How do drinks with carbonation affect alcohol absorption in the bloodstream?

Drinks with carbonation can speed up the rate of alcohol absorption in the bloodstream. The carbonation in beverages, such as sparkling wines or certain cocktails, increases the pressure in the stomach, leading to a faster release of carbon dioxide (CO2). This can result in the alcohol being absorbed more rapidly through the stomach lining into the bloodstream. Moreover, the bubbles create a change in gastric emptying, often leading to a quicker transition of the liquid into the small intestine, where alcohol absorption is more efficient.

This phenomenon can result in individuals feeling the effects of alcohol sooner than they might with non-carbonated drinks, contributing to a faster onset of intoxication. Understanding this effect is important for responsible drinking, as it can influence how quickly a person feels the impact of the alcohol consumed.
