A member asked:

Black stool that is brown on inside. could this be from too much grape juice and oreos? how long should it take for stools to go back to normal color?

Dr. Betsy Greenleaf answered

Specializes in Gynecology

Watch: Stool can be colored based on foods we eat and food coloring, however black stool can be concerning in that it can be a sign of bleeding in the intestinal tract. If continues or associated with abdominal pain, lightheadedness, shortness of breath or any other unusual symptoms then see a doctor or ER as soon as possible
