Whipple and Sleeping difficulties

If he's having abdominal discomfort, diarrhea, or difficulty digesting food, it would also be worth asking his surgeon or oncologist whether his pancreatic enzyme replacement (such as Creon) is optimized, as digestive symptoms can certainly interfere with sleep.

I would encourage him to mention it to his care team. Sometimes a simple adjustment in medications, pain control, meal timing, or sleep habits can make a significant difference.
