Our mission is to provide high-quality, science-backed supplements that empower our community to take control of their health. In this blog post, we’ll explore the intricate relationship between alcohol and our immune system, shedding light on how our choices can either bolster or undermine our well-being. Additionally, alcohol can interact with medications commonly prescribed for respiratory conditions, such as bronchodilators and steroids, potentially reducing their effectiveness or leading to unwanted side effects. Over time, this can result in reduced lung capacity, difficulty breathing, and an overall decline in respiratory function. For individuals with preexisting conditions like asthma or chronic obstructive pulmonary disease (COPD), alcohol can exacerbate symptoms and make it even harder to breathe.
- When we consume alcohol, it enters the bloodstream and affects various organs, including the liver, lungs, and gastrointestinal (GI) tract, which play crucial roles in immune health.
- Chronic alcohol consumption can impair the function of immune cells in the lungs, making it harder to clear out pathogens.
- White shares that drinking to cope with negative emotions is one of the strongest predictors of developing alcohol use disorder.
- It’s a common infection, but it can cause serious health complications if left untreated and spread breaks in the skin, such as cuts, bites, ulcers, and puncture wounds, which can allow bacteria into the skin.
- This same treatment also inhibited the in vitro production of IL-6 and IL-12 by peritoneal macrophages harvested 2 hours following injection of LPS (Pruett, Fan et al. 2005).
Can Alcohol Cause a Weak Immune System? Understanding the Connection
The damage is irreversible because scar tissues build up and replace the liver’s regenerative cells, preventing the organ from healing. 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.

Ferroptosis within the tumor microenvironment is well-studied; however, the hepatic microenvironment remains understudied and represents a burgeoning area of inquiry. The gut-liver axis is indispensable in the study of the hepatic microenvironment. Specifically, intestinal barrier disruption leads to microbiota translocation and endotoxinemia, triggering hepatic immune cell activation and the secretion of inflammatory cytokines, which can further exacerbate hepatic injury 162. A plethora of preclinical study models has substantiated that the dysregulation of the gut-liver axis and the impetus of inflammatory mediators exert a biphasic effect on the process of ferroptosis, with a mechanism that is intricate. For instance, certain metabolic byproducts of intestinal bacteria have the capacity to suppress the process of ferroptosis in the context of intestinal ischemia–reperfusion injury 163, 164.
GPX4 is essential for the liver, and its low level primarily ensures the integrity of PL-PUFA in a healthy liver, but this stable condition may be altered in several metabolic problem liver disorders Alcohol Use Disorder 49. Furthermore, GPX4 is widely recognized as a tumor suppressor, and the GSH/GPX4 axis plays a crucial role in restraining the metabolism of cancer cells when catalytically active iron is present (Fig. 2) 50. In healthy human tissues, the generation of ROS is a natural physiological occurrence. In pathological conditions, heightened metabolic activity and increased oxidative stress often leads to the catalysis of the Fenton reaction, resulting in the production of hydroxyl radicals (•OH). Some alcoholic beverages contain components that combat ethanol’s damaging effects.
Impact on Lung Health
- Studies focusing on the impact of pollutants on wild frog populations have shown that the introduction of contaminants can decrease frog population size, genetic diversity, and overall amphibian health.
- These medications also increase the risk of infections and may increase the risk of cancer.
- “Alcohol intake can kill normal healthy gut bacteria, which help to promote health and reduce risk of infection,” Mroszczyk-McDonald said.
- Combined differences in pharmacokinetics may increase the vulnerability of women to the effects of ethanol.
- The damage is irreversible because scar tissues build up and replace the liver’s regenerative cells, preventing the organ from healing.
White shares that drinking to cope with negative emotions is one of the strongest predictors of developing alcohol use disorder. Every glass chips away at your brain’s natural ability to manage those feelings. By illuminating the key events and mechanisms of alcohol-induced immune activation or suppression, research is yielding deeper insights into alcohol’s highly variable and sometimes paradoxical influences on immune function. The insights summarized in this issue of ARCR present researchers and clinicians with opportunities to devise new interventions or refine existing ones to target the immune system and better manage alcohol-related diseases.
- The fact that alcohol, even in small amounts, can harm frogs should serve as a wake-up call.
- Alcohol affects the reflexes that protect the lungs from aspiration—the accidental inhalation of food, liquid, or stomach acid into the airways.
- Other types may affect the abundance of GPX4 or other fundamental regulators of ferroptosis through alternative pathways.
- They inhibit the function of white blood cells called neutrophils, which are the body’s first line of defense against infection and injury.
According to this study, the mechanism would entail a disturbance of iron homeostasis, which would lead to a build-up of lipid ROS and subsequently improve sorafenib’s therapeutic efficacy. CDGSH iron-sulfur domain 1 (CISD1) functions as a negative regulator of ferroptosis in HCC, with upregulation observed following erastin treatment 43. Reducing iron toxicity accumulation and mitochondrial dysfunction through CISD1 gene inhibition enhances the process of erastin-induced iron ptosis, which does not involve GPx4 43. The aforementioned fundamental regulator of ferroptosis, ACSL4, also serves as a key predictor of cellular susceptibility to ferroptosis 88. In liver tissues of patients who exhibit a positive response to sorafenib, ACSL4 is highly expressed, whereas the opposite is observed in patients with poor treatment outcomes 88.
The retinoblastoma protein (Rb), a pivotal tumor suppressor, is commonly deactivated in the pathogenesis of various malignancies 202. Interestingly, loss of Rb activity does not worsen HCC progression; rather, by exacerbating ferroptosis, it improves sorafenib’s effectiveness to treat liver cancer 202. The enzyme acyl-CoA synthetase long-chain family member 4 (ACSL4), pivotal in chemical process of lipids, facilitates iron overload and mitigates hepatic damage as well as fatty acid peroxidation 76. When embedded inside membranes, PUFAs initiate oxidation, subsequently triggering extensive lipid peroxidation and the onset of iron-death 78.

But perhaps, for a moment, you may pause to reflect on your habits—how the last drink made you feel and how it might impact your health in the future. If you are considering cutting back, here are some simple, actionable steps you can take to limit or completely avoid alcohol. “While alcohol can make you drowsy, it fragments sleep cycles and suppresses REM sleep, the deep stage crucial for memory, learning and cognitive function,” says Andrews. She explains that alcohol reduces sleep quality by increasing nighttime awakenings and decreasing restorative sleep.
Talking to a healthcare provider before starting any new eating plan is a good idea. Salmon and other oily fish contain high omega-3 fatty acids, which have anti-inflammatory properties. Some research suggests higher intakes of omega-3s can lessen your risk of allergy and asthma symptoms. Experts recommend that most adults eat at least two servings of fish per week.
Is There Any Amount of Alcohol That’s OK to Drink?
So far, it has been demonstrated that subcellular cells undergoing ferroptosis may evolve at least three different pivotal features. By investigating the profound alterations in iron metabolism, we can acquire a meticulous comprehension of the onset and progression of ferroptosis-related disorders. While it can suppress the rapid, non-specific responses of innate immunity, it also interferes with the adaptive immunity’s specialized responses. For adaptive immunity, alcohol can cause miscommunication among cells and reduce the immune system’s ability to remember and counteract specific threats. While enjoying a single drink might not sound the alarms throughout the entire immune system, even moderate drinking can extend the time it takes your body to recover from illnesses.
How Alcohol Can Affect Your Immune System
The airways are lined with tiny hair-like structures called cilia, which play a crucial role in maintaining lung health. Cilia act like microscopic brooms, sweeping mucus, debris, and pathogens out of the lungs. This process, known as mucociliary clearance, is essential for keeping the airways clean and functioning properly. The lungs are constantly exposed to environmental pollutants, bacteria, and viruses. To protect against these threats, the respiratory system relies on a robust immune defense.
Research indicates that NADPH functions in concert with FSP1 to convert CoQ10 into CoQ10-H2, a strong antioxidant that stops peroxidation of fatty acids from spreading across cell membranes(Fig. 3) 63. The processes by which the liver maintains glucose homeostasis are bidirectionally regulated by iron homeostasis. In type 2 diabetes and NAFLD, increased hepatic gluconeogenesis contributes to hyperglycemia, while mitochondrial electron transport chain (ETC) dysfunction leads to ROS accumulation and disrupted iron homeostasis 150. Mitochondrial complex defects (e.g., Cox10 deficiency) inhibit pyruvate-to-acetyl-CoA conversion, upregulate PDK4, and thereby block glucose metabolism and exacerbate lipid accumulation, forming a vicious cycle 151.
