Am 27 year female. I have hirschsprung disease at my birth. Later I underwent colostomy because of lack of follow up I came with fetal impaction before 2 years to the same doctor he removed it. I have been dulcolax for 2 years regularly but the problem is I can not pass my stool naturally the colon will not push my stool to the bowel when I skip the dulcolax tablet I keep on pushing its only farting. I do not knw what to do.
