 Peptic ulcers caused neither by Helicobacter pylori infection nor by nonsteroidal anti-inflammatory drugs are termed as IPU(idiopathic peptic ulcers)and show a 12% prevalence rate among Japanese patients with peptic ulcers. Based on the research after the 2011 Great East Japan earthquake, psychological stress during large-scale disasters is newly recognized as an independent risk factor for peptic ulcers.

 When not experiencing a disaster, IPUs are ordinary clinical situations, possibly having the following features:1)underlying comorbid arteriosclerosis, particularly in the antrum of the stomach, often showing refractoriness and 2)a high recurrence rate. Differences between H. pylori-unrelated IPUs and IPUs after eradication therapy of H. pylori are still unclear, and additional large-scale studies are needed for clarification.
