Hi! i am suffering from ulcerative colatis since nov-11 and got flare in Jun-12 and May-14. Currently on medication of Mesacol 800mg (3times a day) and Azuran 50mg once a day. I am having lower abdomen pain for last 4 months and lost 12 kgs appx and got investigated for Appendix, TB, Gyno problem, Urine infection but all reports are normal. A week back got colonoscopy done and UC is in remission stage. What can be reason for pain and weight loss?
Hello, Ok, flares are normally pretty obvious when they are occurring. Malabsorption or flare would produce diarrhea and not in a subtle way.  In theory, there can be an overgrowth of gut bacteria causes loss of weight and pain. Frankly, most other causes would be pretty obvious even without the colonoscopy.  While colitis is predominantly LARGE bowel, involvement with the absorptive area of the small bowel either with UC or with bacterial overgrowth isn't seen on the colonoscopy. Hope I have answered your query. Let me know if I can assist you further. Take care Chat Doctor.
