Introduction:
Excessive bothersome belching is clinically problematic and the Rome IV classification categorizes belching disorders as gastroduodenal disorders.
Methods:
A total of 10,000 Japanese adults participated in this web-based survey. We aimed to examine the prevalence of belching disorders and their characteristics.
Results:
Belching disorders were found in 151 (1.5%) adults. The presence of reflux esophagitis, thyroid diseases, gastroesophageal reflux disease, functional dyspepsia, full eaters, or a small or large number of mastication was significantly associated with an increased odds ratio of belching disorders.
Discussion:
A detailed epidemiology of belching disorders in adults was clarified.
