How long does it take to eliminate alcohol after drinking

Once a person's body gets a little bit of alcohol in it, it starts to play havoc with their nervous system. Because alcohol does not pass through the human digestive system, once a person is drunk, his or her consciousness and behavior are completely out of control, and he or she may even do things that he or she regrets. Moreover, if there is a large amount of alcohol in the body, it is not suitable to drive, because if detected by the traffic police, it will be considered as drunk driving. So after a person drinks, how long does it take for the alcohol in the body to be excreted?

Alcohol affects the body before it produces the so-called "feeling" in the brain. It can take effect quickly in the human body and change a person's emotions and behaviors. This is because alcohol does not need to be digested in the human body, it can directly diffuse into the blood and be distributed throughout the body. The process of alcohol absorption may start in the mouth. When it reaches the stomach, a small amount of alcohol can be directly absorbed by the stomach wall. After reaching the small intestine, it will absorb a large amount of alcohol quickly. After alcohol is absorbed into the blood, it flows to various organs, mainly distributed in the liver and brain.

As the main place for alcohol metabolism, the liver is under a very heavy burden. The metabolic rate of alcohol in the liver is limited. If you drink too much, the alcohol will not be metabolized in time and symptoms of poisoning will appear.

If you drink a lot of alcohol in a short period of time, the initial alcohol will act like a mild sedative, making you excited and reducing depression. This is because alcohol suppresses the activity of certain brain centers, which normally inhibit extremely excited behavior. This stage will not last long. Afterwards, most people will become quiet, depressed, dazed, and eventually lose consciousness. In severe cases, they may even suffocate to death due to heart anesthesia or loss of respiratory function.

A small amount of alcohol can be excreted from the body through the lungs or sweat glands immediately after entering the human body. Most of the alcohol first reacts with alcohol dehydrogenase in the liver to generate acetaldehyde, which is harmful to the human body, but it will soon be converted into acetic acid under the action of acetaldehyde dehydrogenase. Acetic acid is the only substance with nutritional value produced after alcohol enters the human body. It can provide the calories needed by the human body.

Experiments have shown that even if you only drink a small glass of beer, it will take at least 6 hours to be metabolized from the body. Generally speaking, alcohol will be absorbed into the bloodstream about ten minutes after drinking, and reaches its peak in about one to one and a half hours. However, while it takes effect relatively quickly, it is metabolized much more slowly.

Judging from the changes in alcohol concentration in human blood, after a normal person drinks a 200 ml glass of beer, the alcohol concentration can reach 20 mg per 100 ml (the standard for driving after drinking); if he drinks three or two low-alcohol liquor or two bottles of beer, the alcohol concentration can reach 80 mg per 100 ml (the standard for drunk driving). Of course, it will vary depending on individual physical conditions.
