Stools may appear black after eating too many cherries. Cherries contain a lot of natural coloring and iron, and eating a lot of cherries in a short period of time may lead to abnormal digestion and absorption in the intestines, and it will make the stools black. At this time, patients can improve the symptom by improving their diet and eating fewer or no cherries. If cherries are dark and black, it may also indicate that the pigment content in them is high, and eating too many of them will lead to the color of the stool due to the difficulty of being completely absorbed in a short period of time. There is no need to worry too much in this case, and this symptom can be made to ease after reducing the intake. If after stopping eating cherries there are still black stools, but also acid reflux, belching, vomiting blood and other symptoms, you need to go to the hospital to check whether there are gastric ulcers, duodenal bulbous ulcers and other diseases, to clarify the specific cause of the treatment under the guidance of the doctor.
