i suggest you take your daughter to her pediatrician as a starting point. her symptoms should not be ignored. if the symptoms seem to come and go with her menstrual cycle the problem could be anemia from blood loss. drinking extra water and eating iron-rich foods (red meat fortified grains) might help the problem. however many things could be causing these dizzy spells and it's important you find out what's going on. if there's an underlying illness or condition the sooner you can treat it the better. wishing you well!
11 yr old daughter gets dizzy and will be for hours. today it was sudden and got very pale. where she stays during the day called me to say they were making brownie and she was stirring them up with a mixer and all of a sudden she had to go lay down because she was really dizzy. she was very pale after lying with her feet up and drinking some water she felt a little better not dizzy but not great either. she does wear glasses as of october of last year and she has started her menstral cycle
