Hypnotherapy works in conjunction with, and does not interfere with other clinical treatment of IBS. Whether used on its own or complimentary to clinical treatment, studies strongly suggest hypnotherapy is a highly effective treatment for IBS as reflected by Professor Peter Whorwell, Professor of Medicine and Gastroenterology, The University of Manchester United Kingdom
"IBS is ideal for treatment with hypnosis, as there is no structural damage to the body," explained Professor Whorwell. "During the hypnotherapy, sufferers learn how to influence and gain control of their gut functions, and then seem to be able to change the way the brain modulates their gut activity."

Hypnotherapy can normalise abnormal gut activity, sensitivity and lessen pain. Suggestions or imagery specifically directed at reducing the intestinal pain and activity are highly effective. Hypnosis acts on the part of the brain that alters mind-body interactions by controlling reactions to stress and regulating digestion, the immune system, mood and emotions. Relaxation techniques alone show positive results with IBS patients as they learn how to manage their stress levels and increase relaxation, which under any circumstance is a positive outcome for anyone’s health.
