Alcohol use disorder (AUD), commonly known as alcoholism, is a prevalent medical condition characterised by an impaired ability to stop or control alcohol consumption despite adverse social, occupational, or health consequences. It is considered a brain disorder and can range from mild to severe. The risk factors for developing AUD include the amount, frequency, and speed of alcohol consumption, with binge drinking and heavy alcohol use being significant contributors. Genetic predispositions and mental health conditions, such as depression, PTSD, or ADHD, also play a role in the development of AUD. The harmful effects of alcohol misuse can lead to various health complications, including liver disease, cardiomyopathy, and an increased risk of certain cancers. Treatment for AUD typically involves medication and behavioural therapy, with evidence-based approaches showing that most individuals can reduce their alcohol intake or achieve abstinence.

What You'll Learn
Withdrawal symptoms
Alcohol withdrawal symptoms can range from mild to severe and life-threatening. They typically begin within six to 24 hours of stopping or significantly decreasing heavy, long-term alcohol use. Mild symptoms include headache, mild anxiety, and insomnia, which can begin to appear six to 12 hours after the last drink.
More serious symptoms can start to occur 12 to 48 hours after the last drink and may include hallucinations and seizures. Symptoms are often at their worst between 24 and 72 hours after the last drink, but some may linger for weeks or even months. Prolonged withdrawal symptoms can include insomnia and mood changes.
Delirium tremens (DTs) is a severe form of alcohol withdrawal that can be fatal. It can cause serious symptoms such as changes in brain activity, and it affects 1%-1.5% of people with alcohol withdrawal. DTs symptoms typically begin around 72 hours after the last drink and can continue for several days, becoming most intense four to five days after the last drink.
The severity and length of alcohol withdrawal vary depending on several factors, including the amount of alcohol usually consumed and the duration of alcohol use. Withdrawal symptoms can be managed and treated through medication and therapy. It is important to seek medical help if concerning symptoms of alcohol withdrawal occur.

Interference with daily life
Alcohol use disorder (AUD) is a medical condition characterised by an impaired ability to stop or control alcohol use despite adverse social, occupational, or health consequences. It is a brain disorder that can be mild, moderate, or severe, and is often perpetuated by lasting changes in the brain caused by alcohol misuse. AUD can turn your life upside down and interfere with your daily life in several ways.
Firstly, AUD can lead to social problems, including issues with family and friends. People with AUD may continue to drink even when it causes trouble in their relationships or damages their personal connections. They may also experience family problems, issues at work, financial difficulties, and unemployment.
Secondly, AUD can interfere with daily life by impacting an individual's ability to take care of essential tasks and responsibilities. This may include difficulties in maintaining a job, performing well at school, or taking care of their home and family due to the negative effects of drinking or being sick from drinking.
Additionally, AUD can cause individuals to give up or cut back on activities they once enjoyed or found important, interesting, or pleasurable. They may start planning their lives around their next drink, neglecting hobbies, social engagements, or self-care practices that were once a priority.
Furthermore, AUD can lead to risky behaviours and increased chances of getting hurt. Individuals may engage in activities such as driving, swimming, using machinery, walking in dangerous areas, or having unprotected sex while intoxicated, which can have severe consequences for their safety and well-being.
AUD can also interfere with daily life by exacerbating or contributing to mental health issues. Individuals may experience depression, anxiety, or other mental health conditions that are made worse by alcohol consumption. They may continue to drink even when it adds to these existing problems, creating a cycle of negative reinforcement.
In summary, AUD has the potential to significantly disrupt an individual's life across various domains, including social relationships, occupational functioning, personal interests and activities, safety, and mental health. Recognising these signs of interference in daily life is crucial for seeking appropriate treatment and support.

Health consequences
Alcohol use disorder (AUD), commonly known as alcoholism, is a medical condition characterised by a person's inability to stop or control their alcohol consumption despite adverse social, occupational, or health consequences. AUD can be mild, moderate, or severe, and it is considered a brain disorder. People with AUD experience lasting changes in the brain that perpetuate the disorder and make them vulnerable to relapses.
Excessive alcohol consumption, whether on a single occasion or over time, can have serious health consequences. Alcohol affects not just the liver but also the brain, gut, pancreas, lungs, cardiovascular system, immune system, and more. It interferes with the brain's communication pathways, impacting mood, behaviour, and cognitive abilities.
Short-term Health Consequences
Alcoholism can lead to acute alcohol-related medical emergencies and even death. A single binge-drinking episode significantly increases the risk of motor vehicle crashes, atrial fibrillation, drowning, trauma, falls, burns, suicides, and overdoses, especially when combined with other sedating drugs. Alcohol poisoning is also a severe risk, as high blood alcohol levels can interfere with vital body functions like breathing and heart rate.
Long-term Health Consequences
Long-term heavy drinking has numerous health consequences, including:
- Cancer: Alcohol is a chemical carcinogen, and heavy, long-term consumption increases the risk of several types of cancer, including oesophageal, head and neck cancers, and oral cavity cancers. Even low levels of alcohol consumption have been linked to an increased risk of cancer.
- Cardiovascular Issues: Alcohol consumption is associated with an increased risk of cardiovascular events and high blood pressure.
- Liver Disease: Excessive drinking can lead to liver disease and cirrhosis of the liver.
- Immune System Weakening: Alcohol impairs the body's immune response, increasing the likelihood of respiratory infections and conditions like Acute Respiratory Distress Syndrome (ARDS). It also increases the risk of developing COVID-19 and exacerbating its severity.
- Digestive Problems: Alcohol can contribute to a 'leaky gut', allowing toxins to enter the body and disrupting the gastrointestinal tract's microbiota.
- Mental Health: Alcoholism is associated with mental health conditions such as depression, anxiety, and an increased risk of suicide. It can also lead to memory problems, including dementia.
- Endocrine-related Issues: Alcohol can contribute to thyroid diseases, abnormal cholesterol levels, reproductive dysfunction, stress intolerance, and diabetes.
- Social and Occupational Problems: Alcoholism can lead to relationship issues with family and friends, job troubles, and problems at school or work.

Increased tolerance
Alcohol tolerance is defined as the bodily responses to the functional effects of ethanol, including direct tolerance, speed of recovery from insobriety, and resistance to the development of alcohol use disorder (AUD). Increased alcohol tolerance is a sign of alcohol dependence, which is characterized by an impaired ability to stop or control alcohol use despite adverse consequences.
Alcohol tolerance is influenced by various factors, including the amount, frequency, and speed of alcohol consumption. Regular and heavy alcohol consumption increases tolerance, leading to reduced sensitivity to the physical effects of alcohol. As a result, individuals may need to consume higher quantities of alcohol to achieve the desired effects, which can result in physical damage and impairment without their knowledge. This can include impaired reaction time and peripheral vision, increasing the risk of engaging in activities that could cause harm, such as driving.
The development of alcohol tolerance is also influenced by genetic factors and varies among different ethnic groups. For example, Native Americans have a higher probability of developing AUD compared to Europeans and Asians, and different alcohol tolerance exists within Asian groups, such as between Chinese and Koreans. Higher body mass and the prevalence of high levels of alcohol dehydrogenase, an enzyme responsible for breaking down alcohol, also contribute to increased alcohol tolerance.
Chronic alcohol use can lead to liver damage, resulting in a buildup of fat and scar tissue. This reduces the liver's ability to metabolize alcohol, causing small amounts of alcohol to lead to a high blood alcohol concentration (BAC) and more rapid intoxication. This phenomenon is known as "reverse tolerance," where individuals with liver damage can experience higher intoxication levels with lower alcohol consumption.
Tolerance to alcohol can also be understood through neurobiological aspects, such as the activation of separate neurocircuits that contribute to hyperkatifeia, which is associated with acute alcohol withdrawal. Studies have shown that repeated alcohol consumption strengthens the b-process, leading to a faster onset, greater intensity, and prolonged duration of negative emotional and motivational symptoms associated with withdrawal.
It is important to recognize that building alcohol tolerance is a sign of progressing toward physical addiction. However, it is possible to reduce tolerance by abstaining from alcohol for a significant amount of time.

Family history
A family history of alcoholism is a strong indicator of a predisposition to alcoholism. Studies have shown that children of alcoholics are about four times more likely than the general population to develop alcohol problems. This is due to a combination of genetic and environmental factors. Research has shown that those who begin drinking at an early age are more likely to develop Alcohol Use Disorder (AUD) or alcoholism, perhaps due to the interplay between genetics and environmental factors.
Genetics play a significant role in the development of alcoholism, with hereditability accounting for approximately 60%. Scientists have identified more than 400 locations in the human genome and at least 566 variants within these locations that could influence alcohol misuse. Genes that relate to alcohol metabolism, particularly ADH1B and ALDH2, are closely tied to the risk for problem drinking. However, it's important to note that there is no single "alcohol gene" that leads to the development of AUD.
The risk of developing alcoholism increases with a stronger family history, such as having multiple alcoholic relatives. For example, a study on U.S. Hispanics found that alcohol dependence symptoms were associated with a stronger family history of alcoholism and later generational status. This suggests that heritability for alcoholism is influenced by higher-order environmental factors, such as the relaxation of social restrictions on drinking.
While a family history of alcoholism increases the risk, it does not guarantee that an individual will become an alcoholic. Many children of alcoholics do not develop drinking problems, even in troubled families. The risk is higher, but it is not inevitable. Environmental factors also play a role, and seeking professional help or support from family and friends can be proactive measures to reduce the risk of developing AUD.
If you have a family history of alcoholism, it is important to approach moderate drinking carefully. Maintaining moderate drinking habits may be more challenging for those with a family history of alcohol problems. Once an individual moves from moderate to heavier drinking, the risks of social and medical problems increase significantly. It is recommended to seek advice from a health care professional if you have concerns about your drinking habits or family history.
