ask: When a child faints or passes out -- what could be the cause?

My niece is 12. On about three or four occasions over the last year or two, she has passed out or fainted. Once was on the softball field; once was at school; once or twice was at home. In each time she was later found to

be either dehydrated or very fatigued; the most recent time she was also suffering from strep throat.

My sister, of course, is horribly concerned, and has taken her to a couple of doctors who have checked her daughter out. However, the consensus seems to be that "some kids do this" -- basically, that some children's bodies have this reaction to getting sick, overly fatigued or dehydrated.

Has anyone heard of this or had this experience? Will a child grow out of it? Is there a specialist we should be taking her to? What is actually going on in her body when she loses consciousness this way?

I'm 16 years old and I've been looking for some answers because I would have the same problem. English isn't my mother tongue so I'll do my best explaining. When I was(If I remember well) in forth grade every morning only early(about 7 to 8 when I woke up for school) for some seconds I would start feeling dizzy.. but not exactly dizzy. I would start seeing weird colors, things moving in a weird way.. I just cant explain it. This strange situation lead me 3 times to faint. So I stayed in hospital for some days. Doctors would say everything was fine, they could find nothing wrong. As I remember I did many exams. Also it was nothing inherited. Of course blood exams, and for the heart, and something strange I had to sleep and the doctor was checking me while sleeping and had a paper like these seismographic ones I cant remember well it was some years ago. I went to special doctors too I remember but Everything was fine. For the summer everything stopped and then I realized it would happen only when I wake up early. So then at fifth grade comes the time when my period starts and all these weird things stop. So they said it has something to do with hormones. I'm still looking for some answers.. I know nothing about this subject I've thought lately about many scenarios.. like what if this hormone reaction happens for example when I( if I ) get pregnant? Maybe it has nothing to do with it.. But I wish someone here would know about this or maybe has experienced ir or anyone around them has so I would know exactly what happened because no one I know has ever experienced this.

My 8 year old daughter passed out at school, took them about 20 minutes to get her to come to, they kept her in the hospital overnight, ran all kinds of test, all were normal except the EEG showed a spot on the left side of her brain.. I have to take her to Cardinal Glennen, but they made her appt for Jan . 15th..... Im worried to death about her to the point of not sleeping good to get up and check on her, and they make the appt. that far away... What if the thing on her brain is growing... Makes me wonder just how much they really care. ..... or is it just money for them...... Im so scared... cancer runs in my family, my mom died from uterus cancer, my grandma had breast cancer and now my sister has colon cancer..... Im scared...

Hello Anonymous,
As a mother, I can appreciate your anxiety and concern. What did the doctor say the "spot on the left side of her brain" was or what does it indicate?

Try contacting the physician who ordered and read the results of the EEG. Press him to explain what was seen and what the implications are. With answers, you will have an understanding and this may reduce your level of anxiety.

I will keep you and your daughter in my prayers.

My youngest passed out for the first time when she was four months old. She is now three years old. As she ages, her episodes have decrease from at least once week (when she was young) to maybe once a month, if that. She only passes out if she is overly tired or gets hurt. She takes a big breath when crying and does not release. I do watch over her more carefully, and try to prevent her from passing out in public. Sometimes, she throws-up after she comes to, but she throws up alot anyway when she cries. On a couple of occasions, she has slept for a couple of hours after passing out (yes I watched over her to make sure she was breathing). I have never called an ambulance. I talked to her doctor, and I was told that some kids pass out. She is otherwise healthy.

I am 21 and have had this problem my entire life. So far doctors have been unable to figure it out either. It has happened to me my entire life. I've learned staying hydrated and out of intense heat coupled with anxiety or stressors help to not trigger it. I hope this helps it is scary when it first happens and just as scary as it continues to happen.

As a child I would pass out I am now 14 and the last time I passed out I was 8 so I believe I have grown out of it but for me it was only for a minute or less that I was out and normally there was a cause of being to hyper or getting hurt. But my doctors said some children just pass out as well.
