To determine whether upper gastrointestinal bleeding has stopped without doing tests: 1. it is to stop vomiting blood, or to stop vomiting coffee-like material, while the symptoms of stomach pain, bloating and acidity have been reduced. 2. secondly, there are no more black stools, which can be observed by themselves. But some minor bleeding, which is not easy to observe from the surface symptoms, should be examined: 1. do fecal occult blood test, negative for 3-5 days, proving that there is no more blood accumulation in the intestine. 2. do routine blood test, red blood cell count and hemoglobin count no longer continue to decline, proving that there is no more blood loss. 3. the most definite is to use gastroscopy to directly observe whether there is active bleeding in the gastroduodenum. In short, to determine whether the bleeding has stopped should be considered comprehensively, there are some bleeding and no obvious subjective feeling of gastrointestinal tract, it may be difficult to detect the disease without the help of instrumentation and equipment examination, so usually pay more attention to the diet diarrhea and physical examination.
