Try to get your dad to drink at least two Prosure nutrition drinks a day. Prosure is like Ensure but it has fish oil as well. Recent info from Johns Hopkins suggests that fish oil may ward off some of the "wasting" that is so common among pancreatic cancer patients. You can ask your pharmacist to order Prosure because most don't stock it. It's a little more expensive that Ensure.
Good luck and God bless you all. My husband had a Whipple July '06.
He died June 27. SOME PEOPLE MAKE IT. Keep that thought.
