I have a fren that is underweight... sometimes she feels sick and she always throw up in school... she once faint in school... my main question is: what healthy food do she need to it to make her weight balance?
She don't want to be underweight... :confused: :(

Hi,
Welcome to this site, and thanks for asking a question here.
She really needs to see a Doctor, if she is vomiting. Gaining weight isn't her problem right now. There is something wrong, and she needs to know what it is. I do wish her the best, and she really needs a Doctor looking at her.
