Jan,
I had an Obs/gyn who was full of old-school wisdom. When learning about my pouch and the fact that my stoma bleeds regularly, even a few drops, every time that I intubate, he exclaimed that blood belonged inside and not outside the body...and that constant loss of blood no matter how small the quantity, could lead to anemia...he put me on higher doses of iron after that.
We have our special anatomy and special needs (no not that way!) and all have diplomas in medicine when it concerns our own bodies, pouches and anatomy.
As I age, things change. My digestion seems to be different too. (My liver may well be responsible for that) So I need to learn to adapt to things again...
I tried to go off of gluten & sugar for a while and my pouch was thrilled. Obviously, once I fell off of the wagon I never managed to climb back up 100%.
I feel that my body is happier without those things but I tend to gravitate towards them anyway so I make compromises...GF pasta helps and so do rice & potatoes, they make the sacrifice easier.
You may need to try different things to see how your body reacts. My skin is clearer and my quality of sleep so much better without the gluten & sugar. I do not bloat or have digestive problems. One would think that that is enough to keep me on the straight and narrow but habits are habits!
Test new diets, write down your results and then modify your diet to what works.
Let me know about the ulcer/scrape...and how they deal with it of fix it!
