Enemas, such as the well-known Fleet enema, treat constipation by introducing fluid into the intestines through the rectum. The liquid softens impacted stool, while the enema nozzle loosens the rectum. That combination will stimulate a large bowel movement.

What kind of enema is used for impaction?

Treatment for the condition starts with removal of the impacted stool. After that, steps are taken to prevent future fecal impactions. A warm mineral oil enema is often used to soften and lubricate the stool.

What happens if you don't poop after an enema?

What should I do if I administer an enema and it does not work? If there is no bowel movement after 5 minutes of using, try to empty bowel. Call a doctor promptly after using a saline enema and no liquid comes out of the rectum after 30 minutes, because dehydration could occur.
