Long-term effects of alcohol#Cardiovascular system

{{Short description|Health effects of long-term alcohol consumption}}

The long-term effects of alcohol have been extensively researched. The health effects of long-term alcohol consumption vary depending on the amount consumed. Even light drinking poses health risks,{{cite web |title=No level of alcohol consumption is safe for our health |url=https://www.who.int/europe/news/item/04-01-2023-no-level-of-alcohol-consumption-is-safe-for-our-health |website=www.who.int |language=en}} but atypically small amounts of alcohol may have health benefits.{{cite journal |author1=GBD 2020 Alcohol Collaboration|title=Population-level risks of alcohol consumption by amount, geography, age, sex, and year: a systematic analysis for the Global Burden of Disease Study 2020 |journal=The Lancet |date=July 2022 |volume=400 |issue=10347 |pages=185–235 |doi=10.1016/S0140-6736(22)00847-9|pmid=35843246 |pmc=9289789 }} Alcoholism causes severe health consequences which outweigh any potential benefits.

Long-term alcohol consumption is capable of damaging nearly every organ and system in the body.{{cite book|editor1-first=Woody|editor1-last=Caan|editor2-first=Jackie de|editor2-last=Belleroche|title=Drink, Drugs and Dependence: From Science to Clinical Practice|url=https://archive.org/details/drinkdrugsdepende00caan|url-access=registration|edition=1st|date=11 April 2002 |publisher=Routledge |isbn=978-0-415-27891-1 |pages=[https://archive.org/details/drinkdrugsdepende00caan/page/19 19]–20}} Risks include malnutrition, cirrhosis, chronic pancreatitis, erectile dysfunction, hypertension, coronary heart disease, ischemic stroke, heart failure, atrial fibrillation, gastritis, stomach ulcers, alcoholic liver disease,{{cite journal|author=Cargiulo T|title=Understanding the health impact of alcohol dependence|journal=Am J Health Syst Pharm|volume=64|issue=5 Suppl 3|pages=S5–11|date=March 2007|pmid=17322182|doi=10.2146/ajhp060647}} certain types of dementia, and several types of cancer, including oropharyngeal cancer, esophageal cancer, liver cancer, colorectal cancer, and female breast cancers.{{cite web|url=https://www.scientificamerican.com/article/alcohol-consumption-increases-risk-of-breast-and-other-cancers-doctors-say/|title=Alcohol Consumption Increases Risk of Breast and Other Cancers, Doctors Say|author= Cheryl Platzman Weinstock|publisher=Scientific American|date=8 November 2017|access-date=13 November 2018|quote=In fact, alcohol consumption is known to increase the risk of several cancers, including head and neck, esophageal, liver, colorectal and female breast cancers.}} In addition, damage to the central nervous system and peripheral nervous system (e.g., painful peripheral neuropathy) can occur from chronic heavy alcohol consumption.{{cite journal|vauthors=Müller D, Koch RD, von Specht H, Völker W, Münch EM|title=Neurophysiologic findings in chronic alcohol abuse|language=de|journal=Psychiatr Neurol Med Psychol (Leipz)|volume=37|issue=3|pages=129–132|date=1985|pmid=2988001}}{{cite journal|author=Testino G|title=Alcoholic diseases in hepato-gastroenterology: a point of view |journal=Hepatogastroenterology |volume=55 |issue=82–83 |pages=371–377 |year=2008 |pmid=18613369}} There is also an increased risk for accidental injuries, for example, those sustained in traffic accidents and falls.

Conversely, light intake of alcohol may have some beneficial effects. The association of alcohol intake with reduced cardiovascular risk has been noted since 1904{{cite journal |author=Cabot, R.C. |title=The relation of alcohol to arteriosclerosis |journal=Journal of the American Medical Association |year=1904 |volume=43 |issue=12 |pages=774–775|doi=10.1001/jama.1904.92500120002a |url=https://zenodo.org/record/1447273 }} and remains even after adjusting for known confounders. Light alcohol intake is also associated with reduced risk of type 2 diabetes, gastritis, and cholelithiasis.{{cite journal|vauthors=Taylor B, Rehm J, Gmel G |title=Moderate alcohol consumption and the gastrointestinal tract |journal=Dig Dis |volume=23 |issue=3–4 |pages=170–176 |year=2005 |pmid=16508280 |doi=10.1159/000090163|s2cid=30141003 }} However, these are only observational studies and high-quality evidence for the beneficial effects of alcohol is nonexistent.{{Cite journal |last=Fekjær |first=Hans Olav |date=December 2013 |title=Alcohol—a universal preventive agent?

The developing adolescent brain is particularly vulnerable to the toxic effects of alcohol.{{cite journal |vauthors=Guerri C, Pascual MA |year=2010 |title=Mechanisms involved in the neurotoxic, cognitive, and neurobehavioral effects of alcohol consumption during adolescence |journal=Alcohol |volume=44 |issue=1 |pages=15–26 |doi=10.1016/j.alcohol.2009.10.003 |pmid=20113871}} In addition, the developing fetal brain is also vulnerable, and fetal alcohol spectrum disorders (FASDs) may result if pregnant mothers consume alcohol. Some nations have introduced alcohol packaging warning messages that inform consumers about alcohol and cancer, and about risk of fetal alcohol syndrome for women who drink while pregnant.{{cite news |date=26 September 2018 |title=Cancer warning labels to be included on alcohol in Ireland, minister confirms |url=https://www.belfasttelegraph.co.uk/news/republic-of-ireland/cancer-warning-labels-to-be-included-on-alcohol-in-ireland-minister-confirms-37357231.html |newspaper=Belfasttelegraph.co.uk |publisher=Belfast Telegraph |language=en}}

Alcohol does have psychosocial benefits such as stress reduction, mood elevation, increased sociability, and relaxation, but it is unclear if these outweigh the confirmed increase in the risk of cancer.

The level of ethanol consumption that minimizes the risk of disease, injury, and death is subject to some controversy.{{cite journal |last1=Tsai |first1=MK |last2=Gao |first2=W |last3=Wen |first3=CP |title=The relationship between alcohol consumption and health: J-shaped or less is more? |journal=BMC Medicine |date=3 July 2023 |volume=21 |issue=1 |pages=228 |doi=10.1186/s12916-023-02911-w |pmid=37400823 |pmc=10318728 |doi-access=free }} Several studies have found a J-shaped relationship between alcohol consumption and health,{{Cite journal|last1=Di Castelnuovo|first1=A.|last2=Costanzo|first2=S.|last3=Bagnardi|first3=V.|last4=Donati|first4=MB.|last5=Iacoviello|first5=L.|last6=de Gaetano|first6=G.|title=Alcohol dosing and total mortality in men and women: an updated meta-analysis of 34 prospective studies|journal=Arch Intern Med|volume=166|issue=22|pages=2437–45|doi=10.1001/archinte.166.22.2437|pmid=17159008|year=2006}}{{cite journal |vauthors=Stockwell T, Zhao J, Panwar S, Roemer A, Naimi T, Chikritzhs T |title=Do "Moderate" Drinkers Have Reduced Mortality Risk?

In 2013, Norwegian psychiatrist Hans Olav Fekjær compared the situation to those of hormone replacement therapy (HRT), vitamin E, and β-carotene; similarly to alcohol, observational studies for each of these treatments showed significantly reduced risk of coronary heart disease, but initial randomized trials of these treatments failed to replicate the effect. For HRT, pooling multiple randomized control trials and stratifying the data by age and time since menopause showed the benefits were limited to treatment soon after menopause.{{cite journal |last1=El Khoudary |first1=Samar R. |last2=Aggarwal |first2=Brooke |last3=Beckie |first3=Theresa M. |last4=Hodis |first4=Howard N. |last5=Johnson |first5=Amber E. |last6=Langer |first6=Robert D. |last7=Limacher |first7=Marian C. |last8=Manson |first8=JoAnn E. |last9=Stefanick |first9=Marcia L. |last10=Allison |first10=Matthew A. |title=Menopause Transition and Cardiovascular Disease Risk: Implications for Timing of Early Prevention: A Scientific Statement From the American Heart Association |journal=Circulation |date=22 December 2020 |volume=142 |issue=25 |pages=e506–e532 |doi=10.1161/CIR.0000000000000912|doi-access=free |pmid=33251828 }} For vitamin E, trials have shown that the benefits are limited to certain populations such as those with diabetes and a specific genotype.{{cite journal |last1=Vardi |first1=Moshe |last2=Levy |first2=Nina S. |last3=Levy |first3=Andrew P. |title=Vitamin E in the prevention of cardiovascular disease: the importance of proper patient selection |journal=Journal of Lipid Research |date=September 2013 |volume=54 |issue=9 |pages=2307–2314 |doi=10.1194/jlr.R026641|doi-access=free |pmid=23505320 |pmc=3735930 }} For β-carotene, the randomized trials have shown that β-carotene increases cardiovascular disease risk when supplemented, with all beneficial effects due to other vitamins in foods providing β-carotene.{{cite journal |last1=Yang |first1=Jiaqi |last2=Zhang |first2=Yulin |last3=Na |first3=Xiaona |last4=Zhao |first4=Ai |title=β-Carotene Supplementation and Risk of Cardiovascular Disease: A Systematic Review and Meta-Analysis of Randomized Controlled Trials |journal=Nutrients |date=18 March 2022 |volume=14 |issue=6 |pages=1284 |doi=10.3390/nu14061284|doi-access=free |pmid=35334942 |pmc=8950884 }}

In light of the conflicting evidence, many have cautioned against recommendations for the use of alcohol for health benefits.

The available evidence is in agreement that current drinking levels are too high. The WHO has emphasized the need to revise alcohol control policies worldwide in order to reduce overall alcohol consumption.

Globally, assuming the J-shaped curve is correct, the age-standardised, both-sexes consumption that minimizes risk is about 5 grams of ethanol per day, and an average individual would cause themselves harm by drinking more than 17 grams per day. However, the average intake among current drinkers in 2016 was approximately 40 grams of ethanol per day.{{efn|Calculated as {{math|(1.5*1.7/0.39+0.9*0.87/0.25)/(1.5+0.9)}}, with figures from {{harvtxt|GBD 2016 Alcohol Collaboration|2018}}. See also [https://www.who.int/data/gho/data/indicators/indicator-details/GHO/alcohol-average-daily-intake-in-grams-among-drinkers-with-95-ci WHO figures by country]}} 1.03 billion males (35.1% of the male population aged ≥15 years, ~2/3 of male drinkers) and 312 million females (10.5% of the female population aged ≥15 years, ~1/3 of female drinkers) consumed harmful amounts of alcohol.{{efn|The fraction of current drinkers is estimated using [https://databank.worldbank.org/source/population-estimates-and-projections/preview/on WorldBank 2016 population numbers] and combining the GBD 2016 and GBD 2020 analyses based on the statement that "Since 1990, the global proportion of drinkers consuming alcohol in excess of the NDE has not changed significantly." For example, GBD 2016 states there were 1.5 billion male current drinkers in 2016, WorldBank states there were 3,770,341,364 males and 1,018,695,045 males under 15, and we can assume based on GBD 2020 that 35.1% of males 15+ were drinking harmful amounts, so we calculate {{math|1= .351*(3770341364-1018695045)/1.5e9≈2/3}}}} The proportion of the population consuming harmful amounts of alcohol has stayed at approximately the same level over the past three decades.

Estimates of the worldwide number of deaths per year caused by alcohol vary. The 2016 Global Burden of Disease (GBD) study estimated 2.8 million, while the 2020 GBD study estimated 1.78 million. The WHO estimates 3 million deaths per year from harmful use of alcohol, representing 5.3% of all deaths across the globe. All of these numbers are net deaths, subtracting deaths prevented from deaths caused. Professor Tim Stockwell, former director of the Canadian Institute for Substance Use Research argues that alcohol may not prevent any deaths and guesses that as many as 6 million deaths may be caused by alcohol.{{cite web |last1=Stockwell |first1=Tim |title=How Several Hundred Lancet Co-Authors Lost a Million Global Alcohol-Caused Deaths |url=https://movendi.ngo/blog/2022/08/04/how-several-hundred-lancet-co-authors-lost-a-million-global-alcohol-caused-deaths/ |website=Movendi International |date=4 August 2022}} Besides this, the WHO attributes 5.1% of the global burden of disease and injury to alcohol, as measured in disability-adjusted life years (DALYs).{{Cite web |title=Alcohol |url=https://www.who.int/news-room/fact-sheets/detail/alcohol |access-date=2024-03-18 |website=www.who.int |language=en}} The WHO does not list alcohol in its 2019 list of the top 20 leading causes of DALYs, but alcohol use disorder (AUD) would rank around #39, combining AUD with alcohol-related cirrhosis and liver cancer would rank between malaria (#19) and refractive errors (#20), and all alcohol-attributed DALYs would rank between stroke (#3) and lower respiratory infections (#4).{{cite web |title=Global health estimates 2020: Leading causes of DALYs |url=https://www.who.int/data/gho/data/themes/mortality-and-global-health-estimates/global-health-estimates-leading-causes-of-dalys |website=World Health Organization|date=2020 |language=en}} Similarly the number of alcohol-attributed deaths would rank between chronic obstructive pulmonary disease (#3) and lower respiratory infections (#4).{{cite web |title=Global health estimates 2020: Leading causes of death |url=https://www.who.int/data/gho/data/themes/mortality-and-global-health-estimates/ghe-leading-causes-of-death |website=World Health Organization|date=2020 |language=en}}

The risks of alcohol consumption are age-dependent. Risk is greatest among males aged 15–39 years, due to binge drinking which may result in violence or traffic accidents. It is less risky and potentially more beneficial for an older individual to consume a given amount of alcohol, compared to a similar younger individual, as they are less likely to develop cancer during their remaining lifespan, less likely to be involved in accidents, and more likely to benefit from alcohol's cardiovascular effects. Taking the lower bound of the confidence intervals, the GBD 2020 study suggests that people do not need to drink until age 25, and in many regions, the study did not find any significant benefit for drinking over abstinence even as late as ages 45 or 60. Other studies have found similar patterns.{{cite journal |last1=White |first1=Ian R. |last2=Altmann |first2=Dan R. |last3=Nanchahal |first3=Kiran |title=Alcohol consumption and mortality: modelling risks for men and women at different ages |journal=BMJ |date=27 July 2002 |volume=325 |issue=7357 |pages=191 |doi=10.1136/bmj.325.7357.191|pmid=12142306 |pmc=117446 }}

A study of 4,465 subjects in India confirmed the association of alcohol consumption with coronary risk in men. Compared to lifetime abstainers, alcohol users had higher blood sugar (2 mg/dl), blood pressure (2 mm Hg) levels, and the high-density lipoprotein cholesterol (HDL-C) levels (2 mg/dl) and significantly higher tobacco use (63% vs. 21%).

{{Main|Alcohol-related brain damage|Long-term impact of alcohol on the brain}}

Alcohol misuse is associated with widespread and significant brain lesions. Alcohol related brain damage is not only due to the direct toxic effects of alcohol; alcohol withdrawal, nutritional deficiency, electrolyte disturbances, and liver damage are also believed to contribute to alcohol-related brain damage.{{Cite journal|doi=10.1111/j.1530-0277.1998.tb04389.x|last1=Neiman|first1=J.|title=Alcohol as a risk factor for brain damage: neurologic aspects|journal=Alcohol Clin Exp Res|volume=22|issue=7 Suppl|pages=346S–351S|date=Oct 1998|pmid=9799959}}

Alcohol can cause brain damage, Wernicke's encephalopathy and Alcoholic Korsakoff syndrome which frequently occur simultaneously, known as Wernicke–Korsakoff syndrome.{{cite journal | vauthors = Arts NJ, Walvoort SJ, Kessels RP | title = Korsakoff's syndrome: a critical review | journal = Neuropsychiatric Disease and Treatment | volume = 13 | pages = 2875–2890 | date = 2017-11-27 | pmid = 29225466 | pmc = 5708199 | doi = 10.2147/NDT.S130078 | doi-access = free }} Lesions, or brain abnormalities, are typically located in the diencephalon which result in anterograde and retrograde amnesia, or memory loss.

=Cognition and dementia=

Excessive alcohol intake is associated with impaired prospective memory. This impaired cognitive ability leads to increased failure to carry out an intended task at a later date, for example, forgetting to lock the door or to post a letter on time. The higher the volume of alcohol consumed and the longer consumed, the more severe the impairments.{{Cite journal|doi=10.2174/1874473710801010036|last1=Heffernan|first1=TM|title=The impact of excessive alcohol use on prospective memory: a brief review.|journal=Curr Drug Abuse Rev|volume=1|issue=1|pages=36–41|date=2008|pmid=19630703}} One of the organs most sensitive to the toxic effects of chronic alcohol consumption is the brain.

{{main|Alcohol use and sleep}}

Chronic use of alcohol used to induce sleep can lead to insomnia: frequent moving between sleep stages occurs, with awakenings due to headaches and diaphoresis. Stopping chronic alcohol misuse can also lead to profound disturbances of sleep with vivid dreams. Chronic alcohol misuse is associated with NREM stage 3 and 4 sleep as well as suppression of REM sleep and REM sleep fragmentation. During withdrawal REM sleep is typically exaggerated as part of a rebound effect.{{Cite book|last1=Lee-chiong|first1=Teofilo|title=Sleep Medicine: Essentials and Review|date=24 April 2008|publisher=Oxford University Press, USA|url=https://books.google.com/books?id=s1F_DEbRNMcC&pg=PT105|isbn=978-0-19-530659-0|page=105}}

Alcohol-related psychosis may manifest itself through a kindling mechanism. The mechanism of alcohol-related psychosis is due to distortions to neuronal membranes, gene expression, as well as thiamin deficiency. It is possible in some cases that excessive alcohol use, via a kindling mechanism, can cause the development of a chronic substance-induced psychotic disorder, i.e. schizophrenia. The effects of an alcohol-related psychosis include an increased risk of depression and suicide as well as psychosocial impairments. However, moderate wine drinking has been shown to lower the risk for depression.{{cite web|url=https://www.sciencedaily.com/releases/2013/08/130829214354.htm |title=A wine a day ... keeps the psychiatrist away?

While alcohol initially helps social phobia or panic symptoms, with longer term alcohol misuse can often worsen social phobia symptoms and can cause panic disorder to develop or worsen, during alcohol intoxication and especially during the alcohol withdrawal syndrome. This effect is not unique to alcohol but can also occur with long-term use of drugs which have a similar mechanism of action to alcohol such as the benzodiazepines, which are sometimes prescribed as tranquilizers to people with alcohol problems.{{cite journal |vauthors=Terra MB, Figueira I, Barros HM |title=Impact of alcohol intoxication and withdrawal syndrome on social phobia and panic disorder in alcoholic inpatients |journal=Rev Hosp Clin Fac Med Sao Paulo |volume=59 |issue=4 |pages=187–92 |date=August 2004 |pmid=15361983 |doi=10.1590/S0041-87812004000400006|doi-access=free }} Approximately half of patients attending mental health services for conditions including anxiety disorders such as panic disorder or social phobia have alcohol or benzodiazepine dependence.

Addiction to alcohol, as with any addictive substance tested so far, has been correlated with an enduring reduction in the expression of GLT1 (EAAT2) in the nucleus accumbens and is implicated in the drug-seeking behavior expressed nearly universally across all documented addiction syndromes. This long-term dysregulation of glutamate transmission is associated with an increase in vulnerability to both relapse-events after re-exposure to drug-use triggers as well as an overall increase in the likelihood of developing addiction to other reinforcing drugs. Drugs which help to re-stabilize the glutamate system such as N-acetylcysteine have been proposed for the treatment of addiction to cocaine, nicotine, and alcohol.{{cite journal | vauthors = McClure EA, Gipson CD, Malcolm RJ, Kalivas PW, Gray KM | title = Potential role of N-acetylcysteine in the management of substance use disorders | journal = CNS Drugs | volume = 28 | issue = 2 | pages = 95–106 | year = 2014 | pmid = 24442756 | pmc = 4009342 | doi = 10.1007/s40263-014-0142-x }}

The effect on depression and returning to drinking among individuals with alcohol dependence has always been controversial. Studies show that after doing a study on men and women hospitalized for alcohol dependence the likelihood of returning to drinking with depression is extremely high. A diagnosis of major depression at entry into an inpatient treatment for alcohol dependence showed shorter times to first drink and also relapse in both women and men.{{Cite journal |last1=Greenfield |first1=Shelly F. |last2=Weiss |first2=Roger D. |last3=Muenz |first3=Larry R. |last4=Vagge |first4=Lisa M. |last5=Kelly |first5=John F. |last6=Bello |first6=Lisa R. |last7=Michael |first7=Jacqueline |date=1998-03-01 |title=The Effect of Depression on Return to Drinking: A Prospective Study |url=https://doi.org/10.1001/archpsyc.55.3.259 |journal=Archives of General Psychiatry |volume=55 |issue=3 |pages=259–265 |doi=10.1001/archpsyc.55.3.259 |pmid=9510220 |issn=0003-990X}}

=Gallbladder effects=

Research has found that drinking reduces the risk of developing gallstones. Compared with alcohol abstainers, the relative risk of gallstone disease, controlling for age, sex, education, smoking, and body mass index, is 0.83 for occasional and regular moderate drinkers (< 25 ml of ethanol per day), 0.67 for intermediate drinkers (25-50 ml per day), and 0.58 for heavy drinkers.

"An increase in frequency of alcohol consumption also was related to decreased risk. Combining the reports of quantity and frequency of alcohol intake, a consumption pattern that reflected frequent intake (5–7 days/week) of any given amount of alcohol was associated with a decreased risk, as compared with nondrinkers.

=Liver disease=

{{Main|Alcoholic liver disease|Cirrhosis|Hepatotoxin|Alcoholic hepatitis|Fatty liver disease}}

During the metabolism of alcohol via the respective dehydrogenases, nicotinamide adenine dinucleotide (NAD) is converted into reduced NAD. Normally, NAD is used to metabolize fats in the liver, and as such alcohol competes with these fats for the use of NAD. Prolonged exposure to alcohol means that fats accumulate in the liver, leading to the term 'fatty liver'. Continued consumption (such as in alcohol use disorder) then leads to cell death in the hepatocytes as the fat stores reduce the function of the cell to the point of death. These cells are then replaced with scar tissue, leading to the condition called cirrhosis.

Alcoholic liver disease is a major public health problem. For example, in the United States up to two million people have alcohol-related liver disorders. Chronic heavy alcohol consumption can cause fatty liver, cirrhosis, and alcoholic hepatitis. Treatment options are limited and consist of most importantly discontinuing alcohol consumption. In cases of severe liver disease, the only treatment option may be a liver transplant from alcohol abstinent donors. Research is being conducted into the effectiveness of anti-TNFs. Certain complementary medications, e.g., milk thistle and silymarin, appear to offer some benefit.{{cite journal|vauthors=Barve A, Khan R, Marsano L, Ravindra KV, McClain C |title=Treatment of alcoholic liver disease|journal=Ann Hepatol|volume=7|issue=1|pages=5–15|year=2008|pmid=18376362|url=http://www.stopdrinkingexpert.com/pdf/ijms.pdf|doi=10.1016/S1665-2681(19)31883-6}}{{cite journal|vauthors=Fehér J, Lengyel G |title=Silymarin in the treatment of chronic liver diseases: past and future|language=hu|journal=Orv Hetil|volume=149|issue=51|pages=2413–8|date=December 2008|pmid=19073452|doi=10.1556/OH.2008.28519}} Alcohol is a leading cause of liver cancer in the Western world, accounting for 32-45% of hepatic cancers.

Oral and dental implications

= Oral cancer =

The consumption of alcohol alone is not associated with an increased risk of oral squamous cell carcinoma (OSCC); however, the synergistic consumption of alcohol and tobacco is positively associated with the occurrence of (OSCC), and significantly increases an individual's risk. Studies confirm that alcohol dissolves the lipid component of epithelium and increases the permeability, amplifying the toxicity of carcinogenic components of tobacco. Limiting the overall consumption of the two has shown to reduce the risk of OSCC by three-fourth. The knowledge provided is useful for better understanding the differences in the effect of the combined consumption of alcohol and tobacco, in the development of OSCC.{{Cite journal |last1=Mello |first1=Fernanda Weber |last2=Melo |first2=Gilberto |last3=Pasetto |first3=Júlia Jacoby |last4=Silva |first4=Carolina Amália Barcellos |last5=Warnakulasuriya |first5=Saman |last6=Rivero |first6=Elena Riet Correa |date=July 2019 |title=The synergistic effect of tobacco and alcohol consumption on oral squamous cell carcinoma: a systematic review and meta-analysis |url=http://link.springer.com/10.1007/s00784-019-02958-1 |journal=Clinical Oral Investigations |language=en |volume=23 |issue=7 |pages=2849–2859 |doi=10.1007/s00784-019-02958-1 |pmid=31111280 |s2cid=159040972 |issn=1432-6981}}

Alcohol consumption has frequently been associated with an increased risk of oral cancer in current literature. Studies have found that people that consume alcohol were two times more likely to develop oral cancer in comparison to people who did not. The mechanisms in which alcohol acts as a carcinogen within the oral cavity are currently not fully understood. It is thought to be a multifactorial disease which then gives rise to a cancerous lesion. Many theories have become apparent in research, including alcohol being responsible for high estrogen and androgen levels, specifically in women, which may facilitate the alcohol-related immunodeficiency and/or immunosuppression that causes carcinogenesis. Therefore, immediate cessation of the habit of alcohol consumption can aid in decreasing the risk of oral cancer.{{Cite journal |last1=Singhavi |first1=Hitesh Rajendra |last2=Singh |first2=Arjun |last3=Bhattacharjee |first3=Atanu |last4=Talole |first4=Sanjay |last5=Dikshit |first5=Rajesh |last6=Chaturvedi |first6=Pankaj |date=April 2020 |title=Alcohol and cancer risk: A systematic review and meta-analysis of prospective Indian studies |journal=Indian Journal of Public Health |volume=64 |issue=2 |pages=186–190 |doi=10.4103/ijph.IJPH_529_19 |issn=0019-557X |pmid=32584303 |doi-access=free }}

Alcohol-based mouthwashes used to be very common and can still be purchased for use today. Correlation in the presence of alcohol in mouthwashes with development of oral and pharyngeal cancer is unknown due to lack of evidence. However, it has been suggested that acetaldehyde, the first metabolite of ethanol, plays a role in the carcinogenesis of alcohol in oral cancer. Acetaldehyde, has been found to increase when in the salivary medium after an alcoholic beverage has been consumed and could possibly occur with alcohol-based mouthwashes as well, posing as a possible risk factor for oral cancer. However, more research must be conducted regarding these theories.{{Cite journal |last1=Ustrell-Borràs |first1=M. |last2=Traboulsi-Garet |first2=B. |last3=Gay-Escoda |first3=C. |date=2020-01-01 |title=Alcohol-based mouthwash as a risk factor of oral cancer: A systematic review |journal=Medicina Oral, Patologia Oral y Cirugia Bucal |volume=25 |issue=1 |pages=e1–e12 |doi=10.4317/medoral.23085 |issn=1698-6946 |pmc=6982979 |pmid=31655832}}

Alcohol consumption is associated with a higher risk of periodontitis, an inflammatory disease of the gums around the teeth. There was also found to be a dose-response relationship in which the risk of periodontitis increased by 0.4% for each additional gram of daily alcohol consumption. Mechanisms explaining the relationship between the two are still unclear; however, several explanations have been suggested. One explanation is the weakening of neutrophil activity by alcohol consumption which potentially leads to bacterial overgrowth and increases bacterial penetration subsequently leading to periodontal inflammation and periodontal disease. Characteristics of the disease include shrinkage of gingival height and increased mobility of teeth which may exfoliate if the disease continues to progress. A patient's consumption of alcohol needs to be monitored to estimate the risk of periodontitis, but further well-designed cohort studies are needed to reaffirm theses results.{{Cite journal |last1=Wang |first1=Jiantao |last2=Lv |first2=Jian |last3=Wang |first3=Wanchun |last4=Jiang |first4=Xiubo |date=July 2016 |title=Alcohol consumption and risk of periodontitis: a meta-analysis |url=https://pubmed.ncbi.nlm.nih.gov/27029013 |journal=Journal of Clinical Periodontology |volume=43 |issue=7 |pages=572–583 |doi=10.1111/jcpe.12556 |issn=1600-051X |pmid=27029013}}

{{Main|Alcohol and cortisol}}

Alcohol and cortisol have a complex relationship. While cortisol is a stress hormone, alcoholism can lead to increased cortisol levels in the body over time. This can be problematic because cortisol can temporarily shut down other bodily functions, potentially causing physical damage.

=Diabetes mellitus=

A meta-analysis determined the dose-response relationships by sex and end point using lifetime abstainers as the reference group. A U-shaped relationship was found for both sexes. Compared with lifetime abstainers, the relative risk (RR) for type 2 diabetes among men was most protective when consuming 22 g/day alcohol and became deleterious at just over 60 g/day alcohol. Among women, consumption of 24 g/day alcohol was most protective, and became deleterious at about 50 g/day alcohol.{{citation needed|date=April 2019}} A systematic review on intervention studies in women also supported this finding. It reported that alcohol consumption in moderation improved insulin sensitivity among women.{{cite journal |vauthors=Schrieks IC, Heil AL, Hendriks HF, Mukamal KJ, Beulens JW |title=The effect of alcohol consumption on insulin sensitivity and glycemic status: a systematic review and meta-analysis of intervention studies |journal=Diabetes Care |volume=38 |issue=4 |pages=723–732 |date=2015 |pmid=25805864 |doi=10.2337/dc14-1556 |s2cid=32005728 |doi-access=free }}

Effects of alcoholism on family and children

Children raised in alcoholic families have the potential to suffer emotional distress as they move into their own committed relationships. These children are at a higher risk for divorce and separation, unstable marital conditions and fractured families.{{cite journal|last1=Kearns-Bodkin|first1=Jill N.|last2=Leonard|first2=Kenneth E.|title=Relationship Functioning Among Adult Children of Alcoholics|journal=Journal of Studies on Alcohol and Drugs|pages=941–950|date=November 2008|pmc=2583382|pmid=18925353|volume=69|issue=6|doi=10.15288/jsad.2008.69.941}} Feelings of depression and antisocial behaviors experienced in early childhood frequently contribute to marital conflict and domestic violence.

Children of alcoholics often incorporate behaviors learned as children into their marital relationships. These behaviors lead to poor parenting practices. For example, adult children of alcoholics may simultaneously express love and rejection toward a child or spouse. This is known as insecure attachment. Insecure attachment contributes to trust and bonding issues with intimate partners and offspring. In addition, prior parental emotional unavailability contributes to poor conflict resolution skills in adult relationships. Evidence shows a correlation between alcoholic fathers who display harsh and ineffective parenting practices with adolescent and adult alcohol dependence.

Children of alcoholics are often unable to trust other adults due to fear of abandonment. Further, because children learn their bonding behaviors from watching their parents' interactions, daughters of alcoholic fathers may be unable to interact appropriately with men when they reach adulthood. Poor behavior modeling by alcoholic parents contributes to inadequate understanding of how to engage in opposite gender interactions.

Sons of alcoholics are at risk for poor self-regulation that is often displayed in the preschool years. This leads to blaming others for behavioral problems and difficulties with impulse control. Poor decision-making correlates to early alcohol use, especially in sons of alcoholics. Sons often demonstrate thrill-seeking behavior, harm avoidance, and exhibit a low level of frustration tolerance.

Economic impact from long-term consumption of alcohol

There is currently no consistent approach to measuring the economic impact of alcohol consumption.{{Cite journal|last1=Verhaeghe|first1=Nick|last2=Lievens|first2=Delfine|last3=Annemans|first3=Lieven|last4=Vander Laenen|first4=Freya|last5=Putman|first5=Koen|date=2017-01-18|title=Methodological Considerations in Social Cost Studies of Addictive Substances: A Systematic Literature Review|journal=Frontiers in Public Health|volume=4|pages=295|doi=10.3389/fpubh.2016.00295|issn=2296-2565|pmc=5241275|pmid=28149834|doi-access=free}} The economic burden such as direct, indirect, and intangible cost of diseases can be estimated through cost-of-illness studies.{{Cite journal|last=Rice|first=Dorothy P.|date=2000-09-01|title=Cost of illness studies: what is good about them?|url= |journal=Injury Prevention|language=en|volume=6|issue=3|pages=177–179|doi=10.1136/ip.6.3.177|issn=1353-8047|pmid=11003181|pmc=1730654}} Direct costs are estimated through prevalence and incidence studies, while indirect costs are estimated through the human capital method, the demographic method, and the friction cost method. However, it is difficult to accurately measure the economic impact due to differences in methodologies, cost items related to alcohol consumption, and measurement techniques.

Alcohol dependence has a far reaching impact on health outcomes. A study conducted in Germany in 2016 found the economic burden for those dependent on alcohol was 50% higher than those who were not.{{Cite journal|last1=Manthey|first1=Jakob|last2=Laramée|first2=Philippe|last3=Parrott|first3=Steve|last4=Rehm|first4=Jürgen|date=2016-08-31|title=Economic burden associated with alcohol dependence in a German primary care sample: a bottom-up study|journal=BMC Public Health|volume=16|issue=1 |pages=906|doi=10.1186/s12889-016-3578-8|pmid=27576562|pmc=5006576|issn=1471-2458 |doi-access=free }} In the study, over half of the economic cost was due to lost productivity, and only 6% was due to alcohol treatment programs. The economic cost was mostly borne by individuals between 30 and 49 years old. In another study conducted with data from eight European countries,{{Cite journal|last1=Odlaug|first1=B.L.|last2=Gual|first2=A.|last3=DeCourcy|first3=J.|last4=Perry|first4=R.|last5=Pike|first5=J.|last6=Heron|first6=L.|last7=Rehm|first7=J.|date=2016-03-01|title=Alcohol Dependence, Co-occurring Conditions and Attributable Burden|journal=Alcohol and Alcoholism|language=en|volume=51|issue=2|pages=201–209|doi=10.1093/alcalc/agv088|pmid=26246514|issn=0735-0414|pmc=4755551}} 77% of alcohol dependent patients had psychiatric and somatic co-morbidity, which in turn increased systematic healthcare and economic cost. Alcohol consumption can also affect the immune system and produce complications in people with HIV, pneumonia, and tuberculosis.{{Cite journal|last=Rehm|first=Jürgen|date=2011|title=The Risks Associated With Alcohol Use and Alcoholism|journal=Alcohol Research & Health|volume=34|issue=2|pages=135–143|issn=1535-7414|pmc=3307043|pmid=22330211}}

Indirect costs due to alcohol dependence are significant. The biggest indirect cost comes from lost productivity, followed by premature mortality.{{Cite journal|last1=Bouchery|first1=Ellen E.|last2=Harwood|first2=Henrick J.|last3=Sacks|first3=Jeffrey J.|last4=Simon|first4=Carol J.|last5=Brewer|first5=Robert D.|date=2011-11-01|title=Economic Costs of Excessive Alcohol Consumption in the U.S., 2006|url=http://www.ajpmonline.org/article/S0749-3797(11)00538-1/fulltext|journal=American Journal of Preventive Medicine|language=en|volume=41|issue=5|pages=516–524|doi=10.1016/j.amepre.2011.06.045|pmid=22011424|issn=0749-3797|citeseerx=10.1.1.460.5582}} Men with alcohol dependence in the U.S. have lower labor force participation by 2.5%, lower earnings by 5.0%, and higher absenteeism by 0.5–1.2 days. Female binge drinkers have higher absenteeism by 0.4–0.9 days. Premature mortality is another large contributor to indirect costs of alcohol dependence.{{Cite journal|last1=Rehm|first1=Jürgen|last2=Mathers|first2=Colin|last3=Popova|first3=Svetlana|last4=Thavorncharoensap|first4=Montarat|last5=Teerawattananon|first5=Yot|last6=Patra|first6=Jayadeep|date=2009-06-27|title=Global burden of disease and injury and economic cost attributable to alcohol use and alcohol-use disorders|journal=Lancet|volume=373|issue=9682|pages=2223–2233|doi=10.1016/S0140-6736(09)60746-7|issn=1474-547X|pmid=19560604|s2cid=27947246}} In 2004, 3.8% of global deaths were attributable to alcohol (6.3% for men and 1.1% for women). Those under 60 years old have much higher prevalence in global deaths attributable to alcohol at 5.3%.

In general, indirect costs such as premature mortality due to alcohol dependence, loss of productivity due to absenteeism and presenteeism, and cost of property damage and enforcement, far exceed the direct health care and law enforcement costs.{{Cite journal|last1=Thavorncharoensap|first1=Montarat|last2=Teerawattananon|first2=Yot|last3=Yothasamut|first3=Jomkwan|last4=Lertpitakpong|first4=Chanida|last5=Thitiboonsuwan|first5=Khannika|last6=Neramitpitagkul|first6=Prapag|last7=Chaikledkaew|first7=Usa|date=2010-06-09|title=The economic costs of alcohol consumption in Thailand, 2006|journal=BMC Public Health|volume=10|pages=323|doi=10.1186/1471-2458-10-323|pmid=20534112|pmc=2896941|issn=1471-2458 |doi-access=free }} Aggregating the economic cost from all sources, the impact can range from 0.45 to 5.44% of a country's gross domestic product (GDP).{{Cite journal|last1=Thavorncharoensap|first1=Montarat|last2=Teerawattananon|first2=Yot|last3=Yothasamut|first3=Jomkwan|last4=Lertpitakpong|first4=Chanida|last5=Chaikledkaew|first5=Usa|date=2009-11-25|title=The economic impact of alcohol consumption: a systematic review|journal=Substance Abuse Treatment, Prevention, and Policy|volume=4|pages=20|doi=10.1186/1747-597X-4-20|pmid=19939238|pmc=2791094|issn=1747-597X |doi-access=free }} The wide range is due to inconsistency in measurement of economic burden, as researchers in some studies attributed possible positive effects from long term alcohol consumption.{{Cite journal|last1=Jarl|first1=Johan|last2=Johansson|first2=Pia|last3=Eriksson|first3=Antonina|last4=Eriksson|first4=Mimmi|last5=Gerdtham|first5=Ulf-G.|last6=Hemström|first6=Orjan|last7=Selin|first7=Klara Hradilova|last8=Lenke|first8=Leif|last9=Ramstedt|first9=Mats|date=November 2008|title=The societal cost of alcohol consumption: an estimation of the economic and human cost including health effects in Sweden, 2002|journal=The European Journal of Health Economics|volume=9|issue=4|pages=351–360|doi=10.1007/s10198-007-0082-1|issn=1618-7598|pmid=18043953|s2cid=20912577}}{{Cite web|url=https://www.researchgate.net/publication/252250147|title=The Social Costs of Drug Abuse in Australia in 1988 and 1992 (PDF Download Available)|website=ResearchGate|language=en|access-date=2017-09-17}}
