IBS is often linked to stress, but the vast majority of treatments focus only on restrictive diets. By contrast, this book addresses the emotional component of the disorder through new research based on Cognitive Behavioural Therapy. It actually encourages people to change the way they think about the ailment and stop avoiding situations they fear might exacerbate their symptoms. Tested in a unique randomised controlled trial by the author - who is a clinical psychologist and scientist - this programme, based on a solid scientific foundation, offers new hope for IBS sufferers.
