I had pancreas, spleen, and gallbladder removed in July. I have a great appetite, but 3-4 diarrhea bowel movements per day now. I take Immodium. And also Creon. Not sure if my bowel issues are due to certain foods (high fat, processed, fried) and lack of gallbladder. But from what I've seen, diarrhea is very common following pancreatectomy and can last quite a while, if not forever.
