feelfine, from what you've written, you've only recently been diagnosed with UC so I thought I'd offer a different opinion to those mentioned earlier.
I would personally delay having surgery until I have exhausted ALL other options and given them enough time to work.
Though surgery should 'cure' you of UC, there are no guarantees that everything will go smoothly and other complications post-surgery may arise down the road. This is a very personal decision to make but I would advice that even after speaking with your GI specialist and a surgeon, get second opinions from another surgeons and GI specialists about the way forward.
I've dealt with several GI specialists and found that each one offers somewhat different solutions to the issues we're dealing with.
All the best.
