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.
