In several studies, through results of colonoscopy and histopathology, it was found that the most common cause of chronic diarrhea was non-neoplasm, including IBD, microscopic colitis as a risk factor, and infectious colitis as a differential diagnosis. Each of those diseases has similar symptoms, but different pathological description.
