Different types of alcohol consumption, alcohol consumption, personal constitution, alcohol absorption and metabolism time in the body is different, specific no fixed time can not be estimated. Alcohol is mainly absorbed through the oral cavity, stomach, intestinal mucosa, most of which is metabolized by the liver, and a very small portion of which is excreted through the kidneys with urine, exhaled through the respiratory tract or evaporated through sweat. Alcohol absorption, metabolism and other aspects of the alcohol affect the time of complete metabolism in the body. White wine is fermented wine, glycoproteins other than alcohol, etc., can inhibit gastric peristalsis and delay absorption, and beer is foaming wine, containing a large amount of carbon dioxide, which can stimulate the intestinal tract and accelerate absorption. Food, such as milk, can reduce alcohol concentration, reduce the contact between alcohol and gastric mucosa, delay the absorption of alcohol, prolong the absorption time. After alcohol is absorbed into the blood, it is mainly metabolized into water and carbon dioxide under the action of liver ethanol dehydrogenase, and people with abnormal liver function or low ethanol dehydrogenase content will have their metabolism speed reduced and metabolism time prolonged. The more alcohol is consumed, the more alcohol is present in the gastrointestinal tract, the longer the absorption time and the longer the metabolism time will be. In summary, the metabolism of alcohol is affected by a variety of factors and cannot be accurately predicted. Drinking alcohol is harmful to health and it is recommended to abstain from alcohol, and if you feel unwell, it is recommended that you seek medical attention in a timely manner.
