Alcohol & The Immune System: How Alcohol Can Lower Your Immune System


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 gastrointestinal (GI) system is typically the first point of contact for alcohol as it passes through the body and is where alcohol is absorbed into the bloodstream. One of the most significant immediate effects of alcohol is that it affects the structure and integrity of the GI tract. These organisms affect the maturation and function of the immune system. Alcohol disrupts communication between these organisms and the intestinal immune system. There are quite a few discrepancies concerning how alcohol affects the heart, how much is too much, and whether or not it directly leads to heart disease.

Like any addiction, seek the advice of a professional who can put a program in place for you to ensure the safest route to recovery. Suppose you understand you have an addictive personality and https://ecosoberhouse.com/ notice a clear pattern of increased consumption. Those who find themselves drinking to excess through circumstances such as working from home will be a more comfortable journey to sobriety.

These effects are worse if you practice binge drinking or heavy drinking over a period of a few days. The sudden volume of alcohol can shock the system and suppress the immune system function for some time. These powerful chemicals manage everything from your sex drive to how fast you digest food. For example, some studies suggest that moderate alcohol drinking can affect fertility for some women. Research also shows that heavy drinking by men may lower testosterone levels and affect the making of sperm.

Alcohol intoxication not only increases the risk of such injuries but can negatively affect outcomes for these patients. The complex interaction between alcohol, immunity, and disease is particularly relevant to HIV infection. HIV attacks the immune system by destroying a type of T cell vital to fighting infections. The destruction of these cells leaves people with HIV vulnerable to other infections, diseases, and complications. If you or a loved one has a drinking problem, it is vital to seek help.

Alcohol and the Immune System: What are the Symptoms to Look Out For?

Many people may not know about the damage that alcohol can do to the circulatory system; primarily the heart and lungs. This can cause increased production of acid as well as limit your ability to get rid of bacteria. At the same time, the lining of your stomach can be damaged by the acid it contains, causing abrasion and swelling.

  • Symptoms may also be mistaken for that of other respiratory illnesses such as tuberculosis or coeliac disease.
  • Alcohol’s widespread effects on immune function also are underscored in the article by Gauthier, which examines how in utero alcohol exposure interferes with the developing immune system in the fetus.
  • In that case, you might develop severe liver problems and liver failure.
  • Long-term sobriety provides health benefits that give the body time to heal and restore the different parts of the immune system.

Cytokines are a group of chemical messengers that affect the behavior of cells. In particular, the cytokine interleukin-21 promotes the inflammation of cells.

Drinking impairs immune cells in key organs

The mechanisms that may underlie these differences could be gender differences in the physiological processing and metabolic clearance of alcohol and differential sensitivity of the nervous system to alcohol. Furthermore, there is also evidence implicating the direct involvement of hormones in the gender differences observed regarding alcohol consumption. There is clearly a need for a better understanding of the biological mechanisms underlying gender differences in ethanol consumption. Prolonged alcohol consumption can weaken the body’s natural defense against diseases, putting heavy drinkers at risk of getting sick and perhaps staying sick. Alcohol in large amounts can be so harmful to the immune system that a person who indulges in excessive drinking could be just as much at risk of getting sick as someone who drinks regularly.

It appears as if moderate drinking (one or two drinks per day) isn’t too bad for the heart. However, some people should probably avoid drinking in its entirety due to risks such as heart failure. But even moderate alcohol consumption is thought to have some effect on the immune system and, potentially, on how your body handles any bacterial or viral infections you may face in the following days. That being said, there can alcohol weaken your immune system is a big difference between moderate drinking and excessive drinking in terms of its effects on your body and its immune system.

Moderate drinking is defined as up to one drink per day for people assigned female at birthday and up to two drinks per day for people assigned male at birth, per the NIAAA. Chronic drinkers are predisposed to a wide range of health problems, including infections and systemic inflammation, due to alcohol’s combined impact on both innate and adaptive immunity. The Centers for Disease Control and Prevention (CDC) considers “moderate drinking” to consist of one standard drink per day for women or two standard drinks per day for men.
