Patients with upper gastrointestinal bleeding who experience symptoms such as cold sweats, fainting, reduced urine output, dry mouth, etc., may be experiencing hemorrhagic shock and should promptly visit the gastroenterology department or emergency department of a formal hospital for timely emergency treatment. Measures include establishing an intravenous line and actively rehydrating to replenish lost fluids and blood volume. Additionally, if the patient's condition permits, it is crucial to perform a thorough gastroscopy to ascertain the cause and location of the bleeding. When necessary, endoscopic hemostasis can be carried out. Patients with upper gastrointestinal bleeding also need treatments such as acid suppression and protection of the gastric mucosa.
