Burping in Gastritis: Mechanisms and Prevalence

Mechanisms of Burping

Gastric belching is physiologically normal and involves spontaneous transient relaxation of the lower esophageal sphincter followed by air transport from the stomach through the esophagus, with subsequent relaxation of the upper esophageal sphincter allowing air to be expelled orally, as reported by the American Gastroenterological Association 1, 2
In patients with gastritis, particularly when associated with GERD, gastric belching has been reported in up to 50% of cases, according to the American Gastroenterological Association 1
Structural causes that may contribute to belching in gastritis patients include hiatal hernias and paraesophageal hernias, as noted by the American Gastroenterological Association 3
Gastric belching is different from supragastric belching, which is more commonly associated with anxiety and involves air being drawn into the esophagus and immediately expelled before reaching the stomach, as distinguished by the American Gastroenterological Association 4

High-resolution esophageal manometry combined with impedance monitoring can differentiate between gastric and supragastric belching in patients with persistent symptoms, as recommended by the American Gastroenterological Association 2
Behavioral strategies, including diaphragmatic breathing, can be effective for managing belching symptoms, particularly for supragastric belching, as suggested by the American Gastroenterological Association 6
When belching is excessive and significantly impacts quality of life, it should be evaluated as a potential disorder of gut-brain interaction rather than simply a symptom of gastritis, according to the American Gastroenterological Association 3
