Dietary precautions before a physical examination

Pre-examination dietary precautions mainly include eating a light diet for 2–3 days, avoiding high-protein and high-fat foods, and abstaining from alcohol. If patients experience any discomfort, they should promptly go to the hospital for evaluation to avoid delays in diagnosis and treatment. Specific details are as follows:

1. Light diet for 2–3 days

Patients should maintain a light diet for 2–3 days prior to a medical examination. During this period, it is acceptable to consume blood-rich foods such as pork blood or pork liver. However, on the day of the examination, fasting and abstaining from water are required. Note that drinking water may be necessary before urinalysis to ensure adequate bladder filling.

2. Avoid high-protein and high-fat foods

Patients should avoid consuming high-protein and high-fat foods 2–3 days before the examination, as these can increase metabolic burden on the liver, potentially causing abnormal liver function. This may lead to elevated levels of blood lipids and cholesterol, resulting in inaccurate test results.

3. Abstain from alcohol

Alcohol consumption should be avoided 2–3 days before the examination. Alcohol can accelerate blood flow and heart rate, potentially affecting the accuracy of blood tests and abdominal ultrasound examinations.

In addition, patients should avoid taking medications that affect liver function the day before the examination to prevent inaccurate results. It is recommended to undergo health checkups at正规 medical institutions and to have regular screenings for disease prevention.
