Synopsis

Source of validity: Scientific
Rating (out of 5): 2

Bicarbonate (mixed), commonly in the form of sodium bicarbonate or similar compounds, is used as an antacid to neutralize stomach acid. The use of bicarbonate for belching (eructation) is scientifically grounded, although the evidence is modest. Belching is often caused by swallowed air or by the release of gas produced by neutralization reactions in the stomach. When bicarbonate reacts with gastric hydrochloric acid, it produces carbon dioxide gas, which can increase the urge to belch as the gas is expelled from the stomach.

Clinical guidelines and pharmacological texts list sodium bicarbonate as a rapid-acting antacid that provides symptomatic relief of dyspepsia, which can sometimes include belching. However, its use specifically for belching is less well-studied compared to its use for heartburn or acid indigestion. Some evidence suggests that while bicarbonate may relieve acid-related discomfort, it can paradoxically increase belching due to the carbon dioxide produced during neutralization. This effect is well-documented in pharmacology literature, but there are few high-quality clinical trials specifically investigating bicarbonate for treating belching alone.

Therefore, while there is a plausible scientific mechanism and some supporting evidence for the use of mixed bicarbonate in relieving symptoms associated with belching, the quality and directness of the evidence is limited. Its use is more a consequence of its general antacid action, rather than a targeted therapy for belching per se.
