Upper gastrointestinal bleeding is relatively common in clinical practice. Its main causes include bleeding from gastroduodenal ulcers, rupture of esophagogastric varices, and bleeding caused by gastric cancer, among others. When upper gastrointestinal bleeding occurs, it is crucial to seek medical attention promptly. After systematic treatment, if the symptoms of bleeding are controlled, the patient can then consume small amounts of clear broth and thin porridge, and gradually transition back to a normal diet. However, the patient should avoid spicy and irritating foods to prevent the recurrence of gastrointestinal bleeding.
