it's an important complicated issue becase:
GI bleeding + using Fe supplements are common together & both cause melena
and also sometimes GI bleeding is because of peptic ulcer in which treatment with bithmus is a stanard intervention so dual effect to cause dark stool

So.. doctors should keep this in mind because e.g. a doctor may think that bleeding hasn't stopped yet because of melena and proceed to more invasive diagnostic and theraputic procedures forgetting the side effects of the drugs........

but I'm still asking
