Don’t do these things before the physical examination, otherwise the examination will be done for nothing.

When it comes to physical examination, the most common sentence you have heard is what?

-On an empty stomach, don’t eat in the morning

-Don’t wear heavy makeup,

-Don’t take strenuous exercise,

-Don’t be big fish and big meat,

-Don’t drink


If you really count this, you have heard too many words.

In fact, these are all routine precautions before physical examination, but why do you want to do so? Today, Dr. Clove asked Dr. Chen Zhicong to give you an answer.

No matter who it is, don’t do these things before the physical examination.

1. Don’t eat for 8 hours before physical examination

Fasting blood collection is the basic requirement for physical examination.

On the one hand, eating will cause changes in blood sugar, blood lipid and other results; On the other hand, the normal values referred to in the examination results are counted according to the fasting blood drawing results of healthy people. Fasting blood drawing can better ensure the comparability between the physical examination results and the normal values.

How long will it take?

Fasting generally refers to no energy intake for at least 8 hours.

For example, if you have a physical examination at 8 o’clock in the morning, then you should eat dinner normally the day before the physical examination, stop eating caloric food after 10 o’clock in the evening, and stop eating breakfast the next day, which is OK.

2. Don’t drink a lot of water before physical examination

Although plain boiled water will not affect the results of blood sugar and blood lipid, drinking too much water will promote gallbladder emptying and affect the observation results.

If you need color Doppler ultrasound to observe your gallbladder, you should avoid drinking a lot of water. It is OK to get up and take a sip, but it is not appropriate to drink 500 ml.

3. Don’t eat too greasy 3 days before physical examination.

Pay attention to light diet 3 days before physical examination.

Too greasy food will cause the body triglyceride to increase, affecting liver function examination; Some blood-containing animal viscera, such as pig liver and duck blood, will cause [false positive] fecal occult blood test.

Don’t eat for 3 days before the physical examination.

4. Don’t drink alcohol one week before physical examination

There are also some more out-of-line things. If you drink continuously one week before the physical examination, it may affect the levels of liver transaminase and blood uric acid. If you have no disease, you can find out the disease…

5. Don’t take strenuous exercise 3 days before physical examination,

Strenuous exercise affects the changes of blood pressure and heart rate, promotes the release of insulin and glucocorticoid, consumes energy and affects blood sugar level.

It is suggested to do as little strenuous exercise as possible 3 days before the physical examination, otherwise the examination results are abnormal, and the doctor will suggest to take blood again for reexamination, and we will have to get another injection.

6. Don’t hide your illness during physical examination.

Some patients are worried about revealing their privacy and intentionally or unintentionally hide their physical problems when doctors ask for advice, such as having suffered from hepatitis B before and having blood in their stool.

This kind of one’s own health is actually not helpful.

Doctors’ inquiries and physical examinations can find bad habits that cannot be detected by the machine, such as smoking, drinking and eating too much, and can also detect health problems that cannot be detected by the machine, such as scoliosis or beriberi.

If it is really for your own good, I sincerely suggest that you do not play hide-and-seek with doctors.

Don’t do these things before women’s physical examination.

1. Don’t wear heavy makeup, beautiful pupil or dress.

Dressed beautifully to go to the physical examination mood will be more beautiful, but if you put on heavy makeup, wear a beautiful pupil, wear a dress, doctors will probably frown…

Heavy makeup will affect doctors’ judgment on facial skin, contact lenses are not conducive to ophthalmic examination, and dresses are not easy to wear and take off.

To be honest, why do you wear a dress to go to the physical examination? Why are you wearing jumpsuits? Check for 30 seconds, wear and take off for 5 minutes! There will be people who will keep urging you behind. Why do you dress like that?

Step 2 Do not flush your vagina

When it comes to gynecological examination, many people will do vaginal flushing before physical examination to avoid the embarrassment of peculiar smell during examination.

This is not recommended very much.

Vaginal flushing will not only increase the possibility of pelvic inflammatory disease and ectopic pregnancy, but also affect the routine indexes of vaginal secretions and the examination results.

In fact, peculiar smell is helpful for doctors to judge the real illness, which is really not embarrassing.

Don’t do these things before the physical examination of the elderly.

1. Don’t spend too long on an empty stomach and don’t do morning exercises.

Although fasting is required before physical examination, due to the small liver glycogen reserves of the middle-aged and elderly people, they need to eat well the previous day’s dinner, and it is not recommended to continue morning exercises in the morning to avoid hypoglycemia during physical examination.

Step 2: Don’t stop taking drugs on your own

For the elderly with hypertension, arrhythmia or other chronic diseases, if they have been taking medicine all the time, they should still take medicine regularly before physical examination, and do not stop taking medicine for physical examination, thus causing risks such as blood pressure rise.

Of course, if you have a fever, a cold or diarrhea, etc., it is not recommended to have a physical examination when such acute diseases occur. At this time, the basic indexes such as body temperature and heart rate will be affected, and the examination results will also change. It is not too late to go again when the body recovers.

In fact, Dr. Chen said so much that he hoped everyone would attach importance to physical examination and do a good job in physical examination.

Physical examination is the basis of health. One point of physical examination can bring 10 points of health benefits and reduce the cost of first aid by 100 points. Dr. Clove thinks that he has earned everything he thinks about it.
