As an individual ages, how is their BAC typically affected?

1. It decreases

2. It remains constant

3. It increases

4. It fluctuates unpredictably

The correct answer is: It increases

As individuals age, several physiological changes occur that can affect how alcohol is processed in the body, leading to an increase in Blood Alcohol Concentration (BAC). One primary factor is the decrease in total body water and muscle mass, which means that alcohol is distributed in a smaller volume. Consequently, with the same amount of alcohol consumed, older adults may experience a higher BAC compared to younger individuals. Additionally, aging can affect the liver's ability to metabolize alcohol efficiently. As liver function diminishes over time, the breakdown of alcohol slows, allowing it to remain in the bloodstream longer. Hormonal changes, as well as age-related changes in enzyme activity that contribute to alcohol metabolism, can also play a role in this increased BAC. Thus, the combination of these physiological factors typically results in a higher BAC for older individuals after consuming the same quantity of alcohol as younger people. This understanding is crucial for safe alcohol service practices, especially in settings serving older patrons.
