Soap enemas may also cause chemical colitis. [1] Harsh chemicals, such as compounds used to clean colonoscopes, are sometimes accidentally introduced into the colon during colonoscopy or other procedures. This can also lead to chemical colitis.

Microscopic colitis refers to two related medical conditions which cause diarrhea: collagenous colitis and lymphocytic colitis. [2] [3] Both conditions are characterized by the presence of chronic non-bloody watery diarrhea, normal appearances on colonoscopy and characteristic histopathology findings of inflammatory cells.

A new study in Gut found that colon cancer tumors have an imbalance of inflammatory and anti-inflammatory lipids, which suggests that chronic inflammation could raise the risk of colorectal cancer.
Collagenous colitis is an inflammatory condition of the colon. Together with the related condition lymphocytic colitis, it is a subtype of microscopic colitis, which is characterized by inflammation that specifically affects the colon (i.e. colitis), and a clinical presentation that involves watery diarrhea but a lack of rectal bleeding.
