I'm happy to hear she doesn't need the oral contrast. The Irinotecan in Folfiri is hard enough on the intestines without adding contrast. Especially with an ileostomy, it seems like an overkill since the oral contrast is just coming out in the bag anyway.
Is she having trouble gaining back the weight from her surgery? I lost 15 pounds after my LAR surgery. I was lean to start with (which the surgeon liked), but then I had a hard time putting the weight back on (which the surgeon didn't like). I used a protein powder too and tried to eat calorie dense foods -- nuts, seeds, nut butters, granola, avocados, and protein bars. It takes work, especially if you are active, but after a few months I was back at my normal weight.
