6. Stomach Cancer and Black Poop
Stomach cancer is another possible cause of black stools since the disease may cause bleeding in the stomach. As in the case of esophageal cancer, anemia may develop due to the bleeding.
A person with stomach cancer may also notice bowel changes, such as diarrhea or constipation, narrow stool and changes in frequency of bowel movements. Other symptoms may include nausea and vomiting, diminished appetite and weight loss, fatigue, and abdominal pain and bloating.1Michael F.
