Drinking alcohol may affect the accuracy of the physical examination. Physical examination usually requires liver and kidney function, blood glucose, blood lipids, blood and urine routine, abdominal ultrasound, electrocardiogram and other tests. If alcohol is consumed before the physical examination, it will be metabolized in the liver, which will increase the alanine aminotransferase and glutamine aminotransferase, which will affect the liver function and make the results of the liver function test inaccurate. Drinking alcohol will cause abnormalities in blood glucose and urine routine, so medical checkups after drinking alcohol will cause inaccuracies in blood glucose, blood lipids, and blood and urine routine data. During the physical examination, it should be carried out in a standardized manner under the guidance of a professional physician, and try not to drink alcohol three days before the physical examination, eat a light diet, avoid spicy, stimulating and greasy food, and adjust the rest time so that the results of the physical examination will be relatively more accurate.
