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?
