Bleeding in stool can be divided into two kinds of bleeding according to the color: one kind of bleeding with bright red color, usually around the anus, which may be bleeding from internal hemorrhoids, bleeding from anal fissure, or bleeding from rectal polyps, among which internal hemorrhoids are the most likely to bleed. The bleeding of internal hemorrhoids is not heavy at the beginning, but with the gradual severity of internal hemorrhoids, jet-like bleeding may occur. If the bleeding is prolonged, it may lead to anemia of the organism, which will be troublesome to deal with at that time. So if internal hemorrhoid bleeding is treated early, you can choose conservative treatment with internal hemorrhoid suppositories, or you can choose surgical treatment. Bleeding from anal fissures and rectal polyps is usually small and does not cause particularly serious symptoms. Another type of bleeding is dark red bleeding, which is usually bleeding from the upper part of the colon or upper gastrointestinal tract, and needs to be specifically diagnosed by e-colonoscopy and e-gastroscopy.
