It is possible that eating cherry stools can turn red and black. Cherries are a common fruit, and if a large amount of cherries are consumed in a short period of time, cherries contain iron, which, under the fermentation of intestinal bacteria, will produce iron sulfide and form black color. Cherries themselves also contain red plant pigments, these substances are difficult to be completely digested if they enter the gastrointestinal tract in large quantities, and the substances that are not digested will form red-black feces and be discharged from the body. If after consuming cherries, the stool turns red and black in the short term, and then stops appearing after a few days, there is no need to worry, it is a normal phenomenon. If the stool turns red for a long time and still does not improve after you stop eating cherries, you need to consider whether there are bleeding hemorrhoids, gastrointestinal bleeding, etc., which cause the stool to turn red with occult blood or certain blood system diseases, and promptly check and find the cause for symptomatic treatment.
