Peptic ulcers include gastric ulcers, duodenal bulb ulcers, and so on. Gastrointestinal bleeding is one of the common complications of peptic ulcers, usually caused by the ulcer being relatively large or deep, invading the blood vessels, leading to vessel rupture and resulting in bleeding. For minor bleeding, the patient may not have any discomfort symptoms, primarily indicated by black stools or a positive fecal occult blood test. If there is substantial bleeding, it can lead to symptoms such as vomiting blood. Such cases need attention and usually require hospitalization for observation and treatment. Sometimes, recurrent gastrointestinal bleeding may require surgical treatment.
