Alcoholism, now referred to as Alcohol Use Disorder (AUD), is a chronic brain disease that disrupts the usual functioning of the brain and other organs, causing serious harmful effects. While there is no single factor that determines whether someone becomes an alcoholic, there are several risk factors that can increase the likelihood of developing AUD. These factors include genetics, personality, mental health, environmental influences, and drinking patterns. Understanding these risk factors is crucial for early intervention and prevention strategies to address the widespread problem of AUD.

Genetics: People with a family history of alcoholism are more likely to become alcoholics themselves
While there is no single factor that determines whether a person will become an alcoholic, genetics play a significant role. Studies have shown that people with a family history of alcohol use disorder (AUD) are at an increased risk of developing the condition themselves. This is due to the influence of genes on various aspects of alcohol consumption and its effects. For example, genetics can determine how quickly the body breaks down alcohol, the severity of hangovers, the psychological impact of alcohol, and the likelihood of engaging in risky behaviours.
The heritability of AUD is estimated to be approximately 60%. This means that genetic factors account for 60% of the variability in the development of AUD among individuals. However, it's important to note that the genetics behind alcoholism are complex and not fully understood yet. Research has identified at least 51 genes that impact alcoholism, and it is believed that a large number of these genes interact with each other to influence an individual's risk.
One example of a genetic influence on alcoholism is found in individuals of East Asian descent. Approximately 36% of people with Chinese, Japanese, or Korean heritage carry variations in genes that affect the enzymes responsible for ethanol metabolism. These genetic variations can lead to a buildup of acetaldehyde, resulting in facial flushing, nausea, and increased heart rate when consuming alcohol. While this response may deter drinking, it also increases the risk of esophageal cancer, even among light drinkers.
In addition to genetics, other factors such as personality traits, expectations about alcohol, and environmental influences play a role in the development of alcoholism. For instance, individuals who are more risk-taking, less inhibited, or those who perceive alcohol positively may be more prone to heavy drinking. Growing up around family members with alcoholism can also shape one's attitude towards alcohol and increase the likelihood of developing unhealthy drinking habits.
While genetics can increase the risk for alcoholism, it's important to remember that it is not the sole determinant. Personal choices and lifestyle factors also come into play. Individuals who choose to abstain from alcohol or avoid social situations involving drinking are less likely to develop alcoholism. Additionally, seeking professional help and utilising treatment options such as behavioural therapies and support groups can effectively reduce alcohol consumption or achieve abstinence.

Mental health: Co-occurring mental health conditions, such as depression, anxiety, and bipolar disorder, can increase the risk of alcoholism
Mental health issues and alcoholism are closely linked. Alcohol use disorder (AUD) often co-occurs with other mental health disorders, and vice versa. The most common mental health disorders that co-occur with AUD are depressive disorders, anxiety disorders, trauma- and stress-related disorders, other substance use disorders, and sleep disorders. Bipolar disorder, attention deficit-hyperactivity disorder, and psychotic disorders such as schizophrenia also frequently co-occur with AUD.
People may drink alcohol to cope with symptoms of mental illness, even though alcohol ultimately exacerbates these problems. Conversely, alcohol use, especially during adolescence and long-term exposure, may predispose individuals to developing psychiatric disorders. AUD and psychiatric disorders often share genetic risks and environmental vulnerabilities such as trauma and adverse childhood experiences.
Depression and bipolar disorder are closely linked to alcoholism. Individuals who suffer from depression, bipolar disorder, and social anxiety are much more likely to develop alcoholism. Bipolar disorder is marked by extreme shifts in mood, and drinking alcohol can amplify these mood swings. People with bipolar disorder may use alcohol to try to manage their symptoms, particularly during manic episodes. According to a 2013 review, 45% of people with bipolar disorder also have AUD.
Anxiety is also a common co-occurring condition with AUD. Heavy drinking may be a sign of underlying anxiety, and individuals with anxiety disorders are more likely to develop alcoholism. Alcohol can cause individuals to act more impulsively, leading to actions such as self-harm or suicide.
If you are concerned about your drinking or feel it is affecting your mental health, it is important to seek help. Your GP can provide advice and support, and there are also local NHS alcohol addiction support services available.

Stress and trauma: External stress and traumatic experiences, especially during childhood, can lead to heavy drinking and an increased risk of alcoholism
Stress and trauma are significant risk factors for developing alcoholism, especially when experienced during childhood. External stress and traumatic experiences can lead individuals to engage in heavy drinking and increase their risk of alcoholism or alcohol use disorder (AUD).
While anyone can develop an unhealthy relationship with alcohol, certain factors can increase an individual's vulnerability. Stress and trauma are among the most potent environmental risk factors for AUD. Experiencing trauma, especially during childhood, or enduring significant stressors throughout life, can lead to heavy drinking patterns. This vulnerability can be further exacerbated by an individual's genetic makeup and drinking history.
The impact of stress and trauma on alcohol consumption is evident in various populations. For example, studies have shown that girls and women who have experienced abuse or trauma before adulthood are more prone to developing AUD. Additionally, adolescents facing multiple negative life events exhibit increased levels of drug use compared to those who have not faced such adversities.
The relationship between stress, trauma, and alcohol consumption is complex and influenced by biological, psychological, and social factors. For instance, individuals with post-traumatic stress disorder (PTSD) often experience AUD to a greater degree than those without PTSD. This comorbidity may reflect a self-medication hypothesis, where individuals with PTSD use alcohol to cope with their symptoms.
Furthermore, stress and trauma can interact with other risk factors to increase the likelihood of developing alcoholism. For example, individuals with certain psychological conditions, such as depression, bipolar disorder, or social anxiety, are more prone to alcoholism when exposed to stressful or traumatic events. Similarly, personality traits can play a role, as individuals who are less inhibited or seek risky behaviours may drink more heavily when facing stress or trauma.
While stress and trauma are significant risk factors, it is important to remember that the development of alcoholism is influenced by a multitude of factors, including personal choices, genetics, and environmental influences. Understanding these complex interactions can help identify high-risk individuals early on and provide effective interventions to prevent the progression of alcoholism.

Personality: Certain personality traits, such as risk-taking, disinhibition, and the desire to be the life of the party, can make individuals more susceptible to heavy drinking and alcoholism
An individual's personality can play a significant role in their susceptibility to heavy drinking and alcoholism. Certain traits, such as risk-taking behaviour, low inhibition, and the desire to be the centre of attention, can increase the chances of developing unhealthy drinking habits.
Risk-taking individuals tend to be more prone to heavy drinking and alcoholism. This tendency may stem from a willingness to experiment with alcohol and a disregard for potential negative consequences. Those who take risks are more likely to engage in binge drinking, which can lead to alcohol-related harm and increase the risk of developing an alcohol use disorder (AUD). Binge drinking during adolescence, in particular, is associated with other risky behaviours, including drug use, unprotected sex, and impaired driving.
Low inhibition is another personality trait that can contribute to heavy drinking. Alcohol is often associated with disinhibition, leading to increased social behaviour and impulsivity. Individuals with naturally lower levels of inhibition may find that alcohol exacerbates this trait, resulting in more frequent or excessive drinking. However, it is important to note that alcohol can have complex and varied effects on behaviour, and disinhibition alone does not fully explain alcohol's impact.
The desire to be the "life of the party" can also be a risk factor for alcoholism. Individuals with this personality trait may perceive that alcohol enhances their social desirability and makes them more "likable". As a result, they may become heavy social drinkers, relying on alcohol to boost their confidence or to create a more outgoing persona. This can lead to a dependence on alcohol to facilitate social interactions and an increased risk of developing alcoholism.
In addition to these personality traits, an individual's expectations about alcohol also play a significant role. People with positive expectations about alcohol's effects are more likely to develop alcoholism. This is particularly true if they believe that alcohol improves their social skills or enhances their personality. However, it is important to recognise that alcoholism is a complex disorder influenced by a combination of genetic, environmental, and personal factors.

Social influences: Peer pressure, drinking among friends and family, and living close to alcohol retail stores or bars can all influence an individual's drinking habits and increase the risk of alcoholism
Social influences play a significant role in an individual's drinking habits and can increase the risk of developing alcoholism or alcohol use disorder (AUD). Peer pressure, drinking among friends and family, and proximity to alcohol retail stores or bars are all social factors that can impact a person's relationship with alcohol.
Peer Pressure
Peer pressure is a common influence on drinking habits, especially during adolescence and young adulthood. The desire to fit in and be liked by peers can lead individuals to engage in drinking or binge drinking, even if they would not typically do so. This is particularly true when starting college or a new job, where individuals are seeking to make new friends and develop peer relationships. Heavy drinking during these formative years is associated with other risky behaviours, including tobacco and drug use, unprotected sex, conduct problems, and impaired driving.
Drinking Among Friends and Family
Friends and family can significantly influence an individual's drinking habits. Children exposed to alcohol abuse within the family from an early age are at a higher risk of developing unhealthy drinking patterns themselves. Alcoholism in a family member can also impact the emotional, financial, and social well-being of other family members, straining relationships and leading to negative feelings. Additionally, drinking can increase the likelihood of domestic disputes and violence, further affecting the individual's social circle.
Proximity to Alcohol Retail Stores or Bars
The proximity of alcohol retail stores or bars to an individual's home, school, or workplace can also influence their drinking habits. Studies have found that the availability of liquor stores within a certain radius is associated with an increased likelihood of alcohol consumption and heavy drinking in adolescents. This influence was particularly significant during early and middle adolescence, with liquor store proximity at age 14 being a predictor of alcohol intake at age 17. However, the impact seemed to lessen in late adolescence and young adulthood.

Frequently asked questions
Alcohol Use Disorder (AUD) is a medical condition characterized by an impaired ability to stop or control alcohol use despite adverse social, occupational, or health consequences. AUD is also referred to as alcohol abuse, alcohol dependence, alcohol addiction, or alcoholism.
There is no single cause of AUD or alcoholism. Risk factors include both internal and external factors. Internal factors include genetics, psychological conditions, personality, personal choice, and drinking history. External factors include family, environment, religion, social and cultural norms, age, education, and job status.
Biological children of alcoholics are more likely to become alcoholics themselves, regardless of whether they are raised by alcoholics or non-alcoholics. This is due to a combination of many genes that interact with one another. At least 51 genes that impact alcoholism have been discovered.
Excessive drinking increases the risk of developing AUD. Drinking is considered excessive or unhealthy when it causes health or social problems. For men, this is typically defined as more than 4 drinks per day or 14 drinks per week. For women, it is more than 3 drinks per day or 7 drinks per week.
Signs and symptoms of AUD include consuming alcohol in greater quantities or for longer than planned, unsuccessful attempts to reduce alcohol use, and spending a lot of time acquiring, using, or recovering from alcohol. AUD can also lead to social, economic, or health problems caused by drinking.
