Hi, Wagsam,
Like Vikinga said, each journey is different. For me, I had a few years of typical Crohn's symptoms including abdominal pain, couldn't hold food down, diarrhea, fistulae etc. I was on all kinds of meds including prednisone (which is really bad for you ... bones, for one).
When the doctors went in (surgery), they immediately saw the dying part of my intestine and removed it. They put in an ostomy.
The payback was immediate. My symptoms were a lot better. I took to the bag pretty well. I just had to learn my new-normal.
Through the years, I have had a few repeat performances of my Crohn's/surgeries. But the surgeries have worked.
I hear that some of the meds they use today are better perhaps if I took them in the first place, I would have more intestine. You always want to keep as much intestine as you can.
Since I have been an ostomate, I have run marathons, had hanky-panky, swum oceans etc. etc.. I see you have had a lot of health problems so I imagine this one is no worse than anything else.
Anyway, I am not exactly sure what you were asking for when you wanted the process of an ostomy - i.e, how it gets put in? lifestyle with one? But I figured I'd at least make a connection. If you are more specific with your question, I bet you will get more responses. The people on this forum are great. They represent a lot of experience, and ideas. They approach things in a multitude of different ways (i.e., eastern vs western medicine). But you will not be short of input ... and friends here.
Good luck,
