Drinking two bottles of beer the night before a medical checkup can have an effect on the results of the checkup, not only on the liver and kidney functions in the blood, blood lipids and blood sugar, but also on the results of the GI ultrasound, especially on the liver and gallbladder. The liver is the main organ that detoxifies the body from alcohol, and when the liver detoxifies, it has an effect on the liver’s aminotransferases. Alcohol intake also affects blood lipids and blood sugar, which may be abnormal during the physical examination, and also affects the liver and gallbladder during the ultrasound. It is recommended that you do not drink alcohol for three days prior to the physical examination and eat a light diet.
