Belching: Pathogenesis, Clinical Characteristics, and Treatment Strategies

Purpose: Belching is a common condition that frequently overlaps with other functional gastrointestinal disorders. While not associated with any increase in mortality, it is associated with impaired health-related quality of life. Management is challenging, as there are no pharmacologic therapies specifically targeted towards this disorder. This review covers pathogenesis, prevalence, and treatments for this condition, with specific emphasis on the evolving role of behavioral treatments in management. Key Findings: The diagnosis of gastric and supragastric belching can usually be made clinically, without the need for invasive testing. If necessary, multichannel intraluminal impedance and pH testing can provide a more definitive diagnosis and can also be used to estimate the frequency of gastric and supragastric belching episodes, which each have a distinct appearance on impedance tracing. Belching disorders are commonly associated with gastroesophageal reflux disease and functional disorders of the gastrointestinal tract. Supragastric belching is also associated with behavioral disorders like anxiety and obsessive-compulsive disorder. Speech therapy, cognitive-behavioral therapy, and diaphragmatic breathing are all interventions that have recently shown promise in the management of this challenging disorder.
