Doctor's Notes on Colitis

Colitis refers to inflammation of the lining of the large intestine (large bowel or colon). There are a number of different causes of colitis. Some types of colitis include: 

  • infectious colitis, 
  • inflammatory bowel disease (ulcerative colitis or Crohn’s disease), 
  • microscopic colitis, and 
  • ischemic colitis, in which tissue death occurs due to a reduction in blood supply to the colon.

Symptoms of colitis arise due to the inflammation present in the bowel wall. Signs and symptoms include:

  • abdominal pain
  • abdominal cramping, 
  • diarrhea, and 
  • blood in the stool (either visible to the naked eye or detected by a laboratory test). 

Depending on the cause of the colitis, other symptoms can occur. Associated signs and symptoms may include:
