You should never ignore any indication that you have bleeding in your gastrointestinal system -- including the stomach -- no matter the cause. Symptoms of acute GI bleeding can signal a life-threatening situation and individuals should seek immediate medical attention. Also, those with symptoms of chronic GI bleeding should seek medical attention in order to find the source of their bleeding.
Causes of bleeding in the stomach can include:
- Ulcers:
Ulcers may enlarge and erode through a blood vessel, causing bleeding.
- Gastritis
- Cancer
- Gastric varices
- Dieulafoy lesions
- Portal gastropathy
