2. Gastric ulcer: It is a type of ulcer disease, and the main symptoms are recurrent upper abdominal pain, accompanied by acid reflux, belching, nausea, vomiting, or hematemesis. During a gastroscopy, round or oval ulcer lesions can be seen in the stomach. It is closely related to genetic factors, and may also be caused by mental factors, infection factors, and lifestyle factors.

3. Gastric tuberculosis: Some symptoms are relatively mild and may not even be discovered. Some people may have symptoms similar to those of gastritis, gastric ulcer, or gastric cancer, including abdominal pain, upper abdominal discomfort, vomiting, and nausea. It is contagious.

4. Gastric injury: Gastric injury may be caused by strong pathogenic factors, such as sharp instruments. Most patients will experience upper abdominal pain, accompanied by nausea and vomiting.
