The Effects of Alcohol on Your Body

Alcohol abuse encompasses a spectrum of unhealthy alcohol drinking behaviors, ranging from binge drinking to alcohol dependence , in extreme cases resulting in health problems for individuals and large scale social problems such as alcohol-related crimes. Globally, alcohol consumption is the seventh leading risk factor for both death and the burden of disease and injury. In short, except for tobacco , alcohol accounts for a higher burden of disease than any other drug.

Alcohol use is a major cause of preventable liver disease worldwide, and alcoholic liver disease is the main alcohol-related chronic medical illness. Alcohol use disorder AUD reportedly most often affects young men aged 18—24 years of lower socioeconomic status. Risky drinking also called hazardous drinking is defined by drinking above the recommended limits:.

In the DSM-IV , alcohol abuse and alcohol dependence were defined as distinct disorders from to The DSM-5 combined those two disorders into alcohol use disorder with sub-classifications of severity. There is no " alcoholism " diagnosis in medical care. Alcohol misuse is a term used by United States Preventive Services Task Force to describe a spectrum of drinking behaviors that encompass risky drinking, alcohol abuse, and alcohol dependence similar meaning to alcohol use disorder but not a term used in DSM.

Individuals with an alcohol use disorder will often complain of difficulty with interpersonal relationships, problems at work or school, and legal problems. Additionally, people may complain of irritability and insomnia. However, while these findings are often present, they are not necessary to make a diagnosis of alcohol abuse.

Signs of alcohol abuse show its drastic effects on the central nervous system, including inebriation and poor judgment; chronic anxiety, irritability, and insomnia. Alcohol's effects on the liver include elevated liver function tests classically AST is at least twice as high as ALT. Prolonged use leads to cirrhosis and liver failure. With cirrhosis, patients develop an inability to process hormones and toxins.

The derangements of the endocrine system lead to the enlargement of the male breasts. The inability to process toxins leads to liver disease, such as hepatic encephalopathy.

Alcohol abuse can result in brain damage which causes impairments in executive functioning such as impairments to working memory and visuospatial function , and can cause an abnormal personality as well as affective disorders to develop.

Alcohol also causes impairment in a person's critical thinking. A person's ability to reason in stressful situations is compromised, and they seem very inattentive to what is going on around them. The prefrontal cortex is responsible for cognitive functions such as working memory , impulse control and decision making. This region of the brain is vulnerable to chronic alcohol-induced oxidative DNA damage.

A smaller volume of consumed alcohol has a greater impact on the older adult than it does on a younger individual. As a result, the American Geriatrics Society recommends for an older adult with no known risk factors less than one drink a day or fewer than two drinks per occasion regardless of gender.

Alcohol abuse is significantly associated with suicide and violence. Alcohol is the most significant health concern in Native American communities because of very high rates of alcohol dependence and abuse; up to 80 percent of suicides and 60 percent of violent acts are a result of alcohol abuse in Native American communities.

In the United States alcohol-related violence is related to more severe injuries and chronic cases. Alcohol abuse among pregnant women causes their baby to develop fetal alcohol syndrome. Fetal alcohol syndrome is the pattern of physical abnormalities and the impairment of mental development which is seen with increasing frequency among children with alcoholic mothers.

Surviving infants may suffer severe abnormalities such as abnormal eyes, fissures, lips and incomplete cerebella. Some infants may develop lung disease. It is even possible that the baby throughout pregnancy will develop heart defects such as ventricular septal defect or atrial septal defect.

However, other organizations advise complete abstinence from alcohol while pregnant. Adolescence and the onset of puberty have both a physiological and social impact on a developing person. About half of grade 12 students have been drunk, and a third binge drink. Its symptoms include troublesome behaviour in school, constantly lying, learning disabilities and social impairments. Alcohol abuse during adolescence greatly increases the risk of developing an alcohol use disorder in adulthood due to changes to neurocircuitry that alcohol abuse causes in the vulnerable adolescent brain.

Societal inequalities among other factors have influenced an adolescents decision to consume alcohol. Bogren, [32]. The cause of alcohol abuse is complex. Alcohol abuse is related to economic and biological origins and is associated with adverse health consequences. Another influencing factor among adolescents and college students are the perceptions of social norms for drinking; people will often drink more to keep up with their peers, as they believe their peers drink more than they actually do.

They might also expect to drink more given the context e. Alcohol abuse is also associated with acculturation, because social and cultural factors such as an ethnic group's norms and attitudes can influence alcohol abuse. A person misusing alcohol may be doing so because they find alcohol's effects provide relief from a psychological problem, such as anxiety or depression. Often both the alcohol misuse and psychological problems need to be treated at the same time.

The numbing effects of alcohol and narcotics can become a coping strategy for traumatized people who are unable to dissociate themselves from the trauma. However, the altered or intoxicated state of the abuser prevents the full consciousness necessary for healing. Gender differences may affect drinking patterns and the risk for developing alcohol use disorders.

Excessive alcohol use causes neuroinflammation and leads to myelin disruptions and white matter loss. The developing adolescent brain is at increased risk of brain damage and other long-lasting alterations to the brain. Until recently, the underlying mechanisms mediating the link between pubertal maturation and increased alcohol use in adolescence was poorly understood.

Now research has suggested that sex steroid hormone levels may play a role in this interaction. When controlling for age, it was demonstrated that elevated estradiol and testosterone levels in male teenagers undergoing pubertal development was linked to increased alcohol consumption.

The same associations with hormone levels were not demonstrated in females undergoing pubertal development. It is hypothesized that sex steroid hormones, such as testosterone and estradiol, are stimulating areas in the male brain that function to promote sensation-seeking and status-seeking behaviors and result in increased alcohol usage.

Additionally, the enzyme TTTan aromatase, which functions in the male brain to convert testosterone to estradiols, has been linked to addictive and reward-seeking behaviors. Therefore, the increased activity of the enzyme may be influencing male adolescent alcohol-usage behaviors during pubertal development. The brain goes through dynamic changes during adolescence as a result of advancing pubertal maturation, and alcohol can damage long- and short-term growth processes in teenagers. For its diagnosis, at least one of the following criteria had to be fulfilled in the last 12 months:.

The alcohol abuse diagnosis is no longer used in the DSM-5 released in , it is now part of the alcohol use disorder diagnosis. Of the four alcohol abuse criteria, all except the one referring to alcohol-related legal problems are included in the alcohol use disorder criteria. 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.

According to European law, individuals who are suffering from alcohol abuse or other related problems cannot be given a driver's 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, In many of these occasions the family members would try to help the individual to change or to help improve the individual's lifestyle.

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. The motivation required to achieve abstinence is dynamic; family, friends and health practitioners play a role in affecting this motivation.

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.

Alcohol abuse is said to be most common in people aged between 15 and 24 years, according to Moreira Causes of alcohol abuse are complex and are likely the combination of many factors, from coping with stress to childhood development.

Alcohol abuse during adolescence, especially early adolescence i. Alcohol use disorders often cause a wide range of cognitive impairments that result in significant impairment of the affected individual. If alcohol-induced neurotoxicity has occurred a period of abstinence for on average a year is required for the cognitive deficits of alcohol abuse to reverse. Occasional binge drinkers one or two times in past two weeks , were found to be four times more likely to be diagnosed with alcohol abuse or dependence compared to non-heavy episodic drinkers.

While the effects of alcohol can sometimes have a short term positive impact on our mood, in the long term it can cause problems for mental health. Drinking alcohol is linked to a range of mental health issues from depression and memory loss, to suicide. Regular, heavy drinking interferes with chemicals in the brain that are vital for good mental health. So while we might feel relaxed after a drink, in the long run alcohol has an impact on mental health and can contribute to feelings of depression and anxiety, and make stress harder to deal with. The brain relies on a delicate balance of chemicals and processes. Alcohol is a depressant, which means it can disrupt that balance, affecting our thoughts, feelings and actions — and sometimes our long-term mental health.

Он быстро подошел к ним и остановился в нескольких сантиметрах от дрожащего Чатрукьяна. - Вы что-то сказали. - Сэр, - задыхаясь проговорил Чатрукьян.  - ТРАНСТЕКСТ вышел из строя. - Коммандер, - вмешалась Сьюзан, - я хотела бы поговорить… Стратмор жестом заставил ее замолчать.

Размышляя об этом, Сьюзан вдруг вспомнила фразу, сказанную Стратмором: Я попытался запустить Следопыта самостоятельно, но информация, которую он выдал, оказалась бессмысленной. Сьюзан задумалась над этими словами. Информация, которую он выдал… Она резко подняла голову. Возможно ли. Информация, которую он выдал. Если Стратмор получил от Следопыта информацию, значит, тот работал. Она оказалась бессмысленной, потому что он ввел задание в неверной последовательности, но ведь Следопыт работал.

Вокруг него бушевала настоящая буря, но в его глазах она увидела смирение. Губы Стратмора приоткрылись, произнеся последнее в его жизни слово: Сьюзан. Воздух, ворвавшийся в ТРАНСТЕКСТ, воспламенился. В ослепительной вспышке света коммандер Тревор Стратмор из человека превратился сначала в едва различимый силуэт, а затем в легенду. Взрывной волной Сьюзан внесло в кабинет Стратмора, и последним, что ей запомнилось, был обжигающий жар.

 - Я в это не верю. Всем известно, что невзламываемый алгоритм - математическая бессмыслица. Хейл улыбнулся: - Ну конечно… Принцип Бергофского. - А также здравый смысл! - отрезала. - Кто знает… - Хейл театрально вздохнул.

 Пожалуйста, сядь, Сьюзан. У нее был совершенно растерянный вид. - Сядь, - повторил коммандер, на этот раз тверже. - Выпустите меня! - Она испуганно смотрела на открытую дверь его кабинета.

Губы Стратмора приоткрылись, произнеся последнее в его жизни слово: Сьюзан. Воздух, ворвавшийся в ТРАНСТЕКСТ, воспламенился. В ослепительной вспышке света коммандер Тревор Стратмор из человека превратился сначала в едва различимый силуэт, а затем в легенду.
