How Alcohol Impacts the Brain Northwestern Medicine

Though research on alcohol’s effects on weight is mixed, both moderate and heavy use has been linked to weight gain (16, 17). Research suggests that only about 2% of those who drink within these limits have an alcohol use disorder (3). This article explores alcohol’s effects on your health and reviews intake limits and recommendations. Even if cirrhosis can’t be fully reversed, stopping alcohol can greatly reduce its severity, increasing blood circulation and improving the regeneration of hepatocytes. Healthcare providers can measure this with a type of ultrasound called a FibroScan and a panel of blood tests called liver function tests (LFTs).

Other chronic diseases

1. According to Healthline, alcohol is believed to cause cancer by damaging DNA and other genetic material in cells.
2. Observational studies dating back to the early 1990s linked light to moderate drinking (one to two drinks per day) to a lower risk of heart disease.
3. Many reach for a cocktail or glass of wine to cope with a bad mood but it turns out that alcohol may be contributing to a vicious cycle of moodiness.
4. It can also lead to irritation of the lining of the stomach, called gastritis.

Showing your patients a standard drink chart (printable here PDF – 184 KB) will help inform them about drink equivalents and may help your patients to estimate their consumption more accurately. Alcohol interferes with calcium balance, vitamin D production, and cortisol levels, adding to the potential weakening of bone structure. As alcohol can impair coordination, it may also increase the risk of a fall that could cause a fracture.

While this may not reverse cirrhosis, it can go a long way toward slowing disease progression and reducing the risk of liver cancer or liver failure. According to the 2020–2025 Dietary Guidelines for Americans, moderate alcohol use is defined as up to one standard drink per day for women or two standard drinks a day for men. Although the liver is efficient in metabolizing small quantities of alcohol and regenerating new liver cells, drinking a large amount, even for a few days, can lead to fatty liver disease.

According to the Dietary Guidelines for Americans, U.S. Department of Agriculture, and U.S. Department of Health and Human Services, moderate drinking involves up to one drink per day for women and up to two drinks per day for men (1, 2). Females are at greater risk of alcohol-related liver disease in part because they produce less aldehyde dehydrogenase (ALDH), the enzyme maverick house sober living that breaks down acetaldehyde.

With progression, liver failure can lead to hepatorenal syndrome (HRS) in which the kidneys also start to fail. Around 50% of people die within two weeks of diagnosis, and 80% die within three months. If the damage is so extensive that the liver is no longer able to service the body’s needs, you are said to have decompensated cirrhosis, which leads to liver failure.

Deaths from excessive alcohol use‎

It also explains the consequences of heavy drinking and whether it’s possible to recover from liver damage after heavy alcohol use. According to the American Diabetes Association, individuals with diabetes should limit alcohol intake to one drink per day for women and two drinks per day for men. It is also important to never drink on an empty stomach and to monitor blood sugar levels closely when drinking alcohol. Evidence highlights an association between alcohol consumption and immune system function.

But when does drinking frequently cross the line into being problematic? To gain some insight into these concerns, we spoke with hepatologist Jamile Wakim-Fleming, MD. On average, the liver can metabolize 1 ounce of alcohol every hour. A blood alcohol level of 0.08, the legal limit for drinking, takes around five and a half hours to leave your system. Alcohol will stay in urine for up to 80 hours and in hair follicles for up to three months. For instance, women’s bodies have more fat and less water than men’s bodies, on average.

This is the most common bodily response to chronic alcohol use and may develop in as many as 90% of people who chronically drink more than 5 drinks per day (10, 11). Heavy drinking or heavy alcohol use is defined as binge drinking on five or more days of the past month (1). While enjoying an occasional alcoholic beverage is unlikely to harm your health, drinking in excess can have substantial negative effects on your body and well-being. If you have fatty liver disease, it may be reasonable to drink in moderation once any damage to the liver has been reversed. A 2017 animal study conducted by the University of California at San Francisco reported that it only took 21 binge-drinking sessions in mice to induce symptoms of early-stage liver disease. If the liver is healthy, fatty liver disease can be reversed, and hepatocytes can start to regenerate themselves over a relatively short period.

According to the National Institute on Alcohol Abuse and Alcoholism, drinking a lot on a single occasion can slow down the body’s ability to ward off infections, even up to 24 hours after drinking. Overall, it is recommended that both men and women limit their alcohol consumption to no more than one drink per day to reduce the negative impact on reproductive health and hormone levels. Alcohol use disorder is a medical condition that is characterized by a problematic pattern of alcohol use that leads to significant impairment or distress.

That can lead to fluid build-up in your extremities and lungs, and even to congested heart failure. While major American brands of beer have a 5% ABV measurement, many popular craft beers have higher alcohol content. That IPA you love might have an ABV of 7% or higher, so keep an eye on it when you’re knocking them back at your next summer barbecue. The good news is that within a year of stopping drinking, most cognitive damage can be reversed or improved.

For example, some studies suggest that moderate alcohol drinking can affect fertility for some women. Research also shows that heavy drinking by men may lower testosterone levels and affect the making of sperm. The risk increases to 54% when 50 g are consumed and 320% when 100 g are consumed. Other factors may contribute to the onset of cirrhosis with daily alcohol use. According to the long-standing Million Women Study conducted in the United Kingdom, drinking alcohol on an empty stomach increases the risk of cirrhosis compared to drinking alcohol with food. Consuming distilled spirits was also seen to increase the risk compared to drinking wine only.
