Scheduled colonoscopy today, but I'm still passing brown fluid and some debris. Followed all instructions, 40 hrs no food, will they reschedule?

Scheduled colonoscopy today, but I'm still passing brown fluid and some debris. Followed all instructions, 40 hrs no food, will they reschedule?

Probably OK.: As long as what you're passing is a liquid, it will probably be OK to proceed with the procedure.

Ct scan of the abdomen/pelvis can help make the diagnosis.After you feel better, and the infection resolves , a colonoscopy is indicated to further evaluate the colon. ...Read more
