After anemia occurs due to upper gastrointestinal bleeding, it is necessary to rest more because if patients continue to move outdoors after developing anemia, it can lead to dizziness and, in severe cases, the possibility of fainting, which can endanger the patient’s life. Therefore, patients with upper gastrointestinal bleeding should pay more attention to rest and should appropriately have family members accompany them, as this is safer. The main causes of upper gastrointestinal bleeding may include peptic ulcers, acute erosive gastritis with bleeding, etc. Once upper gastrointestinal bleeding occurs, it is necessary to immediately visit the gastroenterology department of a formal hospital for a thorough examination with an electronic gastroscope to confirm the diagnosis.
