I just had my Whipple (sounds like yours but with Pylorus preserving) 2+ weeks ago at Mayo. Their dieticians put me on a low-fiber diet (actually, in order of food prioritization: low-fiber, low-sugar, low-fat, low-salt). The goals were to not damage new plumbing joints, not become Type 3c diabetic, not experience dumping syndrome, not encourage fluid retention, get enough protein to promote healing, and to get new digestive system working and flowing. My biggest challenge has been eating small enough meals, slow enough, so I do not experience discomfort or have diarrhea/ constipation. I eat 7 small meals a day - starting at roughly 3 oz each (I am up to 6 oz as my largest meal). I take stool softeners every day and laxative at first sign of constipation (Senokot-S covers both). I have Mayo food guidelines but I cannot attach to this Connect Site. Hang in there - it is a marathon and not a sprint.
