Journal of the Islamic Medical Association of North America
We studied 1250 duodenal ulcer patients during an eight year period to see the role of constitutional and environmental factors in the etiology of duodenal ulcer disease. A/I the patients studied were endoscopically proven to have duodenal ulcer. In our area, duodenal ulcer was found 15 times more frequently than gastic ulcer. It was more common in males and the highest incidence was recorded between 20 and 40 years of age. The disease was unaffected by the seasons and no significant ethnic
... nificant ethnic variation was observed; however, the disease was associated with belonging to low income groups and unskilled professions. It was more common among rice eaters, those who were irregular in taking meals, and ii was common in nonvegetarians. Consumption of alcohol, tea or coffee was not associated with the disease, but the disease was more prevalent among smokers than nonsmokers. Pan chewing habit did not have any bearing on the disease pattern.
