Both constipation and diarrhea are symptoms of UC; so are fevers, vomiting, nausea, abdominal pain, and a host of maladies. The first 10 years of my UC were all about constipation, a trigger flipped in year 10 and then I suffered with 2.5 years of chronic diarrhea. I also had fevers and vomiting in the last 2 years before surgery. During my entire UC history I never once had abdominal pain as a symptom. My GI could not believe, based on my scope and symptoms, that I had zero pain. We are all affected differently with this disease.
