What are the three most common reasons for performing a colostomy?

Performing a colostomy is primarily indicated for conditions that necessitate the rerouting of intestinal contents due to disease processes or significant bowel dysfunction. The correct answer highlights three conditions that are commonly associated with the need for a colostomy.

Cancer is a leading reason for colostomies, particularly colorectal cancer, where the tumor may obstruct the bowel or require resection of a part of the intestine. In such cases, a colostomy may be needed to create a new opening for waste elimination.

Diverticulitis, an inflammation or infection of small pouches that can develop in the walls of the colon, can also lead to complications such as perforation or abscess formation. If these complications arise or if the condition is recurrent, a colostomy may be performed to allow the colon to heal and to manage the patient's bowel function more effectively.

Ulcerative colitis is another inflammatory bowel disease that can cause severe damage to the colon, leading to bleeding, ulcers, and increased risk of colon cancer. In cases where conservative treatments fail or significant complications arise, a colostomy might be necessary to prevent further harm and improve the patient’s quality of life.

Each of these conditions is directly related to significant issues within the gastrointestinal system that
