Alcohol addiction, medically known as Alcohol Use Disorder (AUD), is a chronic condition in which a person cannot control or stop drinking despite harmful consequences. It affects the brain’s reward, motivation, and self-control systems, making alcohol a priority over responsibilities, relationships, and health. People with alcohol addiction may experience strong cravings, increased tolerance, and withdrawal symptoms such as anxiety, shaking, or nausea when not drinking. Over time, it can lead to physical, emotional, and social problems. Alcohol addiction treatment ranges from mild to severe and is treatable through therapy, medication, support groups, and lifestyle changes. Recovery is possible with proper support.
