Alcoholism
Alcohol also affects other body systems. Irritation of the gastrointestinal tract can occur with erosion of the lining of the esophagus and stomach causing nausea and vomiting, and possibly bleeding. Vitamins are not absorbed properly, which can lead to nutritional deficiencies with the long-term use of alcohol. Liver disease, called alcoholic hepatitis, may also develop and can progress to cirrhosis. The heart muscle may be affected. Sexual dysfunction may also occur, causing problems with erections in men and cessation of menstruation in women. Alcohol affects the nervous system and can result in nerve damage and severe memory loss. Chronic alcohol use also increases the risk of cancer of the larynx, esophagus, liver, and colon. Alcohol consumption during pregnancy can cause severe birth defects. The most serious is fetal alcohol syndrome, which may result in mental retardation and behavior problems. A milder form of the condition which can still cause lifelong impairment is called fetal alcohol affects. The social consequences of problem drinking and alcohol dependence can be as serious as the medical problems. People who abuse or are dependent on alcohol have a higher incidence of unemployment, domestic violence, and problems with the law. About half of all traffic deaths are related to alcohol use.

The development of dependence on alcohol may occur over a period of years, following a relatively consistent pattern. At first, a tolerance of alcohol develops. This results in a person being able to consume a greater quantity of alcohol before its adverse effects are noticed. Memory lapses (black-outs) relating to drinking episodes may follow tolerance. Then, people may lose control over drinking and find it difficult or impossible to stop if they try. The most severe drinking behavior includes prolonged binges of drinking with associated mental or physical complications. Some people are able to gain control over their dependence in earlier phases before a total lack of control occurs. The problem is, no one knows which heavy drinkers will be able to regain control and which will not.
