Hi - I started out with moderate-severe UP in 2005 and my last scope showed ulcers and inflamation had spread about
15 inches up in the colon.
Of course, my result may be from not taking this disease seriously and not taking my prescribed meds or seeing my GI. I am making up for it now though.
Also I have read on this board numerous times that having severe protitis is often harder to deal with than having mild colitis farther up and that there is percentage of protitis sufferers whose colitis never spreads beyond the rectum.
