Your upper gastrointestinal (GI) tract includes your esophagus, stomach, and upper small intestine (duodenum).
Signs of bleeding from your upper GI tract may include vomiting or coughing up blood or coffee-ground like material. Or you may have black or tarry stools. Very small amounts of GI bleeding may not be visible and can only be found by a stool test. Sudden bleeding may result in low blood pressure, fast heart rate, or fainting.
Causes of upper GI bleeding can include:
- Tear in the lining of the esophagus
- Enlarged veins in the esophagus or stomach, especially in someone with cirrhosis
- An ulcer in the stomach or upper part of the small intestine
- Severe irritation of the stomach
- Inflammation of the digestive tract
- Abnormal growth (tumor) of the upper digestive tract
A bloody nose or mouth or dental problems may cause you to swallow blood. You may vomit this blood up. This is not true GI bleeding. Iron supplements and medicines for diarrhea and upset stomach can cause black stools. This is not GI bleeding and is not a cause for concern.
