Glycerin suppository--does it just affect the rectum and lower sigmoid colon (stimulation and water)? Or does it affect the rest of the colon?

1 doctor agrees

In brief: Just rectum

Glycerin is an irritant stimulant.
It only affects the area it comes in contact with. However, by relieving a blockage in the rectum, you may be able to fully empty your colon, especially if you have used a stool softener by mouth.
