Just to clarify the use of symptoms to diagnose inflammatory bowel conditions. You know that you have passed from Ulcerative Colitis into Crohn’s when in addition to urgent diarrhea and blood in your stool- you find mucus in your stool. The mucus represents your body’s last ditch effort to protect you from your stomach acids devouring your intestines/colon. This means you are loosing the battle- fast. Next stop-surgery. Don’t fiddle around- you gotta get this fixed!
