The alcohol also impairs the cells in your nervous system, making you feel lightheaded and adversely affecting your reaction time and understanding the dangers of alcohol co-ordination. Dependent drinkers with a higher tolerance to alcohol can often drink much more without experiencing any noticeable effects. By contrast, another 2023 study found similar rates of death between nondrinkers and light to moderate drinkers. Like a clog in a drain, those thickened fluids can jam up your ducts.
As Blood Alcohol Concentration Increases—So Do the Risks
Changing the labels as suggested by the Surgeon General will require congressional action that may never happen. In the past, moderate drinking was thought to be linked with a lower risk of dying from heart disease and possibly diabetes. After more analysis of the research, that doesn’t seem to be the case.
- So, your system prioritizes getting rid of alcohol before it can turn its attention to its other work.
- When BAC reaches high levels, amnesia (blackouts), loss of consciousness (passing out), and death can occur.
- 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.
- 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.
- Drinking alcohol during pregnancy can lead to symptoms of fetal alcohol spectrum disorders (FASD).
What is considered a “drink”?
With no gag reflex, a person who drinks to the point of passing out is in danger of choking on his or her vomit and dying from a lack of oxygen (i.e., asphyxiation). Even if the person survives, an alcohol overdose like this can lead to long-lasting brain damage. Alcohol at very high levels can hinder signals in the brain that control automatic responses, such as the gag reflex. With no gag reflex, a person who drinks to the point of passing out is in danger of choking on their vomit and dying from a lack of oxygen (i.e., asphyxiation). Teenagers and young adults who drink may be at particular risk for alcohol overdose.
Heart and Circulatory System
- Each of those consequences can cause turmoil that can negatively affect your long-term emotional health.
- Alcohol has long been considered a “social lubricant” because drinking may encourage social interaction.
- A .gov website belongs to an official government organization in the United States.
- Kindling is a problem that can occur following a number of episodes of withdrawal from alcohol.
In general, a healthy diet and physical activity have much greater health benefits than alcohol and have been more extensively studied. Drinking too much and too quickly can lead to significant impairments in motor coordination, decision-making, impulse control, and other functions, increasing the risk of harm. Continuing to drink despite clear signs of significant impairments can result in an alcohol overdose, which is sometimes referred to as alcohol poisoning.
As BAC Increases—So Do the Risks
Drinking too much alcohol can weaken the immune system, making the body a much easier target for disease. Drinking a lot on a single occasion slows the body’s ability to ward off infections–even up to 24 hours later. 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. 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.
Gut health
Current research points to health risks even at low amounts of alcohol consumption, regardless of beverage type. Keep reading for more information on how alcohol can affect your body. Even among the positive studies, potential health benefits are often quite small. In addition, alcohol may reduce the risk of one condition (such as cardiovascular disease) while increasing the risk of another (such as cancer). So it’s hard to predict who might actually benefit and who may be harmed more than helped by alcohol consumption.
These effects can also impact the safety and well-being of people around you. No matter how severe the problem may seem, evidence-based treatment can help people with AUD recover.

Risks of moderate alcohol use
Your body breaks alcohol down into a chemical called acetaldehyde, which damages your DNA. Damaged DNA can cause a cell to grow out of control, which results in cancerous tumors. Having a glass of wine with dinner or a beer at a party here and there isn’t going to destroy your gut. But even low amounts of daily drinking and prolonged and heavy use of alcohol can lead to significant problems for your digestive system. Your gut microbiome is a hotbed of bacteria that help keep your digestive system happy and healthy. The trillions of microbes in your colon and large and small intestines are critical to proper digestion.
Don’t play doctor—cold showers, hot coffee, and walking do not reverse the effects of alcohol overdose and could actually make things worse. Know the danger signals, and if you suspect that someone has an alcohol overdose, call 911 for help immediately. Do not wait for the person to have all the symptoms, and be aware that a person who has passed out can die. The less alcohol you drink, the lower your risk for these health effects, including several types of cancer. Binge drinking is behavior that raises blood alcohol levels to 0.08%.
A number of experts have recommended revision of the guidelines toward lower amounts, as more studies have linked even moderate alcohol consumption to health risks. Predictably, the alcoholic beverage industry opposes more restrictive guidelines. In many cases, even moderate drinking (defined below) appears to increase risk. Despite this, less than half of the US public is aware of any alcohol-cancer connection.
It means on days when a person does drink, women do not have more than one drink and men do not have more than two drinks. Binge drinking is drinking enough alcohol to raise one’s BAC to 0.08% or above. Women typically reach this level after about four drinks and men after about five drinks in two hours. Binge drinking—and heavy drinking—is a type of alcohol misuse (a spectrum of risky alcohol-related behaviors). The pancreas is an organ that makes substances that support bodily functions including digestion and metabolism. Alcohol misuse over time can lead to pancreatitis, which can impair the production of digestive enzymes and can affect hormones that regulate blood sugar level.
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. As blood alcohol concentration (BAC) increases, so does the effect of alcohol—as well as the risk of harm. Even small increases in BAC can decrease motor coordination, make a person feel sick, and cloud judgment. This can increase an individual’s risk of being injured from falls or car crashes, experiencing acts of violence, and engaging in unprotected or unintended sex. When BAC reaches high levels, amnesia (blackouts), loss of consciousness (passing out), and death can occur. When BAC reaches high levels, blackouts (gaps in memory), loss of consciousness (passing out), and death can occur.
