what is an enema used for

An enema is a process where fluids are injected into the rectum to cleanse the colon, stimulate defecation, or administer medication. Enemas are used to relieve constipation and cleanse the colon. Constipation is a severe condition that slows down the movement of your stool. It also makes the stool hard and difficult to excrete. It can become a chronic problem for many people and requires treatment, such as enema. Enemas can also treat fecal incontinence, a condition in which the stool leaks from the rectum unexpectedly. They are also used to clean the bowel before any test or surgery. Enemas are available for purchase at pharmacies for home use, but you should ask a doctor or nurse for specific instructions to avoid injury. The two main types of enemas are cleansing and retention enemas, which come in a variety of solutions and can be injected at home. The principal medical usages of enemas are to relieve constipation, to treat fecal impaction, and to empty the colon prior to a medical procedure such as a colonoscopy.
