It’s the annual medical examination season again
In the medical examination room, there are always some strange and embarrassing things happening
Urinating with one hand and foot while holding the urine cup and urine tube
Hold a small spoon and watch the shi in the urinal helpless
It feels like countless eyes are staring at your weight after weighing it up
…
Have you ever encountered these embarrassing toe-pulling situations?
Do you know the little health knowledge hidden in embarrassment?
Small Science Time
Not only children are afraid of injections and blood draws
Many adults are also full of fear in the face of needles and blood
The incidence of dizziness is 3.5%[1]
Dizziness, palpitation, sweating and fatigue
Even brief loss of consciousness or confusion
This is related to psychological, environmental, physical and other factors[2]
Excessive tension before blood collection
The vagus nerve, which manages the respiratory and digestive systems, is excited
Induces vascular syncope[3]
Blood collection rooms are often noisy and have poor airflow
Add physical fatigue, sleep deprivation, and excessive hunger
May also cause fainting of blood and needles
People with a history of fainting blood or needles
Sleep well and get enough sleep 1 day before blood collection
If requested on an empty stomach, bring water and a small snack with you
Tell the nurse before blood collection that you have a history of haemorrhage and needle halo
If necessary, lay half or flat for blood collection
Speak to the nurse or escort during the procedure
Do not get up immediately after the blood is drawn
Sit for a while or lie down for a while before getting up to avoid falling

The process of measuring height and weight is comparable to public execution
Young men and women are full of tricks, such as—
Come on, many people have a question:
Who doesn’t have scales and rulers?
Spend so much money for a physical examination, why do you need to check your height and weight?
For more accurate body data
Doctors will use this to analyze whether you have underlying disease factors
For example, if the measurement is accurate
You are shorter than before, and your bones may be wrong
Can also calculate Body Mass Index (BMI)
Weight (kg) ÷ Height (m) 2
Over 28 is obese, over 24 is overweight[4]
for every 2 increase in BMI
Risk of coronary heart disease and stroke
Increased by 15.4% and 6.1% respectively[5]
So, don’t tiptoe or fake, let’s face it!
Small Science Time
During the physical examination, the longest queue is often the B-ultrasound room
Not because of how complicated the check is
The process of holding back urine is too long
Why do I have to hold back?
Because ultrasound is useful for solid, liquid, and gas-containing tissue
The resulting image is different
Full bladder
Images of uterus, ovaries, fallopian tubes, prostate, etc.
It’s more complete and clear[6]
In general, you need to drink 800~1000 ml of water before doing B ultrasound
That is 6~8 paper cups
If you want to hold back your urine quickly
You can drink coffee, tea, watermelon juice and other diuretic drinks
Sip small sips and walk while drinking
Of course, ask your doctor before drinking these drinks
See if it will affect the blood test
It should be noted that not all ultrasound examinations require urination
Liver, gallbladder, pancreas, spleen, vaginal ultrasound, and rectal ultrasound can be directly checked
Don’t be nervous when undressing
Abdominal ultrasound only needs to lift the shirt
Pants are pulled up to the crotch and the belly is exposed

Have you found it
You pee a different color every time
The Cleveland Clinic has launched a “urine color chart”
marked the question corresponding to the color of the urine
Swipe down to read
Normal urine is pale yellow
Drink too much water, and the color of urine becomes lighter
Drinking less water or liver problems can cause dark urine
Have kidney disease, urinary tract infection, prostate infection
Or eat red food, the urine will be red
Eat green food or bacterial infection
Can cause urine to turn blue or green[7]
Urine routine examination can reveal more problems
“-” on the report means normal, “±” means suspicious
“+” means there is a problem, the more “+” the more serious the problem is
pH, specific gravity, occult blood, protein abnormalities
These words may indicate renal impairment
Leukocyte, nitrite, color, and turbidity abnormalities
These words may indicate a urinary tract infection[8]
Of course, whether there is any problem depends on the final report

During a chest X-ray, the doctor usually asks:
Are you trying to conceive?
And remind: It is best to have a baby six months after the chest X-ray
So, is chest X-ray dangerous?
Big!
Chest X-ray is like taking a photo, it’s over with a click
Chest X-ray is like taking a small video and needs to be observed dynamically in real time
Natural radiation is greater
X-ray radiation from human chest X-ray
11.92 times smaller than chest X-ray
The disease detection rate of chest X-ray is 5 times higher than that of chest X-ray[9]
It is recommended to use chest X-ray instead of chest X-ray
If the unit chose a chest X-ray for you
It is recommended to consider adding some money to replace it with a chest X-ray
A chest X-ray usually costs tens of yuan, and a chest X-ray is only about 100 yuan
(There are slight differences in different regions and hospitals of different grades)
Small Science Time
EKG electrodes should be sucked on the skin of the chest
Electrodes on wrist and ankle
Don’t wear dresses, jumpsuits, overalls, and stockings
Loose and comfortable clothing that is easy to put on and take off is preferred
The day before the EKG, it is best not to smoke
Do not drink alcohol, coffee, strong tea and other beverages that accelerate the heart rate
Keep your emotions steady and don’t do strenuous exercise
Get enough sleep the night before
Small Science Time
Surgical exams are a nightmare for many boys
The palpation of the thyroid, superficial lymph nodes, and breast is OK
To the genital examination and digital rectal examination
The feeling is indescribable
Many boys give up surgery, which is wrong
The doctor looks at the genitals to see how the penis is developing
And whether there are external genital deformities, etc.
By touch
Can detect cryptorchidism, varicocele, scrotal hernia, etc.
Anal diagnosis can detect hemorrhoids, anal fissures, anal fistulas, rectal prolapse, etc.
Also helps in early detection of rectal cancer
Don’t be a little embarrassed
and give up such an important inspection
Small Science Time
Itchy, everyone has it
Our ancestors faced harsh living conditionstime
Must maintain a high level of sensitivity
Evolves a sensitive nervous system
As long as something touches the body
The brain sends out alert signals
Body alarm disarms when no danger is realized
Defend by “giggling” or dodging
Axillary, soles of feet and other areas rich in nerve endings
will be more sensitive
Sensitivity decreases around age 40[10]
Just relax and trust the doctor during the checkup
Easter eggs
All inspection items in the physical examination are meaningful
Don’t give up because you feel useless or embarrassed
We did an interesting little survey
