Anyone pass out when they have blood drawn?

I've had blood drawn numerous times... more than the average person, but I passed out for the first time. She stuck me once in my left arm but blood was coming out super slow which she was commenting on so I looked at it and told her to stick my other arm. That arm went fine but I started feeling really woozy then I fainted for a second before they started waking me up and all that. I was sweating a lot and they told me I was super pale and I had to lay down and felt dizzy for about 10 minutes then all was well.They gave me a nice juicebox at least.

Anyone else ever had this happen? Why exactly do people pass out when getting blood drawn? I'm assuming for me it was because I looked at the needle which I never do.

I've had blood taken on quite a few occasions, myself. Never passed out. And I almost always looked at the needle and watched vials fill up.

I fainted when they were drawing blood for a blood test, once. But I have hypotension, so I just assumed it was from a drop in blood pressure.

I've never passed out but sometimes I get sick because I'm anemic.

I almost fainted once about 30 seconds after the vial was drawn. I think it must have a been a blood pressure drop or from not eating, because I've had plenty of blood taken without problems.

Sounds like you have a very low hemoglobin or RBC count or you're simply not eating healthy.. you should get yourself checked for anemia just in case.

Since your blood was coming out slow you're hypotensive, which is also a sign of anemia.

If you're not eating healthy, then you seriously lack nutrients in your diet, B12 and folate deficency usually cause pernicious anemia.

Your blood test result should tell you more...

My diet is actually fairly healthy, however the last time I had blood drawn I was borderline anemic. So, that is possible.

I should probably get my blood pressure checked as well I guess. Hypotension would explain the blood coming out slow, unless she just sucked and missed my bulging vein somehow. I also had a medication change which has hypotension as a side effect as well. Hmm.

I went to donate once, passed out at the finger prick They still took it though. :P

Nope, but I've only donated blood once so that's not saying much.

It's not necessarily a physiological thing. I'm in above-average health and totally not squeamish, but for whatever reason if I catch a look at the needle going in or a vial being filled I get light-headed to the verge of passing out. It's essentially a mild dissociation.

I am guessing thats the case as well. If that is the case then your doc will most probably prescribe you multi vitamins, since anemia has much more complications such as hair loss, fatigue etc... your test should tell you if you're anemic or not.

Make sure to tell your doc about your medication, you could be hypotensive or maybe just a little dehydrated.

He felt dizzy and looked pale which are physiological signs of not recieveing enough oxygen.

Yours is most probably a little nervousness and anxiety associated with the needle.

Nope. I don't donate blood.Fightingfan

Because you are a selfish bastard! D:<

I've nearly passed out twice. Lack of balance, narrowing vision, and nausea. I have low MCH or MCV (something like that), basically means by red blood cells don't carry a lot of oxygen so when I get a lot of blood drawn, I can feel pretty **** Best thing to do is eat and get a lot of fluids in you before you get your blood drawn ...... closing your eyes may help as well.

Thanks for the iDiagnosis eDoc. Say, if I describe this thing on my back to you do you think you can help me out?

Doesn't bother me, I've freaked nurses out before because I like to watch myself get stuck and drawn. Growing up my aunt was training to be a phlebotomist so my cousin and I got to be the Guinea pigs.

no.....but im suprised my heart rate doesnt make me pass out when i do.

No i dont pass out.

Im only a first year PreMed,

You should get it checked out with a real doctor! :P

When having your blood drawn, you gotta look at the needle. It's the rule
