While little detailed genetic research has been done, it has been shown that alcoholism tends to run in families with possible involvement of differences in alcohol metabolism and the genotype of alcohol-metabolizing enzymes.

Injury is defined as damage or harm that is done or sustained. The potential of injuring oneself or others can be increased after consuming alcohol due to the certain short term effects related to the substance such as lack of coordination, blurred vision, and slower reflexes to name a few. Due to these effects the most common injuries include head, fall, and vehicle related injuries. These include a range of soft tissue damage and fractures. A study was conducted between November 1, 2001 and June 30, 2002 of patients admitted to The Ulster Hospital in Northern Ireland with fall related injuries. They found that 113 of those patients admitted to that hospital during that had consumed alcohol recently and that the injury severity was higher for those that had consumed alcohol compared to those that hadn't. Another study showed that 21% of patients admitted to the Emergency Department of the Bristol Royal Infirmary had either direct or indirect alcohol related injuries. If these figures are extrapolated it shows that the estimated number of patients with alcohol related injuries are over 7000 during the year at this ED alone.

In the United States alcohol resulted in about 88,000 deaths in 2010.

There are a number of ways to preventing alcoholism throughout

adolescents. One of the main ways to do this is to "Promote an

understanding of underage alcohol consumption in the context of human

development and maturation that takes into account individual adolescent

characteristics as well as environmental, ethic, cultural and gender

differences". Another way in preventing underage drinking would be by reducing the cultural forces which are encouraging and

supporting underage drinking will also contribute to preventing adolescents from

consuming alcohol as a culture in which adolescents feel that it is acceptable,

will allow them to think that it is appropriate. Another important

component to preventing alcoholism throughout adolescence is the responsibility

of the government, to send a message to

underage drinkers informing them how themselves and the rest of society

strongly disapprove underage alcohol use because of the severe consequences it

can cause and also informing that it will not be tolerated.

Alcohol consumption by youth in the United States of America is an umbrella term for alcohol consumption by individuals under the age of 21 in the country.

Although the minimum legal age to purchase alcohol is 21 in all states (see National Minimum Drinking Age Act), the legal details vary greatly. While a few states completely ban alcohol usage for people under 21, the majority have exceptions that permit consumption.

Underage drinking has become an activity primarily done behind closed doors. Typically, underage drinkers hide their alcohol consumption by drinking quickly before they go out, which is often referred to as pregaming or pre-partying. Brittany Levine explained in her article "Pre-Gaming" in USA Today that "of all drinking events involving pre-partying, 80% involved additional drinking afterward." Those who oppose a complete ban on underage drinking argue that it is important that minors be introduced to alcohol in a controlled environment, so that supervision and guidance might occur instead of experimentation. Some parents are willing to provide alcohol for their children if they drink it in a controlled environment. Furnishing alcohol to one's own children is permitted in 31 states, while it's illegal to do so for other people's children in all fifty states. Social host ordinances have been enacted in a number of jurisdictions to attempt to limit the parties where adults may permit minors to drink. Social host laws or ordinances have proliferated in the last ten years because it has been too difficult for law enforcement to prove which adults furnished or served alcohol to minors in their own home, so it permits them to cite or arrest the adult who has control of the premises.

Alcohol is a liquid form substance which contains ethyl alcohol (also known formally as ethanol) that can cause harm and even damage to a persons DNA. "Alcohol consumption is recognized worldwide as a leading risk factor for disease, disability, and death." and is rated as the most used and abused substance by adolescences. Adolescence is a transitional stage of physical and psychological changes, usually a time in a person life in which they go through puberty. Combining these transitional stages and the intake of alcohol, can leave a number of consequences for an adolescent.

Youth treatment and intervention should focus on eliminating or reducing the effects of adverse childhood experiences, like childhood maltreatment, since these are common risk factors contributing to the early development of alcohol abuse. Approaches like contingency management and motivational interviewing have shown to be effective means of treating substance abuse in impulsive adolescents by focusing on positive rewards and redirecting them towards healthier goals. Educating youth about what is considered heavy drinking along with helping them focus on their own drinking behaviors has been shown to effectively change their perceptions of drinking and could potentially help them to avoid alcohol abuse.

Completely stopping the use of alcohol, or "abstinence," is the ideal goal of treatment. A strong social network and family support maybe important in achieving this goal.

Some people who abuse alcohol may be able to reduce the amount they drink, also called "drinking in moderation." If this method does not work, the person may need to try abstinence. Abstinence has been regularly achieved by many alcoholics in Alcoholics Anonymous.

Mindfulness-based intervention programs (that encourage people to be aware of their own experiences in the present moment and of emotions that arise from thoughts) can reduce the consumption of alcohol.

A study published in August 2010 in the journal, “Alcoholism: Clinical and Experimental Research,” followed 1,824 participants between the ages of 55 and 65 and found that even after adjusting for all suspected covariates, abstainers and heavy drinkers continued to show increased mortality risks of 51 and 45%, respectively, compared to moderate drinkers. A follow-up study lists several cautions in interpreting the findings. For example, the results do not address nor endorse initiation of drinking among nondrinkers, and persons who have medical conditions which would be worsened by alcohol consumption should not drink alcohol.

According to the National Institutes of Health, researchers now understand that drinking moderate amounts of alcohol can protect the hearts of some people from the risks of coronary artery disease.

But, it's not possible to predict in which people alcoholism will become a problem. Given these and other risks, the American Heart Association cautions people not to start drinking.

Preventing or reducing the harm has been called for via increased taxation of alcohol, stricter regulation of alcohol advertising and the provision of brief Interventions. Brief Interventions for alcohol abuse reduce the incidence of unsafe sex, sexual violence, unplanned pregnancy and, likely, STD transmission. Information and education on social norms and the harms associated with alcohol abuse delivered via the internet or face-to-face has not been found to result in any meaningful benefit in changing harmful drinking behaviours in young people.

According to European law, individuals who are suffering from alcohol abuse or other related problems cannot be given a license, or if in possession of a license cannot get it renewed. This is a way to prevent individuals driving under the influence of alcohol, but does not prevent alcohol abuse per se.

An individual's need for alcohol can depend on their family's alcohol use history. For instance, if it is discovered that their family history with alcohol has a strong pattern, there might be a need for education to be set in place to reduce the likelihood of reoccurrence (Powers, 2007). However, studies have established that those with alcohol abuse tend to have family members who try to provide help. In many of these occasions the family members would try to help the individual to change or to help improve the individual's lifestyle.

Topiramate, a derivative of the naturally occurring sugar monosaccharide D-fructose, has been found effective in helping alcoholics quit or cut back on the amount they drink. Evidence suggests that topiramate antagonizes excitatory glutamate receptors, inhibits dopamine release, and enhances inhibitory gamma-aminobutyric acid function. A 2008 review of the effectiveness of topiramate concluded that the results of published trials are promising, however, as of 2008, data was insufficient to support using topiramate in conjunction with brief weekly compliance counseling as a first-line agent for alcohol dependence. A 2010 review found that topiramate may be superior to existing alcohol pharmacotherapeutic options. Topiramate effectively reduces craving and alcohol withdrawal severity as well as improving quality-of-life-ratings.

The World Health Organization, the European Union and other regional bodies, national governments and parliaments have formed alcohol policies in order to reduce the harm of alcoholism. Targeting adolescents and young adults is regarded as an important step to reduce the harm of alcohol abuse. Increasing the age at which licit drugs of abuse such as alcohol can be purchased, the banning or restricting advertising of alcohol has been recommended as additional ways of reducing the harm of alcohol dependence and abuse. Credible, evidence based educational campaigns in the mass media about the consequences of alcohol abuse have been recommended. Guidelines for parents to prevent alcohol abuse amongst adolescents, and for helping young people with mental health problems have also been suggested.

The impact of alcohol on weight-gain is contentious: some studies find no effect, others find decreased or increased effect on weight gain.

Alcohol use increases the risk of chronic gastritis (stomach inflammation); it is one cause of cirrhosis, hepatitis, and pancreatitis in both its chronic and acute forms.

Drunkorexia is not a medically diagnosed disorder therefore there is no specific treatment. However, as drunkorexia is a combination of two different disorders, binge drinking and eating disorders such as anorexia and bulimia the treatment will need to address both.

Different countries recommend different maximum quantities. For most countries, the maximum quantity for men is 140 g–210 g per week. For women, the range is 84 g–140 g per week. Most countries recommend total abstinence during pregnancy and lactation.

Binge drinking is considered harmful, regardless of a person's age, and there have been calls for healthcare professionals to give increased attention to their patients drinking habits, especially binge drinking. Some researchers believe that raising the legal drinking age and screening brief interventions by healthcare providers are the most effective means of reducing morbidity and mortality rates associated with binge drinking. Programs in the United States have thought of numerous ways to help prevent binge drinking. The Centers for Disease Control and Prevention suggests increasing the cost of alcohol or the excise taxes, restricting the number of stores who may obtain a license to sell liquor (reducing "outlet density"), and implementing stricter law enforcement of underage drinking laws. There are also a number of individual counseling approaches, such as motivational interviewing and cognitive behavioral approaches, that have been shown to reduce drinking among heavy drinking college students. In 2006, the Wisconsin Initiative to Promote Healthy Lifestyles implemented a program that helps primary care physicians identify and address binge drinking problems in patients. In August 2008, a group of college presidents calling itself the Amethyst Initiative asserted that lowering the legal drinking age to 18 (presumably) was one way to curb the "culture of dangerous binge drinking" among college students. This idea is currently the subject of controversy. Proponents argue that the 21 law forces drinking underground and makes it more dangerous than it has to be, while opponents have claimed that lowering the age would only make the situation worse. Despite health warnings, most Australian women drink at least one night a week. But experts are warning they are not only damaging their bodies but are also at risk of attracting sexual predators.

Acute alcohol poisoning is a medical emergency due to the risk of death from respiratory depression and/or inhalation of vomit if emesis occurs while the patient is unconscious and unresponsive. Emergency treatment for acute alcohol poisoning strives to stabilize the patient and maintain a patent airway and respiration, while waiting for the alcohol to metabolize. This can be done by removal of any vomitus or, if patient is unconscious or has impaired gag reflex, intubation of the trachea using an endotracheal tube to maintain adequate airway:

Also:

- Treat hypoglycaemia (low blood sugar) with 50 ml of 50% dextrose solution and saline flush, as ethanol induced hypoglycaemia is unresponsive to glucagon.

- Administer the vitamin thiamine to prevent Wernicke-Korsakoff syndrome, which can cause a seizure (more usually a treatment for chronic alcoholism, but in the acute context usually co-administered to ensure maximal benefit).

- Apply hemodialysis if the blood concentration is dangerously high (>400 mg/dL), and especially if there is metabolic acidosis.

- Provide oxygen therapy as needed via nasal cannula or non-rebreather mask.

- Provide parenteral Metadoxine.

Additional medication may be indicated for treatment of nausea, tremor, and anxiety.

A normal liver detoxifies the blood of alcohol over a period of time that depends on the initial level and the patient's overall physical condition. An abnormal liver will take longer but still succeeds, provided the alcohol does not cause liver failure.

People having drunk heavily for several days or weeks may have withdrawal symptoms after the acute intoxication has subsided.

A person consuming a dangerous amount of alcohol persistently can develop memory blackouts and idiosyncratic intoxication or pathological drunkenness symptoms.

Long-term persistent consumption of excessive amounts of alcohol can cause liver damage and have other deleterious health effects.

Treatments for alcohol dependence can be separated into two groups, those directed towards severely alcohol-dependent people, and those focused for those at risk of becoming dependent on alcohol. Treatment for alcohol dependence often involves utilizing relapse prevention, support groups, psychotherapy, and setting short-term goals. The Twelve-Step Program is also a popular process used by those wishing to recover from alcohol dependence.

Drunkorexia is a colloquialism for self-imposed starvation or binge eating/purging combined with alcohol abuse. The term is generally used to denote the utilisation of extreme weight control methods (such as the aforementioned starvation or purging) as a tool to compensate for planned binge drinking.

Research on the combination of an eating disorder and binge drinking has primarily focused on the patterns of college-aged women, but the phenomenon has also been noted among young men. Studies show that college students engage in this combination of self-imposed malnutrition and binge drinking to avoid weight gain from alcohol. A study by the University of Missouri found that 30% of female college students admitted that within the last year they had restricted food in order to consume greater quantities of alcohol. The same study found that men are more likely engage in similar behavior in order to save money for purchasing alcohol. According to the study, 67% of students who restrict calories prior to alcoholic beverage consumption do so to prevent weight gain, while 21% did so to facilitate alcohol intoxication.

According to the Eating Disorder Center of Denver, of the participating college-aged females in an adjunct research study, about 75% met the criteria for alcohol abuse.

'Showbuzz', a CBS news site, has broadcast that, "Drunkorexia is a media coined term reflecting an alarmingly real trend among young women. The non-medical slang term refers to women who choose to eat less so they can party without gaining weight."

R. Andrew Chambers, MD, Assistant Professor, Institute of Psychiatric Research and Director, Laboratory for Translational Neuroscience of Dual Diagnosis Disorders notes that many celebrity blog sites report similar patterns of behavior among young actresses such as Lindsay Lohan and Paris Hilton, and that the condition could be mimicked within the entertainment industry and contemporary youth culture at large.

Due to the risks especially in adolescents, of cognitive impairments and possible irreversible brain damage associated with binge drinking, urgent action has been recommended. There is some evidence that interventions by employers such as, health and life-style checks, psychosocial skills training and peer referral, can reduce the level of binge drinking. In the US brief motivational interventions have shown some benefit in reducing future binge drinking.

Adolescents who misuse alcohol can benefit from interventions aimed at risk reduction. For more severe cases an intervention involving parents, guardians, and/or a psychotherapist is recommended. An effective strategy of intervention for adolescents whose binge drinking leads to admission to hospital, e.g. for alcohol poisoning or injury, is manualised brief interventions at the hospital in one to four counseling sessions each lasting 30 to 60 minutes conducted by trained staff. Evaluation of personal pattern of drinking and associated risks and an emphasis on personal responsibility in a non-condescending manner is recommended during the intervention; discussing and informing/educating the adolescent of possible negative short and long-term consequences of drinking is recommended. The setting of goals and rules to achieve those goals is also recommended during intervention with problem binge drinking adolescents.

Increasing public information and awareness regarding the risks of binge drinking, conducting interviews in emergency departments of young people suspected of harmful drinking patterns and trying to persuade them to accept individual counseling in youth addiction counseling services are effective strategies for reducing the harm of binge drinking. Encouraging recreational and adventurous training activities such as climbing or driving can be used alternative "natural buzzes" to alcohol misuse. Additionally the provision of educational content about the risks of binge drinking and a risk assessment are beneficial during intervention with young binge drinkers and a referral in the case of an alcohol use disorder for specialised help.

According to the NIAAA definition of "heavy drinkers", men may be at risk for alcohol-related problems if their alcohol consumption exceeds 14 standard drinks per week or 4 drinks per day, and women may be at risk if they have more than 7 standard drinks per week or 3 drinks per day. Despite this risk, a 2014 report in the National Survey on Drug Use and Health found that only 10% of either "heavy drinkers" or "binge drinkers" also met the criteria for alcohol dependence, while only 1.3% of non-binge drinkers met this criteria. An inference drawn in this study is that evidence-based policy strategies and clinical preventive services may effectively reduce binge drinking without requiring addiction treatment in most cases.

About 12% of American adults have had an alcohol dependence problem at some time in their life. In the UK the NHS estimates that around 9% of men and 4% of UK women show signs of alcohol dependence.

Pregaming (also pre-drinking or pre-loading) is the process of getting drunk prior to going out socializing, typically done by college students and young adults in the United States and Europe, in a manner as cost-efficient as possible, with hard liquor and cheap beer consumed while in small groups.

Although pregaming is typically done before a night out, it can also precede other activities, like attending a college football game, large party, social function, or another activity where possession of alcohol may be limited or prohibited. The name "pregaming" spread from the drinking that took place during tailgating before football games to encompass similar drinking periods.

Other terms for the practice are pre-partying, prinking and (in Europe) prefunking.

The relationship between alcohol and weight is the subject of inconclusive studies. Findings of these studies range from increase in body weight to a small decrease among women who begin consuming alcohol. Some of these studies are conducted with a large number of subjects; one involved nearly 80,000 and another 140,000 subjects.

Findings are inconclusive because alcohol itself contains 7 calories per gram, but research suggests that alcohol energy is not efficiently used. Alcohol also appears to increase metabolic rate significantly, thus causing more calories to be burned rather than stored in the body as fat (Klesges "et al.", 1994). Other research has found consumption of sugar to decrease as consumption of alcohol increases.

According to Dr. Kent Bunting, the research results do not necessarily mean that people who wish to lose weight should continue to consume alcohol because consumption is known to have an enhancing effect on appetite. Due to these discrepancies in findings, the relationship between alcohol and weight remains unresolved and requires further research.

Biological and environmental factors are thought to contribute to alcoholism and obesity. The physiologic commonalities between excessive eating and excessive alcohol drinking shed light on intervention strategies, such as pharmaceutical compounds that may help those who suffer from both.

Some of the brain signaling proteins that mediate excessive eating and weight gain also mediate uncontrolled alcohol consumption. Some physiological substrates that underlie food intake and alcohol intake have been identified. Melanocortins, a group of signaling proteins, are found to be involved in both excessive food intake and alcohol intake.

Alcohol may contribute to obesity. A study found frequent, light drinkers (three to seven drinking days per week, one drink per drinking day) had lower BMIs than infrequent, but heavier drinkers. Although calories in liquids containing ethanol may fail to trigger the physiologic mechanism that produces the feeling of fullness in the short term, long-term, frequent drinkers may compensate for energy derived from ethanol by eating less.

Alcohol dependence is not prerequisite to blackouts (either en bloc or fragmentary). Students in one study who reported blackouts were demographically similar to other drinking students. Importantly, however, students reporting blackouts drank more, and had other symptoms of alcoholic drinking, even though they did not fall into the alcoholic range on the Michigan Alcoholism Screening Test (MAST). Half of the students reported having had a blackout during their drinking careers, which closely followed other research findings.

In another study 25% of healthy college students reported being familiar with alcoholic blackouts. 51% of the students reported that they had had at least one blackout. Blackouts were reported during activities such as spending money (27%), sexual conduct (24%), fighting (16%), vandalism (16%), unprotected intercourse (6%), and driving a car (3%). So a significant number of students were engaged in a range of possibly hazardous activities during blackouts.

Of 545 individuals in another study, 161 (29.5%) reported driving drunk, 139 (25.5%) reported a regretted sexual situation, 67 (12.3%) reported unprotected sex, 60 (11%) reported having damaged property, 55 (10.1%) reported getting into a physical fight, and 29 (5.3%) reported injuring someone while under the influence of alcohol in the past 6 months.

Although the incidence of underage drinking is still significant, government, university and national statistics have confirmed that alcohol use and binge drinking among high school students has declined steadily over the past three decades, and continues to decline annually. According to a United States Substance Abuse and Mental Health Services Administration study involving 30,000 youths aged 12 to 20 years old, between 2002 and 2013 the percentage of underage drinkers declined from 28.8% to 22.7%. Underage binge drinkers decreased 19.3% to 14.2%. A December 2014 study performed by the University of Michigan also found that 75% of senior high school students disapproved of drinking excessively on the weekends. Alcohol still proved to be the favored substance of abuse among American youths however, with tobacco and illicit drugs following in rank.
