Gastric ulcers can cause damage to the gastric mucosa, and if the ulcer further affects the blood vessels, it can lead to rupture of the vessels and cause bleeding. Therefore, gastric ulcers should be treated actively. If the amount of bleeding is substantial, it is advisable to opt for endoscopic hemostasis or use hemostatic medications, while also treating the ulcer fundamentally. If the ulcer is large, a major part of the stomach may be removed surgically. Post-operative care is crucial, including maintaining a balanced diet; the diet should consist mainly of soft, easily digestible foods, with an emphasis on consuming more vegetables and fruits, and avoiding spicy and cold foods.
