Raisins cannot stop bleeding. Raisins are a nutritious food that does not stop bleeding and should not be used as a medication to treat blood in the stool. When you have blood in your stool, you should actively look for the cause of the disease and treat it according to the cause of the disease. Blood in stool is mostly caused by lower gastrointestinal diseases, and common causes include rectal and anal diseases (such as hemorrhoids, anal fissure), colorectal tumors, etc. If it is clear that the blood in stool is caused by rectal diseases, the cause of blood in stool is the rectum. If it is clear that the blood in stool is caused by rectal-anal diseases and the symptoms are more serious, surgical treatment should be considered (e.g. hemorrhoidectomy, anal fissure resection, etc.). If the symptoms are mild, the blood in stool can be treated by changing lifestyle habits, eating more vegetables and fruits and other fiber-rich foods to keep the stool clear. If the blood in stool is caused by colorectal tumor, usually the bleeding is due to the rupture of the tumor in the intestinal lumen and bleeding, those with less bleeding can continue to observe, those with more bleeding can consider taking oral hemostatic drugs (e.g. Yunnan Baiyao, etc.) and early surgical treatment. Those who have symptoms of blood in stool should seek medical treatment in time, after clear diagnosis and active treatment, in order to avoid delaying the condition.
