Together, that evidence is highly persuasive that alcohol increases the chances of breast cancer. To get a clearer picture of the health effects of alcohol, researchers and journalists must be far more attuned to the nuances of this highly complex issue. Longer and larger experimental trials have been used to test full diets, like the Mediterranean diet, and are routinely conducted to test new pharmaceuticals (or new uses for existing medications), but they’ve never been done to analyze alcohol consumption. Meanwhile, some authors of studies suggesting alcohol is unhealthy have received money from anti-alcohol organizations. We have been researching the health effects of alcohol for a combined 60 years. If you have concerns about your drinking, talk with your health care provider.
Alcohol use: Weighing risks and benefits
Overhydration sometimes occurs among athletes and outdoor laborers, but it can also be a sign of disease or damage to the hypothalamus. Some desert insects, such as Onymacris unguicularis, have evolved to drink substantially from nighttime fog. An exception is the common pigeon, which can suck in water directly by inhalation. Cats drink at a significantly slower pace than ruminants, who face greater natural predation hazards. Ruminants and most other herbivores partially submerge the tip of the mouth in order to draw in water by means of a plunging action with the tongue held straight.
Putting it in context: standard alcohol drink sizes
Be sure to ask your healthcare professional about what’s right for your health and safety. When taking care of children, avoid alcohol. The term “moderate” also may be used differently.
Factors affecting alcohol consumption and alcohol-related harm
- But there’s plenty of research to back up the notion that alcohol does lead to weight gain in general.
- That doesn’t mean drinking a lot of alcohol is good for you—but it does suggest that the science around alcohol and health is complex.
- Observational studies can still yield useful information, but they also require researchers to gather data about when and how the alcohol is consumed, since alcohol’s effect on health depends heavily on drinking patterns.
- And prolonged alcohol use can lead to mental health conditions like anxiety and depression.
- Keep reading for more information on how alcohol can affect your body.
- Both acute and chronic heavy use of alcohol can interfere with multiple aspects of the immune response, the result of which can impair the body’s defense against infection, impede recovery from tissue injury, cause inflammation, and contribute to alcohol-related organ damage.
Even drinking a little too much (binge drinking) on occasion can set off a chain reaction that affects your well-being. And prolonged alcohol use can lead to mental health conditions like anxiety and depression. That’s because alcohol can weaken your immune system, slow healing and make your body more susceptible to infection.
Heavy alcohol use raises the risk for fractures and even low levels of alcohol intake increase the odds for recurrent gout attacks. People who drink often are more liable to contract diseases like pneumonia and tuberculosis than people who do not drink too much. Both acute and chronic heavy use of alcohol can interfere with multiple aspects of the immune response, the result of which can impair the body’s defense against infection, impede recovery from tissue injury, cause inflammation, and contribute to alcohol-related organ damage.
“When your liver is drinking out of boredom overwhelmed by oxidizing alcohol, it generates molecules that inhibit fat oxidation,” Dr. Sengupta explains. But when you ingest too much alcohol for your liver to process in a timely manner, a buildup of toxic substances begins to take a toll on your liver. You probably already know that excessive drinking can affect you in more ways than one. During pregnancy, drinking may cause the unborn baby to have brain damage and other problems.
In addition to its effects on the brain, alcohol also affects the peripheral nervous system, which comprises the nerves outside the brain and spinal cord. More information about alcohol’s effects on the brain is available on NIAAA’s topic page on Alcohol and The Brain. Keep reading for more information on how alcohol can affect your body.

Once you’ve cut back on your drinking (so you’re at or below the recommended guidelines), examine your drinking habits regularly to see if you’re maintaining this level of drinking.
Excessive alcohol use includes:
The whole body is affected by alcohol use–not just the liver, but also the brain, gut, pancreas, lungs, cardiovascular system, immune system, and more. Excessive alcohol use can harm people who drink and those around them. More information about alcohol and cancer risk is available in the Surgeon General’s advisory.
In the past, moderate drinking was thought to be linked with a lower risk of dying from heart disease and possibly diabetes. The less alcohol you drink, the lower your risk for these health effects, including several types of cancer. Similarly, in randomized trials, alcohol consumption lowers average blood sugar levels. Observational trials suggest that alcohol consumption also raises the risk of specific subtypes of breast cancer that respond to these hormones. For example, randomized controlled trials show that alcohol consumption raises levels of sex steroid hormones in the blood. Such nuance is rarely captured in broader conversations about alcohol research—or even in observational studies, as researchers don’t always ask about drinking patterns, focusing instead on total consumption.
For example, any amount of drinking increases the risk of breast cancer and colorectal cancer. In the United States, moderate drinking for healthy adults is different for men and women. The evidence for moderate alcohol use in healthy adults is still being studied. People who are dependent on alcohol, or have other medical or mental health problems, should stop drinking completely. Alcohol consumption has developed into a variety of well-established drinking cultures around the world. Evidence of fermented drinks in human culture goes back as early as the Neolithic Period, and the first pictorial evidence can be found in Egypt around 4,000 BC.

Chronic, heavy drinking raises the risk for ischemic heart disease (heart problems caused by narrowed arteries) and myocardial infarction (heart attack). Scientific evidence about drinking alcohol goes back nearly 100 years—and includes plenty of variability in alcohol’s health effects. As an example, a highly cited study of one million women in the United Kingdom found that moderate alcohol consumption—calculated as no more than one drink a day for a woman—increased overall cancer rates.
Public Health
Your liver detoxifies and removes alcohol from your blood through a process known as oxidation. Dr. Sengupta shares some of the not-so-obvious effects that alcohol has on your body. We talked with hepatologist Shreya Sengupta, MD, about how alcohol use affects your body and your emotional health.
- “Drinking gives your body work to do that keeps it from going about its other processes,” Dr. Sengupta notes.
- Earlier this month, for instance, the media reported on a new study that found even small amounts of alcohol might be harmful.
- More information about alcohol’s effects on the brain is available on NIAAA’s topic page on Alcohol and The Brain.
- The definition of heavy drinking is based on a person’s sex.

Deaths from excessive alcohol use
Health agencies outside the U.S. may define one drink differently. Knowing your personal risk based on your habits can help you make the best decision for you. People who choose not to drink make that choice for the same reasons. Alcohol misuse over time can lead to pancreatitis, which can impair the production of digestive enzymes and can affect hormones that regulate blood sugar level. Drinking increases the risk of myopathy or muscle wasting. Drinking a lot on a single occasion slows the body’s ability to ward off infections–even up to 24 hours later.
Cirrhosis, on the other hand, is irreversible and can lead to liver failure and liver cancer, even if you abstain from alcohol. With continued alcohol use, steatotic liver disease can lead to liver fibrosis. When your liver finishes that process, alcohol gets turned into water and carbon dioxide.
“Drinking gives your body work to do that keeps it from going about its other processes,” Dr. Sengupta notes. But there’s plenty of research to back up the notion that alcohol does lead to weight gain in general. Eventually, you can develop permanent and irreversible scarring in your liver, which is called cirrhosis. If alcohol continues to accumulate in your system, it can destroy cells and, eventually, damage your organs. And that’s on top of the toll that alcohol use can take on relationships, not to mention the potential for financial strain and legal troubles. More on alcohol
