Enema Indications

Stubborn constipation: A small enema is performed to trigger the stool evacuation reflex. Another possibility in case of failure, the enema is more voluminous, (a few hundred milliliters), with salt water for example. It is used to rehydrate the materials located high enough in the colon and to make the stool evacuation reflex effective.

Therapeutic enemas: They are used in the lower locations of ulcerative colitis, and contain a corticosteroid.

Exploration of the large intestine: the simple barium enema or barium enema with double contrast are two x-rays which make it possible to precisely show the interior contour of the intestines.

How does enema happen?

The small enemas contained in a squeeze bottle are injected directly into the rectum.

Larger enemas use gravity: the bottle is connected to a flexible tube, placed above you, the height determining the force of penetration of the liquid.

Enema Complications

Executed normally, there is none.

Too high enemas carried on a stubborn constipation, can favor a perforation of the wall of the colon. This is the risk in the event of an obstacle on the colon or in the event of diverticulosis . This kind of enema should never be practiced in self-medication, it is a doctor who must prescribe it.
