I think the question focus is if one is originally diagnosed with ulcerative pancolitis (complete colon involvement)...is that always the "diagnosis"?
In one word ... yes...healing doesn't make the disease cured from the original site. It can be controlled, however having flares limited to the lower part of the rectum....being a current status rather than a new diagnosis.
UC can spread from an original diagnosis site if it's limited....not for all, but for many.
There are many with an original UC diagnosis where it's eventually changed to CD. That's because of a misdiagnosis where the CD mimics the pattern of UC...especially in the early stages....until it becomes more advanced it seems to be more obvious.
I must also point out that some doctors aren't good doctors.
Some patients misunderstand the diagnositc term "colitis"...assuming it's UC.
There are also other bowel infections and diseases that mimic UC...one can have UC with other infection or disease..so, for some, diagnosis can definitely change..

My doc's logic.. "TREAT (FROM)BOTH ENDS" worth it !!!
