I figured out the recovery phase of it with the help of the net. But I couldn't find anything on diet restrictions, if there even are any. I suppose he'd get nutrition via IV for the first 2-3 days, then slowly back to solid food and once his stomach is "stretched" (for the lack of a better word) he can eat normally again?
But is there any type of food that is bound to make problems? And how long until he could eat normally again? (usually, I know that this is not an exact science ;) The healing goes without complications, so that's not a factor.
And would he have to take any supplements? Like iron?
