Bleeding stools need to be determined by their color to determine if a colonoscopy is needed. If the color is bright red, the bleeding is usually near the anus. Doing anoscopy or proctoscopy, you can determine where the bleeding is, and then use medicines such as hemorrhoid cream and hemorrhoid suppositories to cool and stop the bleeding. If the medication does not work well, you can further just do an electronic colonoscopy, which is a colonoscopy, to check if there is any bleeding in the upper part of the intestinal segment. If the bleeding is dark red, you need to do e-colonoscopy directly, because the dark red blood is usually bleeding from the upper part of the intestine, and after digestion in the intestine, the blood becomes dark red in color. Nowadays, it is generally recommended that people over 50 years of age can have a colonoscopy once a year to prevent the detection of some intestinal diseases and facilitate treatment as soon as possible.
