I'm a healthy, fit, 25 year old male. I passed out last week, straight after giving blood. They moved my bed into the upright position, I had time to think "crap, I feel funny". Next thing I know, I'm lying down again with a pair of the nurses looking down at me. I felt awful, and it took about 30 minutes to get me back on my feet. They weren't actually sure what caused it (other than a drop in blood pressure, obviously).

passing out is normal it actually happens often. thats why they make you wait 15 min before they release u.

#18, being 22 doesn't matter everywhere. Where I'm from, you have to be 16-17 with parent consent. I've given blood only three times, and I'm only 21. So being 22 is irrelevant.

Don't feel to bad or embarrassed, I'm a 18 y/o 6'1" 180 running back and line backer on the football team and I passed out after donating blood this year

Hello, OP here! Thank You all for your concern! I'm doing a lot better. I actually ended up passing out three more times before they carted me off to the hospital, where I took a nice nap. I think what did me in was my blood pressure, which to me actually seemed low to give blood. I have normally low blood pressure (96/84 is my average) and it was 100/85, or something like that. They also did not attempt to detain me. As for the amount, they took 2 cups from me, so one of the smaller bags. This is a company that regularly visits my university (not the Red Cross, if it was Red Cross it would be different), and my sorority sister who took care of me had two bags taken from her last year, she's about 5'5" and weighs maybe 170lbs and she nearly passed out. I think the next time I give blood, it will be with RC. They made no attempt to stop me as I went up a flight of stairs, handed my meal card over, and made my way over to the pop machine, which is where I fainted for the first time in my life. Thank You again for your concern, and I'm so glad that I did it.

Can they infuse your blood back to you right away;) (aka auto transfusion) Juz teasing. Stay flat. Use extreme caution when you stand up. Sit for 5 min and then stand slowly for 5min before you move about. and drink a lot of fluids with salt and electrolytes. Rehydrate yourself. Make sure you are not anemic. as silly as this sounds you can really hurt yourself with something like this. If you feel that something's not right seek help. If it persists beyond a few days, see a physician and have your heart, endocrine and autonomic nervous system checked out. Next time remember to not squeeze yourself dry when you come across a blood drive :P Disclaimer - above advise does not replace wholly or in part an in person evaluation by a qualified medical professional.

Good on you for trying to do something very noble. :) I'm a blood donor to and I think its very important to donate, they're always needed. Xx

Look at the bright side! At least it was for a good cause! :D

Happens to the best of us!
