If the stool keeps bleeding, first of all, you should not be nervous, you should make the patient lie flat on the bed, monitor his vital signs, monitor blood pressure, pulse and body temperature. There are many reasons for stool bleeding, it may be internal hemorrhoid bleeding, it may be vascular bleeding due to rectal injury, or it may be bleeding due to rectal polyps or rectal malignant tumor invading blood vessels. If the bleeding is relatively large and fast, we should go to the hospital promptly. In addition to monitoring the vital signs, intravenous rehydration should be given, routine blood tests should be performed to clarify the degree of anemia, and anoscopy should be performed to clarify the bleeding site and the nature of the bleeding. If the bleeding location is high, colonoscopy should be performed in a timely manner after the vital signs have stabilized. If the bleeding site is found, hemostasis should be given in time or necessary surgery should be performed.
