What is a significant risk when someone using alcohol suddenly stops?

The significant risk associated with someone who is using alcohol suddenly stopping is the potential for seizures. This phenomenon is part of a condition known as alcohol withdrawal syndrome, which can occur when an individual who has been consuming alcohol regularly suddenly decreases or stops their intake.

During prolonged alcohol use, the body becomes dependent on its presence to function normally. When alcohol is removed abruptly, the central nervous system can become overstimulated due to the lack of its depressant effects. This increased excitability can manifest in various symptoms, including tremors, anxiety, and in severe cases, seizures. Withdrawal seizures typically occur 6 to 48 hours after the last drink, highlighting a critical need for medical supervision when someone with a history of alcohol use decides to quit.

The other options, such as increased appetite, enhanced immune function, and improved sleep quality, do not accurately reflect the physiological responses to sudden alcohol cessation. Rather, individuals are more likely to experience decreased appetite, immune suppression, and sleep disturbances during withdrawal, making the risk of seizures the most relevant concern here.
