What condition often accompanies alcohol intoxication related to dehydration?

A hangover is a condition that frequently accompanies alcohol intoxication and is primarily characterized by a range of symptoms, including headaches, nausea, fatigue, and dehydration. When alcohol is consumed, it acts as a diuretic, leading to increased urination and subsequent fluid loss. This fluid loss can contribute to dehydration, one of the core contributors to hangover symptoms.

As the body metabolizes alcohol, it also produces acetaldehyde, a toxic byproduct that can lead to inflammation and exacerbate feelings of discomfort in the days following consumption, thus contributing to the hangover experience. Therefore, recognizing that a hangover involves symptoms directly tied to both the intake of alcohol and the subsequent dehydration helps underscore why it is the correct answer in this context.
