Alcohol use disorder, commonly known as alcoholism, is a prevalent medical condition that can lead to severe health issues. Alcoholism is characterised by an inability to stop drinking, even when it negatively impacts health, safety, and personal relationships. Excessive alcohol consumption can have detrimental effects on multiple organs and body systems. It increases the risk of various cancers, including liver, breast, head and neck, oesophageal, and colorectal cancers. Heavy drinking can also lead to endocrine system disruptions, causing thyroid issues, abnormal cholesterol, reproductive problems, and diabetes. Alcoholism is associated with mental health conditions such as depression and anxiety, and it can exacerbate existing issues like post-traumatic stress disorder (PTSD) and attention-deficit/hyperactivity disorder (ADHD). Additionally, alcohol withdrawal can result in life-threatening symptoms, including alcohol-induced hepatitis, alcohol poisoning, cerebellar degeneration, cirrhosis, and delirium tremens. The harmful effects of alcohol extend beyond the individual, impacting communities and leading to social issues and injuries, including road traffic accidents.

Alcohol use disorder
The risk factors for developing AUD include the amount, frequency, and speed of alcohol consumption. Other factors include drinking at an early age, with those starting before the age of 15 being more likely to develop AUD. Genetics and family history also play a role, with hereditability accounting for approximately 60%. Mental health conditions and a history of trauma are also associated with AUD.
The symptoms of AUD include craving beverages containing alcohol, experiencing alcohol withdrawal symptoms, and drinking to avoid these symptoms. People with AUD may also spend a lot of time obtaining and consuming alcohol or recovering from hangovers. They may also repeatedly try to reduce their alcohol intake and fail to meet work or family obligations due to their drinking.
AUD can be treated with medication and behavioural therapy. Three medications approved by the U.S. Food and Drug Administration to help reduce drinking and prevent relapse are naltrexone, acamprosate, and disulfiram. Behavioural treatments, such as alcohol counselling or talk therapy, aim to change drinking behaviour and build motivation to stop drinking. Mutual-support groups also provide peer support for reducing or stopping alcohol consumption.
While AUD can significantly impact a person's life, effective treatments are available, and most people can reduce their alcohol intake or stop drinking entirely with the right help and support.

Cancer
Alcohol consumption, even at low levels, can have negative health effects. However, most alcohol-related harm comes from heavy drinking or continuous alcohol consumption. Alcohol is a toxic, psychoactive substance with dependence-producing properties. It is also a known human carcinogen, increasing the risk of several cancers.
Alcohol consumption has been linked to an increased risk of various cancers, including breast, liver, head and neck, oesophageal, and colorectal cancers. In 2019, about 4.4% of cancers diagnosed worldwide, amounting to 401,000 cancer deaths, were attributed to alcohol consumption. Alcohol consumption is estimated to have caused over 538,000 cancer cases in the United States in 2022, with about 86% of these new alcohol-associated cancers occurring in individuals aged 50 or older.
The International Agency for Research on Cancer (IARC) categorises alcohol as a Group 1 carcinogen, due to sufficient evidence linking it to cancers of the oral cavity, pharynx, larynx, oesophagus, and liver. Alcohol consumption can increase the levels of hormones like estrogen, which is a factor in breast cancer development. Additionally, alcohol makes it easier for the cells in the mouth and throat to absorb harmful chemicals, such as carcinogens from tobacco smoke, increasing the risk of mouth and upper throat cancers.
Studies have also suggested a potential link between alcohol consumption and an elevated risk of melanoma, pancreatic, prostate, and stomach cancers. However, it is important to note that the association between alcohol use and cancers of the bladder, ovary, and uterus is less clear or inconsistent. While some studies indicate a decreased risk of kidney cancer, thyroid cancer, and non-Hodgkin lymphoma with alcohol consumption, the overall number of cases prevented is much lower than the total cancer cases attributable to alcohol.
The risk of cancer increases with the amount of alcohol consumed, and even light drinkers have an elevated risk compared to non-drinkers. Binge drinking, defined as consuming four or more drinks for women and five or more drinks for men in about two hours, further exacerbates the health risks. Reducing alcohol consumption is crucial for lowering the risk of cancer and improving overall health and well-being.

Liver disease
Alcoholic liver disease is liver damage caused by alcohol abuse. The liver is one of the most complex organs in the body, serving a wide variety of functions, including detoxifying blood and producing bile to aid digestion. Each time the liver filters alcohol, some liver cells die, and while the liver can develop new cells, prolonged alcohol misuse over many years can reduce its ability to regenerate, resulting in serious and permanent damage. Alcoholic liver disease most often occurs after years of heavy drinking, and the chances of getting it increase with the duration and amount of alcohol consumed.
Alcoholic liver disease can be broken down into three stages of severity: fatty liver disease, alcoholic hepatitis, and cirrhosis. Fatty liver disease is reversible, and the liver should return to normal if an individual stops drinking alcohol for several months or years. Alcoholic hepatitis is a potentially serious condition that can be caused by alcohol misuse over a long period. It may be the first indication that a person is damaging their liver through alcohol consumption. Alcoholic hepatitis is usually reversible if an individual stops drinking permanently, but severe alcoholic hepatitis is a serious and life-threatening illness that claims many lives each year.
Cirrhosis is the final phase of alcoholic liver disease, where the liver has become significantly scarred. Even at this stage, there may not be any obvious symptoms. Cirrhosis is generally not reversible, but stopping alcohol consumption immediately can prevent further damage and significantly increase life expectancy. A liver transplant may be required in severe cases where the liver has stopped functioning and does not improve when alcohol consumption ceases.
The risk of developing alcoholic liver disease is higher for men and individuals between 40 and 50 years of age. Women may develop the disease after less exposure to alcohol than men. Some people may also have an inherited risk for the disease. Alcoholic liver disease does not occur in all heavy drinkers, and there may be no symptoms, or symptoms may develop slowly, depending on how well the liver is functioning. Symptoms tend to be more pronounced after a period of heavy drinking and may include confusion, memory problems, insomnia, and changes in personality caused by a buildup of toxins in the brain. Other possible symptoms include passing black, tarry stools, vomiting blood, and a tendency to bleed and bruise more easily.

Mental health
Alcohol use disorder (AUD), or alcoholism, is a common condition where individuals are unable to stop drinking despite the negative impact on their health, safety, and personal relationships. AUD is associated with various mental health issues, which can both cause and result from excessive alcohol consumption.
AUD treatment often addresses mental health issues through behavioural therapy and medication. Behavioural therapy helps individuals change their drinking behaviour and manage underlying mental health conditions. Medications like naltrexone, acamprosate, topiramate, and gabapentin can reduce cravings and support recovery. Support groups also play a vital role in providing connection and understanding during treatment.
The relationship between mental health and alcoholism is complex and bidirectional. Addressing both aspects is crucial for effective AUD treatment and improving overall mental well-being. While most people with AUD can reduce their alcohol consumption or achieve abstinence, relapses may occur due to stressful events or underlying mental health triggers. Thus, ongoing support and treatment are essential to help individuals manage their drinking and associated mental health challenges.

Accidents and injuries
Alcohol consumption, even at low levels, can have health risks. However, most alcohol-related harm comes from heavy drinking. Alcohol contains ethanol, a psychoactive and toxic substance that can induce dependence. In 2019, 2.6 million deaths worldwide were attributable to alcohol consumption, with 2 million of those among men. Alcohol is associated with a range of health risks, including liver disease, heart disease, and cancer. It also increases the risk of accidents and injuries.
Alcohol intoxication impairs judgment, coordination, and reaction time, increasing the risk of accidents. Traffic crashes are a leading cause of injury and death related to alcohol. In the United States, about 30% of traffic crash fatalities involve drunk drivers, with an average of 11,000 people dying annually from 2014 to 2023. Drunk driving is illegal in all states, and offenders face severe penalties, including fines, jail time, and driver's license revocation. Despite these measures, drunk driving remains prevalent, especially among young adults, with one person killed in a drunk-driving crash every 42 minutes in 2023.
In addition to traffic accidents, alcohol increases the risk of other types of injuries, including falls, drownings, and burns. It also contributes to interpersonal violence, self-harm, and suicide, which are considered intentional injuries. Alcohol abuse by parents and caregivers also increases the risk of child physical injury and maltreatment. The harmful effects of alcohol extend beyond the individual, impacting families and communities.
The impact of alcohol on accidents and injuries is influenced by various factors, including the volume of alcohol consumed, drinking patterns, and societal norms. Binge drinking and heavy continuous drinking are particularly harmful and can lead to immediate and long-term health consequences. Lowering alcohol consumption is essential to reducing the risk of accidents and injuries associated with alcohol abuse.

Frequently asked questions
Alcoholism, or alcohol use disorder, is a common medical condition that can lead to a range of health problems, including liver disease, heart disease, and cancer. Alcoholics may also experience mental health issues such as depression and anxiety, as well as social and relationship problems. Alcoholics are also more susceptible to injuries and accidents, with a single binge-drinking episode significantly increasing the likelihood of motor vehicle crashes, falls, and burns.
If someone is craving their next drink, it may be a sign that they have alcohol use disorder. Other signs include continuing to drink even when it affects one's health, safety, and personal relationships. Additionally, binge drinking (four or more drinks for women, or five or more drinks for men during an occasion) and heavy drinking (eight or more drinks for women, or 15 or more drinks for men during a week) are signs of problematic alcohol use.
Treatment for alcohol use disorder includes medication and behavioral therapy. Medications such as naltrexone and acamprosate are approved by the U.S. Food & Drug Administration to treat alcohol use disorder. Behavioral treatment involves counseling with addiction counselors or psychologists to change drinking behavior. Support groups can also provide connections with others who understand the situation.
