bull4t,
Welcome to the forum.
I am so sorry that your proctitis has spread into UC.
WHat had put you in remission from the procticis?
And have you been on meds (if so which ones) all this time?
IMO, if you are proactive and control various factors, you could get this under control. It's not a given that UC progresses further.
Are you on any probiotics?
Any supplements?
What are your vit. d3 levels like?
