Anemia symptoms are often missed - discover key warning signs & subtle indicators many people overlook
Black, tarry stool can occur when there is bleeding into the esophagus, stomach, or intestines. In some cases, bleeding from the rectum can also cause this symptom. Bleeding is one of the most common causes of anemia. Therefore, a change in the color or appearance of the stools could be an indicator of a serious health problem that is also causing anemia. A change in bowel habits is a significant sign that a person should not ignore. In extreme cases, stomach or colon cancer can cause this symptom.
