I agree with many of the comments others have made... surgery's never perfect, the colon serves an important purpose, removing it doesn't guarantee a life of health and happiness, etc. For every person who's come on here with a happy story of quick recovery and freedom, there's probably one or two others who've had complications, misery and immune problems cropping up elsewhere.
Removing a major organ just isn't a positive, healthful solution to me, unless there's no other choice. I hated being told, "You've got a chronic disease. You'll never be well. You'll remain on medication until you get sick enough to have your colon removed," as my first GI told me. I may have a chronic health condition that needs to be managed and adapted to (similar to being diabetic), but I am NOT constantly sick or disabled. In fact, I've been pretty much in remission for years with only minor upsets. Rather than viewing my colon as the problem, I wanted to discover the many causes and triggers of IBD and attempt to remove them. Rather than taking powerful immunosuppresants, I decided to look at other natural approaches that would build up my body, balance my gut ecology, remove offending foods, and try to improve my health rather than suppress (or remove) the symptoms. Is it a miracle cure? No. Is it fast and easy? No. Does it require alot of research, trial and error, sacrifice, changes in lifestyle? Yes. Is it worth it to me to be mostly symptom-free and have all my organs intact? For me, yes.
