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 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.
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.
What Does Alcohol Do to Your Body? 9 Ways Alcohol Affects Your Health
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.
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.
In interpreting human and animal alcohol studies, it is important to closely consider the administered quantity of alcohol. Patterns of human drinking are typically divided into light, moderate and heavy consumption. For humans, a standard alcoholic drink is defined as approximately 14 g of alcohol.22 According to the CDC, light drinking is considered to be three or fewer alcoholic drinks per week. Moderate drinking is defined as one alcoholic drink per day for women and two drinks per day for men, though variations across studies exist for this definition. Heavy alcohol consumption is defined as having four or more drinks/day for females and five or more drinks/day for males.22 Accurate human consumption can be challenging to quantify due to participant subjective memory and accurate reporting.
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 games for substance abuse groups 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.
Your liver detoxifies and removes alcohol from your blood through a process known as oxidation. When your liver finishes that process, alcohol gets turned into water and carbon dioxide. Dr. Sengupta shares some of the not-so-obvious effects that alcohol has on your body.
Autoimmune diabetes
“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. Alcohol feeding suppresses the production and secretion of certain acute-phase proteins (i.e., type II cell surfactant). This effect may contribute to lung injury in response to inflammation (Holguin et al. 1998).

Not only will drinking alcohol reduce your immune system’s strength, but alcohol also has a dehydrating effect. Moreover, some people shouldn’t drink at all, according to the Dietary Guidelines. This includes people who are pregnant, have alcohol abuse disorder, or are taking medications that interact with alcohol. The immune system is how your body defends itself from infections — like harmful bacteria and viruses — and prevents you from getting sick. But just like a muscle, the immune system can become weak and fail to protect you against infection as well.

- The course and resolution of both bacterial and viral infections is severely impaired in alcohol-abusing patients, resulting in greater patient morbidity and mortality.
- Alcohol consumption may be expected to contribute toward an increased risk of or exacerbation of autoimmune diseases given its pro-inflammatory properties.
- Significant differences between the immune system of the mouse—the primary model organism used in immune studies—and that of humans also complicate the translation of experimental results from these animals to humans.
- After eliminating pathogens by phagocytosis, the monocytes exhibit pathogen-derived proteins and other molecules (i.e., antigens) on their surfaces.
Thus, both types of immunity are mediated partly by the actions of specific immune cells (i.e., include a cell-mediated response) and partly by the actions of molecules secreted by various immune cells (i.e., include a humoral response). 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.
These molecules help recruit and activate additional PMNs as well as macrophages to the site of an injury or infection. The body constantly is exposed to pathogens that penetrate either our external surface (i.e., the skin), through wounds or burns, or the internal surfaces (i.e., epithelia) lining the respiratory and gastrointestinal (GI) tracts. The first line of defense is called the innate immunity;1 it otc xanax exists from birth, before the body is even exposed to a pathogen. It is an immediate and rapid response that is activated by any pathogen it encounters (i.e., is nonspecific); in addition, it plays a key role in the activation of the second level of the immune response, termed the adaptive or acquired immunity. This part of the immune response is specific to one particular pathogen and also creates an “immune memory” that allows the body to respond even faster and more effectively if a second infection with the same pathogen occurs. Both innate and adaptive immunity rely on a multitude of different cells and molecules.

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 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.
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.
