Postoperative colon polyps may cause bleeding from the local trauma due to the friction of feces. If the amount of bleeding is relatively small, there is no need for special concern or special treatment. You can improve your diet and avoid eating foods with very coarse fibers, such as bamboo shoots and dried bamboo shoots. If the amount of bleeding is large, or even if there are clots in the discharge, you need to go to the hospital promptly and perform colonoscopy to clarify the site of bleeding. The bleeding can be stopped by spraying hemostatic drugs under the microscope or by applying titanium tongs to the wound surface. You should eat liquid or semi-liquid food for 72 hours after colon polyp surgery to prevent bleeding, infection, perforation and other symptoms.
