The most accurate way to check for bleeding after surgery for intestinal polyps is to perform a colonoscopy as well as a routine stool examination. Generally, postoperative patients may have darker colored stools due to minor intestinal bleeding, and if the bleeding is severe, bloody stools may be present. However, to clarify whether postoperative bleeding has occurred, colonoscopy as well as routine fecal examinations are required. After the surgery of intestinal polyps, because of the slight damage of intestinal mucosa, it is possible to have postoperative bleeding, but the bleeding is usually not serious, the patients themselves have no clinical symptoms, and only find that the color of the stool becomes darker, and the bleeding can be stopped within 3 days. However, some patients may have red blood in the stool, accompanied by clinical symptoms such as dizziness, fatigue, and hyperactive bowel sounds, which require further examination and appropriate treatment. Symptoms alone can not be a good judge of the patient’s specific situation, usually need to carry out relevant tests such as colonoscopy and stool routine to clarify the presence of bleeding, such as a small amount of bleeding, can be observed, such as a large amount of bleeding, the need for further examination and treatment. It is recommended to consult a doctor in time when symptoms occur, do not be negligent, so as not to delay the condition.
