7. Mallory-Weiss Tear and Black Poop
Black or tarlike stools may indicate the presence of a Mallory-Weiss tear, torn tissue in the lower esophagus. Violent and protracted coughing or vomiting often causes this condition, but it's also associated with alcoholism, hiatus hernia, trauma to the chest, chemotherapy and inflammation of the stomach or esophageal lining.
If severe blood loss occurs, the person may experience shock and collapse. Often, the bleeding stops on its own, but if it doesn't, treatments involve cauterization, blood transfusions and administration of the vasopressive drug, pitressin.12‘Mallory Weiss Syndrome.’ NORD (National Organization for Rare Disorders), rarediseases.org/rare-diseases/mallory-weiss-syndrome/.
