Hi,
I'm living without my pancreas, spleen and gall bladder, all removed in one 7 hour procedure in January 2004. All this became necessary due to a rare condition, mucinous duct ectasia (of the pancreas).
My quality of life has improved constantly since the procedure, assisted greatly when I changed to using an insulin pump. The enzymes need to be taken any time I eat, otherwise its apparent at the next bowel movement. I am able to eat almost anything as long as I count the carbs (so I know how much insulin to take). The diabetes is definitely the worst side effect of the surgery, fortunately the research into diabetes and its treatments is well funded. The strongest reccommendation, from all my health carers to avoid the complications from diabetes (which can be aweful), was to eat mostly healthy whole foods and have a regular excercise routine. I'm pleased to report that they have been correct and as a result I have been able to live a reasonable, normal life.
Best Wishes
