A colostomy is a surgical procedure where a portion of the large intestine is brought through the abdominal wall to carry stool out of the body. It may be temporary or permanent and is often needed to treat conditions like cancer, bowel obstructions, or injuries. Potential complications include bleeding, infection, or issues with the stoma like necrosis, retraction, or prolapse. Proper care of the stoma and emptying of the colostomy bag is important for recovery. A healthy diet and lifestyle can be maintained after surgery.
