Lower gastrointestinal bleeding needs to be treated surgically to stop the bleeding. When lower gastrointestinal bleeding occurs, a detailed examination is needed to find the cause of the bleeding and to treat it. In some cases, the bleeding is caused by intestinal polyps, which can be removed under colonoscopy, and after surgery, patients need to fast for a period of time and pay attention to fluid supplementation. For bleeding caused by intestinal perforation, the bleeding point needs to be found and promptly treated with surgical repair. Common surgical treatment methods include electrocoagulation and hemostatic clips to stop bleeding. Some people with lower gastrointestinal bleeding are caused by tumor disease, which should be removed surgically in time, and after surgical removal, radiotherapy is also needed to inhibit the spread of tumor. In addition there are some people who develop lower gastrointestinal bleeding due to hemorrhoid disease, for which hemorrhoid disease can be treated with hemorrhoid suppositories, drug injections, sclerotherapy and other methods.
