Organic and psychosocial risk factors for duodenal ulcer.J Psychosom Res 1995; 39(5):531-48JP
Duodenal ulcer (DU) is a common medical disorder which frequently becomes chronic. The factors involved in the aetiology of DU are poorly understood. Evidence for the contribution of psychosocial factors to the onset of DU is reviewed in the context of evidence of organic factors, genetic and environmental, with special reference to new evidence of infectious agents in the aetiology of DU. Recent progress in understanding of biological forces of duodenal ulcer disease has lead to a substantially revised view of psychosomatic factors. Although these may be of significance, their relative contribution to aetiology is likely to be modest.
