The very high prevalence of haemorrhoids in the most economically developed countries is contrasted with their low prevalence in rural communities in developing countries. Traditional concepts of causation are shown to be no longer tenable. It is argued from epidemiological, clinical and experimental evidence that the fundamental cause of piles is straining at viscid stools which are the result of fibre-depleted diets.
在经济最发达的国家,痔疮的患病率非常高,而在发展中国家的农村地区,其患病率却很低。传统的病因观念已被证明不再站得住脚。从流行病学、临床和实验证据来看,有人认为痔疮的根本原因是排出黏稠粪便时用力,而这种黏稠粪便源于膳食纤维缺乏的饮食。
