But unhealthy factors, like stress, smoking, or drinking alcohol, can be taxing for your immune system and make it harder for it to fight off infection. If you feel like you cannot control your drinking on your own, you may want to consider seeking addiction treatment. For example, depending on your level of alcohol use, quitting drinking may help resolve the first stage of alcohol liver disease. If you are drinking a lot, stopping or decreasing your alcohol use can also help your chances of not developing severe liver disease. Your immune system has several different cell types, each of which has a different but very important job to help keep you healthy. You can lower the risk of alcohol impacting your immune system by drinking less.
Acute alcohol intoxication impairs the antigen-presenting ability of these cells (Mandrekar et al. 2004). In addition, alcohol markedly affects the differentiation of dendritic cells in blood and tissues (Ness et al. 2008). The alcohol-induced defects in dendritic cell function include reduced levels of CD80 and CD86 on the cells’ surface (which are necessary to induce activation of T-cells) as well as reduced production of IL-12, which is critical for stimulating naïve CD4+ T-cells to become IFN-γ–producing Th1 cells. Future prospective patient studies that account for sex, age, cultural and socioeconomic background, alcohol type, timing of administration and mechanistic animal model studies on the gut microbiome and the immune system will be critical to better understand alcohol’s role in autoimmune diseases. In turn, this knowledge will help guide the creation of specific clinical recommendations on alcohol consumption in patients with autoimmune diseases as well as help identify protective immune and gut-derived biomarkers that could be used in the treatment of autoimmune diseases independently of alcohol.
How Alcohol Affects Your Seizure Risk
Both the innate and the adaptive immune response are critical for effective host defense to infectious challenges. Multiple aspects of both arms of the immunity response are significantly affected by alcohol abuse, as described mirtazapine and alcohol in the following sections. Alcohol also causes damage to the cells in the outside layer of your stomach and intestines. As a result, bacteria may leak from the GI tract into your bloodstream, which can itself make you sick. Also, bacteria that escape this area can change the immune system in your liver, which can lead to inflammation and, potentially, alcoholic liver disease.
That’s because your body already has processes in place that allow it to store excess proteins, carbohydrates and fats. So, your system prioritizes getting rid of alcohol before it can turn its attention to its other work. Cirrhosis, on the other hand, is irreversible and can lead to liver failure and liver cancer, even if you abstain from alcohol.

Alcohol and Bupropion: 4 Things to Know About This Risky Combination
- PMNs produce a host of bacteria-killing (i.e., bactericidal) molecules (e.g., myeloperoxidase, defensins, azurophil-derived bactericidal factors, bactericidal permeability-increasing protein, cationic proteins, gelatinase, and lactoferrin).
- Similarly, as with the Th1 responses, alcohol inhibits the ability of dendritic cells to promote Th17 responses, thereby favoring Th2 responses (Heinz and Waltenbaugh 2007).
- In addition, chronic alcohol can decrease the number of B-cells that produce an antibody type called IgA5 in one of the layers of mucous membranes (i.e., the lamina propria), which is indicative of altered mucosal immunity (Lopez et al. 1994).
- Within the GI tract, alcohol exposure can also alter the number and abundance of microorganisms present within the microbiome, all of which play an important role in normal GI function.
Moreover, the wide-ranging roles of the immune system present significant challenges for designing interventions that target immune pathways without producing undesirable side effects. Several lines of evidence show that the number and function of B-cells are reduced by chronic alcohol. For example, chronic alcoholics exhibit loss of B-cells in the periphery and a reduced capacity to generate protective antibodies (Cook et al. 1996). In addition, chronic alcohol can decrease the number of B-cells that produce an antibody type called IgA5 in one of the layers of mucous membranes (i.e., the lamina propria), which is indicative of altered mucosal immunity (Lopez et al. 1994).
Infection with viral hepatitis accelerates the progression of ALD, and end-stage liver disease from viral hepatitis, together with ALD, is the main reason for liver transplantations in the United States. The article by Dolganiuc in this issue explores the synergistic effects of alcohol and hepatitis viruses on the progression of liver disease as well as alcohol consumption’s injurious effect on liver antiviral immunity. Mandrekar and Ju contribute an article that homes in on the role of macrophages in ALD development, including recent insights into the origin, heterogeneity, and plasticity of macrophages in liver disease and the signaling mediators involved in their activation and accumulation. As reviewed by Szabo and Saha, alcohol’s combined effects on both innate and adaptive immunity significantly weaken host defenses, predisposing chronic drinkers to a wide range of health problems, including infections and systemic inflammation.
Macrophages and Alcohol-Related Liver Inflammation
Reducing or quitting drinking can lower alcohol-related damage and improve your overall health. But drinking can weaken this system, leaving us vulnerable to infections and diseases. 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. That’s because alcohol can weaken your immune system, slow healing and make your body more susceptible to infection. But there’s plenty of research to back up the notion that alcohol does lead to weight gain in general.
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. Certain immune system cells — T cells and B cells — originate in your bone marrow. Antibodies detect and get rid of substances that are harmful to your body, including bacteria and viruses. Monocytes express Toll-like receptor (TLR) 4, the PRR that is often responsible for recognizing LPS on the surface of Gram-negative bacteria. After binding to LPS, monocytes are activated and mature into macrophages that travel to the site of infection to secrete important cytokines for the inflammatory response.
In other studies, chronic alcohol feeding impaired Th1 responses to a hepatitis C virus protein, a defect that was hypothesized to result from impaired secretion of IL-2 and GM–CSF by dendritic and T-cells (Geissler et al. 1997). This alcohol-induced defect in Th1 immunity correlates with suppression of IL-12 secretion by macrophages and dendritic cells (Waltenbaugh et al. 1998). Thus, it appears that alcohol inhibits Th1 immune responses and may predispose the organism to Th2 responses and that this shift is at least partly mediated by suppression of IL-12. To elicit a response from the cell-mediated arm of the adaptive immunity, antigens need to be presented to the CD4+ and CD8+ T-cells. Studies in rodents found that chronic alcohol feeding can impair presentation of protein antigens in the spleen (Mikszta et al. 1995).
Meadows and Zhang discuss specific mechanisms through which alcohol interferes with the body’s immune defense against cancer. They note, too, that a fully functioning immune system is vital to the success of conventional chemotherapy. The clinical management of all of these conditions may be more challenging in individuals who misuse alcohol because of coexisting immune impairment. In the lungs, for example, alcohol damages the immune cells and fine hairs that have the important job of clearing pathogens out of our airway.
The antibodies can recognize and interact with antigens, and each B-cell produces antibodies that recognize only one specific antigen. These antibodies then will bind to any matching antigen molecules they encounter in the blood or on other cells, thereby marking them for destruction. Some B-cells, however, become memory cells that maverick sober living will remain dormant in the body for years and can be activated rapidly if a second infection with the same pathogen occurs. The activities of T-cells and B-cells are intricately intertwined through the actions of various cytokines to orchestrate an effective immune response to any pathogen the organism may encounter.
Alcohol can have a range of harmful effects on the body, which can diminish a person’s immune response and put them more at risk for COVID-19. Heavy alcohol use weakens the immune system, and a weak immune system demi lovato age makes it easier to get sick. However, there are signs that you can look for if you are concerned that your drinking might be affecting your immunity.
Alcohol abuse suppresses multiple arms of the immune response, leading to an increased risk of infections. The course and resolution of both bacterial and viral infections is severely impaired in alcohol-abusing patients, resulting in greater patient morbidity and mortality. Multiple mechanisms have been identified underlying the immunosuppressive effects of alcohol. These mechanisms involve structural host defense mechanisms in the gastrointestinal and respiratory tract as well as all of the principal components of the innate and adaptive immune systems, which are compromised both through alcohol’s direct effects and through alcohol-related dysregulation of other components. Analyses of alcohol’s diverse effects on various components of the immune system provide insight into the factors that lead to a greater risk of infection in the alcohol-abusing population. Some of these mechanisms are directly related to the pathology found in people with infections such as HIV/AIDS, tuberculosis, hepatitis, and pneumonia who continue to use and abuse alcohol.
