It sounds like she is going to be fine...

so let her eat as much and often as she likes?

I think she stays hungry because her upper bowel is not digesting
nutrients
(im sure a basic understanding of what her body is doing after bowel
surgery would explain just why she cannot absorb all the nutrients)

if she was getting the nutrients her mind would stop telling the body
to eat

all told, with her.. it's about nutrient absorbtion
