What is a colostomy?

A colostomy is a surgical procedure that creates an opening (stoma) for the colon (large intestine) through the abdominal wall. This procedure is often performed after bowel surgery or injury and can be either temporary or permanent, depending on the patient’s medical needs.

How does a colostomy work?
After the surgery, the colon is diverted through the stoma (opening) in the abdomen. Waste products (stool) then pass out of the body and into a colostomy bag or pouch attached to the stoma. Depending on the type of colostomy, this process may be temporary or permanent.

Why is a colostomy performed?
A colostomy is usually performed when part of the colon needs to be bypassed, healed, or removed due to disease, injury, or surgery. Conditions such as cancer, diverticulitis, or inflammatory bowel disease may lead to the need for a colostomy.

Is a colostomy reversible?
A colostomy may be either temporary or permanent:

  • Temporary colostomies (like the loop colostomy) can typically be reversed after the colon has healed.
  • Permanent colostomies (like the end colostomy) are usually done when it is not possible to reconnect the colon.

What lifestyle changes will I need to make after a colostomy?
While adjusting to a colostomy can take time, most people with a colostomy can lead an active life. You’ll learn how to care for your stoma and manage your colostomy pouch. With proper education and support, you can continue to enjoy many aspects of life, including physical activity and social engagements.
