What section does anal bleeding see when defecating

If there is anal bleeding during defecation, you should go to the anorectal department for treatment. There are many reasons for hematochezia. If the color of hematochezia is dark red, it may be upper gastrointestinal bleeding. If the patient has a history of gastric and duodenal ulcers, gastroscopy should be actively performed. Sometimes gastric and duodenal ulcers will cause bleeding. If hematochezia is present, it may be caused by small intestinal polyps or small intestinal diseases. If necessary, small intestinal capsule endoscopy will be performed to clarify the cause and then active treatment. If the patient has intestinal cancer, the stimulation of the cancer will also cause hematochezia, bright red or dark red, sometimes accompanied by changes in bowel habits, which can be clearly diagnosed by colonoscopy. If the hematochezia is bright red, it may be caused by anal fissure or hemorrhoids, which can be diagnosed by anoscopy.
