1. The physical examination items that need to be carried out on an empty stomach are generally blood drawing and abdominal ultrasound. The main reason is that after people eat it, different ingredients in the food will have different degrees of influence on the examination results, and then interfere with the physical examination results. When doing abdominal ultrasound examination, if there is food in the gastrointestinal tract, it will also affect the development to a certain extent, and it is more difficult to distinguish between normal and abnormal.

2. Therefore, in order to achieve the ideal test results, don't eat and drink willfully when you are prompted that you need an empty stomach.

3. At the same time, in addition to not eating breakfast and drinking water on the day of physical examination, you should also start to maintain a light diet and regular work and rest three days before physical examination, especially to avoid eating high-fat foods, stop eating after dinner the day before physical examination, and try not to eat dinner too late. The idea of eating more on an empty stomach the day before the next physical examination is also not desirable.
