There are several reasons why your doctor might recommend an enema. They can help if you're experiencing severe constipation because they can stimulate your bowels to pass stool. Your doctor might prescribe an enema if you're going to have bowel surgery. If you're having bowel surgery, you'll usually need to do the enema around 2 hours before the procedure. If your doctor thinks you'd benefit from doing an enema at home, ask them to prescribe a specific type. They should also tell you how much liquid to use and how often to perform the enema. It's important to closely follow your prescription because frequent enemas can damage your colon or lead to dependence on enemas. It's important to use sterile tools for each enema. You can purchase a kit that contains a sterile enema bag and tubing with a nozzle. Depending on the kit, it may also include a lubricant. You can buy enema kits at pharmacies, medical supply stores, or online. . Hang the enema bag on a hook about 12–18 in (30–46 cm) above your rectum or have someone hold it at this level for you. Positioning the enema bag this way will allow the fluid to flow freely. Rub the skin around your anus and the nozzle of the enema tube with anal lubricant or petroleum jelly. Lie on your side and bring your legs up towards your chest. Then, insert the nozzle into your anus until it's about 3 inches (7.6 cm) deep and release the clamp that's on the tube. The solution will start to flow into your bowels. If you're having trouble inserting the nozzle, try bearing down while you do it. Stay in the same position and wait for at least 5 minutes. Once the enema begins to work, you should start to feel the urge to pass stool. Try to relax and breathe slowly if you feel cramps in your abdomen. If you added glycerin to the solution, you may need to hold the enema for up to 60 minutes. When you feel ready for a bowel movement, go to the restroom and sit on the toilet. It may take some time to expel the enema and pass stool, so don't worry if you're sitting for a while before...
