if i be taller i understand but why can't i donated when i'm in a normal freight for my height?
Answers:
they dont want you to jump into shock from losing a large volume of blood (bigger person = more blood)
When you donate blood, you give a standard amount--one pint. (Plus they take somewhat more for testing purposes.) They don't adjust that based on size, for the most part (sometimes within special cases, like one sibling donating to another when there is a rare blood type and both are children, they formulate exceptions).
Smaller, lighter people have less blood overall, so taking the standard amount from them is more possible to cause side effects (dizziness, nausea, drop in blood pressure, fainting) than in population who are larger--it's a question of its being a larger percentage of the total blood volume.
I think it's base more on your red blood cell count, not your weight. If your red cell count is low, you will PASS OUT! Also, I believe you need to be at least 18? Your still growing conceivably? I don't really know why a age limit was set unless your very infantile age. Maybe your under weight?
Smaller, lighter people have less blood overall, so taking the standard amount from them is more expected to cause side effects (dizziness, nausea, drop in blood pressure, fainting) than in empire who are larger--it's a question of its being a larger percentage of the total blood volume.In the US it's 110 pounds.
it'll weaken you and the ppl taking your blood could be held for hurting you(if you were to get sick, die, etc.)
You must weigh at least 110 pounds to be eligible for blood donation for your own safety. Blood volume is in proportion to body weightiness. Donors who weigh less than 110 pounds may not tolerate the removal of the required volume of blood as well as those who weigh more than 110 pounds.
well if you be under weight then your body wishes to keep your blood to try and keep you healthy
and if your over freight you increase your risk of heart disiese and stuff so your body still needs blood to prevent this
so basically to give blood you stipulation to be of average height and a certain weight xxx
hope i help x
If you are too thin you will surpass out when drawing blood,and if you are fat you may have bloodclots and cholesterol = obesity relateecstaticases.ask the company to tell you what to to to get in their required cargo?
Because blood volume is directly related to the size of your body. You may be within a normal consignment range for height, but a pint of blood is still a pint of blood.
If you take a 2 cups of blood from someone who have 6 litres (as a normal adult male does, on average) it doesn't affect them adversely.
However if you lug 2 cups of blood from someone who may only have 3.5-4.0 litres of blood like some smaller populace, it can be enough to cause some distress or a dangerous drop within blood pressure.
Basically, the bigger and heavier you are, the more blood volume you have.
Yes, it corresponds to the age limits.
I believe if you are 16, you have to be at least 110lbs and if you're 17, you hold to be at least 100lbs. I'm not sure about for adults, sorry.
ur too skinny n too short. u inevitability all ur blood. cuz if u loose too much, ull pass out n potentially die :[
they wont let u if ur under weight because you involve all the nuitrition you can get and if your over then ovisouly they dont want sick blood
its because they dont want nothing bad happen to you such as ratification out quickly and you dt have that much blood either, powerfully i should know cuz i donate plasma(you get money for that) and they have a weight define also.
because they pprob don't want you a pass out or becuz you might own something wrong idk y don't u go back and ask. its not because ur wait cuz i know associates small and big doing it.
Did they say you be too heavy or too light? A lot of health problems can come up surrounded by your bloodstream if you are either, so they don't want you giving blood that could possibly cause more harm that it would abet.

They take a reliable amount of blood from you when you donate - usually a pint.
If you weigh less, you have less blood surrounded by your body. Therefore, if they took a pint of blood from you, they would be taking a higher percentage of blood from you compared to someone who weighs more.
And, they cannot take smaller quantity blood from you because then they would be giving less blood from your donation to a patient who requests it.
You are at a healthy weight, but they can't take any blood from you because if would craft you extremely weak to lose that high of a percentage of your blood.
I applaud you for wanting to donate blood. It is very crucial that people do it. I would suggest that you gain enough weight to donate and consequently try again.
I've been over the shipment limit for about 57 years now.. I'm 58.
