What causes blood in the morning?

Hemorrhoids include internal hemorrhoids, external hemorrhoids and mixed hemorrhoids. If the condition is not serious, combined with anal medication can effectively improve. If the amount of bleeding is more, the color is bright red, covering the surface of the stool, there may be anal fissure, severe cases need surgery. On the other hand, if the stool color is black, it may be caused by upper gastrointestinal bleeding, which needs to be checked by gastroscope and Helicobacter pylori. Serious cases need to be examined by enteroscopy to understand intestinal lesions, especially those who consider intestinal polyps or even intestinal cancer.
