Colitis and diverticulitis are two chronic intestinal disorders that have similar symptoms. They both affect the colon (large intestines). Colitis is an inflammation of the inner lining of the colon and rectum. Diverticulitis occurs when the diverticula (small pouches) develop in the colon (this called diverticulosis) become infected and rupture. The symptoms of these two conditions are:
Abdominal pain occurs usually on the left side of the abdomen the pain may be mild or severe depending on the severity of the condition.
These are characteristic symptoms of both of these conditions also occurring mostly on the left side of the abdomen.
Frequent lose watery stools that may contain blood is another common symptom of both of these diseases.
These spasms are due to the severe abdominal pain that aggravates the abdominal muscles causing them to react with spasms.
Fever and chills occur in colitis due to the inflammation in the inner lining of the colon.
Fever occurs in diverticulitis because of the ruptured infected pouches.
