What are the precautions before the physical examination

Before the physical examination, it is necessary to pay attention to fasting for 8-12 hours, avoid vigorous exercise, consult a doctor after stopping medication, wear loose clothing, and maintain emotional stability.

1. Fasting Requirements

Most blood test items such as blood sugar, blood lipids, liver function, etc. require fasting for 8-12 hours, during which only a small amount of water can be consumed. Insufficient fasting time may lead to pseudo elevation of indicators such as triglycerides and blood glucose. However, some special examinations such as gastroscopy require longer fasting periods, and specific requirements need to be confirmed with the doctor in advance.

2. Exercise restriction

Vigorous exercise should be avoided 24 hours before physical examination, otherwise it may lead to abnormal elevation of indicators such as creatine kinase and transaminase. Daily light activities such as walking are not affected, but marathons, high-intensity fitness, etc. need to be paused. Immediate physical examination after exercise may affect the accuracy of electrocardiogram, blood pressure and other results.

3. Drug Management

Conventional drugs such as antihypertensive drugs and anticoagulants should be suspended according to medical advice, as antibiotics and hormone drugs may interfere with test results. Patients with diabetes need to consult the doctor to adjust insulin dosage to avoid the risk of hypoglycemia. It is recommended to stop using traditional Chinese medicine and health products for more than 3 days.

4. Dressing Preparation

It is recommended to wear loose cotton clothing without metal accessories to avoid jumpsuits or tight fitting clothes that may affect electrocardiogram, ultrasound, and other examinations. Female breast examination requires removing bras and wearing metal jewelry, which may interfere with the imaging effect of X-rays. Pay attention to layered dressing for easy on and off during winter physical examinations.

5. Psychological regulation

Anxiety emotions may lead to false abnormal results such as elevated blood pressure and increased heart rate. Ensure 7 hours of sleep the night before and avoid drinking stimulating drinks such as coffee and strong tea. Special examinations such as Helicobacter pylori breath tests require maintaining a calm state of mind. Three days before the physical examination, a light diet should be maintained to avoid high-fat and high sugar foods affecting blood test results. Women should avoid undergoing gynecological examinations during their menstrual period, and pregnant or suspected pregnant individuals should inform their doctors in advance. Carrying past medical records and recent examination reports is convenient for doctors to compare and analyze. After emptying the bladder in the morning of the day, keep the morning urine sample and complete all items before eating. Long term medication users need to record the name and dosage of the medication for doctors' reference.
