The occurrence and development of acute ulcers in Sofia during the period of heavy economical recession--January trough February 1991--is analyzed. There is a clear cut increase in the total number and rate of acute duodenal ulcers from 2 to 14%. No gastric ulcer cases are recorded. The young age group--up to 40 years of age--is mainly affected (79% of cases). The incidence among the female population shows a noticeable rise.
