Over last few years I get really light headed when blood is drawn. Yesterday I blacked out and apparently went into convulsions and hit an assistant, I mean wtf. Needles and blood have never bothered me. I let rookies practice iv sticks on me all the time at work. I played football and have been hit in the head for one reason or another and never been phased.

Why the heck am I doing this with only a few vials of blood drawn? Other than being a big pussy, are there other reasons for this? Like I said, I've gotten light headed in past after 4-5 vials of briefly blacked out. Never anything like yesterday though.

You more than likely had a vagal response, and you have no control over it. Sometimes pain, or stress can cause a drop in blood pressure.

I was told to not eat 12 hours before. Maybe I should eat and just tell them I didn't

This has always happened to me, and I don't understand it.

Maybe something with high or low blood pressure? That's the main thing that I can think would change with blood being drawn

I read that as "vaginal response"...probably same difference.

fricking scary. I've never had a problem but some people react badly.

My pregnant wife passed out while the tech was drawing blood a couple of months ago. They called me in there to get her some water and she was passed out twitching and sweating. She was so hot to the touch. It scared the shite out of me.

Yea, I know. Cool story, bro. But damn that was not cool to see.

For a vagal response to happen, it doesn't matter that your BP is normal before. Vagal response causes a sudden drop in blood pressure, which causes blood to pool in your legs. Its very common, and nothing to get too worked up about- but you should always tell your health care provider prior to drawing blood, so that they can prevent you from falling out of the chair.

That's pretty funny, but.....it is very scary to anyone that happens to experience this phenomenon.

One thing you can do is ask for them to lay you down flat before drawing blood. I'm not sure if it's true or not, but I was told that if you lay flat it is very difficult to pass out. Also, look the other way when they are drawing blood.

I warned the poor nurse prior. I told her I get light headed and briefly black out sometimes for a second or so after 4-5 vials drawn. She just finished 2nd vial when I did it this time. I went into convulsions for about 15-20 seconds.

Next time please alert tech that this will happen. They should lay you down and get the ammonia vial ready. It's quite common, especially for men. The bigger they are, the harder they fall.

I definitely will next time. Kinda embarrassing thing to have to tell a nurse. Full grown man and "hey I need to lay down b/c I'll probably pass out" I was sitting in chair when this happened.

My daughter had this, in her teenage years- she would faint after any kind of medical procedure/pain. Sometimes so bad that she would continue to pass out any time she stood up for 2-3 days. We have been to the emergency room for normal saline infusions to bump her blood pressure back up. Since you are already in your 30's its not likely to go away for you.

I have a similar reaction and believe they would rather know in advance than have to pick your a$$ up off the floor!

Do you have claustrophobia?
I think there's a connection between trouble with blood being drawn and this phobia.
