The Sailor’s Stomach

Abstract

AbstractThe incidence of peptic ulceration in the Royal Navy is higher than in a comparable civilian population and has been rising. It is highest in sedentary groups and lowest in active groups in which physical activity and job satisfaction appear to be important. Four factors appear directly responsible for the high incidence of peptic ulceration in sailors: the personality of those attracted to a seagoing life; operational conditions associated with tension, responsibility and manpower shortages; inadequate physical activity; a diet rich in refined carbohydrates. Contributory factors are smoking, alcohol, noise, domestic unhappiness and intestinal parasites. Job satisfaction and physical fitness appear to reduce the risk. A link appears to exist between peptic ulceration and urolithiasis in the Royal Navy. Gastric secretory studies have failed to provide meaningful information and high acid levels have been found in groups with the lowest incidence of peptic ulceration. Changes in catering arrangements, diet and conditions of service are unlikely to reduce the incidence of peptic ulceration.
