Alcohol withdrawal occurs when a person who has been drinking heavily for an extended period suddenly reduces or stops their alcohol intake. The body, which has become accustomed to the presence of alcohol, reacts to its absence. Symptoms can range from mild to severe and may include anxiety, tremors, sweating, and nausea. In some cases, withdrawal can lead to more serious complications, such as delirium tremens (DTs), which can cause confusion, hallucinations, and seizures. It is important for individuals experiencing withdrawal to seek medical assistance, as treatment can help manage symptoms and reduce risks associated with the process.
