Unpublished data from the Hospital In-patient Enquiry in England, Wales, and Scotland between 1958 and 1972 show that the frequency of admissions to hospital for peptic ulcer, particularly gastric ulcer, has fallen. This seems more likely to have been due to a true fall in the incidence of ulcer than to changes in treatment. Some three times as many people are admitted to hospital with duodenal ulcer in the north as in the south, but the frequency of admissions for gastric ulcer seems to vary little. The reasons for these differences are not understood.
1958年至1972年间，来自英格兰、威尔士和苏格兰医院住院病人查询系统的未发表数据显示，因消化性溃疡（尤其是胃溃疡）住院的频率有所下降。这似乎更可能是由于溃疡发病率的真正下降，而非治疗方法的改变。北方因十二指肠溃疡住院的人数大约是南方的三倍，但胃溃疡的住院频率似乎变化不大。这些差异的原因尚不清楚。
