Basically, UC starts at the anal/rectal junction and continues it's inflammation upward. For some, it's limited, some it's throughout.
Many of us don't suspect inflammation with constipation....which can also be a symptom of IBS...but once bleeding, rectal pain and urges but with blood or mucus..it's suspected that something else could be going on.
If the inflammation continues upward to the top of the rectum, one could have more bms, looser or soft, pencil thin...or up to loose to the point of diarrhea.
Once it gets past the top of the rectum, the stools are more diarrhea.
Now...depending on the amount of inflammation, there will be no blood or blood, more bms, less bms..etc. Some don't have symptoms to match the degree of inflammation, meaning...some with more severe inflammation might not have as many symptoms as someone with slight inflammation...we all do tend to present similar, but with variations.
Healing tends to go the opposite way. Think of a thermometer...up and then down. As one heals, the symptoms will change with rectal symptoms the last and the most stubborn for some.
But, basically....if you are having less bms, with bleeding and mucus, I would think it's still a flare, but improving.
If you are taking imodium or meds that can cause the colon to slow down, you might have higher inflammation, but it's masked by the change in colon function by the meds..not by the place of inflammation.
Now, I'm going to cover my butt here and state that it seems a low number of patients don't have rectal involvement...but possibly they have CD in early stages or indeterminent colitis. Time can tell eventually.
I'm basing ,my suggestions and knowledge on the norm UC diagnosis and that you have rectal involvement considering you're on Canasa.
Hope this helps.
You should, however, still consider either a stool softener or to try the Metamucil Smooth....the reason is that a soft stool feels much better going through an inflamed rectum.
