When I had my ileostomy (loop), I had some discharge. A few times I even had solid BM as if I still had my colon. I told my surgeon and I don't think he believed me. I wasn't too worried about it since the nurse told me some discharge was just old blood and mucus from the big surgery being expelled, and I was getting nearer to takedown so i was okay with it. I think with the loop ileostomy some food can bypass the exit to the ostomy bag and food will go down into your anal area and be pushed out just like a BM. If you google for a side view of a loop ileostomy, you will see one part of your small intestine leads out of your body ending in your stoma and into your ostomy bag, and the other end leading down and out of your body through your anus. I knew this was my case because I could see things I had eaten, such as spinach, coming out like a solid BM even while I was seeing waste filling my ostomy bag as expected. I also worried it was a leak. But I had no fever or pain. I was just expelling from every opening! When you notice it more from standing or walking around, that is usually what happens when you are active. Remember this is what nurses and doctors will tell you over and over after bowel surgery: get up and walk, walk, walk so that your bowels wake up and start working. I hope you get reassurance from your surgeon, especially if you are experiencing this many times a day and leaking at night. It's good you do not have signs of fever or infection. Each day you are getting closer to takedown and your new life with a j pouch.
