- You cannot eat for eight to 12 hours.
- You will undergo a bowel cleansing with a laxative (similar to what is needed before colonoscopy).
The goal of this laxative cleansing is to get rid of all the stool in your colon. The laxative will cause you to have many bowel movements over several hours.
If you have diabetes, discuss your medications with your doctor.
No sedation is needed for the procedure.
