Whether a stomach ulcer requires hospitalization depends on the condition. For minor ulcers, if the pain is mild and there are no significant symptoms of vomiting or nausea, treatment can be managed with medication, such as drugs that inhibit stomach acid secretion and protect the gastric mucosa. It is also important to regulate diet, eat soft foods, avoid cold, spicy foods, and alcohol, as symptoms can gradually ease. If the ulcer is larger and exhibits perforation or bleeding, hospital treatment is necessary, usually involving a significant portion of the stomach being surgically removed to completely cure the ulcer. (Medication should be taken under the guidance of a doctor.)
