Alcohol addiction, also known as alcoholism or alcohol use disorder, is a chronic and progressive disease that is characterized by an uncontrollable and compulsive use of alcohol despite negative consequences. It is typically diagnosed when an individual meets certain criteria as defined in the DSM-5 (Diagnostic and Statistical Manual of Mental Disorders, 5th edition), such as a strong desire or urge to drink, difficulty controlling or limiting alcohol use, continued use of alcohol despite knowing it is causing or worsening physical or psychological problems, and withdrawal symptoms when trying to stop drinking. The severity of alcohol addiction can vary from mild to severe, and treatment may involve a combination of medication, therapy, and support groups.
