[Irritable bowel syndrome: comorbid psychiatric disorders and psychological treatment options]

Irritable bowel syndrome is a chronic functional gastrointestinal disorder with a prevalence of 7-21%. It has a negative impact on health-related quality of life and work productivity and it is associated with increased psychological distress and mental comorbidity, like major depression disorder and generalised anxiety disorder. Due to biopsychosocial factors and the brain-gut axis playing a key role in the aetiology of the disease, the use of psychological treatments has great importance in the therapy of irritable bowel syndrome. These interventions focus on central mechanisms, like visceral sensitivity, pain amplification, hypervigilance and gastrointestinal symptom-specific anxiety. They significantly reduce damaging illness-related cognitions, the use of maladaptive coping strategies, catastrophic appraisals of bodily sensations and chronic muscle tension. The utilization of these treatments is associated with clinically significant symptom improvement and positive mental health outcomes. This review study focuses on the psychiatric comorbidity of irritable bowel syndrome and the use of evidence-based psychological therapies in the treatment of the disease. Using ScienceDirect and PubMed databases, almost 60 studies have been selected. A high number of studies investigate the efficacy of cognitive behaviour therapy and hypnotherapy with meta-analyses included. There is also growing evidence on the beneficial impacts of mindfulness-based stress reduction. Future research will need to concentrate on studying the utility of mind-body therapies such as relaxation techniques in the treatment of irritable bowel syndrome with meta-analyses on the effects of mindfulness-based interventions.
