Congrats on taking this big, scary step! It is very overwhelming, but we're here to help.
Are you having the colon attached to the rectum in the same surgery or having more surgeries? If it's the same surgery, then you wouldn't have an ostomy bag at all, right? It's just helpful to know what surgery before giving advice.
I think what you're referring to is a belly band, which some people wear to give some extra support for an ostomy bag.
Some of the first advice that people on this list like to give is "walk, walk, walk" and then "chew, chew, chew." After surgery, as soon as you can walk, the nurses will probably be making you walk, and you probably won't feel like it and will be amazed at how hard it is, but just do it..... it gets easier fairly quickly and it makes you feel a LOT better. You'll also be happier if you have your own slippers to walk in and robe to wear.
And chew your food really well at first to avoid any kinds of blockages etc. At first you won't be able to eat, and your output will be green and slimy and smelly, but it gets better.
With lapro surgery the gas goes into your shoulder and it's a weird sensation for a few days afterward .... just unexpected. They also gave me this tube I had to blow into to make a ping pong ball go up and down.... it was to exercise my lungs after the anesthesia (you're under longer w/a lapro surgery, but it's worth it, especially w/your allergy) and it was good to do that.
Those are a few thoughts, others can add more. Feel free to ask more specific questions as they occur to you.
