What are causes of Alcoholism

Causes

Genetic, psychological, social and environmental factors can impact how drinking alcohol affects your body and behaviour. Theories suggest that for certain people drinking has a different and stronger impact that can lead to alcohol use disorder.

Over time, drinking too much alcohol may change the normal function of the areas of your brain associated with the experience of pleasure, judgment and the ability to exercise control over your behaviour. This may result in craving alcohol to try to restore good feelings or reduce negative ones.

Risk factors

Alcohol use may begin in the teens, but alcohol use disorder occurs more frequently in the 20s and 30s, though it can start at any age.

• Steady drinking over time. Drinking too much on a regular basis for an extended period or binge drinking on a regular basis can lead to alcohol-related problems or alcohol use disorder.
• Starting at an early age. People who begin drinking — especially binge drinking — at an early age are at a higher risk of alcohol use disorder.
• Family history. The risk of alcohol use disorder is higher for people who have a parent or other close relative who has problems with alcohol. This may be influenced by genetic factors.
• Depression and other mental health problems. It's common for people with a mental health disorder such as anxiety, depression, schizophrenia or bipolar disorder to have problems with alcohol or other substances.
• History of trauma. People with a history of emotional or other trauma are at increased risk of alcohol use disorder.
• Having bariatric surgery. Some research studies indicate that having bariatric surgery may increase the risk of developing an alcohol use disorder or of relapsing after recovering from alcohol use disorder.
• Social and cultural factors. Having friends or a close partner who drinks regularly could increase your risk of alcohol use disorder. The glamorous way that drinking is sometimes portrayed in the media also may send the message that it's OK to drink too much. For young people, the influence of parents, peers and other role models can impact risk.
