Alcohol consumption, even short-term alcohol misuse, can have devastating effects on almost every single organ and system of the user, including the immune system.
In 2015, the National Institute on Alcohol Abuse and Alcoholism (NIAAA) recognized the devastating effects of alcohol on the immune system and issued a warning about the link between immune system problems and alcohol consumption. A series of articles on the destructive consequences of alcohol misuse and dependence on people’s immune system was published in the journal Alcohol Research: Current Reviews.
People with alcohol use disorders are more vulnerable to significant health problems like certain cancers and diseases due to the strain caused on the body’s immune system. Alcohol not only interferes with a person’s ability to fight off bacterial and viral infections, it also contributes to immunosuppression and tissue damage due to inflammation and cancer.
Our body’s immune system plays a critical role in keeping us alive and healthy by fighting off diseases, parasites, bacteria and viruses. Over time, chronic and excessive alcohol use can contribute to immune system difficulties, including greater abnormalities in the levels of:
Dysregulation in the levels of these important specialized cells in the bloodstream and throughout the body can greatly impair the body’s ability to fight off diseases and increase a person’s susceptibility to a host of infections and other health problems.
The figure given below shows the distribution of these cells that reside in the primary and secondary lymphoid organs.

Alcohol can have a broad range of devastating consequences on the immune system, making it unable to fight off an array of infectious diseases, says Patricia E. Molina, M.D., Ph.D., a professor and department head of physiology, and her colleagues, at the Louisiana State University Health Sciences Center in New Orleans, Louisiana, and other researchers.
As a result, excessive alcohol consumption can lead to following problems:
Alcohol use disorders can be deadly and people should be aware of the toxic effects of alcohol on the body. Damage to the immune system can be serious and even deadly.
