Factors in the aetiology of chronic duodenal ulcer in Ibadan

The aetiological factors at work in Nigerians with duodenal ulcer were examined. Stress and dietary factors were found to be major agents in the precipitation of exacerbations and recurrences of symptoms. Of the dietary agents, chillies and cassava preparations in the form of 'eba' and 'gari' are potent ulcerogenic food substances. Aspirin, alcohol and smoking also contribute to the worsening of the conditions but are not major factors.
