Alcohol addiction, also known as alcoholism or alcohol use disorder, is a condition where a person has an uncontrollable desire to consume alcohol despite negative consequences, such as health problems, work difficulties, and personal or legal issues. It is considered an addiction when a person has developed a physical or psychological dependence on alcohol, making it difficult or impossible to quit drinking without professional help. A healthcare professional can diagnose alcohol addiction based on a set of criteria outlined in the Diagnostic and Statistical Manual of Mental Disorders (DSM-5).
