Hi,

Does anyone know why there is the 7 stone 12lb/ 50kg minimum weight limit for blood donation? I went through all the questions on the site and it said that I'm eligible to donate... unless I weigh less than 50kg, which I do.

I'm perfectly healthy and don't have the most common of blood types either so it's a shame to turn me away.

The less you weigh, the smaller your body is therefore the less blood your body has. So if you lose a certain percentage of your blood through donation, there's a higher risk you will suffer after effects of donating if you have less to lose in the first place.

However, saying that the minimum weight isn't set in stone it's more of a guideline, so if you are otherwise healthy, eligible to donate and aren't significantly underweight (Ie your weight is in proportion to your height) then there is every reason you shoul be able to donate. Blood donation isn't based on how much you weigh, it's based on how much blood your body can afford to lose, which is determined by how much you start with.

I'm really short but not particularly thin for my height. I'm also only a few kg under, so I guess I'll give them a call and see what they think! Thanks.

I was way over the recommended weight limit and I still suffered adverse effects of donating - the first time I had to be looked after by the nurses afterwards, the second time the nurse looked at me halfway through and immediately stopped the donation as apparently my lips had gone the same colour as my skin. They told me not to come back for at least 2 years, except in that time I lost weight so I don't think it'd be wise to try again.

I was 5' 2" and 9st 10lb when I first tried, which is kind of overwight, and now I'm 9st which still isn't really thin. Some people are just stronger than others... So you may as well try, you may be an exception, but be prepared not to be.

Everyone is at risk of adverse effects of donating, however those at highest risk are those who are of a lower weight due to the fact they are losing a higher proportion of their blood when they donate ... which is why the Blood Donor service tend to err on the side of caution.

I think it's a guideline. I was about 7st 10lbs (dont know what that is in KGs) when i donated and I had bad effects.

I conked out just after they'd finished taking the blood and it took me hours to recover. I think my body just missed that pint of blood.
