Pathophysiology of Hemorrhoidal Disease

  • Paul A. Lucha

Background

The prevalence of hemorrhoidal disease is difficult to determine. Some estimate that up to 90% of patients may complain of hemorrhoidal symptoms at least once in their lifetime [1]. The incidence of hemorrhoids increases with age, with males affected twice as often as females. Age predisposes to a laxity of Treitz’s ligaments, with an average onset after age 30. There are hereditary predispositions; however, occupational predisposition has not been demonstrated. Low residue diets seen typically in industrialized countries have been described as contributing to symptomatic hemorrhoids, presumably by causing smaller hard stools. This is clearly not the only etiology however, as those patients with diarrhea may also develop symptomatic hemorrhoids. Diets high in fiber may reduce the risk of hemorrhoid congestion. Although increased intra-abdominal pressure such as that seen in chronic pulmonary disease, prostatism, and pelvic tumors has been postulated to contribute to...
