What disease requires a colostomy bag?

A colostomy bag is often required for individuals with conditions that affect the large intestine, such as colorectal cancer, inflammatory bowel diseases like Crohn's disease or ulcerative colitis, or severe diverticulitis. These conditions may necessitate the removal or bypass of a portion of the colon, leading to the creation of an opening (stoma) in the abdominal wall for waste elimination. The colostomy bag collects stool from the stoma, allowing for proper waste management outside the body.
