If you need to have a bowel movement after drinking electrolytes, the extent to which you need to have a bowel movement depends on the examination. If a colonoscopy is required, a bowel movement is required until there are no formed stools at all, that is, after drinking electrolytes, a certain amount of movement is required to make the electrolytes vibrate in the body and cause the stools to be discharged by the principle of osmotic diarrhea. In this case, at least 6-8 bowel movements should be performed, and the stool should be basically free of formed material. The presence of watery stool, watery stool or watery stool in the stool proves that the intestines have been basically cleared, and only then can the colonoscopy be performed.
