What is a Colostomy?

A colostomy (which is one type of stoma or ostomy) is the result of an operation where part of the colon (large intestine) is brought out onto the surface on the abdomen. 

Food waste exits the body via the colostomy rather than from the anus. This waste is collected in an appliance that is worn on the abdomen, over the colostomy. These appliances are usually referred to as stoma bags.

A colostomy operation might be done because a section of bowel has had to be removed due to bowel cancer, inflammatory bowel disease, or injury.
