What is the remaining percentage of alcohol absorbed through the upper intestine after being consumed on an empty stomach?

The correct answer is that 80% of alcohol is absorbed through the upper intestine after being consumed on an empty stomach. When a person drinks alcohol without any food in their stomach, the body can absorb the alcohol more rapidly. The upper intestine, specifically the duodenum, plays a significant role in this absorption process.

Alcohol is quickly absorbed into the bloodstream, particularly from the small intestine, where up to 80% can enter circulation. This rapid absorption can lead to heightened effects of alcohol in the body, contributing to a more pronounced state of intoxication. When there is no food to slow down the absorption rate, the likelihood of reaching high blood alcohol concentration levels increases.

Understanding this concept is crucial for awareness of the risks associated with drinking alcohol on an empty stomach, which leads to faster intoxication and can impair judgment and coordination more significantly than consuming alcohol with food.
