Background:
Functional bowel disorders, including irritable bowel syndrome
(IBS) are heterogeneous in terms of pathogenesis and presentation.
Consequently, the therapies prescribed for the management
of symptoms are equally diverse. However, long term and
patients' perceptions of the efficacy of these treatments
are often not well understood.
Objective:
To investigate patients' perspectives on efficacy of management
practices used for functional bowel disorders, including
irritable bowel syndrome (IBS).
Methods:
A questionnaire was posted to all patients with IBS or functional
bowel disease who attended the Allergy Unit, and/or a Private
Gastroenterology Practice at Royal Prince Alfred Hospital,
between January 1998 and December 1999. Questions focused
on medical and alternative therapies trialled by the patient,
and the perceived short and long-term efficacy of the therapies.
Responses were analysed using Excel and SPSS to perform
ANOVAs and t-tests.
Results:
Data from 97 patients was analysed. Perceptions of treatment
efficacy were very varied. Patients in this study perceived
dietary manipulation, mostly in the form of elimination
of specific chemicals from the diet, was most effective
in reducing symptoms. Medication was also important. Relaxation
techniques, although not perceived to be of greatest importance,
were a common second choice of therapy. High fibre diets
did not rate highly, although data about high fibre diets
was incomplete.
Conclusions:
The perceived efficacy of treatments is personal, and probably
reflects the specific mechanisms underlying the symptoms
in an individual. Most people have trialled a number of therapies
(av. 9.4, range 1-37), before finding one or a combination
which works to bring some relief from their symptoms. The
large percentage of patients from both practices rating
dietary manipulation as most important for symptom relief
suggests food intolerance should be investigated more thoroughly
for a substantial subgroup of this population.
