How Does Alcohol Consumption Affect the Immune System?

Moreover, some people shouldn’t https://knowledgestor.com/what-are-the-applications-of-nanotechnology-in-medicine/ 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. But drinking can weaken this system, leaving us vulnerable to infections and diseases. Your body breaks alcohol down into a chemical called acetaldehyde, which damages your DNA. Damaged DNA can cause a cell to grow out of control, which results in cancerous tumors. The intestinal microbiota (IMB) is the set of microorganisms that inhabit our intestines.

Equally important, however, is the immune system’s ability to detect tissue damage and direct the body’s response, including removing damaged tissue and assisting in subsequent tissue repair and regeneration. To perform all of these tasks, the immune system relies on an elaborate network of highly specialized cells that interact in https://communityfoodist.com/category/ethical-eating/ a tightly orchestrated way. One of the most profound impacts of alcohol on the immune system is its effect on gut health.

  • Alcohol consumption can damage these cells, making it easier for viruses to enter the body and proliferate.
  • The effect can linger for 6 months, but may go on longer if your grief is deep or doesn’t ease.
  • Because alcoholics are at increased risk for hepatitis B (HepB) infections, immunization with a HepB vaccine is recommended.
  • While your body is metabolizing alcohol, it has a lower ability to fight off infections and viruses, making you more vulnerable to developing a cold or more serious condition.

Moderate alcohol consumption is generally defined as up to one drink per day for women and up to two drinks per day for men. However, individual tolerance and health conditions should also be considered. Alcohol’s effects on the structural host defense of the gastrointestinal (GI) tract.

Which Health Risks Are Associated with a Weakened Immune System?

There is evidence in a number of physiological systems that binge alcohol intake complicates recovery from physical trauma (see the article by Hammer and colleagues). Molina and colleagues review research showing that alcohol impairs recovery from three types of physical trauma—burn, hemorrhagic shock, and traumatic brain injury—by affecting immune homeostasis. Their article also highlights how the combined effect of alcohol and injury causes greater disruption to immune function than either challenge alone. The main products of the fermentation of dietary fiber, SCFAs (acetate, propionate and butyrate principally) are considered as one of the main direct or indirect mediators of microbiota–gut–brain interactions 72.

Effects on Adaptive Immunity

In this strategy, both the substance abuse problem and the mental disorder are treated simultaneously. Regardless of which diagnosis (mental health or substance abuse problem) came first, long-term recovery will depend largely on the treatment for both disorders done by the same team or provider. In addition to its direct effects on the immune system, alcohol can have an indirect impact on immunity through its actions in the stomach and intestines (GI tract). The GI tract is one of the first parts of the body to come into contact with alcohol and, as a result, bears the brunt of alcohol’s harmful effects. The risk to the immune system is not necessarily from drugs or alcohol, but from the toll, they take on the body. Many substances cause dehydration, mental or physical fatigue, and lack of food or sleep, which can result in a weakened immune system.

One of the most significant immediate effects of alcohol is that it affects the structure and integrity of the GI tract. For example, alcohol alters the numbers and relative abundances of microbes in the gut microbiome (see the https://blogknowhow.org/understanding-the-importance-of-seeking-professional-advice-from-a-registered-dietitian/ article by Engen and colleagues), an extensive community of microorganisms in the intestine that aid in normal gut function. Alcohol disrupts communication between these organisms and the intestinal immune system. Alcohol consumption also damages epithelial cells, T cells, and neutrophils in the GI system, disrupting gut barrier function and facilitating leakage of microbes into the circulation (see the article by Hammer and colleagues).

What is Autoimmune Disease?

Alcohol has been linked to an increased risk of cancer, including cancers of the liver, mouth, and throat (i.e., upper aerodigestive tract), large intestine, and breast. The risk of harm differs depending on the type of cancer, the amount of alcohol consumed, and even genetic factors. Ultimately, the best way to prevent alcohol from affecting the immune system is to avoid using alcohol altogether. However, light drinkers (defined as less than one drink a day for women or less than two drinks a day for men) may be less likely to experience negative immune system effects than those who drink heavily. Our bodies are constantly exposed to a barrage of microbes, including bacteria, viruses, and fungi.

  • Still, the evidence is more robust for considering how much you’re drinking, rather than what you’re drinking.
  • Rodents have a much shorter life span and often require forced (i.e., not initiated by the animal) exposure to alcohol, which is stressful.
  • Heavy drinking is more likely to affect a person’s immune system than moderate drinking.
  • Several studies have also shown that the lungs are highly vulnerable to the effects of alcohol.
  • It depends on our overall health, but recovery starts as soon as we quit or cut back.
  • Both enzymes convert alcohol to acetaldehyde, which is further metabolized to acetate by acetaldehyde dehydrogenase (ALDH) in the mitochondria.

First, it’s important to know that the microbes living in your intestines, your gut’s microbiome, plays an important role in fighting diseases. When you drink a lot of alcohol, it has many negative effects on your digestive system. It damages the epithelial cells in your intestines, making it harder to absorb many nutrients.

How Alcohol Affects Your Immune System

  • Drugs and alcohol severely impact the immune system, leaving the body vulnerable to infections, chronic illnesses, and slower recovery.
  • Daily alcohol intake may turn an ordinary case of COVID-19 into a condition that requires hospitalization or that causes fatal results.
  • This will leave you feeling badly dehydrated in the morning, which may cause a severe headache.
  • It fights off harmful bacteria, viruses, and other invaders to keep you healthy.
  • 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.
  • While drinking alcohol can weaken your immune system, there are steps you can take to help you feel better the next day.

Alcohol significantly alters inflammatory signaling pathways, influencing cytokine production and activity. One major effect is its modulation of nuclear factor kappa B (NF-κB), a transcription factor regulating pro-inflammatory gene expression. Chronic alcohol exposure enhances NF-κB activation, increasing inflammatory mediators such as tumor necrosis factor-alpha (TNF-α), interleukin-6 (IL-6), and interleukin-1 beta (IL-1β). This persistent inflammatory state can contribute to tissue damage and exacerbate autoimmune conditions.

Drugs and Alcohol: Effects on your immune system

Both regulatory mechanisms related to miRNA and epigenetic mechanisms are interrelated (see figure 3). Thus, several miRNAs themselves are regulated epigenetically but also are capable of targeting genes that control epigenetic pathways (e.g., polycomb group-related genes and histone deacetylase). Studies have identified ethanol-mediated changes in both miRNA abundance (Miranda et al. 2010; Pietrzykowski 2010) and epigenetic modifications within PBMCs (Biermann et al. 2009; Bleich and Hillemacher 2009; Bonsch et al. 2006). However, very few studies have examined ethanol-induced changes in gene expression and regulation within specific immune-cell subsets. Moreover, none of the studies have conducted a comprehensive integrated analysis of mRNA, miRNA, and epigenetic expression patterns in the same cell(s) before and after alcohol consumption.
