Core Tip
Core tip: We determined the characteristics of hemorrhagic gastric/duodenal ulcers in the post-earthquake period within one medical district. We divided hemorrhagic gastric/duodenal ulcers into two groups, the acute stress phase group, consisting of the first month after the earthquake disaster, and the chronic stress phase group, from the second through the sixth month. We concluded that severe stress caused by this earthquake disaster exacerbated the characteristics of hemorrhagic gastric/duodenal ulcers.
