After recently being back to a temporary ileostomy, I re-discovered that the small intestine can occasionally produce large amounts of very liquid bile and pancreatic juice which can be a fairly bright yellow (or green) colour. I think yellow and green secretions are the natural colours that mix to form brown poop. As I understand it, with the pouch, some of this liquid usually gets reabsorbed, but if your pouch is upset, it's probably passing straight through. I am now back to using my pouch and it's only happened once since. I never figured out what caused these bouts of liquid output - the best I've got is some combination of foods eaten, maybe quantity, timing, bacteria and/or stress levels. You probably know, the main thing is to take extra effort over re-hydration with electrolytes, when you have this diarrhoea.

So now my bowels have been more formed and actually look decent but still are yellow honey mustard in color. Has anyone dealt with this issue with pouchitis? Or has there been an issue with something else for people?

I honestly have no clue what’s going on with me. My stools(without fiber supplement have become more formed and are either like pudding/oatmeal or they come out in little nuggets. That has happened since yesterday. My frequency is up because I seem to not go a little at a time and have a little pressure and gas directly where my vertical incision was about halfway or a little more downs. The stool, although formed well, still has a honey mustard tint to it and no sure why. My thought is my pouch and right about has inflammation(past Friday said severe) so it’s travel time is good throughout my system until it gets to the pouch then it’s not spending much time in there? I am taking imodium. It takes about 3-4 hours until I start to see anything I eat.  My question is, wth could this be? These don’t seem to be typical crohns symptoms. Could it be pouchitis or some sorta bacterial overgrowth in my pouch area that causes the coloration and irritation? I don’t seem to fit nicely into anything I read.  I had diarrhea day and a half after my procedure but since then no problems. I have been eating potato’s, salmon, rolled oats, eggs, chicken, stuff like that.

When I had yellow output it was a problem with my gal bladder. I had some obstruction there that caused high backpain (between the shoulders).

best to visit a doctor, yellow is not a good color for that type of output
