Examining the effects of alcohol consumption.
Young women generally reach higher blood-alcohol concentrations than young men after consuming the same amount of alcohol due to three primary physiological differences:1
- Gastric Enzyme Levels: Women typically have lower levels of the enzyme alcohol dehydrogenase (ADH) in their gastric secretions. Because this enzyme breaks down a portion of alcohol in the stomach before it reaches the bloodstream, women absorb a higher percentage of the alcohol they consume.1
- Body Composition: Alcohol is diffused throughout the body in proportion to water content. Because women generally have a different ratio of body water to body fat compared to men, the alcohol is less diluted in a woman's system.1
- Body Size: Differences in overall body size also contribute to the variance in how alcohol is distributed and concentrated in the blood.1
These combined factors can result in blood-alcohol levels up to 50 percent higher in women than in men after consuming an identical amount of alcoholic beverage.1
