What is the medical treatment for starvation?

suppose you say.... got accidentally locked in a bathroom or a janitor's closet for 2 weeks somewhere where you could get ample liquid from a sink but had no source of food what so ever (got that I'm not talking about malnutrition this is total starvation) presumably when they found you after 16 days (I'm adding the week end on to the final week) you would be pretty weak and they'd call an ambulance and send you to a hospital....where they would do what for you exactly? do they just start giving you food again or is it more complicated then that?
