i'm a 15 year old girl and a lot of the time i get hot flushes, black out regularly and have dizzy spells (i black out first, then feel dizzy) i don't know whats wrong with me, or if there is anything, but to me, it doesn't seem normal!! please help!!
honey, you need to go see a doctor. There are loads of quite simple things it could be but without seeing you and having all the info, even if one of us was a doctor, we couldn't tell, so go see yours!
When I was your about your age, I used to suffer with something similar for about a year or so after I started my period, I think it was something to do with my body getting used to the hormones, but go and see a doctor anyway as it could be something more sinister
While you are at the docs get your blood pressure checked. I get all the same stuff as you - aparently it's to do with my low blood pressure. But as the others say, it could be lots of stuff, so get it checked out.
