An enema is primarily used for what purpose?

An enema is primarily used to clear the bowels by introducing liquid into the rectum and colon. This process can help relieve constipation, prepare the intestine for medical examinations such as a colonoscopy, or cleanse the bowel before surgical procedures. The fluid administered can stimulate bowel movements, making it effective for flushing out accumulated waste material and facilitating a thorough cleaning of the intestinal tract. This ensures that the bowel is empty and reduces the risk of complications during medical procedures.

While enemas can also be used to administer medication or in specific cases for hydration, these purposes are secondary compared to the primary goal of clearing the bowels. The context of an enema's primary use is firmly rooted in its effectiveness for bowel evacuation.
