What can influence how quickly alcohol leaves the stomach?

The presence of food in the stomach significantly influences the rate at which alcohol is absorbed into the bloodstream and subsequently leaves the stomach. When food is consumed alongside alcohol, it can slow down gastric emptying, meaning the alcohol remains in the stomach for a longer period. Consequently, this results in a more gradual absorption of alcohol into the bloodstream, leading to a slower increase in blood alcohol concentration (BAC).

On the other hand, when alcohol is consumed on an empty stomach, it is absorbed more rapidly, leading to a quicker rise in BAC, which can intensify the effects of alcohol consumption. This physiological process highlights the critical role that food plays in moderating the effects of alcohol by acting as a buffer, allowing for a more controlled absorption rate.
