The majority of internal hemorrhoid bleeding is bright red, but if there is a significant amount of bleeding, blood may accumulate within the anal canal and form clots, resulting in darker colored blood in the stool. To identify and diagnose whether it is bleeding from internal hemorrhoids, it is recommended that patients undergo an anoscopic examination. If obvious bleeding points are found near the mucosa around the dentate line, it is mostly due to internal hemorrhoids. To treat bleeding from internal hemorrhoids, it is first necessary to take oral or topical hemostatic medications for symptomatic treatment. If the internal hemorrhoid bleeding has been prolonged, or in cases of chronic blood loss, further surgical ligation may be necessary to stop the bleeding and prevent anemia due to excessive blood loss. (The use of medications should be under the guidance of a doctor.)
