My father refused to eat after surgery, how can I help him?

Austinis right, My dad added this to his milkshakes and it did the trick!

Ensure is a good way to get nutrition or carnation instant breakfast which is less expensive and has the same nutrution our hospital use to serve it to pts.

Try milk shakes. Worked for my dad and he gained all his weight back.!

Was he able to tell you why he was refusing? Was it pain or did he say he wasn't hungary, or do you think it was something else?
