  • Fewer than four bowel movements (stools) a day.
  • No bleeding or a small amount of bleeding with stools.
  • Normal erythrocyte sedimentation rate (ESR).

People who have mild ulcerative colitis do not have fever, rapid heartbeat, or anemia.

  • More than four stools a day.
  • Mild elevation in ESR.

People who have severe ulcerative colitis may have:

  • More than six bloody stools a day (loose stools).
  • Fever, rapid heartbeat, and anemia.
  • An elevated ESR.

People who have fulminant ulcerative colitis may have:

  • More than 10 stools a day (loose stools).
  • Constant bleeding from the rectum.
  • Fever, rapid heartbeat, and anemia.
