head rushes and black outs

[lizzie1215]

For the past few years I have been getting terrible head rushes when I stand up.  I often get dizzy and black spots appear.  In the past two months, I have collapsed twice from just standing up.  When there was nothing for me to grab onto to steady myself when I became dizzy, I must have either blacked out or fainted.  A moment later I regained consciousness to discover I had hit my chin on a table on the way down and slammed by head on the ground (also bruising my knee and elbow).  I am scared.  Why is this happening?

Additional information: I am only 19 and have no other medical conditions.  I'm 6'0, 140 lbs.  After blacking out, I am able to function normally again in seconds, but am left with painful bruises.  Am concerned that if this continues, I will end up breaking bones/needing stitches.  Please help.

I'm also 19, but have some other unknown problem which you can read about a few posts down. One of my fairly infrequent symptoms is a partial blackout and dizzyness when standing. I thought this to be a drop in blood pressure, which is possible, but today I realized that from my nausea, I may not be eating enough. In other words, a decreased blood sugar.

Hi your symptoms sound alot like my daughters.  she was 16 and very thin she passed out at a concert and they rushed her to the hospital.  they said she was fine.  i went to follow up with her dr and she refered us to get a tilt table test for a disorder called neurocardiogenicsyncope.  its  a fainting disorder.  she tested positive and then was able to get the help she needed.  it has to do with you heart and brain not staying n sync.  its nothing to be alarmed about.  it happens to alot of people.  look up on the inernet just type in the disorder i gave you and it will tell u all about it.  also when the dr saw her she did her blood pressure and waited about 2 min and did it again and it kept going up and down which is another sign of this disorder.  they like u to drink alot of water and stay out of hot places.  don't stand in one place for along time that can cause u to pass out.  anyway just read about it it will tell you alot then if u have the symptoms tell your dr and ask for a tilttable test.  dont worry my daughter is doing great now hasn't had any problems.

You definetly need to see a Dr. for your symptoms. This could be something serious. Don't fool around find out what is causing it.

Hi, I really can relate to you on your symptoms you have been having. When I stand up at times, I get these head rushes all the time. Sometimes they can be really bad and everything starts going black. If i dont hang on to something I fall over cause i completly loose my balance. I shake uncontrollably for a few seconds then im fine. It usually happens when i get up from sitting down. I have passed out before from this. A couple days ago I started feeling nauseas and weak, my hands started to shake and i broke out in a sweat and needed to sit down. That happened in the mall. I am trying to figure out what I have, I seen a doctor today but what Tula wrote above seemed to bring some clairity to the situation. I hope you are feeling better now. Thanks for your question, it would be nice to get to the bottom of this. Heidi40
