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:
Loss of fluids that can lead to dehydration
