Even for people who aren’t particularly heavy drinkers. 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. 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.
Alcoholic beverages
- 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.
- Global strategy to reduce the harmful use of alcohol
- In the past, moderate drinking was thought to be linked with a lower risk of dying from heart disease and possibly diabetes.
- Most cultures throughout history have incorporated some number of the wide variety of “strong drinks” into their meals, celebrations, ceremonies, toasts and other occasions.
“That can leave them more vulnerable to infectious diseases.” Damaged DNA can cause a cell to grow out of control, which results in cancerous tumors. But prolonged alcohol abuse can lead to chronic (long-term) pancreatitis, which can be severe. But wait, you may be thinking, what about those headlines that claim red wine is supposed to be good for my heart? Warnings from the World Heart Federation go so far as to state that no amount of alcohol is safe for your ticker. They also help fend off inflammation and support healthy metabolism.
Excessive alcohol use
“We see lower levels of a specific kind of white blood cells called lymphocytes in people who drink heavily for long periods of time,” Dr. Sengupta reports. But even low amounts drinking when bored of daily drinking and prolonged and heavy use of alcohol can lead to significant problems for your digestive system. In reality, there’s no evidence that drinking beer (or your alcoholic beverages of choice) actually contributes to belly fat. In some situations, the risk of drinking any amount of alcohol is high.

Hydration and dehydration
Drinking too much alcohol can weaken the immune system, making the body a much easier target for disease. Heavy alcohol use can cause deficiencies in specific components of the blood, including anemia (low red blood cell levels), leukopenia (low white blood cell levels), thrombocytopenia (low platelet levels), and macrocytosis (enlarged red blood cells). Heavy alcohol use can disturb the endocrine system, disrupting the hormones that help maintain the body’s stability and health.
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. If you drink every day, or almost every day, you might notice that you catch colds, flu or other illnesses more frequently than people who don’t drink.
Brain
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. Canines lap water by scooping it into their mouth with a tongue which has taken the shape of a ladle.
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. 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 heavy drinking is unequivocally harmful to health.
Alcohol-related damage to nerves may also cause heart arrythmias (irregular heartbeat), postural or orthostatic hypotension (a drop in blood pressure due to a change in body position), diarrhea, and erectile dysfunction. 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. A high rate of consumption can also lead to cirrhosis, gastritis, gout, pancreatitis, hypertension, various forms of cancer, and numerous other illnesses.

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. Some of these strategies — such as watching for peer pressure, keeping busy, asking for support, being aware of temptation, and being persistent — can also be helpful for people who want to give up alcohol completely.

When to avoid alcohol
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.
Excessive alcohol use includes:
Alcohol manufacturers have previously expressed some willingness to finance the studies—similar to the way pharmaceutical companies finance most drug testing—but that has often led to criticism. Large, long-term, gold-standard studies are expensive. Again, that evidence is persuasive in combination. In observational trials, it also appears to lower the risk of diabetes. When the data from both types of studies point in the same direction, we can have more confidence in the conclusion.
Each of those consequences can cause turmoil that can negatively affect your long-term emotional health. Long-term alcohol use can change your brain’s wiring in much more significant ways. The morning after a night of over-imbibing can cause some temporary effects on your brain.
Yes, grabbing a few beers or a couple of glasses of wine or cocktails with friends can increase your heart rate — dangerously in some cases ACV may help lower blood sugar and calm acid reflux, but don’t believe all the hype An enzyme deficiency or rosacea are potential causes of alcohol flush “Alcohol tends to cause more problems than it solves for a lot of people,” Dr. Sengupta emphasizes.
