Red stool but not blood is considered to be caused by dietary factors. For example, red stools occur after consuming too much red food such as red dragon fruit, watermelon, red dates, tomatoes, red peppers, etc. This is a physiological phenomenon. Usually the color of the stool will return to normal after the food is completely excreted and no special treatment is needed. If diet is ruled out, consider whether the symptoms are caused by gastrointestinal dysfunction, you can take appropriate drugs to help digestion, as well as probiotics to regulate. For example, the stomach and food tablets, bifidobacteria, etc.. At the same time, pay attention to a light diet, eat less and more meals. Avoid drinking alcohol and spicy and stimulating food. If accompanied by abdominal pain and other symptoms, it is best to do a stool routine plus occult blood and occult blood test to rule out the possibility of bleeding.
