I went the colostomy route for 6 months but not by choice. I had that surgery due to severe C that wouldn't respond to anything else. It was a shock, although they told me what to expect and I thought anything had to be better than the pain. But it took me weeks to recover, not so much from the surgery but from the mental shock of what all a colostomy entailed. Actually I don't know how long it would have taken me to recover mentally because three weeks after the semi-emergency surgery for the C, I was back in the hospital for a second surgery due to adhesions of the small intestine to the large intestine from the first surgery (which I understand is not all that uncommon). That was such a shock that the colostomy actually took a back seat to trying to recover from two major surgeries in a month.
I then had several hospitalizations after the colostomy reversal (due to C) and at times would think maybe I should just have a permanent colostomy, but then I would remember the inconvenience of it all and that lead me to research and finding this website.
I know my problem is C and yours is D but I would really be cautious of making that decision. If you want more information about what life with a colostomy is like you can email me. My insurance did not cover the supplies even though the surgery was a medical neccesity, and the supplies are expensive.
