Is it true that old stools can cause encrustation of the large intestines walls?
No, they can’t, unless you are reading a deceptive advert for a ‘colon cleanser’ or ‘colonic therapy.’ It is pointless to enter into a debate with quacks and charlatans behind this gimmick, except to point out that you can’t bind a ‘crust’ to the mucosal membrane inside the colon for the same reason that food can’t form a crust inside your mouth.
