Summary
An enema, also known as a clyster, is an injection of fluid into the lower bowel by way of the rectum. The word enema can also refer to the liquid injected, as well as to a device for administering such an injection. In standard medicine, the most frequent uses of enemas are to relieve constipation and for bowel cleansing before a medical examination or procedure; also, they are employed as a lower gastrointestinal series (also called a barium enema), to treat traveler's diarrhea, as a vehicle for the administration of food, water or medicine, as a stimulant to the general system, as a local application and, more rarely, as a means of reducing body temperature, as treatment for encopresis, and as a form of rehydration therapy (proctoclysis) in patients for whom intravenous therapy is not applicable. The principal medical usages of enemas are: As bowel stimulants, enemas are employed for the same purposes as orally administered laxatives: to relieve constipation; to treat fecal impaction; to empty the colon prior to a medical procedure such as a colonoscopy. When oral laxatives are not indicated or are not sufficiently effective, enemas may be a sensible and necessary measure. A large volume enema can be given to cleanse as much of the colon as possible of feces. However, a low enema is generally useful only for stool in the rectum, not in the intestinal tract. Such enemas' mechanism consists of the volume of the liquid causing a rapid expansion of the intestinal tract in conjunction with, in the case of certain solutions, irritation of the intestinal mucosa which stimulates peristalsis and lubricates the stool to encourage a bowel movement. An enema's efficacy depends on several factors including the volume injected and the temperature and the contents of the infusion. In order for the enema to be effective the patient should retain the solution for five to ten minutes, as tolerated. or, as some nursing textbooks recommend, for five to fifteen minutes or as long as possible.

Laxative
Laxatives, purgatives, or aperients are substances that loosen stools and increase bowel movements. They are used to treat and prevent constipation. Laxatives vary as to how they work and the side effects they may have. Certain stimulant, lubricant, and saline laxatives are used to evacuate the colon for rectal and bowel examinations, and may be supplemented by enemas under certain circumstances. Sufficiently high doses of laxatives may cause diarrhea. Some laxatives combine more than one active ingredient, and may be administered orally or rectally.
Naturopathy
Naturopathy, or naturopathic medicine, is a form of alternative medicine. A wide array of pseudoscientific practices branded as "natural", "non-invasive", or promoting "self-healing" are employed by its practitioners, who are known as naturopaths. Difficult to generalize, these treatments range from outright quackery, like homeopathy, to widely accepted practices like certain forms of psychotherapy. The ideology and methods of naturopathy are based on vitalism and folk medicine rather than evidence-based medicine, although practitioners may use techniques supported by evidence.
Constipation
Constipation is a bowel dysfunction that makes bowel movements infrequent or hard to pass. The stool is often hard and dry. Other symptoms may include abdominal pain, bloating, and feeling as if one has not completely passed the bowel movement. Complications from constipation may include hemorrhoids, anal fissure or fecal impaction. The normal frequency of bowel movements in adults is between three per day and three per week. Babies often have three to four bowel movements per day while young children typically have two to three per day.
