Colostomy irrigation is the process of passing water through the stoma to manually flush the colon at a given time. This regulates bowel movements and is sometimes referred to as "training" your ostomy. Most ostomates irrigate at a scheduled time. After performing irriation, your stoma could stop producing output for one to two days. Colostomy irrigation offers benefits such as being able to wear a stoma cap and not having to change your pouch as often. Keep in mind that this procedure is not always effective or suitable for everyone. It is important to talk to your doctor or nurse to determine whether ostomy irrigation is right for you.
