title: [Hemorrhoids: epidemiology and correlation with chronic constipation].
abstract: Following a review of international literature, AA report main results and refer their opinion about the correlation of hemorrhoidal disease with constipation, considering some variants as well as age, sex, breed, social-economic condition and geographic distribution in USA, England and Wales. Epidemiologically ten millions of people, in USA, are affected by hemorrhoidal disease; the incidence rate is 4.4% with an age distribution that shows a prevalence between 45-65 years old subject while constipation has an exponential increase with aging. Hemorrhoidal disease is significantly influenced by sex and geographic distribution that is in white breed more than in black, in social high class and in men more than women. In black breed constipation and hemorrhoidal disease present especially in lower social classes. Based on these results hemorrhoidal disease shows on epidemiological pattern that differ from constipation's one. Many questions are still present about correlations between hemorrhoidal disease and chronic constipation regarding etiopathogenesis. Only future case-control studies will solve the problem.
