Electronic colonoscopy requires laxatives.
The order of entry for electronic colonoscopy is anus → rectum → sigmoid colon → descending colon → splenic flexure → transverse colon → ascending colon → cecum, in order to observe the mucosa of the large intestine and part of the ileum mucosa for the presence of lesions. In order to achieve satisfactory results, diet control and bowel cleansing are required before the electronic colonoscopy. It is crucial to take laxatives to clean the bowel before the examination.
After the intestines are cleaned out, the doctor will not miss any test during the colonoscopy due to the intestinal mucosa being obscured by feces. Therefore, you need to drink a laxative to clean out your intestines for an electronic colonoscopy.
The above examination and medication should be done under the supervision of a doctor.
