Hypnotherapy seems to be an effective long term treatment for irritable
bowel syndrome, research finds.
IBS is a very common disorder affecting up to 15%
of the population at any one time, but is difficult to treat.
Researchers from Withington Hospital, Manchester, found hypnotherapy
helped 71% of patients - and its effect lasted up to five years
after treatment.
The research, based on 200 patients, is published
in the journal Gut.
The patients were given one hour sessions of hypnotherapy
for up to 12 weeks.
They were asked to assess their symptoms, quality
of life and levels of anxiety and depression before and after treatment
- and for up to six years after completing the course.
The majority of patients found that hypnotherapy
reduced the severity of their IBS symptoms, and continued to do
so for years.
Even those who said the effect began to wear off
with time, found that the deterioration was slight.
Cost effective
Hypnotherapy also seemed significantly to reduce levels of anxiety
and depression - however, the effect here did begin to tail off
slightly over time.
But patients also said they took fewer drugs and
did not need to see their doctors as often after they had had a
course of hypnotherapy.
The researchers say the sustained improvements in
most of the patients cannot be attributed to other treatments as
fewer than one in 10 patients attempted alternatives after completing
their hypnotherapy sessions.
Previous research has shown hypnotherapy to have
a beneficial effect on IBS in the short term - but not over a longer
period.
Critics say hypnotherapy is an expensive treatment.
But the researchers argue that the cost would be more than offset
by a reduction in demand for prescription drugs.
Lead researcher Dr Wendy Gonsalkorale told BBC News
Online: "While other studies have shown that symptoms have
improved by the end of the course of treatment, the real significance
is our finding that these effects are sustained after treatment
sessions have finished, rather than patients just reverting back
to their original state.
"We firmly believe that hypnotherapy should
be available as a standard treatment for all patients with IBS."
Effect unclear
Dr Gonsalkorale said it was unclear what caused IBS, and why hypnotherapy
should help.
However, she said the condition was possibly linked
to problems with muscle movement, or to increased sensitivity of
the gut lining.
She said hypnotherapy may help the patient to gain
better control over the way their gut works by influencing the release
of hormones, or the nerve links between the gut and the brain.
It may also alter the way that the brain responds
to incoming pain messages.
"For some patients, psychological factors and
stresses may play a role in triggering or at least exacerbating
symptoms.
"Whether or not they are the primary cause
is still very debatable. Hypnosis can be used as a form of relaxation,
to reduce stress.
"But it is not the whole story by any means.
We know also that the therapy alters the way patients think about
their symptoms."
Dr Mark Cottrill, a trustee of the IBS Network and
a GP in Wigan, told BBC News Online his practice had employed the
services of a hypnotherapist to treat IBS patients for a short time.
"She proved extremely popular and within months
she had a three to four month waiting list," he said.
"But we had to end the sessions because we had no funding for
them. It can cost £600 per patient and the money has to be
found upfront."
