Pure ethanol is a moderately effective and transient bronchodilator and likely relaxes airway smooth muscle tone. The mechanisms responsible for alcohol-induced relaxation of airways are poorly understood and may include receptor-and non receptor-mediated signal transduction pathways involving calcium and/or nitric oxide as second messengers. Many non-alcohol components of alcoholic beverages likely act as triggers for asthma in sensitized individuals and as such are not different from other asthma triggers. Acetaldehyde, the primary metabolite of ethanol, can trigger bronchoconstriction in asthmatics with genetically reduced ALDH2 activity and represents a significant trigger for asthma in certain Asian populations.
Can Smoking and Drinking Affect COPD?
Over time, this can start to affect the lungs, making the body more vulnerable to lung infections and damage. Alcohol (pure ethanol), in the absence of any metabolites or congeners, relaxes airway smooth muscle tone resulting in bronchodilated airways. Non-alcohol congeners, often present in alcoholic beverages, can cause contraction of airway smooth muscle resulting in bronchoconstricted airways in some sensitized or allergic individuals.
Clinical Studies of Alcohol and Asthma
Thus, although the total number of circulating B cells does not differ significantly between people with and without AUD, people with AUD have elevated levels of circulating IgA, IgM, and IgG (Spinozzi et al. 1992). In the lungs of people with AUD, however, Ig levels are reduced as determined by bronchoalveolar lavage (BAL) (Spinozzi et al. 1992). Replacement IgG therapy only partially restored Ig levels in these people, although it decreased the rates of pulmonary infections (Spinozzi et al. 1992).

Such common clinical observations likely prompted George Burch to write a provocative editorial in 1967 in the American Heart Journal entitled “Alcoholic lung disease-An hypothesis” (Burch and DePasquale, 1967). In this editorial he made a cogent case for the lung being a prime candidate for alcohol-induced tissue injury. He asserted that this is due to the lung’s delicate structure and its exposure to the entire cardiac output containing alcohol that has escaped first pass metabolism in the liver. Although we have ketamine detox symptoms timeline medications and treatment not yet conclusively proven Burch’s hypothesis, there is growing evidence that alcohol plays a role in the pathogenesis of COPD. Boyd reported that inhaled alcohol, in a dose-dependent manner, augmented the volume and mucus content from the lungs of anesthetized rabbits at very high doses (5 ml/kg) of inhaled alcohol (Boyd and Sheppard, 1969). Using the frog palate model, Leitch found that high concentrations of alcohol (3–5% or 0.6–1.1 M) depressed both mucus clearance and secretion (Leitch et al., 1985).
Alcohol has unique effects on the ciliated airways because it is rapidly and transiently absorbed from the bronchial circulation directly across the ciliated epithelium of the conducting airways. However, when the exhaled air cools as it reaches the trachea, the alcohol vapor condenses and is dissolved back into the fluid in periciliary airway lining (George et al. 1996). Excessive alcohol consumption can weaken a person’s immune system, increasing their susceptibility to lung conditions, such as pneumonia, syncytial respiratory virus, and acute respiratory distress syndrome. Acetaldehyde is produced by the metabolism of ethanol through the action of alcohol dehydrogenases. Acetaldehyde has long been recognized as a trigger for asthma in Asians and is referred to as “alcohol-induced bronchial asthma” (Shimoda et al., 1996).
The most susceptible individuals are Asians who have greatly reduced function of the enzyme aldehyde dehydrogenase isoform 2 (ALDH 2) and can be identified through genetic testing and/or ethanol challenge testing (Matsuse et al., 2001). About half of Japanese have inadequate ALDH2 activity and cannot effectively metabolize acetaldehyde. effects of meth on the body what does meth do to your body This results in facial flushing, wheezing and other undesirable side effects following the ingestion of modest amounts of alcohol (Gong et al., 1981). Bronchospasm following alcohol ingestion is well described in asthmatics of Japanese descent (Watanabe, 1991) and is closely linked to the ALDH2 genotype (Shimoda et al., 1996).
- This decreased neutrophil proliferation may account for the decreased number of neutrophils found in the lungs during the host response to pneumonia following alcohol consumption.
- Proposed pathophysiological sequence by which alcohol abuse renders the lung susceptible during acute inflammatory stresses such as infection (i.e., sepsis) and trauma.
- Individuals with COPD typically have, to varying degrees, elements of asthma, bronchitis and emphysema.
- The cilia in your lungs can be damaged by heavy alcohol abuse, potentially causing more mucus to stay in your lungs.
Another fatal association between alcohol abuse and pneumonia was identified in a retrospective review of patients admitted with pneumococcal bacteremia that examined a subset with alcoholism and low white blood cell count (i.e., leukopenia) (Perlino and Rimland 1985). Ninety-three patients with pneumococcal bacteremia were identified, 12 of whom had a history of alcohol abuse and a white blood cell count of less than 4,000 cells per cubic millimeter (mm3) of blood. Ten of these 12 (83.3 percent) patients died, whereas the mortality in the rest of the cohort was only 22 percent. Overall, these and other studies demonstrate the association between alcohol abuse and community-acquired pneumonia, an association that results in more severe infections and higher mortality.
A person with any of these risk factors needs to consider them when deciding whether to also drink alcohol. This rare genetic disorder reduces the body’s ability to protect the lungs, ecstasy withdrawal and detox symptoms and timelines which makes a person more prone to develop COPD. Research also suggests that alcohol could cause breathing problems by negatively impacting the healthy function of the lungs.
In order to best avoid developing COPD, it’s important to avoid heavy alcohol consumption and to quit smoking if you’re currently a smoker. Heavy drinking can reduce your levels of glutathione, which is an antioxidant that helps protect your lungs. A study published in the Journal of General Internal Medicine found that a third of adults with chronic health problems such as COPD drank regularly; 7% said they drank heavily. And while a 2016 study in Oxford Academic reported that people diagnosed with a medical condition, such as cancer, often quit drinking upon beginning treatment, that same study reported that people diagnosed with diseases such as COPD aren’t as likely to quit. In the vast majority of people with COPD, the lung damage that leads to COPD is caused by long-term cigarette smoking. But there are likely other factors at play in the development of COPD, such as a genetic susceptibility to the disease, because not all smokers develop COPD.
