Staying hydrated?

My brother just got braces on and he’s sick he’s having difficulty staying hydrated since he’s in pain and doesn’t feel good. I was going to get him someGatorade and pedialyte. Last month he had surgery on his jaw and it was wired shut, the next day he collapsed from being dehydrated so I don’t want that to happen again. Anything else I can get him?
