But even two people who drink the same amount may be affected differently, depending on their genes and other risk factors. While some studies suggest that moderate drinking can benefit the heart, why is alcoholism considered a chronic disease others haven’t found such a link. Much of the research has focused on red wine, which contains antioxidants called polyphenols. Researchers have found an association between a polyphenol in red wine called resveratrol and a reduced risk of heart disease, primarily due to its anti-inflammatory effects. The most frequently cited definition of moderate drinking comes from the Centers for Disease Control and Prevention, which defines it as consuming one drink a day or fewer for biological women and two or fewer for men.
- The test is free, confidential, and no personal information is needed to receive the result.
- What people shouldn’t be doing is justifying their drinking because it’s supposed to be healthy, says Luis Seija, an internist and pediatrician at the University of Pennsylvania.
- The latter changes in these indices could be brought about by ethanol-induced imbalances in the reducing equivalents nicotinamide adenine dinucleotide (NAD) and nicotinamide adenine dinucleotide hydrogen (NADH), an important chemical pathway involved in oxidative stress.

Approximately 1 to 2 drinks per day may have no effect on or lead to a slight reduction in stroke events; however, greater daily alcohol levels increase the risk for all stroke events and incident stroke types. In terms of stroke subtypes, compared with nondrinkers, current alcohol drinkers have an increased risk (~14 percent) for hemorrhagic stroke (Ronksley et al. 2011). It is important to note that, unlike other studies with more discrete alcohol consumption categories, alcohol use was nonspecifically defined in INTERHEART as the consumption of at least 1 alcoholic beverage within the previous 12 months (Leong et al. 2014). Interestingly, the strength of this association was not consistent across different geographic regions.
- If acetaldehyde builds up in the body, it damages DNA and prevents cells from reproducing or repairing themselves.
- Mechanisms related to the positive and adverse effects of alcohol on cardiovascular conditions, such as coronary heart disease and stroke as well as cardiomyopathy.
- Countries where it’s historically been acceptable for parents to give their children alcohol, such as European countries, have also seen higher rates of heavy underage drinking, including binge drinking.
- For example, in one study, the ejection fraction decreased by 4 percent after alcohol consumption (Delgado et al. 1975).
- The internal environment changes drastically, causing symptoms of withdrawal.
Alcohol Use Disorder
People who drink heavily over a long period of time are also more likely to develop pneumonia or tuberculosis than the general population. The World Health Organization (WHO) links about 8.1 percent of all tuberculosis cases worldwide to alcohol consumption. That’s because drinking during pregnancy doesn’t just affect your health. Slurred speech, a key sign of intoxication, happens because alcohol reduces communication between your brain and body. This makes speech and coordination — think reaction time and balance — more difficult.
Sexual and reproductive health
These effects might not last very long, but that doesn’t make them insignificant. Impulsiveness, loss of coordination, and changes in mood can affect your judgment and behavior and contribute to more far-reaching effects, including accidents, injuries, and decisions you later regret. Some of these effects, like a relaxed mood or lowered inhibitions, might show up quickly after just one drink. Others, like loss of consciousness or slurred speech, may develop after a few drinks.
Can drinking raise my blood pressure?
You can expect to hear about more research, debate, and controversy in the near future regarding the potential risks and benefits of drinking, and how much — if any — is ideal. Alcohol has long been considered a «social lubricant» because drinking may encourage social interaction. Having a drink while getting together with family or friends is often part of many special occasions. The support of friends and family is important in the journey to recovery from alcohol use disorder (AUD). No matter how severe the problem may seem, evidence-based treatment can help people with AUD recover.
Alcohol’s Effects on Health
The brain adapts to the presence of alcohol and undergoes persistent changes. When alcohol use suddenly stops, the body is not accustomed to being alcohol free. The internal environment changes drastically, causing symptoms of withdrawal. This is also true for teenagers with a family history of alcohol dependence, who are at a higher risk for developing issues with alcohol. As research shows, waiting to start drinking can have an even greater impact on them.
Dysfunctional mitochondria are less efficient, can become a source of ROS, and are more likely to initiate apoptosis (Marzetti et al. 2013). Figure 3 summarizes the potential mechanisms underlying the cardioprotective and adverse effects of alcohol consumption. One or more mechanisms may be in effect and/or may cancel out another. This area of research was briefly outlined here; more comprehensive reviews on these mechanisms are available (Krenz and Korthuis 2012; Mathews et al. 2015). Of course, no one needs to wait for new guidelines or warning labels to Drug rehabilitation curb their drinking.
Beyond these physical and mental health risks, frequent alcohol misuse also is linked with personal problems, such as losing one’s driver’s license or having relationship troubles. For some people who drink, it takes quite a few drinks to “get a buzz” or feel relaxed, and they may be less likely to show signs of intoxication compared to others. Alcohol misuse refers to drinking in a manner, situation, amount, or frequency that could cause harm to the person who drinks or to those around them. Visit Canada’s low-risk alcohol drinking guidelines to learn about the recommended limits on the number of standard drinks men and women should have. According to https://ecosoberhouse.com/ the Centers for Disease Control and Prevention (CDC), 12 ounces of beer, 5 ounces of wine, and 1.5 ounces of 80-proof alcohol constitute one drink.
Short-term effects of alcohol
That misconception is rooted in a 1992 paper that found that moderate wine consumption protected French people against heart disease—even though their diet included plenty of meat, oil and butter. This conclusion was corroborated by more than 100 observational studies and even biological evidence, given that alcohol consumed in moderation increased the level of “good cholesterol,” thinned the blood and improved insulin sensitivity, Rimm says. Genetics or a family history of alcohol misuse increases that risk as well. Childhood trauma, mental health issues, and stress can also lead people to begin drinking or drink more than usual. Prenatal alcohol exposure can result in brain damage and other serious problems in babies. The effects are known as fetal alcohol spectrum disorders, or FASD, and can result in lifelong physical, cognitive, and behavioral problems.
Anton emphasizes that exercise doesn’t necessarily have a direct effect on how alcohol is metabolized, so it shouldn’t be an excuse to start drinking. “When people are thinking about drinking, and if they choose to do so, it should be part of a healthy lifestyle,” Rimm says. NIAAA Director George F. Koob, Ph.D., said that as of May 2023, the institute is not aware of specific health guidelines on alcohol consumption for transgender or gender-nonconforming individuals. The National Institute on Alcohol Abuse and Alcoholism (NIAAA) has information on how alcohol impacts your health. It also has resources to help those looking to change their drinking habits.
