So about 2 months ago, my girlfriend passed out on a school trip to Canada, then again at work a week later. Since then she has passed out about 3 other times. One time I was with her and called an ambulance. At first we thought she was hypoglycemic or something, but then she went to like 3 different doctors, and each had a different story. The first said her thyroid was hyper something, the next doctor said hypo something, and the next said her thyroid wasn't working at all. She was just put on perscription about 3 days ago... and just about 20 minutes ago I found out she passed out again. I am worried because none of the doctors seem to be able to make up their minds, and the next time she passes out may be while she's driving. Anybody else have a problem like this before? Any suggestions?
