Bleeding in the Digestive Tract

Bleeding in the digestive tract is a symptom of a problem rather than a disease itself. Most causes of bleeding are related to conditions that can be cured or controlled, such as hemorrhoids.

The cause of bleeding may not be serious, but locating the source of bleeding is critical. The digestive or gastrointestinal (GI) tract includes the esophagus, stomach, small intestine, colon, rectum, and anus. Bleeding can come from one or more of these areas -- from a small area such as an ulcer on the lining of the stomach or from a more diffuse problem such as inflammation of the colon.

Bleeding can sometimes occur without you even knowing about it. This type of bleeding is called occult or hidden. Fortunately, simple tests can detect occult blood in the stool.

What Causes Bleeding in the Digestive Tract?

Bleeding from the esophagus can be caused by:

  • Esophagitis and gastroesophageal reflux. Stomach acid that refluxes (returns) back into the esophagus from the stomach can cause an irritation and inflammation of the esophagus (esophagitis) that may lead to bleeding.
  • Varices. Abnormally enlarged veins usually located at the lower end of the esophagus or the upper stomach, called varices, may rupture and bleed massively. Cirrhosis of the liver is the most common cause of esophageal varices.
  • Mallory-Weiss tear. This is a tear in the lining of the esophagus that usually is caused by prolonged vomiting but may also result from other causes of increased abdominal pressure, such as coughing, hiccupping, or childbirth.

Bleeding from the stomach can be caused by:
