Which of the following is NOT an effect of alcohol on the body?

In the context of the effects of alcohol on the body, increased reflexes is not a typical outcome. Alcohol is a central nervous system depressant, and its consumption generally leads to slower reaction times and impaired motor coordination. This sedative effect can result in a reduced ability to respond quickly and effectively to stimuli, thus diminishing reflexes rather than enhancing them.

Understanding the other effects listed is crucial: hypoglycemia can occur because alcohol influences glucose metabolism, leading to dangerously low blood sugar levels. Fatty liver is a condition that can develop from the excessive consumption of alcohol, resulting in the accumulation of fat in liver cells. Cardiac arrhythmia, which refers to irregular heartbeats, can also be a serious effect of drinking alcohol, particularly in higher amounts or among those with existing heart conditions. Each of these conditions highlights how alcohol can negatively impact various bodily functions and systems.
