Alcohol and the Immune System PMC

A single episode of binge drinking can greatly reduce immune system function for up to 24 hours. In addition, it also adversely affects the body’s ability to heal itself from it. With a weakened immune system, one is far likelier to catch a viral or bacterial infection that might prove fatal under certain conditions. While alcohol is generally bad for your health, scientists are discovering the different ways in which alcohol and your immune system are closely linked. Consumption of alcohol can significantly weaken your immune system, making you more susceptible to various diseases and persistent health conditions.

• For example, one study found that women who consumed 330 mL of beer for 30 days exhibited a significant increase in leukocytes, mature CD3+ T-cells, neutrophils, and basophils.
• Therefore, symptoms may last longer and may become more intense than normal.

The heat from that extra blood passes right out of your body, causing your temperature to drop. On the other hand, long-term heavy drinking boosts your blood pressure. It makes your body release stress hormones that narrow blood vessels, so your heart has to pump harder to push blood through. The question is, how long does it take for your immune system to recover?

Bagby and colleagues review substantial evidence that alcohol further disrupts the immune system, significantly increasing the likelihood of HIV transmission and progression. Over time, heavy drinking makes the organ fatty and lets thicker, fibrous tissue build up. That limits blood flow, so liver cells don’t get what they need to survive.

When the immune system is down, it is at heightened risk for invasion of disease and infection. When our immune systems are not interrupted by harmful pathogens, bodily functions will run smoothly. However, when the body encounters pathogens that are aggressive or that it has not encountered before, it can weaken the immune system. This is when illness can happen in the form of infections or diseases. Women are typically more vulnerable to inflammatory and autoimmune diseases than men, and men have a higher risk of infections than women.

Impact on Hormones

Scientists have found that sulfites, antioxidant preservatives most often used as a food additive in alcoholic drinks, contribute to Alzheimer’s disease by making specific proteins damaged. Studies on lab rats have shown that alcohol impairs the hippocampus, which is the part of the brain responsible for learning and memory. Alcohol can also interfere with your body’s response to infection by inhibiting cytokines’ production.

Moreover, the wide-ranging roles of the immune system present significant challenges for designing interventions that target immune pathways without producing undesirable side effects. 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. There is evidence in a number of physiological systems that binge alcohol intake https://ecosoberhouse.com/article/blood-thinners-and-alcohol-risks-and-side-effects/ 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.

Through these programs, individuals can learn how to live life without relying on alcohol as a crutch. Regular meetings with a counselor or therapist can help keep individuals accountable and provide a safe space to talk about issues that may arise in recovery. There are lots of illnesses going around, and we are often stuck indoors—which can also mean excessive eating and drinking. You may be wondering if it is harmful to drink when you are feeling sick, and how much is too much. These days, many of us ask this question with alcohol and COVID-19 in mind.

The first point of contact for alcohol after consumption is the gastrointestinal (GI) system before it is absorbed into the bloodstream. Here, alcohol can damage the epithelial cells, T-cells, and neutrophils in the GI tract, all of which can alter the gut barrier function and allow intestinal microorganisms to leak into circulation. Although the innate immune response is immediate, it is not specific to any given pathogen. Some of the most notable contributors to the innate immune response include natural killer (NK) cells, neutrophils, monocytes, macrophages, and dendritic cells (DCs).

Bacterial and Viral Infections Linked to Drinking Alcohol

But unhealthy factors, like stress, smoking, or drinking alcohol, can be taxing for your immune system and make it harder for it to fight off infection. Past research shows alcohol consumption leads to more severe lung diseases, like adult respiratory distress syndrome (ARDS) and other pulmonary diseases, including pneumonia, tuberculosis, and respiratory syncytial virus. Getting help for alcohol abuse is not easy, but it can be life-changing.

• This can lead to other unpleasant effects and cause discomfort or medical problems.
• Alcohol can also interfere with your body’s response to infection by inhibiting cytokines’ production.
• Drinking alcohol to excess weakens your immune system and makes you more prone to COVID-19, and it also lengthens its duration.
• Animal studies find that alcohol consumption increases neuronal damage via the activation of immune factors.

By adhering to the Dietary Guidelines, you can reduce the risk of harm to yourself or others. This lack of inhibition can cause you to do things you wouldn’t do most of the time, thus putting your immune system at higher risk. In that case, you might develop severe liver problems and liver failure. In recent years, the use of alcohol breathalyzer devices has become more prevalent in testing an individual’s blood alcohol content (BAC).

Health

In cases where an individual has been drinking heavily over a long period of time, they will find that they are sick more often than their peers even if they are otherwise in better shape. You may have noticed that after a long period of excessive drinking, you catch colds more frequently. Alcohol can weaken your immunity to bacteria and viruses in several ways. Your liver is responsible for producing white blood cells that help fight infection.

If you also have hepatitis C (or any other kind of hepatitis), your liver is already working very hard to fight the disease itself and deal with the strong drugs that you may be taking for your hepatitis treatment. Other common recreational drugs, such as cocaine or crystal methamphetamine (“meth,” “speed”), can leave your body dehydrated and exhausted, as well as lead to skin irritation. You may be more likely to get serious does alcohol weaken your immune system lung infections, such as pneumonia. Here’s how alcohol affects your immune system – and why you may want to consider staying dry this winter to prevent getting sick. Winter is officially upon us – meaning that it’s now cold and flu season, on top of a global pandemic. As much as you may want to reach for a hot toddy or Irish coffee to help you stay warm, you may want to consider cutting back for your immune system’s sake.
