A member asked:
Can gi bleed turn only half the stool black... when melena enters toilet water does it turn the water red or black...can melena be solid?
A doctor has provided 1 answer
Yea: Melena can be intermittent. It does not tend to change the color of the water. It can be associated with constipation known as (tarry stool). Diarrhea occurs usually if there is an active acute bleeding, which is usually bright red.
