The symptoms of ulcerative colitis vary. Some people with the disease have a burst of symptoms every few months. Others have symptoms either all the time. Some, fortunately, have symptoms only rarely.

Typical symptoms include:

  • Cramping abdominal pain, especially in the lower abdomen

  • Bloody diarrhea, often containing pus or mucus

  • Little warning before you need to have a bowel movement

  • The need to wake from sleep to have bowel movements

Ulcerative colitis also may cause:

  • Fever

  • Fatigue

  • Decreased appetite

  • Weight loss

  • Loss of fluids that can lead to dehydration
