Core Tip
Core tip: This review deals with the role of negative affects in pathophysiology and clinical expression of irritable bowel syndrome (IBS). Depression, anxiety, and anger play a key role in dysregulation of the brain-gut axis, contributing to the majority of pathophysiological and symptomatic correlates of IBS. Research efforts to integrate different knowledge provide further insight into the pathways linking negative psychological states to health and disease, leading to identification of individual vulnerability and susceptibility factors, including subsyndromal conditions, which should be addressed to promote better health in the population and more effective and efficient prevention and treatment of IBS.
