Hyperventilation and Fainting. Normal.

My daughter has been going thru a condition where she hyperventilates and then faints. It all started in May’22. From once a month, it increased to once a week to multiple times a week. Surprisingly, she didn’t have any episode during Aug’22 when we were in India for a holiday. Also, most of her fainting episodes occurred in school. We have witnessed only 2 incidents During the episode we witnessed, she was happily dancing in our family party. She suddenly sat on a chair when I asked her what happened, there were tears in her eyes, she then started hyperventilating & then she fainted. The fainting lasted for 3-4 mins. We are struggling to understand if it is physical health issue, a mental health issue or a mental issue that triggers physical issues. She has been home for the last 10 days as it is winter holidays here and she didn’t have any episode of hyperventilation or fainting while she was having frequent episodes 10 days before the vacations started. Her vitals are normal.
