Had my first stoma operation in 1992 when I was 20 after 2 years of pretty horrific CD symptoms. Even though I have since had problems with two abcesses over the years and few flare ups it has made a massive positive difference to my life. Even during a flare up when the bag is filling really quickly, not having that butt clenching urgency to rush to the bathroom is amazing.
I could feel the difference as soon as I can round from the operation. I felt so good after have 2 bad years I was back to work after 3 weeks, prob not best idea but put it down to exuberance of youth!!
Best wishes and agree with others who said to check out all the appliances available. I didn't know there were so many until 3 years after my surgery, then again times have moved on since then. I now use a two piece system, the flange has a extra piece of adhesive covering so if overnight the bag goes nuts and fills so much it gets slight leakage, I have some extra time before it breaches the second adhesive layer. But it is trial and error as what suits you best.
