An alcoholic person is someone who has a physical and psychological dependence on alcohol. This dependence is characterized by a pattern of compulsive and uncontrollable alcohol use, despite the negative consequences that it may have on their health, work, family life, and other areas of their life. The signs and symptoms of alcoholism may include increased tolerance to alcohol, withdrawal symptoms when trying to quit, loss of control over drinking, continued use of alcohol despite negative consequences, and giving up activities that were once enjoyed to drink alcohol. Alcoholism can have serious physical, psychological, and social consequences, and treatment is often necessary to help individuals overcome their addiction.
