Causes of Bleeding in the Digestive Tract

Causes of Bleeding in the Digestive Tract

Topic Overview

Causes of bleeding in the stomach and intestines (digestive tract) include:

  • Regular use of nonsteroidal anti-inflammatory drugs (NSAIDs) such as aspirin and ibuprofen. These medicines can irritate the stomach lining and cause an ulcer .
  • Inflammatory bowel disease .
  • Colon polyps or colorectal cancer , especially in older adults. It is important to identify and treat these as early as possible, because they may be life-threatening.
  • Frequently occurring hemorrhoids . People with hemorrhoids often do not seek treatment right away, resulting in chronic bleeding.
  • Esophagitis , which is irritation or inflammation of the esophagus (the tube that connects the throat to the stomach).
  • Hookworm and other parasites . These parasites feed upon blood from the intestinal wall . Significant blood loss can result if they are left untreated.
  • Long-distance running (runner's anemia ). People who regularly run long distances often have some type of bleeding in the digestive tract.
