What are the differential diagnoses of acute upper gastrointestinal bleeding

The differential diagnosis of acute upper gastrointestinal bleeding includes gastric ulcer bleeding, duodenal ulcer bleeding, gastric cancer bleeding, etc. The relevant explanations are as follows:

1. Gastric ulcer bleeding The

gastric ulcer of gastric ulcer patients develops continuously, which will rupture the gastric blood vessels and cause bleeding, often accompanied by symptoms of stomachache and dyspepsia.

2. Duodenal ulcer bleeding

Duodenal ulcer develops continuously, which will make local blood vessels fragile and broken, causing blood to gush out and causing hematemesis.

3. Gastric cancer bleeding After gastric

cancer occurs, cancer cells stimulate the stomach wall, causing damage to the stomach wall and promoting blood discharge, usually accompanied by fever, fatigue, weight loss and other symptoms.
