Abstract
Admissions to 166 American Veterans Administration Hospitals for duodenal ulcer, bleeding duodenal ulcer, perforated duodenal ulcer, essential hypertension (control diagnosis), and all diseases were counted as to calendar month of occurrence over a 6-year period. Duodenal ulcer admissions were less frequent in June, July, and August. Perforated duodenal ulcer was, in addition, less frequent in January. These deficits contrasted sharply with admissions for control categories. Summer deficits are more characteristic of duodenal ulcer than spring and fall peaks. Regional data in this study did not support the possibility that the summer deficit is related to hot weather. Perforations vary with time under more influences than nonperforated duodenal ulcer.
