With each alcohol withdrawal episode, the brain and nervous system becomes more sensitised and the resulting side effects become more pronounced. Alcohol has a suppressing effect on the brain and central nervous system. Research has shown that when alcohol is removed from the body, it activates brain and nerve cells, resulting in excessive excitability (hyperexcitability). If you have a little too much alcohol once in a while, it probably won’t do lasting damage if you’re otherwise healthy.
Short-term effects
“Generally, over time, there have been new studies that show that chronic alcohol use — at very heavy use — can lead to brain damage, both gray and white matter. It can cause brain atrophy and shrink your brain over time,” shares Dr. Anand. Before you reach for your next drink, Dr. Anand explains how alcohol can affect your brain — not only alcoholism in the short term, but also in the long run. Alcohol makes you dehydrated and makes blood vessels in your body and brain expand.
This can lead to memory loss, cognitive decline, anxiety, depression, and even permanent brain damage. Heavy drinking can also lead to a host of health concerns, like brain damage, heart disease, cirrhosis of the liver and even certain kinds of cancer. Alcohol is one of the leading causes of death in the United States, contributing to approximately 178,000 deaths annually. Over time, alcohol use takes a toll on your body and increases your risk of over 200 health conditions. From a glass of wine with dinner to a night out with friends or a celebratory toast, alcohol consumption is deeply ingrained in many social practices and cultural traditions worldwide. In the United States, over 84% of adults report drinking alcohol at least once in their lifetime.
Hematologic diseases
However it happens, drinking means you need a sound to be louder so you can hear it. Drinking heavily for a long time has been linked to hearing loss. Whether you’re a light, moderate, or heavy drinker, alcohol can reduce bone mass. Alcohol can cause abnormalities in the blood cells in several ways, including nutritional deficiency, marrow toxicity, and liver disease. Excessive and long-term alcohol use can cause many health complications, which may become severe and life threatening. Pacing yourself (aiming to drink one drink or less every hour), and drinking water between alcoholic drinks may reduce the severity of a hangover.
Permanent Structural Changes in the Brain
- In turn, this disruption can lead to a reduction in vital blood flow.
- Heavy boozing has been shown to up the risk for certain cancers, including breast, liver, mouth, and throat cancer.
- These usually occur shortly after drinking and can last for several hours.
- The duration of alcohol’s effects varies based on factors such as the amount consumed, frequency of use, and an individual’s metabolism.
The pancreas is essential for breaking down enzymes and starches (like those in alcohol). When the pancreas becomes irritated and inflamed, you can develop pancreatitis. Your liver produces enzymes that break down alcohol, but your liver can only handle so much alcohol at one time (approximately 1 ounce per hour). The endocrine system consists of hormone-producing glands in the body. These hormones influence various functions, including growth, metabolism, and breathing.
Breast Cancer
It also interacts with some antibiotics, like metronidazole, making you feel more ill due to a reaction with alcohol,” Dr. Hildahl says. Long-term alcohol use can change your brain’s wiring in much more significant ways. Ways that your standard hangover cures won’t even begin to touch. 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. Like a clog in a drain, those thickened fluids can jam up your ducts.
Alcohol Dependence
- With those who overconsume alcohol, the risks can be higher, including a more severe impact on the brain and even alcohol poisoning.
- Reducing or quitting alcohol can lower your risk of these long-term effects and help you feel sharper, stronger, and healthier overall.
- Alcohol affects innate immunity and also interferes with almost all the various aspects of the adaptive immune response.
- Excessive alcohol consumption doesn’t just affect the liver, though that’s often where the focus lies.

Alcohol interferes with the brain’s communication pathways and can affect the way the brain looks and works. Alcohol makes it harder for the brain areas controlling balance, memory, speech, and judgment to do their jobs, resulting in a higher likelihood of injuries and other negative outcomes. Long-term heavy drinking causes alterations in the neurons, such as reductions in their size.
NIAAA Reviewers
- But long-term, repeated binges can suppress your immune system to the point where you become more susceptible to serious infectious diseases, Duhaney explains.
- Alcohol can have a serious effect on the developing brain, from fetal development to the end of adolescence.
- Notably, women have a higher risk of developing alcohol-induced liver injuries than men.
Alcohol use can damage the hippocampus, the part of your brain responsible for memory and learning. Some studies have found that even light or moderate Alcohol Use Disorder drinking can lead to some deterioration of the hippocampus. We can all experience temporary and long-term effects of alcohol, depending on our consumption. From the first sip, alcohol impacts the body—even if you don’t realize it. Any amount of alcohol can diminish your judgment and functioning, and even low or moderate alcohol use can have harmful effects on different organs. AUD and alcohol use increase the risk of various health complications.
Effects of alcohol on the brain
Research indicates that you’re most vulnerable to alcohol-induced developmental damage between ages 11-14, when your brain undergoes critical developmental milestones. During this period, you’ll experience peak adolescent vulnerability, with a 13.5% risk of progressing to alcohol abuse within 10 years. Drinking alcohol during pregnancy can lead to symptoms of fetal alcohol spectrum disorders (FASD). FASD can cause a range of neurodevelopmental and physical effects in the child after birth.
