Anonymous users2024-02-05You may have donated blood! To put it simply, the decrease in red blood cells will make all parts of the body organs not get enough oxygen, and the life functions of the cells can not play normally.
Attention blood donors!
Unscientific blood donation is harmful to health, so do what you can! The average person can only donate less than 200ml! I have heard about serious adverse reactions after blood donation from classmates and relatives!
I've also seen that those with a slightly bad physique will immediately turn pale and may faint! If you have a good physique, you may have an invisible reaction! It may also cause hair loss caused by lack of blood gas!
My wife's college classmates and I both lost our hair after donating blood! I am also in good health, and I go to the hospital at most two or three times a year! I used to think that other people's constitution was too poor, but my own constitution was fine!
The first time I donated blood, I was fine, and the second time I donated 300ml three years later, it caused the ghost to shave my head! Therefore, if you think you have a good physique, you will not necessarily be fine! It's better to be conservative and donate less blood and donate more often!
You have to go through the water, and you can't kill the chicken and take the eggs!

Anonymous users2024-02-02There will be some discomfort during and within an hour of donating blood, and the discomfort will vary from person to person.
A volunteer who has donated blood many times must be very caring.
When you are in good health, you must not donate blood on an empty stomach or when you have just eaten and have not digested a little.
Our blood saved a patient, and occasionally there was discomfort, and it was over after a little resistance.
Donating 400 ml of blood is actually similar to 200 discomfort, however, 400 ml is generally enough for an ordinary patient to use once, if two bags of 200 ml of blood are used, because it is two allogeneic blood, it will be worse for the patient's blood reaction.
Some cities (such as Luoyang) have completely transitioned from 200 ml to 400 ml once, and in the past ten years, all 400 ml have been taken, and there have been no problems.
