Short-Term Effects of Alcohol on Your Health

If a woman consumes alcohol during pregnancy, the child may be born with fetal alcohol syndrome (FAS). Since the liver can only process the equivalent of one drink at a time, the body may remain saturated with the alcohol that has not yet left the body. It can also be difficult for the body to process, putting extra pressure on the liver, the digestive system, the cardiovascular system, and other functions. The frontal cortex is the brain’s center for higher-order functions like planning, decision-making, and impulse control.

Evidence suggests that certain alcoholic beverages, such as wine and beer, appear to accelerate the movement of food and waste through the digestive system, which can lead to diarrhea. Drinking moderately if you’re otherwise healthy may be a risk you’re willing to take. But heavy drinking carries a much higher risk even for those without other health concerns. Be sure to ask your healthcare professional about what’s right for your health and safety.

What Are the Short-Term Effects of Alcohol?

That’s one major reason why you should never drive after drinking. The pancreas helps regulate how your body uses insulin and responds to glucose. If your pancreas and liver don’t function properly due to pancreatitis or liver disease, you could experience low blood sugar, or hypoglycemia. But more recent research suggests there’s really no “safe” amount of alcohol since even moderate drinking can negatively impact brain health. Excessive alcohol use is a term used to describe four ways that people drink alcohol that can negatively impact health.

When newer, larger studies account for these and other variables, the protective effect of alcohol tends to disappear. The findings were widely publicized and promoted by the alcohol industry, and they gained traction in the medical community. It’s always best to connect with your doctor before quitting alcohol. A weakened immune system has a harder time protecting you from germs and viruses. Difficulty absorbing vitamins and minerals from food can cause fatigue and anemia, a condition where you have a low red blood cell count. Alcohol use can also lead to more lasting concerns that extend beyond your own mood and health.

What Are the Effects of Alcohol on the Body?

The studies, however, had some major flaws, including that people’s drinking was generally categorized only by their current behavior. Some people who drink eventually develop a tolerance to alcohol. As a result, they eventually need to drink more to notice the same effects they once did. With these conditions, you’ll only notice symptoms during alcohol intoxication or withdrawal. These symptoms typically improve quickly when alcohol use stops. If your body can’t manage and balance your blood sugar levels, you may experience greater complications and side effects related to diabetes.

Heart and Circulatory System

For millions of people, it’s a regular part of the dining experience, social and sports events, celebrations, and milestones. And the alcoholic beverage industry is a major economic force, responsible for more than $250 billion in sales annually in the US. Decades ago, large surveys of adults began showing an association between how much alcohol someone drank and their risk Alcohol effects 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. That cotton-mouthed, bleary-eyed morning-after is no accident.

• Most of the remaining 80 percent is absorbed through the small intestine.
• Alcohol increases the production of stomach acids and can lead to reflux (stomach acids backing up into the esophagus and the throat).
• In addition to its effects on the brain, alcohol also affects the peripheral nervous system, which comprises the nerves outside the brain and spinal cord.
• During this time, a person may do things that they do not remember later.
• The World Health Organization (WHO) links about 8.1 percent of all tuberculosis cases worldwide to alcohol consumption.

• Over time, it causes heart muscles to droop and stretch, like an old rubber band.
• Or it might damage the nerves and tiny hairs in your inner ear that help you hear.
• Alcohol withdrawal can be difficult and, in some cases, life threatening.
• Some legislators have even proposed adding warning labels on alcohol products — similar to those on nicotine products.

Drinking alcohol on a regular basis can also lead to dependence, which means your body and brain have grown used to alcohol’s effects. That’s because drinking during pregnancy doesn’t just affect your health. It can lead to miscarriage, stillbirth, or premature delivery. Excessive drinking may affect your menstrual cycle and potentially increase your risk for infertility. Experts recommend avoiding excessive amounts of alcohol if you have diabetes or hypoglycemia. Drinking too much alcohol over time may cause inflammation of the pancreas, resulting in pancreatitis.

For men, heavy drinking means more than four drinks on any day or more than 14 drinks a week. Assessing the risks and benefits of alcohol consumption remains an active area of research that may lead to major changes in official guidelines or warning labels. For example, a 2018 study found that light drinkers (those consuming one to three drinks per week) had lower rates of cancer or death than those drinking less than one drink per week or none at all. And not so long ago there was general consensus that drinking in moderation also came with health advantages, including a reduced risk of cardiovascular disease and diabetes. A 2024 report from the American Association for Cancer Research concluded that more than 5% of all cancers in the U.S. are attributable to alcohol use.

It’s worth noting that current guidelines advise against drinking alcohol as a way to improve health. While the idea of abstaining completely may feel daunting, there’s a growing cultural shift toward mindful drinking, or not drinking. Younger generations are drinking less and non-alcoholic beverages are becoming more popular. Surgeon General’s Advisory reported that among 100 women who have less than one drink per week, about 17 will develop an alcohol-related cancer.

The short-term effects of alcohol appear quickly, typically within minutes after consuming your first drink. As you drink an alcoholic beverage, alcohol moves into your bloodstream through the stomach and small intestine. 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. While alcohol is sometimes perceived as a way to manage stress or alleviate low mood, it can often disrupt neurotransmitter balance and worsen conditions like anxiety and depression in the long run. Because ethanol is mostly metabolized and consumed by the liver, chronic excessive use can lead to fatty liver. This leads to a chronic inflammation of the liver and eventually alcoholic liver disease.

Young people and nicotine: 5 things to know

Alcohol impairs the brain’s ability to regulate emotions, and mood changes are common. As the night wears on, you may notice your cheerful feelings soon begin to shift to irritability, sadness, aggression, or anxiety. Heavy drinking, including binge drinking, is a high-risk activity.

Alcohol makes you dehydrated and makes blood vessels in your body and brain expand. Your stomach wants to get rid of the toxins and acid that alcohol churns up, which gives you nausea and vomiting. And because your liver was so busy processing your drinks, it didn’t release enough sugar into your blood, bringing on weakness and the shakes. Normally, this organ makes insulin and other chemicals that help your intestines break down food. Along with toxins from alcohol, they can cause inflammation in the organ over time, which can lead to serious damage. After years, that means you won’t be able to make the insulin you need, which can lead to diabetes.
