Hi Kitty,
Actually I haven't heard of Appendix Cancer before, so can't help you specifically there. I have had colorectal cancer and have a permanent ileostomy which was in 2000 due to the cancer.
To keep hydrated, you have to drink 2-2.5 litres of fluid a day, i only half of the tea and coffee that I drink (not much), and usually manage the fluids with a little tiny amount of cordial in water.
Is your ileostomy permanent?
In regards to weight, I do watch what I eat in that I minimise non-soluble fibre. I have my vegetables well cooked, pasta is very good at "thickening up things", mashed potato usually works and bananas are very good (a bit expensive at the moment, though). I don't know if you have been told, but when the large bowel isn't being used or is absent (ileostomy) then the fluids from your food isn't absorbed, especially for at least the first 12 months, so that is why extra fluids are required.
Hope that helps a bit,
craftyone
