Understanding Gastritis: Causes, Symptoms, and Treatment options

6. Abnormal Stool

Sometimes, people with gastritis also observe abnormalities in their stool. Feces may be black, gritty, and tar-like, which can be an indication of bleeding in the upper digestive tract. In rare cases, perceivable blood may also be present. Bloody stools suggest stomach ulcers, which are complications of gastritis. People who experience changes in stool that do not correct quickly should schedule an appointment with a doctor.
