Introduction
In general, a health certificate requires fasting, although it is not necessary if the individual only undergoes a physical examination. Typically, obtaining a health certificate involves a series of tests, such as routine blood test, liver and gallbladder ultrasound, fasting blood glucose, and blood pressure measurement. If food is consumed before these tests, it may be digested and absorbed by the body, potentially affecting the biochemical indicators in the blood.
Generally, a health certificate requires fasting, but if the individual only needs a physical examination, fasting is not necessary. The specific analysis is as follows:
1. Required
In most cases, obtaining a health certificate involves a series of tests, such as routine blood tests, liver and gallbladder ultrasound, fasting blood glucose, and blood pressure measurements. If food is consumed before these tests, it may be digested and absorbed by the body, potentially affecting biochemical indicators in the blood and leading to inaccurate test results. Therefore, it is recommended to obtain the health certificate while fasting.
2. Not required
A physical examination typically includes measurements such as height, weight, and pulse. These basic physiological parameters are generally unaffected by food intake, so they can be performed at any time and do not require fasting.
If fasting is required, it is advisable to eat promptly after the examination to avoid gastrointestinal discomfort caused by prolonged fasting. If any discomfort occurs during the examination, it is recommended to consult a doctor immediately to prevent adverse effects on health.
