- Abstract
Background: Belching disorders and rumination syndrome (RS) are disorders of gut-brain interaction (DGBIs) in Rome IV. Belching disorders are composed of excessive gastric belching (GB) and supragastric belching (SGB). Excessive GB is related to physiological phenomenon whereas excessive SGB and RS are behavioral disorders., Summary: A recent large internet survey found that prevalence of belching disorders and RS were 1% and 2.8%, respectively. It has been recognized that not a few patients with two behavioral disorders, excessive SGB and RS, could be misdiagnosed as proton pump inhibitors (PPI)-refractory gastroesophageal reflux disease (GERD). In patients with reflux symptoms, distinguishing these conditions is essential because they need psychological treatment (i.e., cognitive behavioral therapy (CBT) rather than acid suppressants. Clinicians should take a medical history meticulously first to identify possible excessive SGB and/or RS. High-resolution impedance manometry and/or 24-h impedance-pH monitoring can offer an objective diagnosis of the disorders. Several therapeutic options are available for excessive SGB and RS. The first-line therapy should be CBT using diaphragmatic breathing that can stop the behaviors involving complex muscle contraction (e.g., abdominal straining) to generate SGB or rumination. Overlap with eating disorders and/or other DGBIs such as functional dyspepsia can make management of the behavioral disorders challenging since such coexisting conditions often require additional treatments., Key Messages: Excessive SGB and RS are not unusual conditions. It is important to raise awareness of the behavioral disorders for appropriate management., (© 2023 S. Karger AG, Basel.)
