Belching, also known as eructation, is the release of air from the stomach through the mouth, often caused by swallowed air or digestive processes. Water is sometimes recommended as a remedy for belching, and there is some scientific rationale for its use, though the evidence is limited and not robust. Drinking water can help by clearing excess air from the esophagus and aiding in the movement of food and gas through the digestive tract, which can decrease the frequency of belching. Additionally, sipping water may help wash down any irritants in the throat or esophagus that could be contributing to discomfort and reflexive belching. However, the effect of water can vary depending on the underlying cause. For individuals who experience belching due to rapid eating or aerophagia (swallowing air), drinking water slowly may help reduce the ingestion of air. In contrast, carbonated water or beverages can worsen belching by introducing more gas. A few small clinical studies and reviews suggest that lifestyle modifications—including drinking water instead of carbonated drinks—can be beneficial for reducing belching associated with gastroesophageal reflux disease (GERD) and functional dyspepsia. Overall, while water is not a specific treatment for belching, its use is supported by a modest scientific rationale and is included in some medical advice as part of lifestyle changes to reduce gastrointestinal symptoms. The strength of direct clinical evidence is low (rated 2 out of 5), but water is safe, accessible, and may provide mild benefit for some individuals.
