European Consensus on Functional Bloating and Abdominal Distension-An ESNM/UEG Recommendations for Clinical Management
Abstract
INTRODUCTION: Abdominal distension is an objective visible sign of increased abdominal girth. Bloating is a feeling of abdominal fullness and discomfort. Bloating may be associated or not with abdominal distension. Bloating and abdominal distension are among the most commonly reported gastrointestinal symptoms and may be associated with both organic and functional disorders. Nevertheless, specific consensus and recommendations on diagnosis, underlying mechanisms, assessment and management of functional bloating and abdominal distension are still lacking. The aim of this European consensus, then, is to provide expert opinions and recommendations on the epidemiology, diagnosis, pathophysiology and treatment of functional bloating and abdominal distension.
METHODS: A multidisciplinary team of experts in the field, including European specialists and national societies, participated in the development of this consensus. Relevant questions were formulated and addressed through a literature review and statements were developed and voted using a Delphi process.
RESULTS: Functional bloating and abdominal distension are common and frequently overlap with other disorders of gut-brain interaction. Diagnosis is made according to the Rome IV criteria after the exclusion of organic disease, based on the physical examination and assessment of the patient's medical history and alarming signs. In the absence of alarming signs or any relevant finding, clinical laboratory, imaging or endoscopic…
