I m concerned about my 8 year old daughter. Last week she weighed 49 lbs and this week 42 lbs. Both weights on digital scales. She passed out Friday at school, and has passed out 3 times in the year.. When she does she says the room is black but she can hear the people in the room talking and her lips turn white when she passes out.. She has had numerous test done. And not anemic or her heart. So they are saying it s vagosal synscope. I m really worried, what if it happens when no one is around, when she s in the bathroom at school or something.... Some one said she needs a full panel test and table tilt test....
