If there is no blood on the surface of the stool and there is blood when you wipe the anus with a piece of paper, it is possible that the stool has scratched the skin on the surface of the anal canal, which may cause bleeding. If you have a mild case of blood in the stool and the symptoms are not very serious, you can skip the treatment. Just pay attention to your diet and avoid spicy and stimulating foods as well as fried foods. Eat some light, easy to digest food, such as ribs porridge or lean meat porridge with vegetables, noodles and so on, which is easier to help the bowel movement. Increase the intake of fruits and vegetables and drink more water. If the stool is still dry and hard, you can also take pills such as Ma Ren Pills or Sophora Jiao Pills to moisten the bowels. If there is pain and discomfort in the anus, you can apply some ointment on the anus, such as anal tylenol ointment or ma yinglong hemorrhoid ointment, etc., which can play a role in clearing away heat and detoxification, cooling blood and stopping hemorrhage. Generally speaking, through dietary modification, coupled with anal medication, the symptoms of blood in the stool paper can be improved.
