Important difference between Caron's and u.c. Is that in u.c the inflammation is continuous throughout the colon but is only mucosa deep. Whereas in crown,s inflamed parts are separated by normal mucosa (patches). Also, crohns involves mucosa as well as sub mucosa. Another big difference is that small intestine or ileum is also affected in crohn,s. In u.c. ,rectum is involved whereas in crohn,s rectum is not involved. That's why you see fresh blood in stools in u.c but you don,t see fresh blood in crohn,s. As for, Ulceris. It is fundamentally a. Steroid which only releases in colon and thus has less side effects. Ulceris is not used more than 8 weeks and is not a maintenance medicine.
Diva2014, there are a few misleading/incorrect descript
ions in your reply regarding some of the differences between Crohn's Disease and Ulcerative Colits...
Crohn's can affect any part of the GI tract from mouth to anus, therefore the rectum can very well be involved (I have scaring in mine, I have Crohn's) and you certainly can see "fresh blood" in crohn's just as you can in UC when Crohn's is affecting the colon (crohn's colitis) and/or affecting the rectum as well. UC is limited to the colon/rectum...
Crohn's can also affect more than one part of the GI tract at the same time, making it harder to treat.
Crohn's can go deeper into the intestinal lining (which can also make it harder to treat) where as UC stays on the surface only, but with Crohn's it doesn't necessarily always go deeper. Crohn's is patchy inflammation, with UC the entire area involved will be inflamed with no patches of healthy tissue.
There are 5 subtypes of Crohn's disease because Crohn's can affect any part of the GI tract from mouth to anus (and can affect more than one area at the same time). Crohn's doesn't always affect the small intestine, which is why there are 5 subtypes of Crohn's disease, to help break down the most common areas in the GI tract that Crohn's typically can affect.
Many of us that suffer with crohn's colitis don't always have rectal involvement but when Crohn's is affecting the colon the risk of rectal involvement can increase the risk of Crohn's affecting the rectum.
Crohn's typically starts in the small intestine but it's not written in stone, my Crohn's started with perianal crohn's skin tags on the anus well before it ever started to affect me intestinally.
