I am a 50-year-old female. Have had problems with my bowels (diarrhea/loose stools) during several weeks early in 2015 and now it has appeared again from early August and ongoing. Had a colonoscopy done in March which showed no problems. Please find photos of red object attached. Parasite? Part of the bowel? Have also attached a photo of something else that looks odd, that also came out with my stools recently. Could it be a part of a bile duct?
