Black Vomit is mostly bleeding from the upper gastrointestinal tract or upper GI which includes the following:

Why does Vomit appear Black:

Just now we discussed the sources of Black vomit. But, do you know why the bleeding from gastrointestinal tract appears like Black vomit. Let us understand that first. It is because the upper GI bleeding from any source passes through the stomach.

During this phase, the enzymes of the stomach act on the blood and turn it into Coffee ground color or Black color. This is the reason we see Black vomit when we have Upper GI bleeding.

Black vomit Causes:

In most of the cases, patients don’t describe the vomit precisely as Black vomit, but they describe the vomiting or vomit to be brown, red or coffee ground vomit. Let us discuss the causes of such kind of Black vomit below:

Peptic ulcers can develop over the stomach lining or duodenal lining. Ulcers are the erosion in the mucosal lining of the organ. Peptic ulcers are erosion in the stomach or duodenal lining.
