Understanding the impact of alcohol on the body’s immune system is important. Frequent and heavy alcohol consumption can suppress the immune system, making the body vulnerable to viruses and infections. Alcohol misuse can cause short-term effects such as the common cold or gastrointestinal complications, but it can also lead to more serious conditions such as cancer, septicemia, or, liver disease. In addition to pneumonia, alcohol consumption has been linked to pulmonary diseases, including tuberculosis, respiratory syncytial virus, and ARDS. Alcohol disrupts ciliary function in the upper airways, impairs the function of immune cells (i.e., alveolar macrophages and neutrophils), and weakens the barrier function of the epithelia in the lower airways (see the article by Simet and Sisson).
When to Get Help at Treatment Centres
Many people assume the occasional beer or glass of wine at mealtimes or special occasions doesn’t pose much cause for concern. But drinking any amount of alcohol can potentially lead to unwanted health consequences. “Those at increased risk should cut down or abstain from alcohol because every little thing an individual can do to improve the health and reduce risk is worth it at this point, even if the evidence is not entirely clear,” Mroszczyk-McDonald said.

- These molecules help recruit and activate additional PMNs as well as macrophages to the site of an injury or infection.
- Having blood cancer and getting COVID-19 raises the risk of death from the illness.
Modulation of Innate Immunity by Alcohol
A secondary lung abscess can develop from a lung obstruction or infection that begins in another body part. A lung abscess can lead to cough, chest pain, fever, fatigue, night sweats, appetite loss, weight loss, sputum, and, empyema. When alcohol damages the gastrointestinal tract’s barrier, bacteria and toxins can enter the bloodstream easily, potentially leading to septicemia and sepsis. Certain factors may increase your chances of experiencing alcohol use disorder. Alcohol withdrawal can be difficult and, in some cases, life threatening.
- Alcoholics Anonymous is available almost everywhere and provides a place to openly and nonjudgmentally discuss alcohol issues with others who have alcohol use disorder.
- Meanwhile, sugar-laden beverages suppress your immune system — particularly the white blood cells that attack harmful bacteria — for several hours, says Dr. Cherian.
- In addition to these changes in cytokine function, investigators also have shown a contribution of barrier dysfunction to the postinjury increase in infections in intoxicated people (Choudhry et al. 2004).
- Your body breaks alcohol down into a chemical called acetaldehyde, which damages your DNA.
- “Once your immune system has gone through this initial stimulation, it generates memory immune cells that have seen the enemy and are ready to go when they see the enemy again,” he continues.
- In contrast to the inhibitory effects of acute alcohol treatment (up to 24 hours), prolonged exposure of human (men and women) peripheral blood monocytes to 25mM ethanol for 7 days increased LPS-induced TNF-α production without affecting IL-10 production (Pang, Bala et al. 2011).
Get Plenty of Restorative Sleep
Impulsiveness, loss of coordination, and changes in mood can affect your judgment and behavior and contribute to more far-reaching effects, including accidents, injuries, and decisions you later regret. A lack of sleep can also affect how long it takes for a person to recover if they do get sick, according to the Mayo Clinic. When the body is unable to clear a pathogen, an infection can worsen and lead to more severe, life threatening complications. Alcohol has been flying off the shelves as people try to combat boredom during lockdown, with some reports estimating that alcoholic beverage sales surged by 55 percent toward the end of March. Cirrhosis, on the other hand, is irreversible and can lead to liver failure and liver cancer, even if you abstain from alcohol.
Hepatitis B and Hepatitis C
These complications can increase your susceptibility to illness,” says Vivek Cherian, MD, an internal medicine physician based in Baltimore, Maryland. Meanwhile, sugar-laden beverages suppress your immune system — particularly the white blood cells that attack harmful bacteria — for several hours, says Dr. Cherian. Biomedical consequences of alcohol-induced dysregulation of the immune system. The innate immune response orchestrated by all these components provides the first line of defense against invading pathogens and plays a key role in the activation and orientation of adaptive immunity, as well as in the maintenance of tissue integrity and repair. Only if a pathogen can evade the different components of this response (i.e., structural barriers as well as cell-mediated and humoral responses) does the infection become established and an adaptive immune response ensues.
Modulation of Adaptive Immunity by Alcohol
- Steatotic liver disease develops in about 90% of people who drink more than 1.5 to 2 ounces of alcohol per day.
- Heavy alcohol use weakens the immune system, and a weak immune system makes it easier to get sick.
- Pathways involving antigen presentation, B and T cell receptor signaling, and IL-15 signaling were altered with moderate vodka consumption (Joosten, van Erk et al. 2012).
- Septicemia is a serious condition because it can cause the bloodstream to carry bacteria and toxins throughout the entire body.
- Your healthcare team may suggest added doses of COVID-19 vaccine if you have a moderately or seriously weakened immune system.
- Dehydration-related effects, like nausea, headache, and dizziness, might not appear for a few hours, and they can also depend on what you drink, how much you drink, and if you also drink water.
Long-term alcohol misuse can weaken your immune system, making you more vulnerable to serious infections. It can also weaken your bones, placing you at greater risk of fracturing or breaking them. Stopping alcohol use can significantly improve your health, boost your immune system and protect your body from serious does alcohol weaken your immune system infections and viruses.
