Is it a disease that makes you blush when you drink alcohol, which is very common among Asians?

China is a big consumer of alcohol, especially during the holidays, and many people are not drunk. Some people can't see anything after drinking, but some people blush after drinking a little wine. There are many different opinions on the manifestation of blushing after drinking, some persuade that red face is a sign of poisoning, some say that red face means that you can drink, etc., which statement is correct?

<> fact, drinking alcohol blush is neither a sign of poisoning nor a sign of being able to drink, but a sign that does not represent that the body cannot drink. The reason for this is also well-founded. Alcohol mainly contains alcohol, that is, ethanol, which is first converted into acetaldehyde and then acetic acid after entering the human body.

However, this conversion process varies from person to person, and there will be some problems, such as the lack of acetaldehyde dehydrogenase, so after such people drink alcohol, acetaldehyde cannot be converted into acetic acid in time, and acetaldehyde accumulation will cause capillaries in the face to dilate, manifested as redness and swelling.

If you want to know why your face is red after drinking alcohol, you need to know the metabolic process after the alcohol substance enters the human body. After alcohol enters the human body, it is first converted into acetaldehyde under the action of alcohol dehydrogenase, and then continues to be converted into acetic acid under the action of acetaldehyde dehydrogenase. Everyone reacts differently after drinking alcohol, mainly because of the different rates at which alcohol substances break down after they enter the body.

The problem of flushing after drinking alcohol is mainly due to the lack of acetaldehyde dehydrogenase in the body, which is real"Carcinogens"On the one hand, it is toxic, and on the other hand, acetaldehyde causes blood vessels to dilate, resulting in blushing. The greater the amount of acetaldehyde deposited, the worse the blushing.

In other words, people who blush a lot after drinking alcohol are actually more likely to do so"Acetaldehyde poisoning"This kind of person often has problems or drinks a lot of alcohol, which can easily increase the risk of alcohol poisoning. It is important to note that people who blush after drinking alcohol are relatively more likely to develop certain cancers because of the large accumulation of acetaldehyde, which can easily cause damage to the body. Therefore, when you have friends who blush after drinking, don't dissuade them from drinking.

Just because drinking alcohol is more harmful to these people doesn't mean they drink better.

The main component of wine is alcohol, which quickly passes through the mouth, esophagus, stomach, intestines, etc., and directly enters the blood circulation system through the cell membrane without digestion, and is transported to various tissues and organs of the body. About 80%-90% of alcohol is metabolized in the liver and eventually oxidized to carbon dioxide and water, which is eliminated from the body.

Introduction: Drinking a little alcohol at dinner is already a thing that people are accustomed to. Especially for many male friends, drinking alcohol is also an effective way to relieve stress.

During the Spring Festival every year, it is inevitable that family members will sit together for a drink, although it is not recommended to get together in the past two years due to the epidemic, but many people drink three meals a day at home. And some people drink alcohol will cause their face to be very red, some people think that blushing is a sign of a good amount of alcohol, some people say that it is a sign that they can't drink, what is the matter with blushing when drinking?

The blood vessels of the human body are innervated by two main nerves. One is the sympathetic nerve, which dilates blood vessels when excited. The other is the parasympathetic nerve, which dilates blood vessels when they are constricted and inhibited during excitation.

Normally, these two nerves coordinate with each other and innervate the constriction and dilatation of blood vessels. Alcohol excites the sympathetic nerves and inhibits the parasympathetic nerves, causing the blood vessels to dilate larger than usual, which can cause blushing. If the face is thin and has many capillaries, you will be able to make your face red as soon as you drink alcohol.

After alcohol enters the human body, it is broken down in the liver, but when there are no enzymes in the body, some substances in alcohol will accumulate and have the ability to dilate capillaries, so it is easy to blush. Generally speaking, it is more common for Asians to blush or get red after drinking, and if they drink for a long time or drink a lot, the probability of problems is higher than that of ordinary people.

After drinking, alcohol enters the bloodstream through the digestive tract. In addition to the small part being excreted through the respiratory tract and urine, most of it is metabolized through the liver. Normally, alcohol (ethanol) is catalyzed in the human body by ethanol dehydrogenase to acetaldehyde, then turned into acetic acid under the action of acetaldehyde dehydrogenase, and finally oxidized into carbon dioxide and excreted with water.

The amount of these two enzymes associated with alcohol metabolism varies from person to person and is related to genetics. If the body lacks acetaldehyde dehydrogenase, its ability to break down acetaldehyde becomes weaker, causing acetaldehyde to accumulate in the body and the capillaries on the face to swell, eventually leading to blushing.

1. Lack of acetaldehyde dehydrogenase, if the human body lacks acetaldehyde dehydrogenase, it will cause the content of acetaldehyde to increase, and acetaldehyde can dilate capillaries, so if people who drink alcohol have an increase in acetaldehyde, it will cause a red face when drinking.

The lack of this enzyme will not only cause facial flushing, but may also cause alcohol to damage the liver.

It may be because this kind of person is more sensitive to drinking, and it is also easy to cause blood flow too fast, so they will blush.

Related to the body's metabolism, alcohol is broken down into acetaldehyde through the liver. There will be a phenomenon of red face and red ears.

--Of course not. Physical problems.

It's not that it's sick, but that the liver function is good
