Does it matter if you have a health certificate for eating?

Mainly depends on the specific inspection items. The physical examination contents involved in handling the health certificate are mostly routine items, such as height, weight, blood pressure, vision, hearing, cardiopulmonary auscultation, etc. These items usually do not have obvious effects because of eating.

The physical examination of health certificate may also include some biochemical tests, such as blood sugar and blood lipid, and the accuracy of these items will be affected by diet. After eating, the nutrients in the food will enter the blood, leading to the increase of blood sugar, blood lipid and other indicators, thus affecting the accuracy of the test results. If the physical examination requires abdominal B-ultrasound and other imaging examinations, eating may also lead to an increase in gastrointestinal gas and interfere with the examination results.

In order to obtain accurate physical examination results, it is suggested to keep an empty stomach before applying for a health certificate. It is usually recommended to keep an empty stomach for at least 8 hours after dinner the night before, and avoid eating and drinking foods and drinks that may affect biochemical indicators, such as sugar and fat.

When applying for a health certificate, you should also listen to the doctor's guidance and advice, truthfully inform the individual's physical condition and medical history, and ensure the accuracy and reliability of the physical examination results.

To sum up:

Eating when you apply for a health certificate has little effect on the results, depending on the specific inspection items. In order to obtain accurate physical examination results, it is suggested to keep an empty stomach before physical examination and follow the doctor's guidance and advice.
