GI bleeding can result from a number of digestive disorders, including:

GI bleeding can be visible in the form of vomiting of blood, bright red bloody stools or black tarry stools (melena). Even a small amount of GI bleeding that isn't visible can result over time in a shortage of red blood cells in your blood (anemia).

Pinpointing the source of GI bleeding can be especially difficult if it starts in the small intestine. When the source can't be identified, the term obscure GI bleeding is used.
