Moderate alcohol consumption and the immune system: a review

does alcohol weaken your immune system

In fact, with the emergence of COVID-19 (along with other recent respiratory illnesses), the term “compromised immune system” has become all too common over the past few years. Alcohol use can cause respiratory complications such as pneumonia, empyema, respiratory does alcohol weaken your immune system syncytial virus, tuberculosis, lung abscess, and adult respiratory distress syndrome (ARDS). Drink responsibly— Using alcohol to cope with negative Covid-19 related feelings could place a person on a path toward developing an alcohol use disorder, Koob cautions.

  • In the study of Xiao et al. [52] transplanted microbiota in mice from alcoholic to healthy, developed emotional symptoms, such as anxiety, which occurs during abstinence.
  • Acute alcohol intoxication impairs the antigen-presenting ability of these cells (Mandrekar et al. 2004).
  • Rodents have a much shorter life span and often require forced (i.e., not initiated by the animal) exposure to alcohol, which is stressful.

Modulation of Innate Immunity by Alcohol

Few studies have investigated the effects of alcohol abuse on complement activation and its relationship with the incidence and severity of infection; instead, the focus of studies on alcohol-induced alterations in complement has been on liver injury (Pritchard et al. 2008). However, alcoholic patients frequently have abnormally low levels of complement in the blood. In addition, animal studies have indicated that acute alcohol intoxication can decrease complement activation in response to tissue injury resulting from disruptions in blood supply (i.e., ischemic injury).

Moderate alcohol consumption ‘boosts immune system’

“Immune system recovery depends on how long you have been drinking, how much and how much damage you have done to your liver. Although your immune system may recover over time, at some point, liver damage becomes irreversible and your immune system will not recover.” “The only remedy for an immune system damaged from drinking alcohol is to stop drinking. If you are not able to drink in moderation, you should avoid alcohol,” Dasgupta says. It is no surprise that the key to boosting your immune system is a healthy lifestyle—which includes good nutrition, plenty of sleep, regular exercise, no smoking, and avoidance of stress.12 And if you drink alcohol, drinking in moderation is also on the list. Consuming alcohol likely slows your recovery since your immune system isn’t functioning at optimal levels when you are drinking.

Effects of alcohol on adaptive immunity

This can result in heightened cravings for alcohol that can lead to alcohol addiction, Sarkar explains. Research has shown that when alcohol is removed from the body, it activates brain and nerve cells, resulting in excessive excitability (hyperexcitability). If you drink more than 12 units of alcohol, you’re at considerable risk of developing https://ecosoberhouse.com/ alcohol poisoning, particularly if you’re drinking many units over a short period of time. After drinking 10 to 12 units of alcohol, your co-ordination will be highly impaired, placing you at serious risk of having an accident. The high level of alcohol has a depressant effect on both your mind and body, which makes you drowsy.

Such studies can be challenging to conduct in humans because of difficulties in obtaining accurate medical histories, maintaining adherence, confounding factors such as diet, sleep-wake cycles, and ethical considerations when studying large doses of ethanol. Rodent studies offer several advantages such as availability of transgenic models that can facilitate mechanistic studies. Rodents have a much shorter life span and often require forced (i.e., not initiated by the animal) exposure to alcohol, which is stressful. Moreover, a recent systematic comparison examining gene expression changes found that temporal gene response patterns to trauma, burns, and endotoxemia in mouse models correlated poorly with the human conditions (Seok, Warren et al. 2013). Nonhuman primates, on the other hand, voluntarily consume different amounts of alcohol and allow us to conduct studies in an outbred species that shares significant physiological and genetic homology with humans while maintaining rigorous control over diet and other environmental cues. 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).

Long-Term Effects of Alcohol on the Immune System

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. Alcoholic drinks containing antioxidants may cause less damage than other drinks because they help protect against some of the free radicals in ethanol. While any alcoholic drink can have negative effects on the body, beers or wines that contain vitamins, antioxidants and polyphenols may cause less damage to the immune system than heavy liquors. In a clinical case study reviewed in this issue, Trevejo-Nunez and colleagues report on systemic and organ-specific immune pathologies often seen in chronic drinkers. In such patients, alcohol impairs mucosal immunity in the gut and lower respiratory system. This impairment can lead to sepsis and pneumonia and also increases the incidence and extent of postoperative complications, including delay in wound closure.

This alteration allows the translocation of bacterial products to the systemic circulation. The gut-derived bacterial components together with LPS activate the immune cells localized in the systemic circulation or in target organs such as liver and brain. This causes the increase in pro-inflammatory components that can lead to alcohol liver disease or increased states of neuroinflammation.

Factors That Affect How Alcohol Affects Your Immune System

  • This effect may contribute to lung injury in response to inflammation (Holguin et al. 1998).
  • The ability of alcohol to alter both innate and adaptive immune defenses inevitably impacts how the immune system of even a moderate alcohol drinker can respond to infections.
  • The first point of contact for alcohol after consumption is the gastrointestinal (GI) system before it is absorbed into the bloodstream.
  • Monocytes are an immature form of these cells that circulate in the blood until they are alerted to the presence of a pathogen in a particular tissue.
  • Oftentimes, we aren’t thinking about how much or how often we consume alcohol or its effects on the body.

Only select substances can cross the intestinal barrier and move into the liver, the bile ducts and the portal vein being the major connection points between the liver and microbiome [31]. However, in certain contexts, when intestinal commensals and their products translocate from the intestinal lumen to the liver, hepatic immune responses may be affected [32]. For example, the number, functional activity, and maturational status of the hepatic Kupffer cells (KCs), a critical component of the hepatic innate immune system, are directly related to the concentration of gut-derived MAMPs [33]. Intestinal pathogenic bacteria facilitate immune-mediated liver injury by activating dendritic cells (DCs) and natural killer T (NKT) cells in the liver [34].

The effect of beer on the immune system may not be as significant as the effect of stronger alcoholic beverages, but it’s important to remember that beer and wine can cause adverse health effects and even suppress the body’s immune response in excessive amounts. However, women who drink more than two drinks on one occasion and men who drink more than three drinks on one occasion may experience more health complications due to their excessive alcohol consumption. Alcohol consumption can allow the hepatitis virus to persist as a chronic condition, and alcohol use disorder combined with hepatitis often accelerates liver disease progression.

With bars and restaurants shut down, many people are having virtual happy hours to socialize with friends. However, when researchers evaluate these potential factors, the risks outweigh any benefits. Alcohol also causes damage to nerves and pathways, which disrupts communication between essential organs and bodily functions.
