When applying for a health certificate, certain physical examinations are usually required, such as measuring height, weight, and blood pressure. Additionally, biochemical tests—including blood glucose, cholesterol, and liver function—are often conducted. Therefore, to ensure the accuracy of test results, it is generally recommended to fast for at least 8 hours prior to the examination. Eating before the test can lead to digestion and absorption of food, which may affect biochemical indicators in the blood and result in inaccurate readings. For example, blood glucose levels rise after eating, potentially masking the true condition of diabetes. Similarly, consuming fatty foods can elevate blood cholesterol and triglyceride levels, possibly concealing actual hyperlipidemia.
Therefore, fasting is typically required when obtaining a health certificate to ensure accurate test results. However, individuals with medical conditions such as gastric diseases or diabetes should follow their doctor's advice regarding adjustments to fasting requirements.
