The most frequent post-colonic experience is to have a slight delay in bowel movements and then a resumption of a somewhat larger, easier to move stool.  Sometime if the colon is weak and sluggish, there may be no bowel movement for several days following a colonic.  However, this is not due to the colonic, but rather to the weakness of the colon and should be interpreted as an indication that the colon requires strengthening and healing.  Very infrequently diarrhoea or loose bowels maybe experienced.  This could be due to the extra water introduced into the colon or to the stirring up of toxic waste.  If this should occur, it is usually of very short duration.  However, since severe diarrhoea dehydrates the body, it must be carefully monitored.
