What is collitis?

Colitis: There are too many causes to list here. Ulcerative colitis and crohn's colitis are much more treatable now than before. Infectious colitis (salmonella, shigella, amoebas) may need to be screened for and treated if found. Some physicians call irritable bowel syndrome / spastic colon "colitis"; it's a disease with a physical basis but only manageable symptomatically. Good luck.

Colitis: Inflammation of the colon from a number of causes. From colon and itis - inflammation.
