Your liver detoxifies and removes alcohol from your blood through 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. A good place to start to receive treatment for alcohol use is to talk to your healthcare provider. They may be able to give you prescriptions, provide referrals to therapists, or talk to you about treatment programs.
- Moreover, a recent systematic comparison examining gene expression changes found that temporal gene response patterns to trauma, burns, and endotoxemia in mouse models correlated poorly with the human conditions (Seok, Warren et al. 2013).
- So lemon water doesn’t just taste fancy and delicious—it also may help protect against alcohol-induced liver injury, at least according to one study conducted on animals (4).
- 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.
- Pancreatitis can activate the release of pancreatic digestive enzymes and cause abdominal pain.
- Long-term alcohol use can change your brain’s wiring in much more significant ways.

- It is also critical to take into consideration that the effects of ethanol on immune function in vivo could involve the actions of its primary metabolite, acetaldehyde.
- IL-10 blocks the activation of TNFα and complement, thus reducing expression of pro-inflammatory pathways; but it also checks expression of IL-6, thus limiting liver regeneration afforded by IL-6–induced upregulation of expression of liver-protective genes (Gao 2012).
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.
- A subset of cytokines, the chemokines, recruit immune cells, such as neutrophils and lymphocytes, to sites of injury or infection; thus, chemokines are often involved in pro-inflammatory signaling pathways.
- This has led to the proposition that combining the use of IL-22 with anti-inflammatory corticosteroids and TNFα inhibitors could offset the immunosuppressing effects of these two agents and promote recovery of liver tissues (Gao 2012).
- 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.
- But prolonged alcohol abuse can lead to chronic (long-term) pancreatitis, which can be severe.

The immune system is typically categorized into the innate and adaptive immune response systems, both of which are essential components in the body’s defense against pathogens. “By damaging those cells in your intestines, it can make it easier for pathogens to cross into your bloodstream,” says Nate Favini, MD, medical lead at Forward, a preventive primary care practice. That is, by drinking too much, you decrease your body’s defensive mechanisms to fight off a cold, virus, does alcohol weaken your immune system or other bacterial or viral infections. Studies in animals and in human cells lines have demonstrated that alcohol and LPS increase the expression of microRNA-34a, which helps alleviate alcohol-induced apoptosis in hepatocytes and biliary epithelial cells by targeting caspase 2 and sirtuin 1. The elevated expression of miRNA-34a is the result of an alcohol-induced decrease in methylation (i.e., hypomethylation) at a CpG island in the miRNA-34a promoter (Meng et al. 2012).
Alcohol’s physical effects on the body
According to the National Institute on Alcohol Abuse and Alcoholism (NIAAA), moderate drinking is defined as no more than four alcoholic drinks on any single day for men and no more than 14 in total over a week. For women, this reduces to three drinks on any single day and no more than seven drinks over a week. The monkeys classed as heavy drinkers showed diminished responses to the vaccine, compared with the monkeys that consumed sugar water. But the investigators were surprised to find https://ecosoberhouse.com/ that the monkeys deemed as moderate drinkers demonstrated an enhanced vaccine response. So lemon water doesn’t just taste fancy and delicious—it also may help protect against alcohol-induced liver injury, at least according to one study conducted on animals (4). “Your body’s response to alcohol can also be influenced by factors such as the health of your gut and liver, your hydration status, the quality of your sleep over the past week, the type of alcohol and the amount,” Jandes says.
- Alcohol’s metabolism generates an overabundance of the metabolic intermediate nicotinamide adenine dinucleotide in its reduced form (NADH), which stimulates the synthesis of excess fatty acids in the liver (Lieber 2004).
- This defect was rescued when cultures were treated with the Rho kinase inhibitor, Y27632 indicative that ethanol reduced efferocytosis through the induction of Rho kinase activity in a dose-dependent manner (Boe, Richens et al. 2010).
- DCs uptake antigens in peripheral tissues which leads to their maturation, and then travel to draining lymph nodes where they present them to T cells (Janeway 2008).
- Costly requirements such as dedicated facilities to house the animals, experienced personnel to perform specialized procedures, and compliance with high standards of care must be considered.
- Alcohol generates free radicals, which are unstable molecules that can cause oxidative stress and damage cells.
- These may include infections after surgery, traumatic injury, or burns; accelerated progression of HIV disease; adult respiratory distress syndrome and other opportunistic lung infections; and infection with hepatitis C virus, cirrhosis, or liver cancer (hepatocellular carcinoma).
