bulky or high-fiber foods tend to "push" out stool. stools of these bulky consistencies typically will not bypass an impaction and could actually make an impaction worse. if you truly have an impaction it would be best to get specific orders from your medical provider on the best way to treat this. treatment may range from mineral oil to enemas to cleansing laxatives/cathartics pending on your medical history and extent of the impaction.
does a high fiber diet actually clear an impacted colon? or just cause the fresh bms to go around the impacted waste?
