I have to be really honest, although I generally agree with Marianne that I think you ought to just get it over with, but I also have to say... you are in much better health and enjoying a much better QOL than a lot of people when they opt for surgery. Is your signature accurate that you're not even on steroids? I think the only thing you really need to do to "buy time" is eat a "safe" diet (whatever that means for you) and be patient. You might want to look into the low FODMAP diet and try reducing those foods specifically because they are the main culprits for gas production, and it sounds like excess gas is the main problem causing your QOL issues right now.
Are you in the US? My colectomy was elective (not emergency) and it was scheduled in literally five days -- my GI called the surgeon's office on a Friday, and I went into the OR the following Wednesday. She had to make the call on my behalf (the wait time that was quoted directly to me was four weeks, I think) but there is usually a way to get yourself moved up. No matter what you decide about
the logistics you should have your consultation ASAP: it will get it out of the way and the surgeon may have good advice for you as well. Doing it now would make the holidays this year kind of a wash, but as Marianne said, you'll be UC free and can enjoy whatever stuff you want to do with your ileostomy next year, including all your PTO days!
