What is a colostomy bag?

A colostomy bag is a bag that attaches to the abdomen and collects waste from the body following a colostomy procedure. This surgery creates an opening in the abdominal wall through which stool exits the body, according The National Institute of Diabetes and Digestive and Kidney Diseases.

Colostomy bags are also called stoma appliances. Colostomy bags are closed at the bottom and are designed to contain odor when in place, according to Ostomy Lifestyle. Individuals who undergo colostomy procedures are usually required to wear colostomy bags because stool and gas drain at unpredictable times. Change a colostomy bag approximately one to three times per day, following each bowel movement.
