Problem drinking has multiple causes, with genetic, physiological, psychological and social factors all playing a role. For some alcohol abusers, psychological traits such as impulsiveness, low self-esteem and a need for approval prompt inappropriate drinking. Others drink as a way of coping with emotional pain. Once people begin drinking excessively, the problem can perpetuate itself. Heavy drinking can cause physiological changes that make more drinking the only way to avoid discomfort.
Genetic factors render some people especially vulnerable to alcohol dependence.
Yet a family history of alcoholism doesn't mean that children of alcoholics will automatically grow up to become alcoholics themselves. Environmental factors such as peer pressure and the easy availability of alcohol can also play key roles. Although alcohol-related disorders can strike anyone, poverty and physical or sexual abuse also increase the odds. While small amounts of alcohol may have some beneficial physical effects, heavy drinking can cause serious health problems and even death. Many problems aren't apparent until they become serious, however.
