    I gave blood yesterday and I've heard that alcohol affects you much more than normal after giving blood (which makes sense). How true is this?

    I'm not sure, but you don't give THAT much blood, I'd wait like a day, then your body would have replenished the blood you lost. It probably affects you more because you have less blood, and alcohol thins your blood?

    I asked this when i was donating once, cause i was drinking the same day.
    You can drink after you've donated blood, but your tolerance will be quite low, and be careful too (aka wait a few hours, if you start to feel weak take some time out, etc)

    I think it would be more because with less blood and the same amount of alcohol the concentration of alcohol in your blood will be higher. I was just wondering how much of an effect that would have though given that you only give a relatively small amount.

    Alcohol is a vasodilator, so with a low blood volume coupled with a larger amount of space for that blood to fill, there is a danger of low pressure, which means poor brain perfusion = passing out

    If you bled a pint, would you still think that it is a relatively small amount?

    Well no but when you give blood it's all kept under control and they only take it if it's absolutely safe to. So it's fine to lose a pint in these circumstances. But I can see where you're coming from.

    It's one of those 'better safe than sorry' measures. Chances are the alcohol will go to your head a bit faster, but in a tiny percentage of cases it may lead to something more serious. So they warn against it just to be safe.

    The amount of blood they take out is a safe amount, but it is still quite a large proportion (up to 13% of total blood is deemed safe, which is why people under a certain weight can't donate).

    I gave blood on my birthday in September - made for a really cheap night!
