Moderate drinkers had three times the does alcohol kill kidneys risk of shrinkage than nondrinkers. And prolonged alcohol use can lead to mental health conditions like anxiety and depression. The morning after a night of over-imbibing can cause some temporary effects on your brain.

Also, activated Kupffer cells secrete pro-inflammatory cytokines, linking apoptosis in the liver to inflammation 112. When ALD is established, an accumulation of reducing equivalents in the cytosol and the rates of fatty acids biosynthesis and subsequent esterification into triglycerols are increased 113. It is also possible to observe massive hepatocyte apoptosis, which induces progressive fibrosis, and could result in liver failure, cirrhosis, and hepatocellular carcinoma 111. Alcohol doesn’t kill brain cells, but it does have both short- and long-term effects on your brain, even in moderate amounts. Going out for happy hour a few nights a month likely won’t cause any long-term damage. But if you find yourself drinking heavily or binge drinking often, consider reaching out for help.
Got Memory Issues? Here’s How To Tell If It’s Dementia Or Just Aging
But there’s plenty of research to back up the notion that alcohol does lead to weight gain in general. If alcohol continues to accumulate in your system, it can destroy cells and, eventually, damage your organs. But when you ingest too much alcohol for Substance abuse your liver to process in a timely manner, a buildup of toxic substances begins to take a toll on your liver.
Cancer risk
Extensive MPT leads to mitochondria swelling as a result of the influx of ions and water, and permits the cytochrome c release 74, leading to caspases activation 75 and DNA fragmentation, which are key events for induction of programmed cell death or apoptosis 74. Bailey 38 showed that there is a decrease in several antioxidant mechanisms in liver caused by increased ROS and RNA levels during chronic alcohol exposure. Early studies have shown that a decrease in the liver content or reduced GSH is a common feature in ethanol-fed animals as well as in patients with alcoholism 43. Chronic alcohol intake lowers the mitochondrial GSH (mtGSH) 69, which makes these organelles more susceptible to oxidative damage, and precedes the development of mitochondrial dysfunctions, such as lipid peroxidation 69, and the impairment of ATP synthesis 70. Brain mitochondria appear to be the principal targets of the oxidative stress generated by ethanol intoxication and withdrawal.
Antioxidant effects have been described due to that alcoholic beverages contain different compounds, such as polyphenols as well as resveratrol. This review analyzes diverse topics on the alcohol consumption effects in several human organs and demonstrates the direct participation of mitochondria as potential target of compounds that can be used to prevent therapies for alcohol abusers. Due to its soluble nature, alcohol does not bind to any tissue nor is it bound to plasma proteins, but can cross the blood brain barrier and placenta 139. Neuropathologic abnormalities in FAS include neuronal-glial heterotopias, cerebellar dysplasia, and agenesis of the corpus callosum, hydrocephalus, and microcephaly 140. These lesions are indicative of aberrant migration, decreased proliferation, and the death of neuronal cells.
- In AD, epidemiological studies have indicated that alcohol consumption plays a role in the development of the disease, due to enhances beta-amyloid (Abeta)-induced neuronal cell death by increasing ROS and mitochondrial dysfunction 138.
- Prenatal exposure to ethanol during fetal development induces a wide spectrum of adverse effects in offspring, such as neurologic abnormalities and pre- and post-natal growth retardation.
- Lowered inhibitions can lead to poor choices with lasting repercussions — like the end of a relationship, an accident or legal woes.
Find freedom from chronic stress using your breath.
Around one out every three liver transplants in the U.S. is the result of liver disease caused by alcohol consumption. Recent investigations have suggested that ethanol influences on special transmitter systems and mechanisms of formation of morphine-analogous condensation products are presented in addiction 130. Also, biogenic amines may react with acetaldehyde to form isoquinoline or carboline compounds, which may enter neural stores and displace the natural neurotransmitter, thus they can act as false neurotransmitters 132.
We tend to underscore the importance of the human liver, however, many alcoholics can tell you with certainty just how important liver function really is. Our livers are essential when it comes to proper food digestion, nutrient absorption, controlling infections, and ridding the body of toxins. There are over two million people in the U.S. who suffer from liver disease caused by excessive alcohol consumption. Liver cirrhosis ranked as the 12th leading cause of death among Americans in 2009. Out of the 31,522 deaths reported that year, 48.2 percent were considered alcohol related.

Even though alcohol doesn’t kill brain cells, it can negatively impact them long-term. For starters, too much alcohol can interfere with neurogenesis, which is your body’s ability to make new brain cells. Drinking can have long-term effects on your brain, including decreased cognitive function and memory issues. Your body breaks alcohol down into a chemical called acetaldehyde, which damages your DNA.

This compound may injure the electron transport chain (ETC) function, leading to production of ROS, which can oxidize the subunits of ETC complexes, leading injury over electron transport and oxidative phosphorylation 72,73, therefore decreasing the ATP levels. In addition, the ROS may lead oxidative stress over lipids causing lipid peroxidation, which affects the permeability of the outer and/or inner mitochondrial membranes. These allows opening of the mitochondrial permeability transition pore (MPTP) and lead to mitochondrial permeability transition (MPT), favoring the translocation to the mitochondria of the pro-apoptotic factor Bax that forms a complex with a voltage-dependent anion channel (VDAC).
But many don’t realize how alcohol impacts our body — especially our brain, liver, stomach, and kidneys. Understanding these effects helps us make smarter choices about drinking. Alcohol may give us a temporary feel-good, but its long-term damage https://shop.farmdroid.io/the-15-best-nonalcoholic-drinks-of-2025/ can be serious and permanent. Discover how alcohol affects brain cells, liver, the stomach, and the kidneys.
