my granddaughter is 15 and in the last few months has had episodes of suddenly getting chills, then overly warm, her eyes gloss over, she says her vision is gone. She snaps out of it after a couple minutes but this event has happened 4 times. Just tonite at a concert she went blank and had to be taken from the choir. She has had blood work done and has be told she has vasovagal, but these incidents happen close to her period. Is there any possibility of a hormone problem?
Hello and welcome to Ask a doctor service. I have reviewed your query and here is my answer. Yes, there are many hormonal imbalance and changes around the time of menstruation. She must be assessed by an endocrinologist. Another possibility is complex partial seizure, so if there is no effect with treatment by her gynecology then she must see a neurologist. Let me know if I can assist you further in this query.  With Chat Doctor.
