When you apply for a health certificate, you usually need to have some physical examinations, such as measuring height, weight, blood pressure, and some biochemical indicators, such as blood sugar, cholesterol, liver function, etc. Therefore, in order to ensure the accuracy of the examination results, it is usually recommended not to eat at least 8 hours before handling the health certificate to keep an empty stomach. If you eat before the examination, the food will be digested and absorbed, which will affect the biochemical indexes in the blood and make the examination results inaccurate. For example, blood sugar will rise after eating, which may cover up the real situation of diabetes. After eating fatty foods, the levels of cholesterol and triacylglycerol in the blood will also increase, which may cover up the real situation of hyperlipidemia.
Health certificates are mainly aimed at catering staff and staff of major pharmacies. You need to bring your ID card to the physical examination center or health management center of the local 3A hospital to apply for a health certificate. When you apply for a health certificate, you need to go through the formalities at the front desk and then have a physical examination.

In addition, stool culture should be carried out to see if there are Vibrio cholerae, typhoid Bacillus and paratyphoid Bacillus, and to determine whether there are intestinal infectious diseases. Other examinations include height, weight, blood pressure, spine and limbs.
It usually takes 1-3 working days to apply for a health certificate.
To sum up, in order to ensure the accuracy of the examination results, it is generally necessary to keep an empty stomach when handling health certificates. However, if you suffer from diseases such as stomach trouble or diabetes, you should make adjustments according to your doctor's advice.
