Alcohol dependence, also known as alcoholism or alcohol use disorder (AUD), is a condition that results from the excessive consumption of alcoholic beverages. It is characterised by a strong craving for alcohol, an inability to control drinking habits, and the presence of withdrawal symptoms when attempting to reduce or stop alcohol consumption. People with alcohol dependence often prioritise drinking over other activities and obligations, such as work or family, and may continue drinking despite the negative consequences on their physical and mental health. The development of alcohol dependence can be influenced by various factors, including genetics, family history, mental health conditions, and traumatic experiences. Treatment options for alcohol dependence include behavioural therapy, medication, and support groups, with the specific approach depending on the severity of the condition.

Alcohol dependence can cause poor mental health, including anxiety, depression, and suicidal feelings
Alcohol dependence can have detrimental effects on mental health, including increased risks of anxiety, depression, and suicidal feelings.
Anxiety
Anxiety is a common feeling after drinking alcohol, especially in those who already suffer from anxiety and depression. When drinking, there is an influx of GABA (gamma-aminobutyric acid), which causes feelings of relaxation and calmness. However, when the drinking stops, the body experiences withdrawal symptoms, and the absence of the crutch of alcohol can lead to heightened anxiety. Interrupted sleep, which often occurs after excessive drinking, can further worsen these anxious feelings. This creates a vicious cycle where individuals drink to alleviate anxiety, only to experience even worse anxiety after the drinking episode. Over time, individuals may become dependent on alcohol to function daily, using it as a coping mechanism for their anxiety.
Depression
There is a clear bidirectional relationship between alcohol use disorder (AUD) and depressive disorders. Both disorders increase the risk of the other, and each can worsen the symptoms of the other. Alcohol can directly cause depressive symptoms, but it can also worsen pre-existing depressive symptoms or increase the risk for those who are genetically vulnerable to depression. For some, alcohol becomes a way to self-medicate and alleviate depressive symptoms, further reinforcing the cycle of alcohol dependence. It is important to note that depressive symptoms caused by alcohol may subside after significantly reducing or stopping alcohol consumption.
Suicidal Feelings
There is a strong association between regular heavy drinking and suicidal thoughts, attempts, and death by suicide. Binge drinking has been linked to impulsive behavior, which can contribute to the increased risk of suicide. Additionally, the long-term physical and mental health consequences of alcohol dependence can also play a role in suicidal ideation. Men are at higher risk of suicide and are more likely to turn to alcohol when under stress. However, it is important to recognize that suicidal thoughts can affect anyone, regardless of age, gender, or background, and support is available for those struggling with alcohol dependence and suicidal ideation.

Withdrawal symptoms can be life-threatening and include seizures, hallucinations, and delirium tremens
Alcohol dependence, also known as alcoholism or alcohol use disorder (AUD), can lead to serious health concerns, including withdrawal symptoms that can be life-threatening. While alcohol withdrawal can be a challenging and dangerous process, it is important to understand the risks and seek appropriate medical support to ensure safety and well-being.
Withdrawal symptoms can vary in severity and may include seizures, hallucinations, and delirium tremens (DTs). Seizures can be a common symptom of alcohol withdrawal, and they can range from mild to severe. In some cases, seizures may indicate a more serious complication known as delirium tremens. Delirium tremens is a severe form of alcohol withdrawal that can be life-threatening. It is characterised by severe confusion, agitation, hallucinations, and seizures. This condition typically occurs within 48 to 96 hours after the last drink and requires immediate medical attention.
The risk of experiencing severe withdrawal symptoms, such as seizures and delirium tremens, is higher for individuals with a long history of heavy drinking or previous withdrawal symptoms. Additionally, certain factors, such as age, nutritional deficiencies, and co-occurring medical or mental health conditions, can increase the likelihood of severe withdrawal symptoms. It is crucial for individuals to undergo alcohol withdrawal under medical supervision, as healthcare professionals can monitor for these symptoms and provide appropriate interventions.
To manage alcohol withdrawal and prevent life-threatening complications, medical professionals may prescribe medications such as benzodiazepines to help reduce the severity of symptoms and the risk of seizures. Additionally, they may recommend a gradual reduction in alcohol consumption, known as detoxification, under their supervision. This process aims to minimise withdrawal symptoms and increase the chances of a safe and successful recovery. It is important to note that detoxification should not be attempted without medical guidance, as it can be dangerous and may lead to severe health consequences.
In addition to medical interventions, behavioural therapies play a crucial role in treating alcohol dependence and preventing relapse. Therapies such as cognitive-behavioural therapy (CBT) and mutual-support groups can help individuals develop coping strategies, manage triggers, and change their relationship with alcohol. These therapies aim to address the underlying psychological and behavioural aspects of alcohol dependence, empowering individuals to regain control over their lives and maintain long-term sobriety.

Alcohol dependence can lead to marital conflict, divorce, and domestic violence
Alcohol dependence can have detrimental effects on an individual's life, including their personal relationships and family life. It can lead to marital conflict, divorce, and domestic violence, causing profound issues in marriages and families.
Marital Conflict
Heavy drinking and alcohol disorders are often associated with marital conflict. Alcohol dependence can lead to negative emotions, interpersonal issues, and stress within the marriage, which can further motivate continued drinking. Alcohol can impair self-control and reduce the ability to resolve conflicts non-violently. It can also exacerbate existing problems, such as financial difficulties, childcare issues, infidelity, or other family stressors.
Divorce
Alcoholism can significantly impact the longevity of a marriage and lead to divorce. The negative behaviours associated with alcohol dependence, such as neglecting obligations, legal troubles, and deteriorating work performance, can cause resentment and detachment between spouses. In fault-based divorce states, alcoholism may be considered under grounds such as cruelty, neglect, or abandonment. Even in no-fault divorce states, alcoholism can influence settlement and custody decisions, with courts prioritising the best interests and safety of any children involved.
Domestic Violence
There are strong links between alcohol use and the occurrence of intimate partner violence (IPV). Alcohol consumption can increase the risk of perpetrating or experiencing IPV. It can impair self-control and cognitive and physical functions, making it more challenging to resolve conflicts peacefully. Additionally, societal beliefs that associate alcohol with aggression can further encourage violent behaviour. Studies have regularly identified the recent consumption of alcohol by perpetrators of IPV, and excessive drinking can exacerbate the severity of such incidents.

Children of people with alcohol dependence may develop emotional problems and self-image issues
Alcohol dependence, also known as alcohol use disorder (AUD), can have detrimental effects on the drinker's life, including their health, relationships, and ability to work. It can also have a significant impact on their children, who may develop emotional problems and self-image issues.
When a parent or primary caregiver has an alcohol problem, children in the home are exposed to a range of negative experiences, such as chaos, uncertainty, and disorganisation, emotional and/or physical neglect, instability, and arguments. This can cause children to experience anxiety, depression, antisocial behaviour, relationship difficulties, and behavioural issues. They may also develop a negative self-image and a range of emotional problems.
Children of alcoholics often do not have their basic needs met, including nutrition, safety, education, structure, consistency, affection, and healthcare. This can lead to feelings of insecurity and an inability to cope with social situations. They may also develop an unhealthy dependence on their caregivers, reflecting how they are viewed by those caregivers and authority figures. An absent parent with an alcohol use disorder may not provide their child with an accurate perception of themselves, leading to lifelong issues with self-image and self-esteem.
Furthermore, children of alcoholics are more likely to develop an alcohol use disorder themselves. This is due to a combination of genetic and environmental factors. The risk is influenced by the interplay between a person's genes and their environment, and children of alcoholics are four times more likely to develop an AUD themselves. This can lead to a cycle of alcohol dependence and the perpetuation of the disorder.
It is important to note that not all children of alcoholics will suffer the same effects, and some may experience minimal long-term consequences. However, for those who do experience negative impacts, the effects can last into adulthood, and it can be difficult to express emotions and form healthy relationships.

Alcohol misuse increases the risk of cancers of the mouth, throat, and breast, as well as other serious medical conditions like bowel cancer, pancreatitis, and high blood pressure
Alcohol misuse has severe health implications and is linked to an increased risk of several types of cancer and other serious medical conditions. Alcohol dependence can lead to a loss of control over consumption patterns, with individuals prioritizing drinking over other aspects of their lives. This can result in a range of harmful physical and psychological consequences, including an elevated risk of cancers of the mouth, throat, and breast, as well as bowel cancer, pancreatitis, and high blood pressure.
Alcohol is a known risk factor for cancers of the mouth and throat. Epidemiological studies have shown that alcohol consumption increases the risk of these cancers, with even light drinkers having a higher risk compared to non-drinkers. The combination of alcohol and tobacco use has a multiplicative effect on the likelihood of developing these cancers, significantly increasing the danger. The mouth and throat become more susceptible to absorbing harmful chemicals, such as those found in cigarette smoke, which can initiate cancer development.
Alcohol misuse is also associated with an increased risk of breast cancer. Studies have found a positive correlation between alcohol consumption and breast cancer risk, with women who consume one drink per day having higher chances than those drinking less than one drink weekly. Heavy and binge drinking further elevate this risk. Alcohol consumption can increase blood estrogen levels, which, at high concentrations, are linked to breast cancer development.
Additionally, alcohol misuse can contribute to the development of bowel cancer and pancreatitis. While research suggests that stopping alcohol consumption may reduce the risk of bowel cancer, the exact relationship between alcohol and this type of cancer requires further exploration. On the other hand, alcohol is a well-established cause of pancreatitis, an inflammation of the pancreas resulting in damage and dysfunction. Alcohol is the most common cause of acute and chronic pancreatitis, with alcohol-related pancreatitis more prevalent in Western countries and Japan.
The health consequences of alcohol misuse extend beyond cancer risks. Pancreatitis, for instance, can lead to severe complications, including organ failure and even death in rare cases. Moreover, alcohol dependence can cause physical withdrawal symptoms like shaking, sweating, and nausea when blood alcohol levels drop, making it dangerous to stop drinking without medical support. Thus, alcohol dependence is a serious condition that requires professional intervention, and individuals should consult their doctors or seek support from national alcohol services to address this complex health issue.

Frequently asked questions
Alcohol dependence, also known as alcoholism or alcohol addiction, is the most serious form of high-risk drinking, with a strong, often uncontrollable, desire to drink. It means drinking at a level that causes harm to one's health.
An early sign of dependence is when you need more alcohol to achieve the desired effect. As dependence progresses, you might find yourself spending most of your time thinking about alcohol or engaging in activities to obtain, consume, or recover from drinking. Other signs include increased tolerance, experiencing withdrawal symptoms such as shaking, sweating, nausea, and a strong urge to drink to avoid these symptoms.
Alcohol dependence can lead to serious health problems, including liver disease, cancers of the mouth, throat, breast, bowel, pancreatitis, high blood pressure, stroke, and coronary heart disease. It can also cause poor mental health, such as anxiety, depression, and suicidal thoughts, as well as relationship issues, financial problems, and aggression.
Treatment for alcohol dependence typically includes behavioural therapy, support groups, and medication. Behavioural therapy focuses on counselling to change drinking behaviour, while support groups provide connection and understanding. Medications such as naltrexone, acamprosate, disulfiram, and gabapentin can help reduce cravings and prevent relapse.
If you are concerned about someone's drinking, encourage them to seek professional help from a healthcare provider or support service. They can assess the severity of the problem and recommend appropriate treatment options, which may include inpatient or outpatient programmes, therapy, and medication. Support the person throughout their journey and provide a safe space for them to express their feelings.
