2. Some scholars think it is an allergic reaction of facial blood vessels. A few patients with alcohol red feel burning sensation on their faces within 5 ~ 10 minutes after being absorbed by ethanol, and at the same time, symptoms such as flushing, pulsating headache, dyspnea, nausea, vomiting, sweating, thirst, chest pain, hypotension, syncope, blurred vision, blurred consciousness and so on appear on their faces or whole body skin. At this time, people think they are drunk, which is called "acetaldehyde syndrome" in medicine, that is, alcohol oxidation.
3, facial capillaries are abundant, and facial skin is relatively thin and transparent, so the effect of transforming alcohol into acetaldehyde to dilate blood vessels first appears on the face, but it lags behind slightly on the body. In addition, some people's palms turn red synchronously with their faces because their skin is transparent and rich in blood vessels.
Why do people look different after drinking?
There are two kinds of enzymes in the human body that can act on alcohol. One is called alcohol dehydrogenase, which can quickly convert alcohol into acetaldehyde. People who contain a lot of this enzyme in their bodies often have the symptoms of blushing in a short time after drinking. The other is called acetaldehyde dehydrogenase. People who blush after drinking only have the former enzyme but not the latter enzyme, so acetaldehyde accumulates rapidly in the body and cannot be metabolized. Therefore, their faces turn red for a long time, and they can only rely on P450 (a group of oxidase with low specificity) in the liver to slowly metabolize the alcohol they consume.
People who drink without blushing belong to the hidden type. Every time it looks as usual, it is always considered to be very drinkable. In fact, they are the most miserable, because there are no two enzymes in their bodies, so they will not show the symptoms of blushing, and they can only be slowly decomposed by the liver. Therefore, such people are most confused about where their bottom line is, and they are most likely to get drunk and suffer from liver damage. So drinking without blushing does not mean that this person must drink a lot. If everyone tries to persuade this person to drink, the tragedy of alcoholism will be extremely high.
There is another kind of people who drink in barrels. The contents of two enzymes in their bodies are extremely high, and the alcohol in their bodies can be rapidly metabolized into sweat and heat. If you meet such people, don't fight with them, otherwise the outcome will be really miserable.
Is it easy to blush when drinking?
People who blush easily after drinking alcohol lack acetaldehyde dehydrogenase, which will cause acetaldehyde to accumulate in the body in large quantities, which will slowly decompose the liver, leading to increased burden on the liver. But compared with people who don't blush when drinking, the advantage of drinking is that as long as they look drunk and say that they have reached the limit, most people will not persuade them to drink again. The alcohol they have already ingested can be decomposed after sleeping for one night, which is not the biggest harm to the human body. If you don't blush when drinking, but you lack two enzymes in your body, such people tend to consume more alcohol than they can bear, and the burden on the liver will be heavier than expected. Therefore, although it is a genetic defect that drinking is easy to blush, from another perspective, blushing can also be saved from the endless wave of persuasion. As long as you stop taking the initiative to drink, the harm to your body is actually not great.
How is blushing after drinking? This means you shouldn't drink it.
Are you a person who blushes when drinking? People who advise wine generally say: the redder represents the more you can drink; People who drink usually say: blushing means my heart is good-but these are just good wishes. In fact, blushing means that you shouldn't drink at all. Don't believe the nonsense that "alcohol is practiced". For people who blush, if they can't, they have to drink. This is death!
How is blushing after drinking? This means you have a genetic defect.
The harm caused by drinking mainly comes from acetaldehyde, and it is also the culprit that makes you blush. In order to eliminate this harm, it is particularly important to metabolize acetaldehyde professionally.
After drinking, alcohol is absorbed into the blood in the digestive tract, of which less than 10% will be excreted from the lungs and kidneys in the original form of alcohol, and the remaining 90% will be metabolized in the liver.
Simply put, alcohol is first catalyzed by alcohol dehydrogenase to acetaldehyde; Then, acetaldehyde becomes acetic acid under the action of acetaldehyde dehydrogenase 2; Then, acetic acid participates in many metabolic pathways in the body, and finally gets carbon dioxide and water, which are excreted. Among them, besides the toxicity of ethanol itself, acetaldehyde is the most harmful, which is toxic to many tissues and organs, may cause DNA damage, and is also considered to have a variety of carcinogenic effects. In animal experiments, acetaldehyde is even used as a mutagen in cancer models.
If something goes wrong with acetaldehyde dehydrogenase 2, acetaldehyde will easily accumulate in large quantities, and soon you will blush. And the problem lies in genes, so there is nothing you can do in this life.
People who blush after drinking are prone to esophageal cancer.
Studies have shown that for alcoholics, genetic defects that make you blush also have an important impact on the high incidence of esophageal cancer. Those who have a "good and bad mixed gene" may have a higher risk of esophageal cancer if they drink alcohol than those who do not have this genetic defect.
Therefore, doctors can judge whether patients have acetaldehyde dehydrogenase -2 deficiency by asking whether they are prone to blush when drinking, and should advise them to drink less and increase the examination of esophageal cancer.
The main subjects of this study are Japanese and people from Taiwan Province Province, China. As a supplement, a paper on 20 10 also studies the situation of mainlanders. The conclusion is similar: Alcoholics with acetaldehyde dehydrogenase 2 gene deficiency are more likely to develop esophageal cancer than normal alcoholics.
To sum up, blushing after drinking is not a bad thing, indicating that you have a genetic defect. Many people judge whether they should continue drinking according to whether they are drunk or not. Some people even think that it is wrong to exercise for a period of time and drink enough. In fact, people who are not good at drinking can tolerate alcohol after exercise, but they will drink more alcohol, which will cause more acetaldehyde to accumulate in the body and cause greater harm. Therefore, people who blush after drinking had better not drink or drink less, which can not only prevent esophageal cancer, but also prevent many diseases.
