What Does Alcohol Do to Your Body?

Alcoholic drinks containing antioxidants may cause less damage than other drinks because they help protect against some of the free radicals in ethanol. While any alcoholic drink can have negative effects on the body, beers or wines that contain vitamins, antioxidants and polyphenols may cause less damage to the immune system than heavy liquors. Several studies have also shown that the lungs are highly vulnerable to the effects of alcohol. For example, alcohol can reduce the ability of respiratory epithelium cells to remove mucous from the lungs, which can directly damage lung tissue and weaken the proper functioning of the lungs over time.

This exposure increases a newborn’s risk of infection and disease; additional evidence suggests that alcohol’s deleterious effects on immune development last into adulthood. The intestine contains microorganisms that help maintain a healthy immune system, reduce the risk of infection and help the gastrointestinal tract function normally. Alcohol intake kills this bacteria, hindering the body’s can i drink alcohol with cymbalta ability to clear pathogens. Without healthy gut bacteria, viruses and infections can worsen and develop into more severe complications. Alcohol also damages T cells, neutrophils, and epithelial cells, which disrupts the gut barrier’s function. In addition to pneumonia, alcohol consumption has been linked to pulmonary diseases, including tuberculosis, respiratory syncytial virus, and ARDS.

Moderate alcohol use may not weaken the immune system, but you should be careful

If you drink twice or week or less and only drink two to three drinks per occasion, your immune system may not be at a high risk of damage. If you find it challenging to limit or stop your alcohol intake, it may be time to seek help for alcohol addiction. Heavy drinking is more likely to affect a person’s immune system than moderate drinking. Women drinking fewer than two drinks at a time and men drinking fewer than three drinks at a time is considered moderate drinking.

  1. Much progress has been made in elucidating the relationship between alcohol consumption and immune function and how this interaction affects human health.
  2. Over time, heavy drinking can reduce a liver’s regenerative abilities and lead to alcoholic liver disease (ALD).
  3. After binding to LPS, monocytes are activated and mature into macrophages that travel to the site of infection to secrete important cytokines for the inflammatory response.
  4. Stopping alcohol use can significantly improve your health, boost your immune system and protect your body from serious infections and viruses.
  5. Infection with viral hepatitis accelerates the progression of ALD, and end-stage liver disease from viral hepatitis, together with ALD, is the main reason for liver transplantations in the United States.

The morning after a night of over-imbibing can cause some temporary effects on your brain. Things like trouble concentration, slow reflexes and sensitivity to bright lights and loud sounds are standard signs of a hangover, and evidence of alcohol’s effects on your brain. That’s because your body already has processes in place that allow it to store excess proteins, carbohydrates and fats.

Alcohol Use As a Risk Factor in Infections and Healing: A Clinician’s Perspective

But when you ingest too much alcohol for your liver to process in a timely manner, a buildup of toxic substances begins to take a toll on your liver. Your liver detoxifies and removes alcohol from your blood through the textures of heroin a process known as oxidation. When your liver finishes that process, alcohol gets turned into water and carbon dioxide. Dr. Sengupta shares some of the not-so-obvious effects that alcohol has on your body.

Soon after, the World Health Organization (WHO) also suggested that people cut back on drinking, since alcohol can increase the risk of experiencing complications from COVID-19. “When you’re feeling run down or like you might get sick, you want to be well hydrated so that all the cells in your body have enough fluid in them and can work really well,” Favini says. But there’s plenty of research to back up the notion that alcohol does lead to weight gain in general. The adaptive immune system can be further subdivided into cell-mediated immunity and humoral immunity. Whereas T-cells are primarily involved with cell-mediated immunity, B-cells play a major role in humoral immunity.

Significant differences between the immune system of the mouse—the primary model organism used in immune studies—and that of humans also complicate the translation of experimental results from these animals to humans. Moreover, the wide-ranging roles of the immune system present significant challenges for designing interventions that target immune pathways without producing undesirable side effects. In a clinical case study reviewed in this issue, Trevejo-Nunez and colleagues report on systemic and organ-specific immune pathologies often seen in chronic drinkers. In such patients, alcohol impairs mucosal immunity in the gut and lower respiratory system.

How alcohol impacts the gut

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. 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. As soon as you drink a sip of alcohol, your body begins to prioritize breaking down alcohol.

Alcohol consumption and infection

A weakened immune system increases an individual’s chances of developing empyema. It causes pus to accumulate in the respiratory system’s pleural cavity, the space between the chest cavity’s inner wall surface and the lungs. Since pneumonia is an infection inside the lung, a person can gradually cough it out.

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. For example, alcohol alters the numbers and relative abundances of microbes in the gut microbiome (see the article by Engen and colleagues), an extensive community of microorganisms in the intestine that aid in normal gut function. Alcohol disrupts communication between these organisms and the intestinal immune system. Alcohol consumption also damages epithelial cells, T cells, and neutrophils in the GI system, disrupting gut barrier function and facilitating leakage of microbes into the circulation (see the article by Hammer and colleagues). Clinicians have long observed an association between excessive alcohol consumption and adverse immune-related health effects such as susceptibility to pneumonia.

How much alcohol you have to drink before it weakens your immune system

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, alcohol and seizures can alcohol or withdrawal trigger a seizure monocytes, macrophages, and dendritic cells (DCs). This condition occurs when bacteria enter the chest cavity’s pleural space, typically due to pneumonia or a post-surgery infection.

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. Alcohol also reduces sleep quality, which increases a person’s chances of getting sick and recovering from illnesses. Adequate sleep helps the body fight off infections and viruses, and the less sleep you get, the less your immune system can protect your body.

Empyema occurs outside of the lungs, so doctors must remove it via surgery or by draining it with a needle. Those who have any of the known risk factors for COVID-19, like heart disease or diabetes, should drink even less. Your gut microbiome is a hotbed of bacteria that help keep your digestive system happy and healthy. The trillions of microbes in your colon and large and small intestines are critical to proper digestion. “Some people think of the effects of alcohol as only something to be worried about if you’re living with alcohol use disorder, which was formerly called alcoholism,” Dr. Sengupta says.

A lung abscess can lead to cough, chest pain, fever, fatigue, night sweats, appetite loss, weight loss, sputum, and, empyema. That said, evidence also shows that even smaller amounts of alcohol can affect the immune system. One study found that people who got less than 7 hours of sleep were nearly three times more likely to develop a cold compared with those who got 8 or more hours of sleep. Similarly, alcohol can trigger inflammation in the gut and destroy the microorganisms that live in the intestine and maintain immune system health.
