The most common symptoms of upper gastrointestinal bleeding mainly include: vomiting blood, black stools, or symptoms such as dizziness, palpitations, and fatigue, and even hypovolemic shock and hypovolemic anemia, etc. Therefore, when gastrointestinal bleeding occurs, if the patient has a large amount of bleeding and the bleeding is rapid, it is necessary to seek medical attention promptly, to administer fluid replenishment, volume expansion, and blood transfusion to replenish blood volume, along with symptomatic treatment such as medication and endoscopic hemostasis. If conservative treatment is ineffective, surgical treatment may be considered to avoid life-threatening risks.
