What Does Alcohol Do to Your Body? Short & Long-Term Risks

Multiple studies have been conducted across the globe to understand the effect of alcohol on humans; implications from certain such studies are put forth in Table 1. Through the ages, alcoholism has been undisputedly maintaining its position in the list of risk factors for preventable diseases in the world. According to a WHO report, 5.3% of all deaths that occurred worldwide in the year 2016 were because of harmful alcohol use 1. It is the main culprit behind the advancing nature of many chronic diseases.

This Is What Happens to Your Body When You Stop Drinking Alcohol

Alcohol puts the brakes on your body’s defenses, or immune system. Your body can’t make the numbers of white blood cells it needs to fight germs. So for 24 hours after drinking too much, you’re more likely to get sick.

What Are the Long-Term Effects of Alcohol Use?

Chronic alcohol use raises your risk for health problems, including heart disease, liver disease, cancer, and mental health disorders. Over time, excessive drinking can lead to mental health problems, such as depression and anxiety. Alcohol abuse can increase your risk for some cancers as well as severe, and potentially permanent, brain damage. It can lead to Wernicke-Korsakoff syndrome (WKS), which is marked by amnesia, extreme confusion and eyesight issues.

More information about alcohol’s effects on the brain is available on NIAAA’s topic page on Alcohol and The Brain. Drinking too much – on a single occasion or over time – can take a serious toll on your health. The whole body is affected by alcohol use–not just the liver, but also the brain, gut, pancreas, lungs, cardiovascular system, immune system, and more. Over time, your brain’s structure and function change, leading to tolerance, meaning you may require higher amounts of alcohol to achieve the desired effects. These brain changes contribute to the compulsive nature of addiction, making it difficult to abstain from alcohol.

Alcohol’s effects on the body

Regular drinking can also affect overall mental health and well-being, in part because alcohol may worsen symptoms of certain mental health conditions, including anxiety, depression, and bipolar disorder. The initial contact points — mouth, throat, esophagus and stomach — are most vulnerable, which is why these areas show some of the strongest links to alcohol-related cancers. Stafford and his colleagues said the choice to tip back a beer or forgo alcohol — like many lifestyle decisions — should involve weighing the risks and benefits of your behaviors. But they think the public should be made more aware of those risks, which include an increased risk of cancer from drinking moderate amounts of alcohol. Current research points to health risks even at low amounts of alcohol consumption, regardless of beverage type.

Pancreatitis can be a short-term (acute) condition that clears up in a few days. But prolonged alcohol abuse can lead to chronic (long-term) pancreatitis, which can be severe. Steatotic liver disease develops in about 90% of people who drink more than 1.5 to 2 ounces of alcohol per day. The National Institute on Alcohol Abuse and Alcoholism defines moderate drinking as two or fewer drinks in a day for men and one or less in a day for women.

The physical effects of a hangover will appear as soon as your blood alcohol content (BAC) returns to zero.

Lowered inhibitions can lead to poor choices with lasting repercussions — like the end of a relationship, an accident or legal woes.

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.

Decades ago, large surveys of adults began showing an association between how much alcohol someone drank and their risk of death. People who said they drank heavily had an increased risk, but those who drank nothing at all also had an increased risk compared with those who drank one or two servings of alcohol per day. “Excessive alcohol consumption can cause nerve damage and irreversible forms of dementia,” Dr. Sengupta warns. With continued alcohol use, steatotic liver disease can lead to liver fibrosis. Eventually, you can develop permanent and irreversible scarring in your liver, which is called cirrhosis.
