Alcohol Withdrawal
Why stopping suddenly can be risky.
What Is Alcohol Withdrawal?
lcohol withdrawal occurs when a person who has developed physical dependence on alcohol suddenly reduces or stops drinking. The symptoms can range from mild to severe. Some people may experience anxiety, sweating, shaking or nausea, while severe withdrawal can involve seizures, hallucinations, severe confusion or delirium tremens (DTs). Because severe alcohol withdrawal can be life-threatening, people who may be physically dependent on alcohol should seek medical advice before stopping suddenly. Illustration: Alcohol withdrawal
