 [ Symptoms ] can a round object travel up from your rectum into your colon and get stuck [ Disease ] it is an interesting question if an object of any size or shape gets inserted into the rectum it can get stuck or as we like to say in medicine retained due to the strength of the external anal sphincter this is the powerful muscle that enables us to hold in or release stool when an object slips beyond the anal sphincter it can be very hard to get out you might be surprised how many people go to the emergency room each year to have a foreign object removed from the rectum however it is unlikely an object would travel up the bowel and deeper into the colon in the first place peristalsis a rhythmic contraction of muscles along the digestive tract naturally propels the contents of the intestines toward the anus for a foreign object to move against the effects of peristalsis would be akin to a salmon swimming upstream that is not to say it absolutely could not happen i guess never say never wishing you well
