This is Dr. David
this could be very serious
tar black stool can be a sign of bleeding from the upper GI system like bleeding from the stomach or from the esophagus.
you need to go to the A&E department at the hospital right away
and get your stools checked for blood and blood test to check your red blood cell count and iron and ferritin levels.
if you have bleeding from your stomach or esophagus, you can loose a lot of blood in a week and this can land you in the hospital
black tar blood from your vagina for your periods can be a sign of old blood from the uterus coming out
you should go to the hospital right away from evaluation
you might need a GI doctor to go down into your esophagus and stomach with a thin camera scope to look for areas of bleeding to stop it.
