Alcohol poisoning is an overdose of alcohol that occurs when a person drinks so much that the body cannot process it quickly enough. The result is that blood alcohol levels rise to dangerous levels, causing breathing, body temperature, and heart rate to slow. Without emergency care a person suffering from alcohol poisoning can die. Signs include vomiting, confusion, slowed breathing and pulse, unresponsiveness, and loss of consciousness. Emergency treatment can save the life of someone with alcohol poisoning, but only if begun in time.
