Which is a classic symptom of a peptic ulcer?

Burning stomach pain is recognized as a classic symptom of a peptic ulcer, particularly when it is related to the presence of acid in the stomach. This type of pain often occurs between meals or during the night, when the stomach is empty, and it may improve with the intake of food or antacids, only to return again.

Peptic ulcers can result from various factors, including infection with Helicobacter pylori, chronic use of nonsteroidal anti-inflammatory drugs (NSAIDs), or excessive acid production. The burning sensation is attributed to the erosion of the protective mucosal lining of the stomach or duodenum, leading to irritation and inflammation.

In contrast, an increased appetite is not typically associated with peptic ulcers; instead, patients may experience a decreased desire to eat due to pain. Sharp chest pain may indicate other conditions, such as myocardial infarction or gastrointestinal issues like esophageal spasm, rather than peptic ulcers. Nausea after eating can occur in various gastrointestinal disorders but is not a defining feature of peptic ulcers.
