Which of the following is a potential consequence of long-term alcohol abuse?

Long-term alcohol abuse can lead to a variety of serious health issues, one of which is liver damage. The liver is responsible for metabolizing alcohol, and excessive and prolonged consumption can overwhelm its capacity to process it. This can result in conditions such as fatty liver, alcoholic hepatitis, fibrosis, and ultimately cirrhosis, which can severely impair liver function and lead to life-threatening complications.

In contrast, improved cognitive function, enhanced physical fitness, and increased social engagement are not consequences associated with long-term alcohol use. Alcohol typically impairs cognitive abilities, negatively affects physical health and fitness levels due to its impact on coordination and stamina, and can lead to isolation or strained relationships rather than enhancing social engagement. Thus, the correct response highlights a well-documented and serious consequence of chronic alcohol abuse.
