What is the real cause of drinking blush?

The reason why you blush when you drink alcohol is because it is an alcoholic blush reaction, which is a phenomenon that occurs after drinking alcohol. Half of Asians will have this Asian red face after drinking, but it is rarely seen in other races, this is a genetic trick, Asians have mutations in the acetaldehyde dehydrogenase gene, resulting in deficiencies in the body, but European and American people have very few mutations, and there are relatively more acetaldehyde dehydrogenase.

Some people are more sensitive to alcohol, people who drink alcohol and blush generally have a state of alcohol allergy, it is a little bit of alcohol will blush, this kind of person is not suitable for appearing on the wine table, if it is serious, it may be fatal, alcohol allergy, I think it is due to genetics, if you can't drink, don't drink, don't force yourself, because this will have a certain impact on your body.

Drinking alcohol is not actually caused by alcohol, but by acetaldehyde. Acetaldehyde has the function of dilating capillaries, and the dilation of capillaries in the face is the cause of blushing. So people who drink alcohol and blush mean that they can quickly convert ethanol to acetaldehyde, which means that they have a highly efficient alcohol dehydrogenase.

The blushing is mainly related to two factors, one is whether the skin is thick or not, and the other is whether the microvessels in the face are dilated. Thick skin actually means that there is more subcutaneous fat, and if there is more subcutaneous fat, it is not easy to see the changes in the microvessels under the fat, just like through thick ground glass, it is not easy to see things clearly. Therefore, some people usually look blushing, probably because of their thin skin.

I have a friend who is such a person, he goes out drinking with him, and he blushes after a little drink, and at that time I like to see him blush, so I will pour him a glass of wine, and then he gets drunk, and when I see him like this, I think that he is really bad for alcohol allergy, and I think in my heart that I am not an alcohol allergic.

The main causes of drinking and flushing are as follows:

1. Lack of acetaldehyde dehydrogenase in the human body.

There are two enzymes in the human body that can act on alcohol, one is alcohol dehydrogenase, which is able to quickly convert ethanol into acetaldehyde, and people who have a large amount of this enzyme in their bodies are often able to experience symptoms of flushing within a short period of time after drinking. The other is acetaldehyde dehydrogenase, people who drink alcohol and blush are rich in alcohol dehydrogenase and lack of acetaldehyde dehydrogenase, so the body quickly accumulates acetaldehyde and cannot be metabolized, so it will be red for a long time.

2. Allergic reactions lead to flushing when drinking.

A small number of patients with alcoholic flushing feel burning on the face within 5 10 minutes of ethanol absorption, and at the same time the face or whole body ** appears flushing, throbbing headache, dyspnea, nausea, vomiting, sweating, thirst, chest pain, low blood pressure, syncope, blurred vision and confusion and other symptoms, then people think that they are drunk, medically known as "acetaldehyde syndrome", which is caused by the significant increase in blood acetaldehyde levels caused by ethanol oxidative metabolism.

3. The abundance of capillaries leads to blushing when drinking.

The face is rich in capillaries, and the face ** is relatively thin and transparent, so the effect of converting alcohol into acetaldehyde to dilate blood vessels first appears on the face, while the body lags slightly.

Drinking alcohol and blushing are mostly due to the liver's detoxification function reaching its limit, prompting you to stop drinking, so quickly put down the wine glass. Drinking alcohol without blushing indicates that the liver's ability to break down alcohol is okay, but it should also be in moderation. Drinking too much alcohol is not good for the body.

Why do some people not get drunk after a thousand glasses, and some people pour a drop of wine? Because they lack enzymes that break down alcohol: alcohol dehydrogenase, ADH2, ADH3, alcohol dehydrogenase; People who drink alcohol and blush are only alcohol dehydrogenase without acetaldehyde dehydrogenase, and alcohol is broken down to form acetaldehyde, which accumulates rapidly in the human body and cannot be metabolized.

It's very common to drink alcohol on the face, and genetics, I belong to the type of person who blushes and has a fever when I drink a glass of beer (although I haven't drunk it in more than 5 years), and my dad is like this, even if he drinks a little bit on his face. It is very common for Chinese to drink alcohol on the face, because most of us have the problem of abnormal alcohol metabolism, which is a genetic defect, and it is a very healthy and proud genetic defect.

1. Drinking blush is not a protective color, but a "warning color"!

Most people who drink alcohol and blush have a genetic defect in abnormal alcohol metabolism! The Chinese population has the highest rate of alcohol metabolism gene defects in the world, drinking alcohol increases the risk of n kinds of cancer, you must be moderation, it is best not to drink! No matter what kind of alcohol it is, the appropriate amount of alcohol to drink is "0".

2. Alcohol metabolism in the liver needs to go through two steps.

First, alcohol is metabolized into toxic acetaldehyde by alcohol dehydrogenase (hereinafter referred to as ADH), and then metabolized by acetaldehyde dehydrogenase (hereinafter referred to as ALDH) into non-toxic acetic acid. When the body lacks ALDH, it will lead to a slowdown in the removal of "acetaldehyde", resulting in an increase in the concentration of acetaldehyde in the blood, dilating blood vessels, resulting in faster blood flow and red and hot face. [That's why you blush when you drink].

And acetaldehyde is a carcinogen in the true sense of alcohol, which is toxic to many organs in the body! Not only that, acetaldehyde can also cause headaches, heart palpitations, vomiting, hangovers, and increase the risk of cardiovascular disease and dementia.

So if you drink and blush, you must be vigilant and not drink as much as possible!

Because what we drink is mainly ethanol, after liver metabolism, it will become acetaldehyde, acetaldehyde has the effect of dilating capillaries, and the capillaries of the face are relatively rich, so the telangiectasia of the face causes the phenomenon of blushing, but it is not as some people say, the blushing can drink, and because the secretion of hangover enzymes in the individual's body is insufficient, resulting in the silence of physical alcohol for too long, which will increase the burden on the liver, so it is recommended to drink less

The main reason for drinking alcohol is that the lack of acetaldehyde dehydrogenase leads to drinking blush, because people who are prone to blush when drinking alcohol lack acetaldehyde dehydrogenase, a large amount of acetaldehyde cannot be excreted, and it accumulates in the body, and the liver slowly decomposes it, which will lead to an increase in the burden on the liver.

Drinking blush is a sign that your body is telling you that you have consumed too much alcohol, which is causing harm to your body, and it is recommended to stop.

So. When you meet someone who blushes from drinking, don't persuade you to drink!

This condition is the lack of an enzyme in the body, which is individual, innate, and genetic, and there is no particularly good way to do it. There are also few drugs that can improve the effects of this enzyme. It is necessary to avoid drinking alcohol as much as possible to avoid affecting the body.

1. Lack of ethanol.

Dehydrogenase causes blush when drinking.

There are two enzymes in the human body that can act on alcohol, one is called alcohol dehydrogenase, which can quickly convert ethanol into acetaldehyde, and people who have a large amount of this enzyme in their body are often able to show symptoms of flushing within a short time after drinking. The other is called acetaldehyde dehydrogenase, people who drink alcohol and blush are only the former enzyme and no latter enzyme, so the body quickly accumulates acetaldehyde and cannot be metabolized, so it will be red for a long time, and you can only expect the liver to slowly metabolize the ingested alcohol.

2. Lack of acetaldehyde dehydrogenase leads to blushing when drinking.

The lack of acetaldehyde dehydrogenase in the body of people who are prone to blushing after drinking alcohol will lead to the accumulation of a large amount of acetaldehyde in the body, allowing the liver to slowly decompose, which will lead to an increased burden on the liver. But compared with people who don't blush when they drink, the advantage of blushing easily when they drink is that as long as they are drunk and red, saying that they have reached the limit, ordinary people will no longer persuade them to drink, and the alcohol that has been ingested can be decomposed as long as they sleep overnight, and the harm to the human body is not the greatest. If you don't blush when you drink alcohol, but you don't have two enzymes in your body, you tend to consume more alcohol than you can tolerate, and the burden on your liver will be heavier than you think.

In addition to the lack of alcohol dehydrogenase and aldehyde dehydrogenase in the body, what are the other reasons for the flush when drinking alcohol? Let's find out.

3. Allergic reactions lead to blushing when drinking.

Some scholars believe that it is an allergic reaction to the blood vessels of the face. A small number of patients with alcoholic flushing feel burning on the face within 5 10 minutes of ethanol absorption, and at the same time the face or whole body ** appears flushing, throbbing headache, dyspnea, nausea, vomiting, sweating, thirst, chest pain, low blood pressure, syncope, blurred vision and confusion and other symptoms, then people think that they are drunk, medically called "acetaldehyde syndrome", which is caused by the significant increase in blood acetaldehyde levels caused by ethanol oxidative metabolism.

Many people think that drinking alcohol is the cause of blushing, but this is not the case. Alcohol, the main component is ethanol, after ethanol enters the human body, it is converted by ethanol dehydrogenase to form a new substance, acetaldehyde, and acetaldehyde can make the capillaries in the body dilate, as soon as the blood vessels dilate, the face will naturally be rosy. In addition, due to the differences in each person's physique, some people do not have acetaldehyde dehydrogenase in their bodies, and without this enzyme, the acetaldehyde converted from alcohol cannot be catabolized in the body, but can only accumulate all the time, so it will also appear on the face.

At this time, someone is about to ask, what to do without this dehydrogenase, here I want to tell you, don't worry, the liver can slowly convert acetaldehyde into acetic acid, metabolically decomposed, just after a period of time, rest assured.

Drinking alcohol blushes because everyone has different hangover enzymes in their bodies, the first is a genetic problem, some people themselves can't drink too much alcohol, and they blush when they drink alcohol because the hangover enzymes in the body are low, and the second is because the liver is damaged and asking you for help, indicating that you can't drink anymore.

After drinking, the body metabolizes alcohol by two enzymes, which are alcohol dehydrogenase and acetaldehyde dehydrogenase. After drinking alcohol, the body responds to the alcohol dehydrogenase that converts alcohol into acetaldehyde, and then converts and metabolizes acetaldehyde through acetaldehyde dehydrogenase. If there is a lack of acetaldehyde dehydrogenase enzyme in the body, the metabolic process of acetaldehyde is hindered, and too much acetaldehyde can cause capillaries to dilate, which can lead to blushing.

Therefore, people who are prone to blush when they drink alcohol are because their bodies contain highly efficient alcohol dehydrogenase, which can quickly convert alcohol into acetaldehyde, and the body lacks acetaldehyde dehydrogenase, so acetaldehyde continues to accumulate, resulting in capillary dilation.

Some people have a red face after drinking, but after 1-2 hours, the face returns to normal, because acetaldehyde is also converted into acetic acid by a less specific oxidase enzyme in the liver, and then metabolized, so the face returns to normal.

Of course, not everyone blushes after drinking. Some people not only do not have a red face after drinking, but also turn white, what is the reason for this? This is because these people have neither alcohol dehydrogenase nor acetaldehyde dehydrogenase in their bodies.

The alcohol they drink is basically slowly oxidized by specific oxidative enzymes in the liver, so the more they drink, the whiter their faces become.

1. Lack of ethanol dehydrogenase leads to blushing when drinking;

2. Lack of acetaldehyde dehydrogenase leads to blushing when drinking.

3. Allergic reactions lead to blushing when drinking.

4. The abundance of capillaries leads to blushing when drinking.

Because the face is rich in capillaries, and the face ** is relatively thin and transparent, the effect of alcohol converted into acetaldehyde to dilate blood vessels first appears on the face, while the body lags slightly. In addition, some people's palms turn red in sync with their faces, and the reason is that their palms are transparent and rich in blood vessels.

The distinction between blushing and not blushing is as follows: ** post).

Two issues must be clarified:

1 is the problem of race, and 2 is the problem of metabolic enzymes and individual differences.

Some races are adapted to drinking, such as Mongols in the race, Eskimos, etc.

Regarding enzymes, there are two main types of alcohol metabolism in the human body: alcohol dehydrogenase and acetaldehyde dehydrogenase. When alcohol enters the body, it is first metabolized to acetaldehyde by ethanol dehydrogenase, which then metabolizes acetaldehyde into acetic acid and water.

There are several possibilities here:1If both enzymes are extremely active, the drinker will be able to drink without blushing; 2.

If the ethanol dehydrogenase is very little or inactive, this kind of person must not drink alcohol or can not drink a lot of alcohol, ethanol can not be quickly metabolized will cause acute alcohol poisoning, affect brain function, serious consciousness disorders, severe cases can also affect the liver, heart and other organs, and even death.

3.If the alcohol dehydrogenase is active, the acetaldehyde dehydrogenase is inactive, a large amount of acetaldehyde can not be metabolized in time, so that the acetaldehyde accumulates in the body, and poisoning can also occur, blood vessels dilate, red face, red ears, headache, increased heart rate, etc., and in severe cases, it can also lead to death.

4.If the alcohol dehydrogenase is not active, the aldehyde dehydrogenase is active, so that it is the same as in the first case, that is, you cannot drink and do not blush.

In daily life, some people quickly appear red after drinking, and most people think that this is a sign of intolerance, what is going on? In medicine, this phenomenon is called "drinking flushing".

Facial flushing is caused by temporary subcutaneous vasodilation, and the concentration of ethanol in the blood rises rapidly after drinking, which can cause facial blood vessel dilation, facial redness, and even full-body flushing, sometimes accompanied by urticaria and itching, the mechanism is not fully understood, and some scholars believe that it is an allergic reaction to facial blood vessels. A small number of patients with lead alcohol flushing within 5 10 minutes of ethanol absorption, the face feels burning, and at the same time, the face or the whole body ** appears flushing, throbbing headache, dyspnea, nausea, vomiting, sweating, thirst, chest pain, low blood pressure, syncope, blurred vision and confusion and other symptoms, then people think that they are drunk, medically called "acetaldehyde syndrome", which is caused by ethanol oxidative metabolism caused by significant blood acetaldehyde levels.
