Alcohol withdrawal syndrome: symptoms and risks

Alcohol withdrawal syndrome occurs when long-term heavy drinkers attempt to stop consuming alcohol abruptly. This reaction is driven by brain chemistry; because alcohol acts as a sedative, the nervous system compensates by increasing activity. When alcohol is suddenly removed, the brain enters a state of hyperactivity.

Common early symptoms, which typically appear within 6 to 12 hours of the last drink, include hand tremors, excessive sweating, anxiety, irritability, nausea, headaches, insomnia, and an accelerated heart rate. In severe cases, individuals may experience seizures, confusion, or high blood pressure.

Because sudden cessation can be physically dangerous, medical professionals advise seeking professional support rather than relying solely on willpower. Managing the transition may involve establishing new routines and maintaining proper hydration to mitigate physical and psychological discomfort.
