Which type of enema is often used to soften hard stool?

The oil retention enema is specifically designed to soften hard stool. This type of enema involves administering a small volume of mineral oil, which helps to lubricate the stool and makes it easier to pass. The oil coats the fecal matter, reducing friction and facilitating movement through the intestines. It also helps to hydrate the stool, which can be particularly beneficial for individuals suffering from constipation or impacted stool.

In contrast, other types of enemas serve different purposes. Hypertonic enemas draw water into the bowel from surrounding tissues, promoting bowel evacuation but without directly softening the stool. Saline enemas are effective for stimulating bowel movements and can help with hydration, but they do not specifically focus on softening hard stool. Barium enemas are primarily used for imaging purposes, to visualize the intestines on X-rays, and are not intended for stool softening or constipation relief.
