But as you drink more — and you don’t need to drink that much more — eventually, the enzymes that break down the alcohol get saturated. So, the alcohol builds up quite quickly,” explains addiction psychiatrist Akhil Anand, MD. Many different supplements, including multivitamins, are available to purchase in health stores or online. The CDC recommend a vaccination schedule that most people should try to follow. However, people with a weak immune system should check with a doctor which vaccines are safe for them to have and then follow the doctor’s recommendations.
How Does Alcohol Affect Your Immune System?
It is also critical to take into consideration that the effects of ethanol on immune function in vivo could involve the actions of its primary metabolite, acetaldehyde. Therefore, more studies looking at the effects of ethanol metabolites in vivo are needed. Acetaldehyde has also been shown to affect NFκB-induced cytokine production in various liver cells. Finally, acetaldehyde disrupts intestinal epithelial barrier function and increases paracellular permeability which plays a crucial role in the pathogenesis of alcoholic liver disease by a tyrosine kinase-dependent mechanism (Sheth, Seth et al. 2004). Male rats on a liquid diet with 35% of calories coming from ethanol also showed enhanced mRNA half-life and protein expression of LPS-induced TNF-α by increasing TNF-α in liver monocytes/macrophages (Kishore, McMullen et al. 2001). Dendritic cells also are mononuclear phagocytes derived from monocytes.

These antibodies attack invaders and prevent an infection from spreading further. Your immune system has several different cell types, each of which has a different but very important job to help keep you healthy. Alcohol gets in the way of these immune cells being able to do their jobs. Examples include certain cancers, as well as pneumonia and other respiratory problems.
Liver failure
“Alcohol has diverse adverse effects throughout the body, including on all cells of the immune system, that lead to increased risk of serious infections,” said Dr. E. Jennifer Edelman, a Yale Medicine addiction medicine specialist. Chronic drinking — for 12 to 15 years — can lead to a reduction in the number of T cells. Extremely heavy drinking — about 30 drinks per day — can throw off the balance of immune system cells. The risk of serious COVID-19 illness also is higher for people who have conditions that damage lung tissue over time.
The risk of serious COVID-19 illness is linked to having one or more underlying medical condition. The risk for serious COVID-19 illness depends on your health status, age and activities. This includes where you live, work or learn, how easy it is for you to get medical care, and your economic stability. While alcohol is a relaxant and can make you feel good at first, chronic alcohol use can cause mental health issues. And if you have one too many alcoholic drinks, you may start to slur your speech and have trouble walking in a straight line — and that’s all before dealing with a hangover the next day. For example, a person who has a vitamin C deficiency can have weakened immunity.
- Your body releases certain proteins that help the immune system, called cytokines, only during sleep.
- Alcohol consumption does not have to be chronic to have negative health consequences.
- “Alcohol has diverse adverse effects throughout the body, including on all cells of the immune system, that lead to increased risk of serious infections,” said Dr. E. Jennifer Edelman, a Yale Medicine addiction medicine specialist.
- The ability of alcohol to alter both innate and adaptive immune defenses inevitably impacts how the immune system of even a moderate alcohol drinker can respond to infections.
- In addition, chronic alcohol can decrease the number of B-cells that produce an antibody type called IgA5 in one of the layers of mucous membranes (i.e., the lamina propria), which is indicative of altered mucosal immunity (Lopez et al. 1994).

Individuals with AUD are often deficient in one or more essential nutrients including vitamin A, vitamin C, vitamin D, vitamin E, folate, and thiamine (Hoyumpa 1986). These micronutrients have been shown to play an important role in immune system homeostasis and response to infection (Mora, Iwata et al. 2008). Alcohol’s effect on the immune system can also affect cancer recovery. Having a fully functioning immune system is crucial to successful chemotherapy treatment, so a person’s body may not handle or react to conventional chemotherapy as well if they drink alcohol. Alcohol consumption can allow the hepatitis virus to persist as a chronic condition, and alcohol use disorder combined with hepatitis often accelerates liver disease progression. Alcohol also reduces sleep quality, which increases a person’s chances of getting sick and recovering from illnesses.
Finding treatment for alcohol use disorder
- Sunlight may energize special cells in your immune system called T-cells that help fight infection.
- Specifically, 24 hours of exposure to both low (1mM) and high (5mM) concentrations of acetaldehyde stimulate IL-6 secretion, however, 7 days of exposure to the high concentration of acetaldehyde, significantly decrease IL-6 secretion (Sarc, Wraber et al. 2011).
- Szabo says that the results fit with evidence from medical records that chronic heavy drinkers with HIV die sooner than non-drinkers.
