The Cause of Facial Flushing from Alcohol Intake – In most cases, your face turns red after you drink alcohol because your body is having trouble digesting the alcohol. Your body contains enzymes that break down alcohol into acetaldehyde, which is a toxic chemical compound.
The enzyme in charge of this process is called alcohol dehydrogenase (ADH), This is followed by a second step that involves the breakdown of acetaldehyde into non-toxic compounds. The key enzyme that takes the spotlight during this stage is called aldehyde dehydrogenase (ALDH), An error in the aldehyde dehydrogenase 2 (ALDH2) gene that encodes the ALDH2 enzyme can reduce the efficacy of the second step of the process, causing a buildup of acetaldehyde to occur.
This results in facial flushing and other symptoms such as feeling warm, an increase in skin temperature, nausea, headaches, and an increase in breathing rate or heart rate, Essentially, if you experience facial flushing whenever you drink, you could have a faulty ALDH2 gene, which interferes with how well your body is able to metabolize and break down alcohol.

How do you stop getting flushed when drinking alcohol?
Some people’s faces flush after drinking alcohol. If the body cannot metabolize alcohol effectively, too much of a substance called acetaldehyde can build up. This is toxic and can cause a histamine release, resulting in flushing and other symptoms. People with certain genetic features have a higher chance of flushing. Share on Pinterest A red face after drinking alcohol may be a symptom of high alcohol sensitivity. Facial flushing after drinking alcohol is a symptom of high alcohol sensitivity, which means that the body is less tolerant of alcohol. All alcoholic drinks — including beer, wine, and liquors — contain a substance called ethanol.
- After having a drink, the body begins to break down the ethanol into other substances, or metabolites, to make it easier to flush out of the body.
- One of these metabolites, acetaldehyde, is very toxic to the body.
- When drinking in moderation, the body can usually process these metabolites relatively well.
However, if a person is sensitive to alcohol or has a lot to drink, their body may not be able to manage all of those toxins, and acetaldehyde can begin to build up in the body. The red facial flush happens because the blood vessels in the face dilate in response to these toxins.
- In some people, this can happen after very little alcohol.
- A buildup of acetaldehyde can also cause nausea and a rapid heartbeat.
- These symptoms may make drinking alcohol an unpleasant experience, leading to people drinking less.
- While the red flush itself is not acutely dangerous, people who get it are at higher risk of high blood pressure and other health problems.
A 2013 study of Korean men looked at the differences in blood pressure between men who did and did not experience facial flushing when they drank alcohol. After taking factors such as age, weight, smoking, and exercise into account, the researchers found that men who flushed after drinking alcohol had a significantly higher risk of high blood pressure when they drank four or more drinks per week.
- In contrast, men who did not flush after drinking did not see an increased risk of high blood pressure until they drank eight or more drinks per week.
- Studies have also associated drinking alcohol with certain types of cancer.
- Some researchers believe that this increased cancer risk could be due to the rise in acetaldehyde levels in the body.
High levels of acetaldehyde can attack the DNA in the cells of the body, which can trigger the growth of cancer cells. In a 2017 study, researchers looked at the link between cancer and facial flushing after drinking in people in East Asia. Men with facial flushing had a higher risk of cancer, particularly cancer of the throat, which is also called esophageal cancer,
- The researchers did not find the same association in women.
- Whether or not a person’s face goes red after drinking seems to link to their genetic makeup.
- A liver enzyme called aldehyde dehydrogenase 2 (ALDH2) breaks acetaldehyde down into less toxic substances.
- Some people have a genetic condition that means that they do not make this enzyme.
As a result, acetaldehyde builds up in the body after alcohol consumption, which causes the characteristic red flushing of the face. Although anyone can lack this gene, it is more common for people from East Asia not to have it. There is no way to change the genes or enzyme deficiency.
The only way to prevent this red flush and the associated risk for high blood pressure is to avoid or limit the intake of alcohol. Some people use over the counter antihistamines to reduce the discoloration. However, this is not advisable. Although some people may find the flushed skin embarrassing, it is a signal that the body is accumulating toxic levels of acetaldehyde and that it is time to slow down and rehydrate with water.
It is important to recognize that even people who do not get this type of reaction when drinking are still at risk of the health complications of alcohol use, including high blood pressure, liver disease, cancer, and stomach problems. The red flush that some people get while drinking alcohol may not seem serious, but it can indicate that someone has a higher alcohol sensitivity and may have an increased risk of high blood pressure and certain cancers.
While taking antihistamines can help reduce the redness, these drugs only hide the symptoms and do not address the underlying cause. The Centers for Disease Control and Prevention (CDC) recommend that if people choose to drink, they do so in moderation. They define moderate amounts as one drink per day for women and two drinks per day for men.
If a person has high alcohol sensitivity, meaning a low tolerance to alcohol, they may feel the effects of alcohol more strongly and quickly and may benefit from drinking less alcohol. People who are concerned about this symptom can talk to their doctor for advice.
Why do I flush so bad when I drink?
What causes alcohol flush reaction? – Image The alcohol flush reaction is a type of alcohol intolerance—not an “alcohol allergy”—and is a condition predominantly due to inherited variations in genes of certain enzymes, causing people to metabolize alcohol less efficiently. During alcohol metabolism, the enzyme alcohol dehydrogenase (ADH) converts alcohol to acetaldehyde, a toxic molecule.
- The resulting acetaldehyde is metabolized to nontoxic molecules by another enzyme called aldehyde dehydrogenase (ALDH).
- If acetaldehyde is not metabolized efficiently, it can cause release of histamine and thereby trigger flushing and other unpleasant symptoms.
- Variations in the alcohol dehydrogenase gene, ADH1B, and the aldehyde dehydrogenase gene, ALDH2, are well-known variations that lead to higher acetaldehyde levels due to altered alcohol metabolism and are more common among people of East Asian ancestry.
People of other races and ethnicities, however, can also carry these variations. People who take certain medications that alter alcohol metabolism can also experience the alcohol flush reaction. Such medications include those used to treat diabetes, high cholesterol, and infections.
Why does my face get flushed when I drink alcohol?
Should I be worried? – You may be asking yourself this question if you’ve ever experienced facial flushing. On the surface, facial flushing might feel cosmetically embarrassing at most and may not come with any other dangerous symptoms. For those with an enzyme deficiency, facial flushing can occasionally be experienced with increased onset of nausea or vomiting because of your body’s inability to fully digest the alcohol you’re consuming.
For the most part, these factors are mostly harmless. But because alcohol is a cellular toxin, anyone who drinks excessively increases their risk for oral cancer and esophageal cancer, “Alcohol most frequently passes through these sites,” states Dr. Vij. “Toxicity and DNA damage can build up in cells and, eventually, a cancer can form.” But recent studies report that those who get an alcohol flush because of an enzyme deficiency are also at heightened risk of digestive, liver and respiratory cancers,
These populations are more vulnerable to alcohol’s toxicity, as it’s processed and later eliminated in:
Your gastrointestinal (GI) tract, especially your stomach, where alcohol is absorbed. Your liver, where alcohol is sent after it’s absorbed by your stomach. Your lungs, where alcohol in your blood is released in your breath.
How long does alcohol flushing last?
How Long Does Asian Flush Last? Wrapping Things Up – So, how long does Asian flush last? After reading this deep dive on the topic, you should have a better understanding of the timeline for your symptoms of alcohol consumption. Remember – the answer varies from person to person and can even vary from occurrence to occurrence depending on what you drink, how much you drink, what you’ve eaten, and a whole lot more.
- Ultimately, the question “how long does alcohol flush reaction last?” should be replaced with “how can I stop the symptoms of alcohol flush once and for all?”.
- As you now know, there is one alcohol flush treatment that is proven to help eliminate alcohol flushing syndrome – and that is Sunset’s pills.
So, head over to our site to learn more about how these can help you prevent alcohol flush reaction the next time you have a few beverages!
Why does my face get red so easily?
Other risk factors – Other possible causes of facial blushing include:
drinking alcohol, especially red winehot beverageshigh temperaturesfevercold weatherinflammatory conditions allergies certain cosmetics and skin products contact dermatitis
Treating any underlying conditions causing your flushing is often the best remedy. For example, the NHS says that a doctor may recommend medications or a course of psychotherapy to reduce feelings of anxiety if that’s the cause. However, home health options include avoiding specific triggers, such as:
spicy foodshot beveragestoxinsbright sunlightextreme cold or heat
Removing yourself from high-stress situations may also help prevent flushing. It’s important to get immediate medical care for unusual symptoms of flushing. Also, contact a doctor if you’re having recurring episodes, since flushing can be linked to serious medical conditions.
A 2016 review suggests that doctors should take an inventory of symptoms to determine the underlying cause of flushing. The doctor may ask you about your symptoms’ frequency, duration, location, and the context during which they appear. A medical exam and history will help supply the required information for a healthcare professional to make a diagnosis.
Be sure to mention other co-occurring symptoms, such as diarrhea, shallow breathing, or hives, so the doctor may evaluate them. If the doctor finds your symptoms are emotionally based, they may refer you to a psychotherapist. These professionals can teach you skills to help you cope with extreme emotional events and prevent flushing.
Flushing does not commonly result in serious medical problems but may cause feelings of embarrassment or social anxiety. However, in some instances, a serious condition can be the underlying cause of flushing. Without treatment, the underlying condition can lead to complications. There is no definitive method for preventing flushing.
However, you can do some things to reduce the risk of these episodes:
Limit the amount of alcohol you drink: Some people are more prone to redness and warmth on the skin after drinking alcohol. In these people, an enzyme that helps break down alcohol is inactive, resulting in alcohol intolerance. Limit your handling and eating of spicy foods: You may benefit from avoiding foods derived from the Capsicum genus. Try to avoid extreme temperatures: Extreme temperatures and excessive bright sunlight may all result in skin flushing. Limit your niacin intake: The daily allowance recommended by the NIH is 14 to 16 milligrams for adults, unless a healthcare professional tells you differently. Employ coping skills: Regulating extreme emotions such as anxiety may help you to reduce the frequency of your blushing.
Skin flushing or blushing occurs when blood vessels near the skin surface enlarge to accommodate an increased blood flow. When this happens, you may experience redness or other skin discoloration, as well as feelings of warmth in the affected areas. Skin flushing can result from an underlying condition such as rosacea and hyperthyroidism.
Which alcohol causes least flushing?
3. Choose drinks with less alcohol content – Read the bottle labels. Choose red or white wines with 12.5% or less alcohol per volume (APV). Beers, wine coolers, table wine and sparkling wine have lower APV than spirits.
How do I stop my face from turning red?
Make sure you’re hydrated – Drinking lots of water can help keep blushing at bay. Cool or cold water tends to help best. You can even try to prevent blushing by drinking something cool or cold before a stressful event. When reaching for a drink, you may want to skip the alcohol, which can cause facial redness in some people, particularly those of Japanese, Chinese, and Korean descent or those with rosacea.
Do I have redness or rosacea?
Flushing – Most people with rosacea have a history of frequent flushing or blushing. Whether it’s full facial redness or redness primarily in a few areas on the face (cheeks, nose, forehead), this is often the earliest sign of rosacea. That being said, flushing every once in a while doesn’t mean you have rosacea.
What is the fastest way to get rid of acetaldehyde?
Quercetin – Quercetin is a flavonol found in many grains, leaves, vegetables and fruits. Studies have shown that quercetin supplementation has can increase intracellular concentration of glutathione by approximately 50%. As mentioned above, increasing the body’s glutathione levels can help break down acetaldehyde.
Can people with ALDH2 deficiency drink?
Say No to Glow: Reducing the Carcinogenic Effects of ALDH2 Deficiency – PLOS Collections In this piece, Catherine Chang, Tim Ho, Iris Huang, Justin Wu report on the TAS_Taipei iGEM Team’s project from iGEM 2018. Turning red after consuming alcohol may seem like a mere social inconvenience.
- Yet, behind this red complexion lies a far more serious problem.
- ALDH2 deficiency, more commonly known as Alcohol Flushing Syndrome or Asian Glow, is a genetic condition that interferes with the metabolism of alcohol.
- As a result, people with ALDH2 deficiency have increased risks of developing esophageal and head & neck cancers,
Globally, this deficiency affects 540 million people — 8% of the world population. In East Asia (which includes Japan, China, and Korea), this is a much bigger problem, where 36% of the population is affected, In our home, Taiwan, approximately 47% of the population carries this genetic mutation — the highest percentage in the world ! Normally, ethanol is first converted to acetaldehyde (a toxic intermediate) by the enzyme alcohol dehydrogenase (ADH).
- A second enzyme, aldehyde dehydrogenase 2 (ALDH2), then converts toxic acetaldehyde into acetate, a compound which can be safely metabolized in the body.
- For people who carry wild type ALDH2*1, acetaldehyde can be broken down quickly.
- People with ALDH2 deficiency, however, have a point mutation which leads to the less efficient mutant ALDH2*2,,
Enzymatic activity in ALDH2-deficient individuals can be as low as 4% compared to wild type,,,, As a result, acetaldehyde accumulates and induces an inflammatory response that causes the skin to flush after drinking alcohol, Turning red is the most obvious result of ALDH2 deficiency, but symptoms also include headaches, dizziness, hypotension, and heart palpitations,, Acetaldehyde accumulates in ALDH2-deficient individuals, Ethanol is first converted to a toxic intermediate, acetaldehyde, by ADH, then converted to acetate by wild type ALDH2*1. The mutant form, ALDH2*2, cannot fully convert acetaldehyde into acetate, and toxic acetaldehyde accumulates as a result. For people who are ALDH2-deficient and drink, acetaldehyde can accumulate to toxic levels. The International Agency for Research on Cancer classifies acetaldehyde associated with alcohol consumption as a Group 1 carcinogen, Acetaldehyde levels over 50 μM are considered toxic and cause mutations in DNA, and studies show that the strongest effects are seen in the mouth,, After consuming roughly 2 to 3 servings of alcohol (0.5-0.6 g alcohol/kg body weight), salivary acetaldehyde levels in ALDH2-deficient individuals reached over 100 μM, compared to normal levels of <20 μM without drinking,,,, Because of the increased salivary acetaldehyde, people with ALDH2 deficiency are 2 to 8 times more likely to develop head and neck cancers (including oral cancer, pharyngeal cancer, laryngeal cancer, etc.), and 2 to 12 times more likely to develop esophageal cancer compared to people with normal ALDH2*1,
Our ALDH2*1 probiotic candy significantly reduces acetaldehyde levels in simulated oral conditions, (A) The conversion of acetaldehyde to acetate by ALDH2 uses NAD+ and produces NADH. (B) Experimental setup. The candies were dissolved, the probiotic (Nissle) was lysed to release ALDH2 enzymes, and the supernatant was placed into artificial saliva.
- NADH concentration was measured by taking absorbance readings at 340 nm.
- C) Enzymatic activity of ALDH2*1 and ALDH2*2 from the probiotic candies.
- A negative control of candy without Nissle was also included (gray).
- Under these conditions, the ALDH2*1 candies metabolized significantly more acetaldehyde compared to both the ALDH2*2 candies and the negative control.
Error bars represent standard error. To directly address the increased esophageal and head and neck cancer risks, we developed a probiotic ( E. coli Nissle 1917) candy carrying recombinant human ALDH2*1 to maintain normal acetaldehyde levels in the mouths of ALDH2-deficient individuals.
- We tested the candy’s ability to break down acetaldehyde by measuring NADH, a byproduct of acetaldehyde metabolism.
- In simulated oral conditions, we observed a significant decrease in acetaldehyde levels when we added the contents of our ALDH2*1 candy (compared to the mutant ALDH2*2 or control candy).
Through mathematical modeling, we also determined the exact amount of recombinant ALDH2*1 needed in each piece of candy. Our modeling shows that if a consumer eats our candy while drinking, the released ALDH2*1 will be able to combat the high salivary acetaldehyde levels and match the normally low levels found in wild type individuals. Our final product, an ALDH2*1 probiotic candy! Nearly half of Taiwan’s population is ALDH2 deficient. To combat the increased cancer risks associated with this deficiency, we developed and tested a method to regulate acetaldehyde levels in ALDH2-deficient individuals.

What is flush as a symptom?
Blushing is a normal body response that may occur when you are embarrassed, angry, excited, or experiencing another strong emotion. Flushing of the face may be associated with certain medical conditions, such as: High fever. Menopause. Rosacea (a chronic skin problem)
