[Characteristics of the course of gastroduodenal diseases in metallurgy workers].

Questionnaires were distributed among 1500 heat treatment metallurgic workers and 612 workers engaged in normal temperature working conditions. The former group had a markedly higher level of gastroduodenal damages. The risk-factors, apart from the behavioral ones, included working in shifts, irregular nutrition. The major diseases were gastroduodenitis with ulcerous clinical manifestations, and high-degree acid formation and consequent pathologic developments in the antral section of the stomach and the duodenal bulb.
