Question 3

is it possible for one 30 ml of peptobismol to be enough to cause black stool for two days?

Accepted Answer

Yes: Peptobismal is capable of causing black stools. Pepto-bismol contains a little bit of bismuth and when the bismuth combines with the sulfur in your saliva and intestinal tract it makes a black colored substance which is called bismuth sulfide.

Accepted Answer

Black stools: Black stools are seen with bleeding from the upper gi tract-usually stomach or duodenum. Blackish stool can be caused by taking iron supplements or bismuth products like peptobismol. A simple test in the physicians office can detect whether the black stool is from blood or not. I recommend seeing your MD ASAP and getting that simple test done. Gi bleeding is a serious issue.

Question 8

i had a black stool yesterday and i knew because i ate black licorice and iron pill. so i stopped eating it but until now i still have a black stool ?

Accepted Answer

Not normal, get help: Blood in stool is a warning sign. Brisk bleeding warrants emergency care. Causes of bleeding may be predictable (e.g. rectal trauma), but evaluation is always appropriate. A rule of thumb (but not absolute): black stool means bleeding comes from upper GI tract; grape jelly stool from small bowel; silver stool from biliary tree; burgundy stool from right colon; red blood from left colon to anus.
