The main message McCullough and the American Cancer Society aim to share is that for lung cancer prevention, it’s best not to smoke. Despite the many screening methods, “there are lots of things that aren’t easily detected,” McCullough says. So in addition to avoiding tobacco, you should also curb your alcohol intake to be safe. Researchers are looking into alcohol’s possible role in causing or speeding the progress of cancers, says Kathy Jung, PhD, who directs the Division of Metabolism and Health Effects at the National Institute on Alcohol Abuse and Alcoholism. Although they haven’t found any clear answers, there’s broad evidence that drinking too much raises inflammation throughout the body as well as in separate tissues.
Acute Respiratory Distress Syndrome (ARDS)
Although alcohol consumption is socially accepted across many cultures, heavy and prolonged alcohol intake can lead not only to physical dependence but also to devastating long-term health problems. An estimated 18 million Americans have alcohol use disorder (AUD), including alcoholism and harmful drinking (National Institute on Alcohol Abuse and Alcoholism [NIAAA] 2014). NIAAA (2014) has established guidelines for low-risk drinking that are age and gender specific.
For example, Bouchard and colleagues (2012) showed that alcohol exposure triggered asthma-like pulmonary inflammation in an allergen-sensitized mouse model. The alcohol-exposed mice exhibited increased numbers of certain inflammatory cells (i.e., eosinophils) in fluid obtained from the lungs (i.e., bronchoalveolar lavage fluid), increased production of the main component of mucus (i.e., mucin), and constriction of the small airways (i.e., decreased bronchiole patency). These effects were not seen in mice that were exposed to alcohol but were not allergen sensitized, suggesting that alcohol can be an important trigger for airway reactivity in the context of an underlying allergic component. In contrast, Oldenburg and colleagues (2012) demonstrated that alcohol actually reduced airway hyperresponsiveness and airway inflammation in a mouse model of allergic asthma.
Acute Lung Injury
Acute respiratory distress syndrome (ARDS) is a severe type of lung injury that in many cases can be deadly. The most common causes include a buildup of fluid in the lungs, severe pneumonia, or another major injury. Pneumonia is an infection in the lungs caused by the spread of bacteria or viruses.
Effects of alcohol on the lungs
Activation of this dual kinase signaling pathway results in faster cilia beat frequency (CBF) in cilia briefly exposed to a moderate alcohol dose compared with controls (Sisson 1995; Sisson et al. 2009; Stout et al. 2007; Wyatt et al. 2003). More recent studies demonstrated that this rapid and transient alcohol-induced increase in NO levels was triggered by the alcohol-induced phosphorylation of heat shock protein 90 (HSP90) (Simet et al. 2013b). Upon phosphorylation, HSP90 increases its association with endothelial nitric oxide synthase (eNOS) in cilia, which then activates the cyclase–kinase cascade, resulting in increased CBF (Simet et al. 2013b).
- Taken together, these alcohol-mediated defects in alveolar macrophage function contribute to increased vulnerability to pulmonary infections.
- Additional studies revealed that alcohol causes a concurrent, and perhaps compensatory, increase in salt and water transport across the epithelium.
- For over a century, alcohol abuse has been well recognized as a significant risk factor for serious pulmonary infections.
- Alveolar macrophages in alcohol-exposed animals also exhibit decreased production of important chemokines and mediators, which impairs their ability to recruit other cell types, namely neutrophils, during times of stress and infection (Happel et al. 2004).
- Chronic alcohol ingestion decreases alveolar macrophage function by inhibiting the release of cytokines and chemokines as well as other factors essential for microbial killing and immune response (Franke-Ullmann et al. 1996; Omidvari et al. 1998).

Aspiration events are compounded by pathologic changes in the oropharyngeal flora caused how to flush alcohol out of your system quickly by alcohol abuse. Pneumoniae may be as much as four times higher in alcoholic compared with nonalcoholic patients (Fuxench-Lopez and Ramierz-Ronda 1978). This increased colonization by pathogenic organisms, combined with the acute intoxicating effects of alcohol and the subsequent depression of the normally protective gag and cough reflexes, leads to more frequent and severe pneumonias from gram-negative organisms. In parallel, defects in the function of the upper airway’s clearance mechanisms in alcoholic patients also play a role.
How Do You Treat Alcohol-Related Lung Damage?
An early experimental study in sheep investigating the effects of alcohol on ciliary beat frequency (CBF) demonstrated a dose-dependent effect, such that low alcohol concentrations actually stimulated CBF, whereas high concentrations impaired it (Maurer and Liebman 1988). Later mechanistic studies found that whereas short-term alcohol exposure causes a transient increase in CBF, chronic exposure desensitizes the cilia so that they cannot respond to stimulation (Wyatt et al. 2004). Alcohol-induced failure of the mucociliary system could interfere with the clearance of pathogens from the airways and thereby may contribute to the increased risk of pulmonary infections in people with chronic heavy alcohol use (Sisson 2007).
One way heavy drinking does this is by altering the airways over time, which can disrupt the inhalation process, decrease saliva production, and increase the risk for bacteria in the mouth. Alcohol misuse — heavy daily drinking or binge drinking, which is drinking a lot in a short time — in general can harm healthy lungs, Jung says. People with alcohol use disorder, defined as problem drinking that’s become severe, are more likely to get lung infections or diseases such as pneumonia, tuberculosis, and other serious respiratory problems. In addition to increasing the risk for developing ARDS, alcohol abuse also makes it more likely that an individual will develop a critical illness that puts them at risk for ARDS in the first place.
This cellular damage can predispose you to serious lung diseases if you are exposed to tobacco smoke, air pollution, dangerous chemicals, or other airway irritants. Lung issues are often the result of heavy or chronic alcohol use and cannot be reversed with a quick fix. Although there are several treatment strategies being researched for alcoholic lung damage, the most effective way to prevent further lung damage is to stop drinking. The sections below examine the epidemiology of alcohol prednisone can you drink alcohol abuse and pneumonia and the potential mechanisms by which alcohol abuse increases the risk for pneumonia.
However, there have been no systems biological approaches to the study of the alcoholic lung to date. 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. In parallel, efforts to study complex diseases such as acute lung injury and pneumonia using a genomics and/or proteomics approach, which involves the study of an organism’s genes and/or proteins, still are in their infancy. However, the alcoholic lung represents a clear example of environment–host interactions that should be well suited for such applications. The depletion of glutathione within the alveolar space of people with AUD explains many of the alcohol-related defects in the function of the alveolar epithelium as well as in the function of immune cells called macrophages (which will be discussed in the next section).
Your mucus-clearing ability can be impaired by excessive alcohol use as well, as the cilia in your lungs that help clear mucus and infectious organisms can be harmed. The top recommendation for treating alcohol use and its medical complications is to enter an inpatient rehab program. Inpatient treatment centers for alcohol commonly offer both medical detox services and rehabilitation programs for overcoming all aspects of a person’s addiction. Within a treatment setting, patients will have access to a medical doctor who can oversee their alcohol-related health problems and propose effective treatment options. According to research, pneumonia is more likely to be serious and even deadly in people who use alcohol. This is true even compared to people without a drinking problem that are hospitalized for their pneumonia.
Although RSV infections once were thought to be limited to children, it is now clear that RSV also is a serious problem in older people, patients with chronic obstructive pulmonary disease (COPD), and people with AUD. Prolonged alcohol maverick sober living exposure alters the first line of the innate cellular defense, the mucociliary apparatus, against invading pathogens such as RSV. This defense system propels inhaled particles, microbes, toxins, and debris out of the lungs and airways with the help of the fine hairs (i.e., cilia) on the cells that line the respiratory tract. Chronic alcohol use and heavy drinking can greatly increase the risk of several pulmonary conditions, including lung disease, alcoholic pneumonia, acute lung injury, and acute respiratory distress syndrome (ARDS). Seeking to verify that the relationship between alcohol intake and pulmonary glutathione deficiency in the rat were relevant for humans, Moss and colleagues (2000) measured lung glutathione levels in 19 otherwise healthy alcoholic subjects.
