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.

[PMID: 38337655 PMCID: PMC10857121 DOI: 10.3390/nu16030370] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/08/2024] [Revised: 01/23/2024] [Accepted: 01/25/2024] [Indexed: 02/12/2024] Open
Abstract
The low FODMAP (fermentable oligosaccharide, disaccharide, monosaccharide, and polyol) diet is a beneficial therapeutic approach for patients with irritable bowel syndrome (IBS). However, how the low FODMAP diet works is still not completely understood. These mechanisms encompass not only traditionally known factors such as luminal distension induced by gas and water but also recent evidence on the role of FOMAPs in the modulation of visceral hypersensitivity, increases in intestinal permeability, the induction of microbiota changes, and the production of short-chain fatty acids (SCFAs), as well as metabolomics and alterations in motility. Although most of the supporting evidence is of low quality, recent trials have confirmed its effectiveness, even though the majority of the evidence pertains only to the restriction phase and its effectiveness in relieving abdominal bloating and pain. This review examines potential pathophysiological mechanisms and provides an overview of the existing evidence on the effectiveness of the low FODMAP diet across various IBS subtypes. Key considerations for its use include the challenges and disadvantages associated with its practical implementation, including the need for professional guidance, variations in individual responses, concerns related to microbiota, nutritional deficiencies, the development of constipation, the necessity of excluding an eating disorder before commencing the diet, and the scarcity of long-term data. Despite its recognized efficacy in symptom management, acknowledging these limitations becomes imperative for a nuanced comprehension of the role of a low FODMAP diet in managing IBS. By investigating its potential mechanisms and evidence across IBS subtypes and addressing emerging modulations alongside limitations, this review aims to serve as a valuable resource for healthcare practitioners, researchers, and patients navigating the intricate landscape of IBS.
