What does interstitial in colitis mean?

Interstitial in colitis refers to inflammation occurring in the interstitial spaces of the colon, which are the areas between the cells and tissues. This type of colitis can indicate a more diffuse inflammation rather than localized damage. Interstitial colitis may be associated with various underlying conditions, including infections or inflammatory bowel diseases. It is characterized by symptoms such as abdominal pain, diarrhea, and changes in bowel habits.
