“Research shows a link with the gut microbiome, the gut-brain access, and craving for alcohol,” says Dr. Jennifer Barb, head of the Data Analytics and Translational Science Unit at the National Institute of Health Clinical Center. Addiction to booze, she says, is similar to addiction to highly processed food. Both can cause dysbiosis, or an imbalance in the microbiome, that can privilege bad bacteria over good. “Healthy gut bacteria is not used to metabolizing alcohol, so other bacteria may be sending signals to the brain”—telling you that you want more. There are various reasons to drink, from enhancing a meal to celebrating special occasions. “Many people find it easier to interact and have fun and maybe feel a little less reserved” while drinking, says Raymond Anton, an addiction psychiatrist at the Medical University of South Carolina.

Pancreatitis can be a short-term (acute) condition that clears up in a few days. But prolonged alcohol abuse can lead to chronic (long-term) pancreatitis, which can be severe. But there’s plenty of research to back up the notion that alcohol does lead to weight gain in general. In reality, there’s no evidence that drinking beer (or your alcoholic beverages of choice) actually contributes to belly fat. “Some people think of the effects of alcohol as only something to be worried about if you’re living with alcohol use disorder, which was formerly called alcoholism,” Dr. Sengupta says. But it conversely found that the risk of dying from alcohol use begins at low levels of average use and increases as levels of alcohol consumption increases.
Health Conditions
- An important component of the innate immune system, the liver produces a wide variety of antibacterial proteins.
- Frequent and heavy alcohol consumption can suppress the immune system, making the body vulnerable to viruses and infections.
- Adequate sleep helps the body fight off infections and viruses, and the less sleep you get, the less your immune system can protect your body.
- The most obvious is the amount of alcohol consumed; a heavy drinker will be exposed to more acetaldehyde than a light drinker, leading to more damage.
- For example, one study found that women who consumed 330 mL of beer for 30 days exhibited a significant increase in leukocytes, mature CD3+ T-cells, neutrophils, and basophils.
Since DNA controls cell function and growth, damaged DNA can cause cells to grow uncontrollably and develop tumors. According to Favini, a moderate amount of drinking — one drink per day for women, and two drinks per day for men per the United States Dietary Guidelines for Americans — is generally safe for people in good health and unlikely to have a negative effect on their immune systems. For example, a 2015 study in the journal Alcohol found that binge drinking can reduce infection-fighting white blood cells known as monocytes in the hours after peak intoxication, essentially weakening your immune system. Plenty of factors influence how damaging acetaldehyde is to the body, Wakeman says. The most obvious is the amount of alcohol consumed; a heavy drinker will be exposed to more acetaldehyde than a light drinker, leading to more damage.
Alcohol & The Immune System: Does Drinking Lower Your Immune System?
The question is not how much alcohol it will take to cause an effect, but how great the effect will be.

Does Drinking Alcohol Decreases Your Immune System?
And it’s not just that you’re more likely to get a cold — excessive drinking is linked to pneumonia and other pulmonary diseases. It can also lead Substance abuse to a wide range of health problems, including high blood pressure and heart disease, liver disease, and increased risk of cancer. This defect was rescued when cultures were treated with the Rho kinase inhibitor, Y27632 indicative that ethanol reduced efferocytosis through the induction of Rho kinase activity in a dose-dependent manner (Boe, Richens et al. 2010). In addition, female mice that consumed 20% (w/v) ethanol for 8 weeks showed a reduction in LPS activated efferocytosis (Boe, Richens et al. 2010).
Drinking impairs immune cells in key organs
Experiments done in an immortalized line of human T lymphocyte cells used in cancer research (i.e., Jurkat cells) found that exposure to different concentrations of ethanol (i.e., 25, 50, 100, 150, 200 mM) for 24 hours resulted in decreased cell viability in a dose-dependent manner. Furthermore, ethanol exposure decreased expression of the anti-apoptotic molecule Bcl-2 and promoted expression of the pro-apoptotic molecule BAX in the cells. These findings suggest that ethanol https://ecosoberhouse.com/ pretreatment can sensitize T cells to AICD (Kapasi et al. 2003). In vivo studies in humans confirmed these observations, demonstrating that binge drinking (i.e., consuming 5 to 7 drinks within 90 to 120 minutes) promoted T-cell apoptosis and decreased Bcl-2 expression (Kapasi et al. 2003). In addition to pneumonia, alcohol consumption has been linked to pulmonary diseases, including tuberculosis, respiratory syncytial virus, and ARDS.

Several studies have demonstrated the dose-dependent effect that alcohol has on preventing both monocytes and macrophages from binding to the bacterial cell wall component lipopolysaccharide (LPS). Ethanol is primarily metabolized in the stomach and liver by alcohol dehydrogenase (ADH) and cytochrome P450 2E1 (CYP2E1) (Zakhari 2006). ADH is present in the cytosol whereas CYP2E1 is present predominantly in microsomes.
- In addition, production of IL-10 in response to TLR2/6 stimulation was increased (Pruett, Zheng et al. 2004).
- Moreover, immune systems of several nonhuman primate species are similar to those of humans and these animals are susceptible to several clinically important pathogens making them a valuable model to study the impact of ethanol on immunity (Hein and Griebel 2003).
- These articles detail how alcohol affects the immune system and how researchers are harnessing this knowledge to help prevent and treat alcohol-related harm.
- It can also lead to a wide range of health problems, including high blood pressure and heart disease, liver disease, and increased risk of cancer.
Want to stop harmful drinking? AA versus SMART Recovery
Alcohol disrupts ciliary function in the upper airways, impairs the function of immune cells (i.e., alveolar macrophages and neutrophils), and weakens the barrier function of the epithelia in the lower airways (see the article by Simet and Sisson). Often, the alcohol- provoked lung damage goes undetected until a second insult, such as a respiratory infection, leads to more severe lung diseases than those seen in nondrinkers. Because of those negative effects, people who suffer from an alcohol use disorder (AUD) or drink too much too often are more susceptible to diseases and infections. Alcohol addiction delivers a devastating one-two punch by both hindering the body’s defenses and leaving organs vulnerable to disease.
Finally, in recent work from our group we found that mice fed a binge-on-chronic ethanol diet exhibited reduced recruitment of NK cells and T cells to the lungs in response to bacterial pneumonia compared to control mice (83). While NK-cell numbers and function are detrimentally affected by alcohol, it does not appear to affect the frequency of group I ILC. Similarly, an increased percentage of CD8 T cells expressing HLA-DR and CD57 was reported in the group of male alcoholics with self reported average alcohol consumption of approximately 400g/day for approximately 26 years (Cook, Ballas does alcohol suppress immune system et al. 1995).
