What are the symptoms of mild gastric bleeding after drinking alcohol?

The main symptoms of mild gastric bleeding after alcohol consumption include: 1. Nausea and vomiting: Alcohol irritation of the gastric mucosa may cause nausea and vomiting, with possible blood traces in the vomit. 2. Upper abdominal pain: Alcohol irritation of the gastric wall nerves can cause local spasms and inflammatory reactions, leading to upper abdominal pain, usually located near the lower end of the sternum. 3. Black stool: Bleeding caused by gastric mucosal damage is oxidized in the intestine and expelled with feces, resulting in black stool, which typically indicates a significant amount of gastrointestinal bleeding. These symptoms may appear individually or simultaneously. If symptoms of gastric bleeding after alcohol consumption occur, prompt medical attention is recommended to assess the condition of the stomach and receive appropriate treatment.
