Treating disorders of brain–gut interaction with multidisciplinary integrated care. Moving towards a new standard of care

Abstract

Disorders of brain–gut interaction (DGBI) are highly prevalent in our community with a negative burden on the quality of life and function. Symptoms are frequently food‐induced, and psychological disorders are commonly co‐morbid and contribute greatly to symptom severity and healthcare utilization, which can complicate management. Pathophysiological contributors to the development and maintenance of DGBI are best appreciated within the biopsychosocial model of illness. Established treatments include medical therapies targeting gastrointestinal physiology, luminal microbiota or visceral sensitivity, dietary treatments including dietary optimization and specific therapeutic diets such as a low‐FODMAP diet, and psychological interventions. The traditional “medical model” of care, driven predominantly by doctors, poorly serves sufferers of DBGI, with research indicating that a multidisciplinary, integrated‐care approach produces better outcomes. This narrative review explores the current evidence for multidisciplinary care and provides the best practice recommendations for physicians and healthcare systems managing such patients.
