I m a 25 year old female and was exercising pretty strenuously today when I started losing vision and had the feeling I was going to pass out. This normally doesn t happen, but I was pushing myself pretty hard. I also have exercise induced asthma and mytral valve prolapse. Is this related to my asthma or is it something different?
