Brain-gut interactions in IBS. Integration of peripheral and central pathophysiology

Irritable bowel syndrome (IBS) is a chronic disorder characterized by abdominal pain and alterations in bowel habits (diarrhea, constipation, or both in an alternating pattern). IBS is also associated with mental and physical comorbidity such as anxiety, depression, fatigue and other chronic pain syndromes. Despite advances in modern medicine, IBS remains a persistent, disabling, and costly problem.

IBS is a disorder of dysregulated brain–gut homeostasis involving peripheral and central mechanisms. An increasing body of evidence strongly supports both the role of peripheral factors such as disturbed microbiota composition, mucosal barrier or gut immune function but also altered brain function in IBS pathophysiology.

Together with national and international collaborators and a local team consisting of gastroenterologists, psychologists, physicists and biologist we aim to provide new data on microbiota- immune-CNS interactions in IBS pathophysiology. The overall aim of ours studies are linking together central and peripheral components of the brain-gut-microbiota axis.
