Blood in the Stool

• The presence of blood in the stool is a fairly common symptom of colonitis.
  
  

Abdominal Pain

• A sharp stomach pain that comes and goes in waves and that results in diarrhea--only to occur again afterward--is a sure sign of colonitis.
  
  

Tenesmus

• Tenesmus is defined as the constant urge to have a bowel movement.
  
  

Fever

• As with many infections, colonitis sufferers may experience high-grade fevers and chills. These symptoms are not present in all colonitis cases and depend on the type of infection that caused the condition in the first place.
  
  

Dehydration

• Due to the malfunctioning colon and the presence of diarrhea, many colonitis sufferers may become dehydrated as well.
