How long it takes for alcohol to be metabolized depends largely on the amount of alcohol consumed and individual differences. Different people have different dehydrogenase systems (MOES) in their bodies that determine how well they can detoxify alcohol, and people with dehydrogenase deficiencies can’t drink at all. Some people can increase their alcohol consumption by drinking small amounts of alcohol over a long period of time to induce an increase in the amount of the enzyme. If a small amount of alcohol is consumed, the liver is more capable of detoxifying the alcohol and may metabolize it on its own within a few hours. However, if the amount of alcohol consumed is huge and the liver’s metabolizing ability is poor, it may take half a day or even a day to metabolize the alcohol. Normal alcohol metabolism takes place mainly in the liver, which eventually breaks down into carbon dioxide and water. Some people may liver acetaldehyde dehydrogenase secretion is relatively small, can appear alcohol metabolism obstacle, relative metabolism is slow, usually drink alcohol easy to blush, such people can not drink a lot of alcohol. It is not recommended to drink alcohol excessively, after drinking to promote alcohol metabolism can drink some fruit juice or water. Patients who drink too much alcohol can use intravenous drugs, such as naloxone, brain static, etc. Severe alcoholism may need blood purification treatment.
