My girl friend has syncope but i dont know how serious it is, her mom wont tell her what the doctor said...?

the only thing i know is that its definitely a type of syncope and that the only thing the doctor did is prescribe her some pills. if she only has to take pills, do you think its dangerous? how bad can it be? she overheard the doctor say "all we can do is give her medicine, im sorry"... im really worried, please tell me what you think.

she is 14 years old

First of all, how old is your girlfriend? It is Unethical and Illegal for a doctor to with hold information from a patient. If she is old enough to understand reason and logic thinking then the Dr. must tell her.

I'm going to tell you like I tell most people, if you will go to the search line of your browser, OR, if it's medically related, go to webmd.com, and put in the word that's got you concerned, you can learn a lot of things, a lot faster than waiting for us to help you.
Having said that though, we don't mind helping, cause, that's why we are here.

Syncope means fainting, usually from lack of oxygen to the brain. A decrease in blood supply can cause this. Is she old enough to call her doctor's office? She is legally entitled to know what her medical findings are, and to know how she can help herself. If her mother won't tell her, she needs to talk to her doctor and ask him to explain what she overheard.
