If you are searching for why do people need colostomy bags, you’re not alone. Thousands of Americans receive a colostomy every year to protect their health, allow healing, or prevent life-threatening complications. Knowing the reasons behind this surgery helps reduce fear, bring clarity, and give confidence during recovery.

Ostomy bags are not a setback — they are a medical solution designed to save lives, restore comfort, and give people the chance to heal safely.

What Is a Colostomy Bag?

A colostomy bag is a soft pouch attached to a stoma — a small opening on the abdomen created by a surgeon. To understand why do people need colostomy bags, it’s important to know that a stoma is only created when the colon can no longer pass stool normally or safely.

7 Reasons Why People Need Colostomy Bags

1. Colorectal Cancer

One of the most common reasons why people need colostomy bags. Tumors may block bowel passage or require removal of part of the colon.

2. Severe Diverticulitis

Infections, abscesses, or perforations are major reasons why do people need colostomy bags, often temporarily.

3. Inflammatory Bowel Disease (IBD)

Crohn’s disease and ulcerative colitis can severely damage the bowel, explaining why people need colostomy bags long-term.

4. Traumatic Injury

Car accidents, falls, or surgical complications sometimes damage the colon so severely that this becomes why do people need colostomy bags for safety.

5. Bowel Obstruction

Obstructions caused by tumors, scar tissue, or twisting of the bowel are major reasons why people need colostomy bags.

6. Congenital Conditions in Infants

Some babies need temporary colostomies until reconstructive surgery can be done — another medical reason why people need colostomy bags.

7. Severe Infection or Tissue Damage

If blood supply is lost or infection destroys part of the bowel, surgeons remove the damaged section. This life-saving step explains why do people need colostomy bags.

  • Temporary: when the bowel needs time to rest and heal.
  • Permanent: when part of the colon or rectum cannot safely function again.
