Black colour in the stool might be due to
the presence of blood and is called
melena. During this condition, blood that
originates from the upper parts of the
digestive system such as the mouth,
throat, oesophagus, stomach and duodenum
can turns black when the blood comes into
contact with stomach acid. Bleeding from
some of the upper parts of the respiratory
system such as the nose can also cause
black stools if the blood is swallowed.
Conditions like peptic ulcers, stomach
cancer, nose bleeding, oesophageal
haemorrhoids can cause melena. To
diagnose the condition, you can request
laboratory tests to confirm the presence
of blood in the stools. This is the frist
step ... and you can consult and internal
medicine specialist for advice and
consultation.
