Excessive drinking reduces the number and function of three important kinds of cells in your immune system–macrophages, T and C cells. Macrophages are the first line of defense against disease. They eat anything that’s not supposed to be there, including cancerous cells, and they sound the alarm if pathogens are present. They are the reason vaccines work and why you can’t get chicken pox twice. Your T cells already know how to kill those specific kinds of viruses. B cells are white blood cells that secrete cytokines that attack bacteria. When B and T cells are suppressed, your immune system is less efficient at identifying and destroying invading pathogens.

How Alcohol Can Affect Your Immune System.

So to, you know, wonder and just be curious since that’s the area that I, you know, do a lot of work in research. And I wondered myself and I was, um, even after 40 years of work in this field, uh, very concerned about what I kept learning about the impact on the immune system for risky drinking. So, um, it’s more easy to see people who’ve done heavy drinking, um, maybe have some complications, but who knew that just some overdoing it every now and then may have some really substantial impact on our health. So again, and you combine that with the stress that dr talked about, so your immune system is already in distress and uh, fighting to be strong. And then you add another, um, some foreign agent if you will, if you want to call alcohol that, um, to your immune system too.

Drinking and COVID-19

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 . 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. As mentioned previously, excessive alcohol consumption can reduce your immune system function over time.

  • Although the innate immune response is immediate, it is not specific to any given pathogen.
  • We make skincare treatments and customize them for your skin-related problems, genetics, lifestyle, and environment.
  • But in addition to that, you can go on to Facebook and type in sobriety groups or alcoholics anonymous meetings.
  • There are also sobriety groups or alcoholics anonymous digital meetings through social media, chat rooms, and telehealth calls.
  • It also puts people at higher risk for developing high blood pressure.
  • When people are stressed due to this crisis because of job, financial, relationship, or health reasons, they may look for a drink as a way of coping with our current stressors.

Clinicians have long observed an association between excessive alcohol consumption and adverse immune-related health effects such as susceptibility to pneumonia. These disruptions to the composition of the gut microbiota and to gut barrier function have important implications beyond the intestinal system. 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. The immune system is the most complex system in the human body and, indeed, one of the most important. It identifies and neutralizes harmful pathogens and keeps our bodies healthy.

Amount of alcohol

These bacteria are necessary for optimal health, and their presence helps prevent harmful bacteria from having the space needed to grow. By disrupting this microbiome, alcohol makes infection more likely to occur. Other common recreational drugs, such as cocaine or crystal methamphetamine (“meth,” “speed”), can leave your body dehydrated and exhausted, as well as lead to skin irritation. All of these things can make it easier for you to get infections.

does alcohol weaken your immune system

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. Although most research has focused on the effects of heavy alcohol consumption on the immune system, several studies have also confirmed that even moderate consumption can have significant effects on the immune system. 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.

Furthermore, there is also evidence implicating the direct involvement of hormones in the gender differences observed regarding alcohol consumption. There is clearly a need for a better understanding of the biological mechanisms underlying gender differences in ethanol consumption. In animal models, the consumption of ethanol only led to lower levels of white blood cells; however, the same amount of alcohol consumed as red wine resulted https://ecosoberhouse.com/ in no suppression of the immune response. This could be due to the action of certain compounds in red wine that could be contributing to prevent suppression of the immune system caused by alcoholReference Percival and Sims 27. Similarly, wine intake, especially red wine, has been identified as having a protective effect against the common coldReference Takkouche, Regueira-Mendez, Garcia-Closas, Figueiras, Gestal-Otero and Hernan 29.

  • The result is that the immune system is likely to weaken over time and cause several health issues beyond heart failure.
  • An alcohol use disorder may affect the white blood cells in the body, which are responsible for eliminating “killer” white blood cells.
  • Without the operation of this protein, the body is not as effective at fighting disease as it would typically be.
  • Although not directly correlated, the stress of mental illnesses that are provoked by excessive alcohol use can contribute to a low-functioning immune system.
  • Alcohol–immune interactions also may affect the development and progression of certain cancers.

Vomit that is inhaled into the lungs often contains bacteria. When combined with a suppressed immune system, this can be does alcohol weaken your immune system the perfect storm for a bad case of pneumonia. You may be more likely to get serious lung infections, such as pneumonia.

Long-Term Changes in the Immune System of a Regular Drinker

First, it’s important to know that the microbes living in your intestines, your gut’s microbiome, plays an important role in fighting diseases. This happens in many ways that we’re just beginning to understand.
