The annual number of hospital discharges for peptic ulcer decreased in Finland from 1969 to 1974, mainly because of a smaller number of men with uncomplicated peptic ulcer disease. After the mid-1970s the number of hospital admissions remained stable, whereas the number of elderly patients increased. From 1979 to 1984 the number of hospitalizations for perforated ulcers remained stable, whereas those for ulcer haemorrhages increased, the increase being most marked in the older age groups. The age-specific mortality from peptic ulcer remained stable from 1969 to 1984 and rose thereafter among old patients. The risk of death from peptic ulcer was about 10-fold higher in patients over 75 years old than in younger age groups, and about half of the deaths caused by peptic ulcer occurred in patients over 75 years old. The men to women ratio among hospitalized patients decreased from 3.5 in the late 1960s to 2.1 in the 1980s, and the gastric ulcer to duodenal ulcer ratio was about 1.1 throughout the observation period.
