Marjorie Nolan Cohn, Nutrition & Dietetics, answered on behalf of Academy of Nutrition and DieteticsRed stool can come from red food coloring (such as candies, or drinks) or naturally red foods (like beets). It can also reult from bleeding hemorrhoids, or more serious lower GI conditions.
Robynne Chutkan, MD, Gastroenterology, answeredRed stool is most worrisome as it indicates bleeding in the lower gastrointestinal (GI) tract from conditions like hemorrhoids or diverticulosis, or more serious conditions like rectal cancer. Red stool can also be caused by ingesting red food coloring or beets. While it should always be reported, it's not always an ominous sign.
