I had UC for 6 years. Severe endometriosis for years before that which resulted in a total hysteroectomy 4 years ago. I was sooo much better after this that I thought things would be okay now. Unfortunately not. Each spring my UC would flare (loose 25-35 pounds, a month on the couch, living in the bathroom) and each time it flared it would take more and more meds to get it to calm down. This spring, no flare. Instead it waited until August. Nothing calmed it down, so surgery was my only choice.
Surgery is not fun. There can be many complications. The bag isn't that bad, especially if the placement is a good fit for you and you have some great nurses. When you decide that surgery is an option, talk to people openly and you will be amazed at how many people have gone through this. Be sure that you are ready for a change in symptoms. Things aren't always better, but they are different.
Think long and hard about what you want and EDUCATE yourself. There are many great web-sites with straight information. Personally this web site is the most helpful one I have found. The people here really do give honest answers and are very supportive.
As for the point I'm at, I have my colon removed 8/15, had my j-pouch made 11/23 and will hopefully have the plumbing connected in May. I had to have it in 3 steps because I was on so many meds and in such bad shape.
My UC pain is gone, thank goodness, but my loop ileostomy gives me constant problems and is uncomfortable. But compared to the pain I was in, it's not bad.
This decision needs to be one you make and can live with.
Good luck.
