I would also like to invite @restless1973 to this discussion as well.

Have you been offered any dietary suggestions that might help with this severe nausea and diarrhea? Are you taking any digestive enzymes?

I have had three surgeries of the upper digestive tract and have had a consultation with a registered dietician which was very helpful. Have you been given a referral to a dietician at your hospital?
