Symptoms Of Mallory-Weiss Syndrome

Black Or Bloody Stools

Black or bloody stool is another common symptom, and in many cases, the stools can be melenic, or as black as tar. If the patient is bleeding heavily, however, the blood in the stools will be red. Since heavy blood loss can be life-threatening, the patient should get emergency care if they find a lot of red blood in their stools.

Black stools, which are sometimes called melena, can indicate injuries in the gastrointestinal tract. The dark color can also be caused by eating foods with dark colors, like blueberries. Some medications, like iron supplements or medicines containing bismuth, can also cause stools to turn black. Bloody stools can become tar-like as they move down the digestive tract and the blood mixes with digestive acids.
