Research has demonstrated that long-term heavy drinking weakens the heart muscle, causing cardiomyopathy. Alcohol misuse can also lead to high blood pressure, an irregular heartbeat (arrhythmia), or increased heart rate. Chronic, heavy drinking raises the risk for ischemic heart disease (heart problems caused by narrowed arteries) and myocardial infarction (heart attack).
Critical Signs and Symptoms of an Alcohol Overdose
Because alcohol mixes with body water, a given amount of alcohol is more concentrated in a woman’s body than in a man’s. As a result, women are more susceptible to alcohol-related damage to organs such as the liver. BAC is largely determined by how much and how alcohol’s effects on the body national institute on alcohol abuse and alcoholism niaaa quickly a person drinks alcohol as well as by the body’s rates of alcohol absorption, distribution, and metabolism. Binge drinking is defined as reaching a BAC of 0.08% (0.08 grams of alcohol per deciliter of blood) or higher.
What is binge drinking?
The good news is that no matter how severe the problem may seem, most people with AUD can benefit from treatment with behavioral therapies, medications, or both. Beyond these physical and mental health risks, frequent alcohol misuse also is linked with personal problems, such as losing one’s driver’s license or having relationship troubles. For some people who drink, it takes quite a few drinks to “get a buzz” or feel relaxed, and they may be less likely to show signs of intoxication compared to others. Blackouts are gaps in a person’s memory for events that occurred while they were intoxicated.
What are the consequences?
Looking forward, NIAAA will continue to work toward a greater understanding of alcohol’s effects on health and society—an understanding that will help more people live long and healthy lives. The Core Resource on Alcohol offers FREE CME/CE credit for 14 practical, evidence-based articles for healthcare professionals about alcohol and health, including foundational knowledge, clinical impacts, and strategies for preventing and treating alcohol problems. Hangover symptoms peak when the blood alcohol concentration in the body returns to about zero. BAC can continue to rise even when a person stops drinking or is unconscious.
- Any time people drink to intoxication, there is a chance they could have a hangover the next day.
- «By joining forces we are able to move the science forward that will lead to important improvements in global public health.»
- Heavy drinking thresholds for women are lower because after consumption, alcohol distributes itself evenly in body water, and pound for pound, women have proportionally less water in their bodies than men do.
- 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.
Alcohol in the stomach and intestine continues to enter the bloodstream and circulate throughout the body. What tips the balance from drinking that produces impairment to drinking that puts one’s life in jeopardy varies among individuals. Age, sensitivity to alcohol (tolerance), sex, speed of drinking, medications you are taking, and amount of food eaten can all be factors. Celebrating at parties, cheering a favorite sports team, and enjoying get-togethers after work are common ways to relax or be with friends. For some people, these occasions may also include drinking—even binge or high-intensity drinking.

Binge drinking—and heavy drinking—is a type of alcohol misuse (a spectrum of risky alcohol-related behaviors). Knowing what counts as a heavy drinking day—4 or more drinks for women and 5 or more for men—can be clinically useful in two ways. The developing adolescent brain is particularly vulnerable to alcohol-related harm. Alcohol is a powerful reinforcer in adolescents because the brain’s reward system is fully developed while the executive function system is not, and because there is a powerful social aspect to adolescent drinking. Specifically, prefrontal regions involved in executive functions and their connections to other brain regions are not fully developed in adolescents, which may make it harder for them to regulate the motivation to drink. Because the brain is adaptable and learns quickly during adolescence, and because alcohol is such a strong reinforcer for adolescents, alcohol use is more likely to be repeated, become a habit, and eventually evolve into a problematic drinking pattern that may lead to AUD.
A typical adult reaches this BAC after consuming 4 or more drinks (women) or 5 or more drinks (men), in about 2 hours. You can promote healthy changes in the brains and behaviors of patients with AUD by encouraging them to take a long-term, science-based approach to getting better. For practical, evidence-based tips on supporting your patients with AUD, see the Core articles on treatment, referral, and recovery. Using alcohol during adolescence (from preteens to mid-20s) may affect brain development, making it more likely that they will be diagnosed with AUD later in life. However, most people with AUD—no matter their age or the severity of their alcohol problems—can benefit from treatment with behavioral health therapies, medications, or both. Alcohol interferes with the brain’s communication pathways and can affect the way the brain looks and works.
This could help explain why women are more likely to have negative effects from alcohol. Drinking alcohol is so common that people may not question how even one beer, cocktail, or glass of wine could impact their health. Alcohol is a part of cultural traditions all around the world…and it’s also a drug that chemically alters the body.
- We then describe evidence-based treatments you can recommend to patients to help the brain, and the patient as a whole, to recover.
- Because alcohol mixes with body water, a given amount of alcohol is more concentrated in a woman’s body than in a man’s.
- Screening by a primary care provider or other health practitioner (e.g., pediatrician) provides an opportunity to identify problems early and address them before they escalate.
- Most of the alcohol is broken down in the liver by the enzyme alcohol dehydrogenase (ADH).
- The developing adolescent brain is particularly vulnerable to alcohol-related harm.
Older people are at particularly high risk for harmful alcohol–medication interactions. Aging slows the body’s ability to break down alcohol, so alcohol remains in a person’s system longer. Older people also are more likely to take a medication that interacts with alcohol—in fact, they often need to take more than one of these medications. Some medications—including many popular painkillers and cough, cold, and allergy remedies—contain more than one ingredient that can react with alcohol. Read the label on the medication bottle to find out exactly what ingredients a medicine contains. Ask your pharmacist if you have any questions about how alcohol might interact with a drug you are taking.

Additionally, NIAAA supports a «brain bank» at the University of Sydney, Australia that collects and distributes autopsied human tissue to facilitate neurological studies conducted throughout the world. This resource takes advantage of a unique population of people who abuse alcohol but no other substances. The consequences of underage drinking can affect everyone—regardless of age or drinking status.
