Alcohol exposure, and particularly chronic heavy drinking, affects all components of the adaptive immune system. Studies both in humans and in animal models determined that chronic alcohol abuse reduces the number of peripheral T cells, disrupts the balance between different T-cell types, influences T-cell activation, impairs T-cell functioning, and promotes T-cell apoptosis. Chronic alcohol exposure also seems to cause loss of peripheral B cells, while simultaneously inducing increased production of immunoglobulins. In particular, the levels of antibodies against liver-specific autoantigens are increased in patients with alcoholic liver disease and may promote alcohol-related liver damage.
Alcohol, other drugs, and health: Current Evidence
- This impairment can lead to sepsis and pneumonia and also increases the incidence and extent of postoperative complications, including delay in wound closure.
- 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.
- Several studies have demonstrated the dose-dependent effect that alcohol has on preventing both monocytes and macrophages from binding to the bacterial cell wall component lipopolysaccharide (LPS).
- Indeed, in utero exposure to ethanol resulted in a significant reduction in T-cell and B-cell responses to various antigens that did not recover to control levels until 4 to 5 weeks of life.
Similarly, ONP cells isolated from newborn mice and cultured in vitro in the presence of 100 mM ethanol for 12 days failed to respond to IL-7 and commit to the B lineage, suggesting intrinsic defects (Wang et al. 2011). Additional investigations demonstrated that alcohol affects ONP cell differentiation into B lineage at a late stage by down-regulating the expression of several transcription factors (e.g., EBF and PAX5) and cytokine receptors, such as the IL-7 receptor (IL-7Ra) (Wang et al. 2009). Chronic heavy drinking isn’t the only way to damage your liver, often irreparably. Even acute alcohol consumption can overwork your liver and disrupt its finely tuned processes, leading to conditions like alcoholic cirrhosis.
What happens to your body if you drink alcohol every day?
- Their ability to serve as antigen presenting cells and produce cytokines in vivo has been controversial (Dong and Benveniste 2001).
- For instance, alcohol can damage the immune cells in the lungs, impairing their ability to clear pathogens from the airways.
- We’ll also highlight our commitment to transparency and quality at Cymbiotika, emphasizing our science-backed supplements that support immune health.
- The most surefire way to achieve success in recovery is to make and execute a well-thought-out plan, with the support of caring professionals.

This alcoholic liver disease typically starts as fatty liver disease and progresses to does alcohol lower immune system alcoholic hepatitis and, eventually, alcoholic liver cirrhosis. Chronic alcohol consumption, defined as drinking excessively over an extended period, can lead to more significant and lasting impairments in immune function. Studies indicate that heavy drinkers are more susceptible to pneumonia, tuberculosis, and other respiratory infections. Yes, alcohol can impair both innate and adaptive immune responses, making the body more susceptible to infections.
How alcohol affects the innate immune system
As we navigate this topic together, we invite you to reflect on your own alcohol consumption and consider how it fits into your overall wellness journey. For instance, studies indicate that consuming five to six drinks in a https://ecosoberhouse.com/ single session can suppress immune function for up to 24 hours. This temporary suppression can make us more vulnerable to infections, as our bodies struggle to combat pathogens during this period. Not only does the immune system mediate alcohol-related injury and illness, but a growing body of literature also indicates that immune signaling in the brain may contribute to alcohol use disorder.

- Without healthy gut bacteria, viruses and infections can worsen and develop into more severe complications.
- As we’ve explored, the connection between alcohol consumption and immune function is complex and significant.
- Drinking every day or drinking too much alcohol at a time may affect the immune system more than drinking every other day or every few days, but the healthiest thing to do is abstain from drinking completely.
- However, additional studies are needed to fully uncover the mechanisms that underlie increased Ig production while B-cell numbers are reduced.
- 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).
Alcohol also reduces sleep quality, which increases a person’s chances of getting Twelve-step program sick and recovering from illnesses. Adequate sleep helps the body fight off infections and viruses, and the less sleep you get, the less your immune system can protect your body. “The only remedy for an immune system damaged from drinking alcohol is to stop drinking. If you are not able to drink in moderation, you should avoid alcohol,” Dasgupta says.
