Gastric ulcers are a common disease in gastroenterology, especially prevalent among outpatient clients. The symptoms of gastric ulcers vary widely, and some patients may not show any symptoms, only presenting with a decrease in appetite, which can lead to nausea and vomiting. Common symptoms of gastric ulcers include nausea, vomiting, abdominal distension, abdominal pain, and even a decrease in appetite. The abdominal pain is typically felt in the upper abdomen, can worsen after eating, and may resolve on its own without fever. However, if a gastric ulcer is accompanied by bloody stools, especially black stools or even vomiting blood, it is recommended that the patient seek further treatment at a local hospital. Therefore, for patients with gastric ulcers who experience symptoms such as nausea, vomiting, and abdominal pain, it is suggested to provide protective gastric treatment, typically lasting four to eight weeks.
