Matt,
Welcome to Healing Well. I'm sorry you've been diagnosed with UC. I hope it's okay if I answer your question, because I was in the same position as you when I was 28. I was newly diagnosed with Crohn's, and the doctor wanted to remove my colon.
I hadn't been sick very long, and I just wasn't ready to go there.
I was determined to try everything before having surgery, which I did for 7 years. I took prednisone, Asacol, Azathioprine, antibiotics, and Infliximab, and went on a vegan and gluten free diet. I would have a couple of good months, but then my colon would flare up again. It was a nightmare roller coaster that I wouldn't wish on anybody.
I developed fistulas, which is when the disease burrows a hole from the colon to another part of the body. Those caused me to develop abscesses, and four GI doctors told me that I had to have a temporary ileostomy to bypass the colon to let it rest and hopefully heal.
Much to my surprise, I liked having an ileostomy! I could live my life without having to know where the nearest bathroom was. I could also sleep 8 hours through the night, which I hadn't done in years. I got my energy back and was able to enjoy life again.
After 8 months with an ileostomy, my colon started bleeding nonstop, even though I wasn't using it. That's when I realized that it wasn't going to heal, and I decided to have it removed. I've never regretted that decision for one second. Looking back, I probably should have had the surgery right away, but I needed to know that I tried every other option first.
I hope the medicines start working for you soon. Medicines, when they work, can put you into short term or long term remission, but surgery is a cure, meaning it's gone forever.
Good luck with your decision.
