What effect do carbonated drinks have on the absorption rate of alcohol?

Carbonated drinks can speed up the absorption of alcohol due to several physiological factors. When alcohol is consumed with carbonation, the bubbles in the drink introduce carbonation into the stomach and create carbonation-induced pressure. This pressure can lead to a more rapid passage of alcohol from the stomach into the small intestine, where absorption occurs more efficiently.

Additionally, carbonation may irritate the stomach lining, leading to a quicker release of alcohol into the bloodstream. Therefore, when alcohol is consumed in carbonated beverages, the combination of pressure and increased gastric emptying time contributes to a faster absorption rate compared to non-carbonated drinks.

Understanding this mechanism highlights the importance of the beverage type when consuming alcohol, as it can significantly influence blood alcohol concentration and the overall experience of intoxication.
