An enema kit is used to administer fluids into the rectum to cleanse the colon or stimulate a bowel movement, providing fast relief for constipation or fecal impaction. These kits are also used to prepare the bowel for medical tests, such as a colonoscopy, and can be used for administering certain medications or for colon cleansing. The kits typically include a bag or container for the solution, a tube, and a nozzle, with solutions often containing ingredients like saline or glycerin to soften stool and encourage evacuation.
