Drinking too much alcohol can harm your health Learn the facts

In addition to a heightened likelihood of an autoimmune disorder, excessive alcohol consumption can cause a general instance of immune deficiency. An immune deficiency is a chronic impairment of the immune system’s functions, leading to an increased vulnerability to bacterial, viral, or fungal infections. Though this is different than an autoimmune disorder, it can be just as devastating and cause grave illness in sufferers. Continuous consumption of alcohol is likely to worsen symptoms and further debilitate the immune system’s strength. Alcoholic cirrhosis is a devastating consequence of continuous, excessive alcohol consumption. It is a late-stage disease of the liver that is caused by the formation of scar tissue that replaces previously healthy, functioning liver tissue.

  • Because alcohol cannot be stored the same way as macronutrients like carbohydrates, it must be sent directly to the liver, where it is metabolized immediately.
  • These should tide you over until you seek professional advice and also apply throughout recovery.
  • While moderate alcohol consumption may not have significant negative effects on immunity, excessive or chronic alcohol use can impair the body’s ability to defend against pathogens.
  • This can be difficult as alcohol has such heavy presence in social settings and as a coping mechanism to deal with stressful situations.
  • Excessive drinking can damage the bone marrow, where white blood cells are produced.
  • “Alcohol artificially increases GABA levels, a neurotransmitter that slowly rises throughout the day and is at its peak when it’s time to sleep,” Moorcroft says.

There is evidence in a number of physiological systems that binge alcohol intake complicates recovery from physical trauma (see the article by Hammer and colleagues). Molina and colleagues review research showing that alcohol impairs recovery from three types of physical trauma—burn, hemorrhagic shock, and traumatic brain injury—by affecting immune homeostasis. Their article also highlights how the combined effect of alcohol and injury causes greater disruption to immune function than either challenge alone. Not only are chronic drinkers more likely to develop many of these illnesses, but in some cases, they are also more likely to die as a result. For example, in the case of pneumonia, the body’s natural response to the first sign of this infection is to deploy neutrophils, cells that fight bacteria-induced inflammation. Multiple studies have confirmed that alcohol impairs the body’s neutrophil response, making it difficult to fight off pneumonia and heightening the risk of death as a result.

In severe cases, hypoxia can be fatal, and alcohol can be a particularly dangerous substance due to the ethanol that is contained in all alcoholic drinks. Research shows that the combination of alcohol and ethanol can inflict a greater degree of damage to cells in persons experiencing hypoxia. “Alcohol also does alcohol weaken your immune system destroys the protective lining inside your respiratory tract that your immune system uses to prevent upper respiratory tract infections like the common cold,” Dasgupta says. Lung conditions linked to alcohol include pneumonia, tuberculosis and acute respiratory distress syndrome, according to the NIAAA.

Therefore, further studies focused on drinking pattern are necessary to elucidate the effect of moderate alcohol consumption on the immune response. Alcohol alters the makeup of your gut microbiome — home to trillions of microorganisms performing several crucial roles for your health — and affects those microorganisms’ ability to support your immune system. It seems that drinking alcohol may also damage the immune cells that line the intestines and serve as the first line of defense against bacteria and viruses. Alcohol consumption does not have to be chronic to have negative health consequences. In fact, research shows that acute binge drinking also affects the immune system.

Q: Should I avoid alcohol altogether?

It consists of several different types of white blood cells and proteins and some other components that protect you from harmful infections, such as COVID-19. 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. The effects of alcohol on both cell-mediated and humoral immunity have been well-documented since the early 1960s, wherein researchers found that alcohol abuse significantly reduced both CD4 and CD8 T-cell counts. The study revealed that a diagnosis of each of these autoimmune disorders is more likely once a person has been diagnosed with alcoholic cirrhosis. Though this may not confirm an explicitly causal relationship, it does confirm that excessive alcohol consumption makes you more vulnerable to the development of an autoimmune disorder. In this article, we’ll explore how drinking can affect the immune system, how long it can take for your immune system to heal from excessive drinking and how alcohol addiction treatment can help.
