A pathological hallmark of ARDS is heterogeneous damage of the alveolar epithelium, with complete loss of the epithelial surface in some areas, whereas other alveoli remain relatively intact. Because one of the cardinal features of ARDS is disruption of the alveolar epithelial barrier that regulates the fluid content of the airspace, this was a logical target for investigation. This original study was limited by the uncertain accuracy regarding the diagnosis of an underlying AUD in the database. ARDS develops in response to inflammatory stresses, including sepsis, trauma, gastric aspiration, pneumonia, and massive blood transfusions (Ware and Matthay 2000). More than 1,000 years later, Hippocrates—who is regarded as the father of Western medicine—noted that wine has a variety of medicinal uses and is specifically beneficial for reducing sputum production (Lucia 1963); again, however, it is not clear if he was referring to asthma as we currently define the syndrome. Specifically, alcohol decreases saliva production in the salivary glands located in front of the ears (i.e., the parotid glands) (Dutta et al. 1989), thereby eliminating an important mucosal defense within the oral cavity.
Richards determined that modest and biologically relevant concentrations of alcohol (0.13%–0.16% or 8–34 mM) caused concentration-dependent hyperpolarization and suppression of membrane action potentials in canine tracheal smooth muscle preparations (Richards et al., 1989). A study by Puszkin in 1975 demonstrated that ethanol and its metabolite, acetaldehyde, are capable of reversibly inhibiting adenosine monophosphate-(ADP) induced re-association of skeletal muscle cell actin and myosin (Puszkin and Rubin, 1975). However, alcohol levels of 200–300 mM are rare but have been recorded in heavily intoxicated individuals treated in emergency departments. Fleisch’s findings extended an earlier report that very high concentrations of ethanol (2.4 % or 500 mM) inhibited antigen-induced histamine release from guinea pig lung tissue (Mongar and Schild, 1957).

Understanding the impact of alcohol on lung health is crucial to comprehend the potential risks involved. Researchers are still examining the possible impacts of alcohol consumption on the lungs of a person with COPD. Whether you’re a wine drinker or a whiskey aficionado, it’s important to understand how your favorite alcoholic beverage may affect your lungs. A study led by researchers from Loyola Medicine and End Stage Alcoholism Loyola University Chicago has discovered a potential new health concern related to excessive alcohol consumption.
This is in part because the association between alcohol abuse and acute lung injury was made relatively recently and remains largely unrecognized, even by lung researchers. This translates to tens of thousands of excess deaths in the United States each year from alcohol-mediated lung injury, which is comparable to scarring of the liver (i.e., cirrhosis) in terms of alcohol-related mortality. If you or a loved one is struggling with lung problems and alcohol addiction, don’t wait to seek help. Inpatient treatment centers for alcohol commonly offer both medical detox services and rehabilitation programs for overcoming all aspects of a person’s addiction. People that are addicted to alcohol often require medical support to quit drinking.
Additionally, alcohol can weaken the immune system, making individuals more susceptible to respiratory infections such as pneumonia. This suppression can lead to slower and shallower breathing, potentially resulting in decreased oxygen intake and impaired oxygen exchange in the lungs. One of the primary effects is the suppression of the central nervous system, which includes the respiratory centers in the brain.
- After inpatient treatment, the next step is often a partial hospitalization program (PHP), which is held for several hours each day for four to six weeks.
- In addition, researchers have identified several regulatory molecules that may play crucial roles in the alcohol-induced disease processes.
- Normally, the lungs are responsible for taking in oxygen and removing carbon dioxide from the body.
- A retrospective autopsy study among male veterans showed an inverse relationship of alcohol consumption to emphysema.22 The Lung Health Study in 5887 Canadian smokers with airways obstruction23 found a significant protective effect of moderate drinking in men, but not women, for both hospitalizations and deaths.
- Although we have not yet conclusively proven Burch’s hypothesis, there is growing evidence that alcohol plays a role in the pathogenesis of COPD.
- These conditions can significantly impair lung function and overall respiratory health.
Understanding Non-Residential Treatment (PHP, IOP, Virtual IOP)
By adhering to these guidelines, you can reduce the potential negative impact of alcohol on your lungs and overall health. The first and most important step in protecting your lung health while consuming alcohol effects on lung health alcohol is practicing moderation and responsible drinking. If you have concerns about alcohol consumption and its impact on your lung health, it is recommended to consult with a healthcare professional. Moreover, chronic inflammation induced by alcohol consumption may contribute to the development of lung cancer.
Several years later Lange, in a larger and longitudinal population study from Copenhagen, examined 8,765 persons over five years with alcohol intake histories, smoking histories and pulmonary function tests (Lange et al., 1988). Interestingly, this study found the same relationship of alcohol intake with symptoms and function changes in women, although the effects of alcohol were more prominent in men. A second population study by Lebowitz surveyed symptoms of cough, wheeze and dyspnea, measured pulmonary function and captured physician-confirmed diagnoses of respiratory disease in 3,800 subjects in the Tucson Arizona area (Lebowitz, 1981). This study used data from a cohort of 2,539 community dwelling adults that quantified alcohol intake, smoking, diet and other health factors and measured FEV1 on spirometry. The first large population study that examined the relationship of alcohol consumption to airway obstruction was a cross-sectional analysis published by Cohen in 1980 (Cohen et al., 1980).
Synergistic Risks for Lung Damage
- In addition to respiratory depression, opioids can affect almost any aspect of respiration.
- Another study in cultured human bronchial epithelial cells found that alcohol caused a concentration- and time-dependent increase in the expression of the tracheo-bronchial mucin (TBM) gene (Verma and Davidson, 1997).
- NHANES conducts interviews and physical examinations to assess the health and nutritional status of Americans.
- Studies of mucociliary function in animals drinking alcohol have provided important information about both the impact and the mechanism of alcohol-impaired airway clearance in vivo.
- However, it’s important to note that even moderate alcohol consumption has been linked to an elevated risk of lung cancer compared to abstaining from alcohol altogether.
While moderate drinking is less dangerous than excessive drinking, it is important to avoid drinking alcohol at all if you have concerns about your cardiovascular health or concerns about blood clots. The American Heart Association (AHA) does not recommend drinking alcohol because of its risk of heart damage, including increased risk of blood clots. Since many people do not know how much an appropriate serving is, the result for too many was dangerous consumption of alcohol, which did not incur any benefit benzo belly to heart health and may have increased the risk of blood clots and other issues for many Americans. For people with a family history of blood clots or heart disease, drinking a moderate amount of wine or beer, especially red wine, may confer some benefits because one serving of alcohol can slightly thin the blood. This is not just alcohol poisoning or drunk driving, but chronic health problems like heart disease.
When it comes to the impact on lung health, the combination of alcohol and smoking can have particularly detrimental effects. Research has shown that excessive alcohol intake can impair the function of immune cells in the lungs, inhibiting their ability to fight off pathogens and increasing the risk of infection. In this section, we will explore the connection between alcohol and lung health, as well as how alcohol consumption affects your lungs. There also may be some concerns about alcoholic patients’ compliance with chronic oral treatments, such as zinc and SAMe supplements.
IP alcohol, at 5–21% concentrations that induced coma, caused concentration- and time-dependent slowing of clearance of inhaled staphylococci in mice. These authors determined that very high concentrations of alcohol (4–10% or 0.8–3.2 M) caused concentration-dependent ciliostasis (Nungester and Klepser, 1938; Purkinje and Valentine, 1835) while lower concentrations (1%) did not (Dalhamn et al., 1967). In contrast, half of the subjects with a history of “mild” alcohol ingestion, defined as less than one drink per week and no more than two drinks on one occasion, clearance was significantly slowed by alcohol. As a group there was no difference between particle clearance rates following alcohol or juice alone but the variance of clearance time was greater following alcohol ingestion and was related to each subject’s previous alcohol intake history. Venizelos measured radiolabelled particle clearance in 12 normal volunteers following ingestion of a standard alcohol drink (0.5 g alcohol/kg in juice) or juice alone (Venizelos et al., 1981). Failure of this system results in recurrent bronchitis, pneumonia and airway deformity in the form of bronchiectasis (Noone et al., 2004).

The combination of impaired innate and adaptive immune responses within the airways is exacerbated by decreased white blood cells (i.e., lymphocytes) within the body’s immune system tissues (i.e., lymphoid tissue) in alcoholics, further stressing an already suboptimal response to infection (Gamble et al. 2006; Happel and Nelson 2005; Nelson and Kolls 2002). In experimental animal models, alcohol ingestion impairs the function of hair-like projections from cells (i.e., cilia) that sweep mucus out of the lungs, in part by disrupting the normal coordinated ciliary beating that clears pathogens from the airway (Wyatt et al. 2004). In parallel, defects in the function of the upper airway’s clearance mechanisms in alcoholic patients also play a role.
Specifically, alcohol ingestion, via angiotensin II, activates activity of the enzyme NADPH oxidase within the lung, which in turn increases the production of highly reactive and damaging free radicals known as reactive oxygen species (Polikandriotis et al. 2006). In contrast, NAC, which for unknown reasons only restores cytosolic glutathione, is less effective at modulating alcohol-mediated liver disease in those models (Fernandez-Checa et al. 1993). Subsequent experimental findings have delineated the complexities of lung glutathione homeostasis and how it is affected by alcohol.
However, many patients with AUD seek care for their addiction precisely because they are motivated to become or remain healthy and, consequently, are likely to adhere to their treatment regimen. For example, as discussed previously, clinical studies have shown that even otherwise-healthy people with AUD have glutathione and zinc deficiency within the alveolar space (Mehta et al. 2013; Moss et al. 2000). However, this ideal will be impossible to achieve in any meaningful timeframe and it therefore is critical to identify, test, and validate therapeutic strategies that can limit the morbidity and mortality of alcohol-related diseases, including acute lung injury and pneumonia. Clearly, as with all alcohol-related health issues, the ideal treatment would be abstinence in people with underlying AUD and/or a safe level of consumption in people who choose to drink for social reasons. Overall, these alterations in host defense and immune dysfunction explain how chronic excessive alcohol ingestion predisposes to pulmonary infection.
This alcohol-induced ciliary dysfunction (AICD) contributes to mucus buildup and makes the lungs more susceptible to illness. The volatility of alcohol allows it to move from the bronchial circulation across the airway epithelium and into the conducting airways of the lung, where it can cause damage to the airway cells. Additionally, alcohol consumption has been linked to an increased risk of developing lung cancer. In addition to moderate alcohol consumption, certain lifestyle changes can support lung health and mitigate the potential harm caused by alcohol.
This is an important difference, as the body responds differently to single versus repeated alcohol exposure. In rat liver cells and brain synaptosomes, alcohol has been found to inhibit mitochondrial respiration in a dose-dependent manner. First, drinks high in alcohol can trigger a gag reflex leading to aspiration of stomach contents. At these moderately high alcohol doses, oxygen saturation declined by up to 2-3% compared to sober levels. When alcohol is consumed, it acts as a central nervous system depressant that can slow down breathing. Alcohol’s effects on oxygen levels in the body is a complex topic with research showing mixed results.
In this manner, the epithelium of the conducting airways is continually exposed to ethanol during alcohol ingestion. Moreover, vaporized alcohol can deposit back into the airway lining fluid to be released again into the airways during exhalation. During alcohol ingestion, alcohol freely diffuses from the bronchial circulation directly through the ciliated epithelium where it vaporizes as it moves into the conducting airways (George et al., 1996). Clinicians and physiologists commonly believe that the alcohol present in exhaled air during alcohol consumption comes from alcohol that is vaporized from the alveolar-capillary interface of the pulmonary circulation. This review focuses on our current understanding of alcohol’s impact on airway functions based on clinical and experimental research. By virtue of their proximal location in lung airflow distribution, the conducting airways are the first interface of the lung with the outside environment.
