What Could Trigger Black Vomit? 13 Possible Causes

Stomach Cancer 

A tumor inside the stomach can be a significant cause of internal bleeding. Cancer worsens after every meal, like the ulcer, since the stomach acids damage it and the surrounding tissue. Fortunately, it is not very common, but people still have to consider it depending on the circumstances. 

The other symptoms hinting it is cancer are abdominal pain, bloating, increased fatigue, and unexplained weight loss. Stomach cancer can also make a person feel full despite only eating a small amount because of the presence of the tumor. 

Stomach cancer tumors are found in the main body of the stomach or near the junction of the stomach and esophagus. The location is crucial since it can significantly affect the treatment plan for the tumor. It is a good sign if the cancer is caught early since immediate treatment allows for increased chances of survival. On the other hand, coffee ground vomitus is a bad sign since that can mean that the cancer is in its advanced stage.
