Generally speaking, it is not possible to eat breakfast before the physical examination, because some tests require fasting. For example, blood sampling for biochemical examination, and liver, gallbladder, spleen and stomach ultrasound examination. If you eat breakfast, you can’t check these items, and if you do, the results will be inaccurate. Therefore, if these items are included in the physical examination, it is not possible to eat breakfast. However, if you only check the functional examination items, such as ECG, atherosclerosis, TCD, etc., and radiological examination, such as head CT, etc., it is actually not a good idea to eat breakfast at this time. This time to eat breakfast is actually not affected, so if the physical examination, try not to eat breakfast, if you eat breakfast, many physical examination items can not be done, try to maintain a fasting state to physical examination.
