Do you need an empty stomach in the morning to go abroad for medical examination?

"Physical examination should be on an empty stomach". Friends who have experienced physical examination have this impression. The nurse repeatedly told them not to eat after 8 pm and draw blood early tomorrow morning. However, not all physical examinations need an empty stomach and need to be treated differently.

Whether you need an empty stomach depends on the items to be examined. Three routines (blood routine, stool routine, urine routine) can be done at any time without fasting, and ECG, CT, chest X-ray and other tests that do not involve digestion and metabolism generally do not need fasting. Just ask what to do before the inspection, and the inspection agency will pay attention to what to do and make preparations as required. This is why some tests require fasting.

The day before the physical examination, we should maintain our usual living habits (patients with chronic diseases continue to take drugs), eat a normal diet, avoid eating too greasy and indigestible food, avoid overeating, and fast after 8 pm and do not eat midnight snacks.

After getting up the next morning, don't eat breakfast, drink a little water, so as not to feel thirsty, avoid drinking a lot of water, don't do strenuous exercise, and calmly go to the hospital for physical examination.

If there are physical symptoms such as hypoglycemia due to long fasting time, eat immediately and give up the examination.

Drugs such as vitamin C will interfere with most items based on the principle of redox reaction, resulting in inaccurate results. You should stop taking medicine for 3 days before receiving a physical examination.

Women should avoid the physiological period in general examination. Women's menstrual period, pregnancy and other physiological conditions will affect the blood test results.
