It takes 9-12 hours for alcohol to be excreted from the body. Also, depending on the amount of alcohol and the body type of each person, it can take up to 24 hours for the alcohol to be completely excreted. Alcohol enters the stomach at first, is absorbed by the stomach, and then participates in the pulmonary circulation and liver metabolism, etc., so that alcohol can be completely eliminated from the body. Urine will excrete 5% of alcohol, while the lungs will excrete 5% of alcohol, and the rest is basically detoxified by the liver, which is very demanding for the liver. Many patients are hungover, and drinking large amounts of alcohol can make the liver particularly strained, and even people with liver disease have a reduced ability to excrete alcohol, all depending on the individual. It is recommended not to drink alcohol in excess.
