Black stool: When the stool is described as black that implies bleeding in the upper GI tract (stomach,esophagus). It is often described as looking like "coffee grounds". A simple test for iron in the stool is called the Hemocult. You like to drink the fruit of the vine which predisposes to GI bleeding.
