There are several signs and symptoms which indicate that an individual has drunk too much and may suffer from a blackout. A person may be perfectly capable of walking, holding a conversation, or engaging in sexual activities but still remember nothing the day after. The difference between them is that people who pass out fall asleep and lose consciousness completely, while people who black out remain awake and functioning.4 People tend to confuse one with the other because both are caused by an intake of large amounts of alcohol.
A good rule of thumb is to have no more than one standard drink per hour and to drink water in between alcoholic beverages. Blackouts aren’t just about missing memories—they come with significant risks that can impact health and safety. Blackouts are linked to how alcohol affects the hippocampus, the part of the brain responsible for memory formation.
Without food, alcohol hits your bloodstream faster. Drinking a large amount in a short period causes a rapid rise in blood alcohol levels. You may not even realize you were blackout drunk until someone tells you what happened. This article breaks down what it means to be blackout drunk, what causes it, and why it’s more dangerous than you think. Yet many people still don’t understand how serious it is—or how to stop. This is extremely dangerous, as they may attempt to drive, have unprotected sex, or perform other risky behaviors that can lead to permanent harm or even death.
Courts don’t accept memory loss as an excuse for actions taken while intoxicated. Your body’s warning systems become unreliable, and you may continue drinking to dangerous levels without recognizing the signs of overdose. Higher alcohol content beverages consumed quickly (such as shots versus beer) may elevate your risk due to faster absorption rates and higher peak blood alcohol concentrations. Empty stomach consumption accelerates alcohol absorption and leads to higher, more rapidly increasing blood alcohol levels.
Fragmentary Blackout
According to one 2015 study, vasodilatory medications and diuretics could result in syncope blackouts. Experts believe that when people are experiencing a threatening feeling, thought, or memory, it can overwhelm them so much that it induces a seizure. While these blackouts are similar to syncope and epileptic blackouts, the causes are different. However, just because a person has epilepsy, it does not necessarily mean that they will blackout when they have a seizure. During this test, a person lies down on a board that moves to change their position while healthcare professionals measure their blood pressure and heart rate. It could occur when a person’s blood pressure drops after they experience pain or dehydration or get up too quickly.
“Hypnotic drugs are prone to cause this kind of impairment and memory loss,” states Dr. Streem. It can be hard to determine when you’re going to have a blackout or brownout. A person who is blacked out may also throw up while sleeping, which could lead to an increased risk of choking or suffocating. Additionally, blackouts may occur at far lower thresholds among younger populations.
Medical Emergencies
- There’s still time to triple your impact.
- For example, a person who is normally shy may become more outgoing, or a person who doesn’t normally curse may start using profanity.
- There is increasing evidence that repeated alcoholic blackouts actually serve as a mechanism that facilitates alcoholism 2,16.
- But heavy drinking carries a much higher risk even for those without other health concerns.
- This disorder also involves having to drink more to get the same effect or having withdrawal symptoms when you rapidly decrease or stop drinking.
- They have found that exposure to large amounts of alcohol does not kill brain cells, as was once thought.
Over the last two decades, alcohol consumption has dramatically increased in low- and middle-income countries and areas. The greatest levels of alcohol consumption occur in high-income countries, with a slight and sustained decrease in alcohol consumption over the past decade. During the same period of time, the total alcohol per-capita consumption in the Region increased from 4.8 litres to 7.3 litres, surpassing the global average by almost 10%. Globally, the Western Pacific Region has some of the highest alcohol consumption among adults.
Briefly, the hippocampus is abrain structure involved in memory formation for events and has been found to beparticularly sensitive to alcohol. Although early theories posited that alcohol’s effects oncognition and behavior were due to alcohol’s general disruption of brainfunction and depression of the central nervous system, preclinical and clinicalresearch now indicates that alcohol-induced cognitive and memory deficits arecaused by alcohol’s effects on the hippocampus and related neuralstructures (Figure 2) (White et al., 2000). Nearly 77% of the incomingfreshmen reported drinking alcohol in a pre-meditated, intentional mannerwith the goal of becoming intoxicated. They explored the prevalence and correlates ofthis type of drinking behavior in 307 incoming freshman who reportedconsuming alcohol over the past 30 days.
Long-term effects and recovery
It is caused by a rapid increase in blood alcohol concentration (BAC) levels, resulting in a temporary loss of memory. During an alcohol-related blackout, a person is conscious, but later they realize that they don’t remember what happened while they were intoxicated. Those who experience a fragmentary blackout often aren’t aware that they were missing information until they are informed that an event occurred and have little to no memory of the event happening. Sunnyside Med pennsylvania childrens health insurance program offers access to compounded naltrexone (50mg + B6 5mg), paired with behavioral tools to help you reduce your drinking over time.
- Understanding the difference between an alcoholic blackout and passing out remains crucial for recognizing dangerous drinking patterns.
- In the U.S., nearly 14 million women had an average of three binges a month, six drinks at a time.
- If you notice signs of rapid intoxication, such as slurred speech, poor coordination or blurry vision, you may be overconsuming alcohol.
- Althoughprevious research indicates that women are more vulnerable to alcohol-inducedblackouts due to the effect of sex differences in pharmacokinetics and bodycomposition on alcohol bioavailability (Rose andGrant, 2010), the influence of biological sex on alcohol-inducedblackouts are inconsistent.
- Chronic alcohol consumption specifically harms the frontal lobe, which controls cognitive function and memory formation.
- When the hippocampus is exposed to high levels of alcohol, it disrupts the normal functioning of neurotransmitters, impairing memory formation.
- Refine Recovery is available 24/7 to discuss your treatment options.
They may seem like a completely different person. Blackouts are surprisingly common, especially among younger drinkers. It may also be necessary to seek medical help or reach out for support in treating alcohol addiction. If someone blacks out from alcohol, it is important to get them to a safe place where they can rest and recover.

Denying Our Mental Health: Why We Do It and How To Move Past It
In addition to these immediate dangers and possible trauma, there are also long-term health consequences from blacking out. A person who has blacked out could throw up while sleeping due to loss of reflex control and potentially choke or suffocate on their own vomit. According to the National Institute on Alcohol Abuse and Alcoholism, alcohol delays signals in the brain that control the gag reflex and other autonomic responses.
This can be dangerous, as a person who has blacked out could throw up while sleeping and potentially choke or suffocate on their vomit. Adolescent alcohol use can cause persisting alterations in the neurobiology of the hippocampus, leading to cognitive impairments that can extend into adulthood. Studies on college students found a correlation between a higher alcohol use index and accelerated grey matter volumetric change (GMV-c) decline in the hippocampus and parahippocampus. Our compassionate team of experts provides evidence-based treatments, including therapy, support groups, and holistic approaches to healing the mind, body, and spirit. If you or a loved one is struggling with alcohol addiction, don’t wait to seek help. Seeking addiction recovery is not just about detoxing your body—it’s about creating a healthier, more fulfilling life.
Residential treatment programs
People who black out cannot remember where they were or what happened to them after they began drinking. Those whodrink so muchthey can’t remember anything are often still awake and functioning during their blackout. The most pervasive symptom of blacking out ismemory loss.
Using SEM, Read and colleagues (2013) examined whetheralcohol-related consequences, including alcohol-induced blackouts, predictedcollege students’ alcohol consumption one year later and whether theseassociations differed between men and women. Usingstructural equation modeling (SEM), the authors reported a direct pathbetween enhancement motives and blackouts, suggesting that individuals whodrink to increase positive affect might consume alcohol in a manner thatresults in a rapid increase in BAC and alcohol-induced blackouts, such astaking shots of liquor or drinking rapidly. Because drinking motives are predictors of alcohol use andconsequences, recent research has also examined the association betweendrinking motives and alcohol-induced blackouts (Boekeloo et al., 2011; Merrill and Read, 2010; Merrill et al., 2014). Thisprovides additional support for the importance of drinking style (e.g., paceand type of alcohol), as well as amount of alcohol consumed, in theoccurrence of alcohol-induced blackouts.
Whether you’ve blacked out once or dozens of times, you deserve help and healing. The risks are real, but so is recovery. They learn to live without needing a drink to celebrities fetal alcohol syndrome function. People recover from alcoholism every day. This can lead to alcohol poisoning, which can be fatal.
Whether you are new to professional treatment or are familiar with the process, reaching out is the first step toward lasting recovery. Behavioral long covid alcohol intolerance changes include engaging in uncharacteristic risky activities while intoxicated, such as unprotected sex, driving under the influence, or aggressive behavior. These changes include brain tissue shrinkage and impaired neural connections that affect daily functioning. Understanding why you black out when you drink helps you recognize warning signs and carry out preventative measures before reaching dangerous intoxication levels.
Part of the brain that has an important role in storing and creating new memories is called the hippocampus.7 Blackouts happen when large amounts of alcohol enter the bloodstream and the body is unable to deal with the sudden inflow of ethanol in the brain. This level of alcohol intake is known to cause numerous long-term issues. At higher levels of BAC, people are more susceptible to engaging in risky behavior that can lead to accidents with unwanted and unforeseen consequences. Blackouts are more likely to appear when people quickly consume large quantities of alcohol causing their BAC level to rise rapidly. People who experienced a total blackout have no recollection of events that transpired while they were intoxicated.
The Science Behind Alcohol Blackouts: Causes, Risks, and Prevention Strategies
Problems with the law, sexual choices that may endanger our health, and reckless or extravagant expenditures are just some of the possible short-term effects of being blackout drunk.7 Either they drink too quickly, or they’ve developed alcohol tolerance that is increasing their ethanol consumption.6 The fact that blackouts usually happen to individuals who consumed large amounts of alcohol represents a warning that their alcohol intake is becoming excessive. If you want to learn more about blackouts, the interaction of alcohol and medication, or any topic related to alcoholism, hotlines are an easy way to get fully informed.1
When a person blacks out, they make decisions, hold conversations, and even continue to drink. This is especially true for those who take sleep or anti-anxiety medications while drinking. Reasons include their brains being more sensitive to alcohol and their higher levels of fat, which leads to higher blood alcohol levels.7
