Your prep is one of the most important parts of your colonoscopy. Without a good prep—your bowel empty and clean—your gastroenterologist will not be able to see your colon clearly. This could lead to missing a polyp or having to reschedule your colonoscopy.
Here are photos that show the difference between a good prep and a bad prep so you can see why it’s essential.
What are the risks of a colonoscopy?
Colonoscopy is a standard medical procedure. Although rare, colonoscopies like all procedures have some risks.
- The instrument may tear the wall of the colon which may require surgery to repair.
- There may be adverse drug reactions or heart/breathing complications.
- Bleeding may occur and is more often a risk when tissue or polyps are removed.
- There may be discomfort during and after the procedure.
