al. 1999).

Thus, anxiety may be a cause or a consequence of the disease. Pharmaceutical agents currently recommended by the British Society of Gastroenterology are summarized in Fig. 2 Phrases, such as, ‘I can’t stomach that’ or ‘gut feeling’ highlight the very significant role the gut plays as a vehicle ofsomatic expression. An understanding of role of psychosocialfactors is therefore required to optimize the nursing care of Non-pharmacological interventions: nursing role Previous research has suggested that a majority of nurses Gut-directed hypnotherapy has been shown to improve hold negative attitudes towards IBS sufferers. IBS patients physical symptoms in IBS patients. Whorwell et al.

However, more recently it has been clearly indicated treated by hypnotherapy. This group subsequently showed that these negative perceptions have changed dramatically that hypnotherapy had a positive effect upon a range of other and that present-day nurses fully understand the need for features of this disease and that treatment reduced the rate of specialist advice, support and reassurance for IBS patients absenteeism from work (Houghton et al. 1996).

An understanding of the role of nurses in the recently, gut-directed hypnotherapy has been demonstrated assessment and management of patients with IBS, with to be an effective long-term treatment strategy for IBS specific regard to education, reassurance and psychological well-being, is now well established (Smith 2003).
