Peptic ulcers are a common disease and often seen in clinical practice. They are typically manifested by discomfort in the upper abdomen, which may include abdominal pain, bloating, nausea, vomiting, and belching, and patients usually visit the gastroenterology department. The abdominal pain related to peptic ulcers, particularly the most typical and common symptoms, usually presents as pain above the navel, with chronic and recurrent attacks. It often relates to dietary habits, such as postprandial worsening in the case of gastric ulcers, whereas duodenal ulcers typically improve after eating and may involve hunger pain and night pain. Therefore, if patients exhibit these typical symptoms, it is recommended to perform a gastroscopy to ascertain the presence of duodenal or gastric ulcers. Complications can occur with peptic ulcers, with the most common being gastrointestinal bleeding, manifested by vomiting blood or bloody stools, with the latter appearing as tarry, watery stools. Thus, if patients present with typical symptoms of abdominal pain, bloating, and particularly bleeding or vomiting blood and bloody stools, peptic ulcers are the most likely cause. It is advised for patients to actively seek treatment at local hospitals and receive medication therapy.
