Question: My colonoscopy revealed colitis but dr. says it is not ulcerative colitis. I am having a stomach full feeling even when I don't take food. Passing stools is very difficult and it is always a feeling of incomplete bowel evacuation (for over 15-20 years now.) At present I am using normaxin twice or thrice a week. I get relief only for a few hours after I take the medicines but the symptoms recur. Fail to understand whether the problem is in bowel or stomach or in small intestines. Ultrasonogram revealed there is no abnormality.

Biopsy was also performed with colonoscopy (Sept.2010). It reads " biopsies from rectum and transverse colon. Both biopsies reveal similar histology. Mucosal crypts are uniform and parallel. Lamina propria is expanded, edematous, congested and densely infiltrated by lymphocytes, histiocytes. Stromal hemorrhages are seen, however there is no mucosal necrosis or hemosiderin pigment. There are no characteristics changes of ulcerative colitis. Impression : Chronic colitis with stromal hemorrhages". The bowel movements are very slow and there is always feeling of incomplete bowel evacuation, even after spending 1-2 hours in toilet in 2-3 visits in the morning.
I used the medicines prescribed by doctor (welgut, mesacol etc.)but unfortunately there is little relief. The symptoms are continuing and are I am afraid, worsening. An earlier biopsy said "possibilities of ischemic bowel disease can't be ruled out".
Kindly suggest useful medicines or further diagnosis if needed.
