I believe all of us who have had a front end Whipple have the same problem with trying to maintain, much less gain, weight. After nearly three years post Whipple, my wife started having me snack daily on peanut butter and jelly snacks she buys at Costco. It might not work for everyone, but it has helped me maintain my weight for several months. For a while, the ensure and high protein drinks helped, but my body now reacts unfavorably to those. If anyone has had luck with any other particular food, I would appreciate hearing of it as it is a daily challenge for me and probably every front end Whipple survivor. I will say however that I am very glad to be alive today and I would have the surgery again today if necessary. Local oncologists wrote me off three years ago, but fortunately I researched and found Dr. Stauffer at Jax Mayo.
