Alcohol detox is considered to be the most dangerous type of withdrawal that someone can experience. The risk of dying from alcohol detox increases significantly when delirium tremens occurs, especially if it is not treated professionally. Even without delirium tremens, alcohol withdrawal during detox can cause seizures, hallucinations and other symptoms that can increase the risk of injury or death. Having professional medical support during detox can be life-saving if you are a heavy drinker.
