I'm now 11 months post-Whipple, which I had 8 months after my first PC diagnosis. I found out I was newly diabetic at the same time I found out about the cancer, and have required insulin ever since.

FWIW, I learned the existence of "steatorrhea" and its difference from diarrhea after the surgery. Steatorrhea is specifically the oily, floating, foul-smelling, orange-colored stool that comes from undigested fats.

I had always eaten a lot of Atkins bars and other "sugar-free" snacks, but with the diabetes "side effect," I started eating even more. Unfortunately, most of them use variations of sugar alcohol as a sweetener, which made my diarrhea/steatorrhea worse, so those are mostly out of my diet now. Real sugar can also generate a lot of gas in the gut when it decomposes, but that's a price I'll sometimes pay willingly when comfort food is needed.

Coffee creamer (heavy whipping cream) was the next to go. I found the Starbucks Zero creamers tolerable. Ice cream and real butter are now only consumed in moderation.

I still eat a ton of meat; the calories and protein seem to help me deal well with chemo. But I'm now up to three 36000-unit Creon capsules (108,000 units) with most meals. Timing is sometimes key. One capsule before the meal, one in the middle, and one at the end seems to be a workable formula for me. It helps to stick with leaner meats, and go easy on any oils when you sautee. Fried stuff (fried chicken, especially Buffalo wings with a butter-based sauce, can be a disaster.)

A colleague who had the Whipple a few years before I did gave me two words of advice: "adult diapers." I laughed, but confess they got some use the first 6 weeks after my surgery. If nothing else, for a little peace when trying to sleep through the night.

Regarding gas: I think the tradeoff is gas with too much enzyme, diarrhea/steatorrhea with too little enzyme. I have to say I'm happy to have gas, when the alternative would be poop!

The Tums anti-gas chewables work OK for me. I've read of other folks having good luck with Gas-X. I rarely need the Immodium AD anymore, but take it proactively before a big event or a chemo session.

Everyone is indeed different, but 8 months post-op, I imagine your digestive tract itself is all healed up, and it's just one or two trigger foods (or classes of foods) causing your problem.
