Credit: Shutterstock<\/p>\n<p>Researchers reviewing decades of evidence conclude that alcohol plays a major role in disease and injury, affecting everything from the immune system to the brain and heart.<\/p>\n<p>A major new review published in Addiction paints a sobering picture of alcohol\u2019s impact on health, linking drinking to dozens of diseases, infections, and injuries that affect nearly every organ system in the body.<\/p>\n<p>Researchers say some of alcohol\u2019s harms may lessen after people reduce or stop drinking, but many effects of long-term heavy use can persist for years \u2014 and in some cases may never fully reverse.<\/p>\n<p>Alcohol drives many diseases<\/p>\n<p>The World Health Organization\u2019s current International Classification of Diseases (ICD-11) identifies more than 60 diseases and injuries that are 100% attributable to alcohol use. Many are associated with chronic heavy drinking, including:<\/p>\n<p>Alcoholic cardiomyopathy (heart muscle disease)Alcohol-related liver disease, including cirrhosisAlcohol poisoningFetal alcohol syndromeAlcohol-induced pancreatitisAlcohol-related neurological disordersAlcohol also increases the risk of infectious diseases<\/p>\n<p>Recent evidence shows alcohol weakens immune defenses and damages liver function, increasing vulnerability to infections such as:<\/p>\n<p>TuberculosisPneumoniaHIV\/AIDSSexually transmitted infections<\/p>\n<p>Researchers note that alcohol-related impairment can also contribute to behaviors that increase infection risk.<\/p>\n<p>Alcohol Is Linked to Several Major Chronic Diseases<\/p>\n<p>The review identifies five major categories of noncommunicable disease linked to alcohol use. Researchers found that drinking is associated with a higher risk of several cancers \u2014 including cancers of the mouth, throat, liver, breast, colon, and cervix \u2014 as well as cardiovascular diseases such as high blood pressure, atrial fibrillation, and stroke.<\/p>\n<p>Other conditions linked to alcohol consumption include:<\/p>\n<p>Type 2 diabetesDementia and epilepsyLiver cirrhosisPancreatitisAlcohol Raises the Risk of Injury<\/p>\n<p>Even small amounts of alcohol can impair coordination, judgment, and reaction time. According to the review, injury risk depends not only on how much alcohol is consumed, but also on factors such as environment, activity, and use of other substances.<\/p>\n<p>Alcohol use is linked to higher rates of:<\/p>\n<p>Traffic accidentsFalls and other unintentional injuriesViolence and assaultInjuries affecting other people, not just the drinkerSome harms can reverse<\/p>\n<p>Some alcohol related harms can improve or decline when drinking is reduced or stopped:<\/p>\n<p>Short-term risks, including injuries and sexually transmitted infections, mostly occur during intoxication, so the risk drops when drinking stops.Alcohol temporarily weakens immune function. The immune system may recover after a person stops drinking, although long-term heavy drinking can leave lasting damage.Many chronic diseases linked to alcohol, including cirrhosis and heart disease, cannot be fully reversed. However, drinking less can slow their progression even when some damage remains. Some cardiovascular effects may improve within days to weeks after abstinence begins.Brain damage caused by heavy drinking may partly improve with long-term abstinence, although risks such as dementia can remain.Possible benefits remain disputed<\/p>\n<p>Senior author Dr. J\u00fcrgen Rehm, Senior Scientist at the Canadian Centre for Addiction and Mental Health (CAMH), comments: \u201cEven though we now know a lot about alcohol\u2019s effects on health, it is still controversial whether a little drinking is good for your heart. When examining both cohort studies and Mendelian randomization studies, and all their potential strengths and biases, we conclude that there is not enough evidence to rule out a beneficial effect of drinking on ischemic heart disease and ischemic stroke.\u201d<\/p>\n<p>Sinclair Carr, first author of the review, adds: \u201cOur review of the current evidence on alcohol\u2019s effects on health leads to a cautious but clear conclusion: alcohol is a major cause of disease and injury, and its harms outweigh any potential benefits.\u201d Sinclair Carr is a PhD candidate at the Department of Epidemiology, Harvard T.H.
