Not bad at all. A half liter is about a pint, the normal amount taken when donating blood. In most cases the body will recover in a few hours and be able to work pretty normally, though there may be a bit of an energy lag for a couple of days. It is actually good for the body to insure that everything is working.
If it wasn't lost through donation, but through trauma, the trauma will cause more issues then the loss of blood.
well if you lose a liter of blood it is very dangerous! you could die if you lost a lot. like a liter of blood ummm if you were talking about a bunch like a volcano gushing out yeah you would probably die. if you lost blood like to fill a small toy truck then you will not die.
It is always dangerous to lose blood. 4 units is no different. A persons body has to maintain a certain amount of blood in order for the heart and other organs to function properly.
blood is in portent
I say you would have to lose half of your blood to lose consencnes, not sure about eyesight
Because you can die of too much blood loss. I hope I answered your question.
They are only dangerous if you lose a lot of blood from them. (Some people don't notice how much they lose, since it drips down their throat rather than out of their nose - this is when it can be slightly dangerous). If you have a nosebleed, tilt your head forward until it finishes. If you go really (deathly) pale, or vomit blood after a nose bleed, see a doctor.
because pizza eat yum yum in bum
You need to see your doctor, because it's dangerous to lose too much blood.
It seems like a lot, but it's really half a cup.
Yes, you can bleed to death. It can be as fast as a couple minutes if you cut an artery. An average adult body holds 7-8 liters of blood. If you lose 2 liters, then shock sets in. losing 4 liters and you will lose consciousness. lose anymore and you can guarantee death. A cut artery will lose about 1 liter a minute, depending on heart rate.
If you are under the age of 18, you should only try to lose weight if your doctor tells you to do so. Lowering your calories can stunt your growth by half, and many 'diet' programs are dangerous to your health.
Vomiting to lose weight is always dangerous. There is no safe way to do it.
