In medicine, melena or melæna refers to the black "tarry" feces that are associated with upper gastrointestinal bleeding. The black color is caused by the hemoglobin in the blood being altered by digestive chemicals and intestinal bacteria.
Iron supplements may cause a grayish-black stool that should be distinguished from the black, tarlike stool that occurs from bleeding ulcer.
The most common cause of melena is peptic ulcer disease. Any other cause of bleeding from the upper gastrointestinal tract, or even the ascending colon, can also cause melena. Melena may also be a sign of drug overdose if a patient is taking anticoagulants, such as warfarin. It is also caused by tumors, especially malignant tumors affecting the esophagus, more commonly the stomach & less commonly the small intestine due to their bleeding surface. However,the most prominent and helpful sign in these cases of malignant tumors is haematemesis. It may also accompany hemorrhagic blood diseases (e.g. purpura & hemophilia). Other medical causes of melena include bleeding ulcers, gastritis, esophageal varices, Meckel's diverticulum and Mallory-Weiss syndrome.
Once I bought a curious bottle,
Once I bought a bottle for fun.
Tell me what you gonna do with the bottle
When the curiousity's done.
Well I brought it out to the Bo Bo's party
Then I got it in to the company,
Then I brought it up to the boys in the backroom,
They got the knack to tune in on me,
Then I brought it up to the boys in the backyard.
I find it hard to hold on me,
I find it hard to hold, I find it hard to hold,
I find it hard to hold on me, I find it hard to hold on me,
I find it hard to hold, hard to hold, hard to hold.
You know, I've been bad, but
I would be good instead.
Ah, if my man did half of the things that he said,
I wouldn't have to go to the Bo Bo's party
I wouldn't have to go to the company,
I wouldn't have to go to the boys in the backroom,
With their knack to tune in on me,
I wouldn't have to go to the boys in the backyard.
I find it hard to hold on me,
I find it hard to hold, I find it hard to hold,
I find it hard to hold on me, I find it hard to hold on me,
I find it hard to hold, hard to hold, hard to hold.
You know, I've been bad, but
I would be good instead.
Ah, if my man did half of the things that he said,
I wouldn't have to go to the Bo Bo's party
I wouldn't have to go to the company,

I wouldn't have to go to the boys in the backyard.
I find it hard to hold on me,
I find it hard to hold on me,
I find it hard to hold.
