Blood in the stool: Blood coming out of the anus, blood in the stool, or all blood in the stool, bright red, dark red or tarry in color, are all called blood in the stool. Blood in stool is usually seen in the lower gastrointestinal tract, especially in the colon and rectum, but occasionally in the upper gastrointestinal tract. The color of blood in the stool depends on the location of the bleeding, the amount of bleeding, and how long the blood stays in the intestine. Dry bleeding stools caused by hemorrhoids Dry bleeding stools are an important “indicator” of hemorrhoids, and once this symptom occurs, it is a reminder that “hemorrhoids are also a disease and should be checked and treated in the hospital”. The main reason for this is the fact that you can’t get the hemorrhoids to come back. As a result of the dryness of the stool, it is easy to squeeze the nucleus of the hemorrhoid and cause blood in the stool, and patients often try to tolerate the inconvenience, making the stool even drier, and so on, forming a vicious circle.
