In short, her body is even older than she should be for her age. This was also a concern with Naruto's rapid healing, because Jiraiya mentioned that it was literally shortening his life span. @actionman: i completely agree with @omega here. Lie ive said before, it's a manga/ a fictional story so the creator can bend science if he wants to.
