What may bee the problem if I have black or dark stools?

Hello Anon

Thank you for writing.

There are many causes of black stool. Are you feeling any kind of digestive discomfort? If so, this black stool could be a symptom of GI distress - including bleeding from ulcers or other conditions.

Diet can also be a cause - dark foods, from black licorice, to blackberries to blueberries, these dark stools are simply a reflection of diet.

If you feel your diet is not the cause, it's a good idea to see advice from your doctor, to rule out any internal condition.
Best,
