Hi,I am Dr. Subhankar Chakraborty (Gastroenterologist). I will be looking into your question and guiding you through the process. Please write your question below.
Hi I had 20 black olives Tuesday night for dnner,...Is it possible that it would have taken until Thursday morning to see in the front edge of stool to be black (front 1/4 was black and back 3/4 was normal color) and the next bowel movement had only a couple specs of black mixed with brown?

Does Eating Olives Cause Black Stools?
Thank you very much for contacting healthcare magic. Excessive amounts of olive may cause black spoted stool. Lucorice or blueberries may cause black stool if it take more in amounts. Black stool sometime because of blood clot also. If this problem is still present than do stool examination test for diagnosis. Take care.. Thank you very much.
