I have tried high dose magnesium, metamusil, mineral oil, senekot, milk of mag. and nothing makes her poop. She is in the emergency room with rectal prolapse 3 times now. The only way I have been able to get her to poop, is to give her culturelle one night and skip the next night. She then poops. It is not the culturelle making her constipated 'cause she was constipated before this. We suspect clostridia and we are about to start vancomycen soon. (She's already on the amphoceterin.) My thought was that she is constipated from all the bad bacteria not being killed and pushed out, but I am not so sure about that. I just don't get why stopping and starting the culturelle makes her poop. Any ideas???
