The severity of
ulcerative colitis is determined by certain criteria.
Ulcerative colitis can be classified as mild, moderate, or severe, which may
guide treatment choices.1
People who have mild ulcerative colitis may
have:
- Fewer than four stools per day.
- No
bleeding or a small amount of bleeding with stools.
- Normal or mild
elevation of erythrocyte sedimentation rate (ESR).
People who have mild ulcerative colitis do not have fever, rapid
heartbeat, or
anemia.
People who have moderate ulcerative colitis
have:
- More than four stools per
day.
- Cramping abdominal pain and an urgent need to have a bowel
movement.
- Mild elevation in erythrocyte sedimentation rate.
People who have severe ulcerative colitis
usually:
- Have more than six stools per day (constant loose
stools).
- Have frequent bleeding from the rectum.
- Have
fever, rapid heartbeat, and anemia.
- Have an elevated erythrocyte
sedimentation rate.
- Feel very ill.
Flare-ups can be so severe that they require hospitalization.
