Overview

Common causes of appendicitis include obstructive fecaliths, parasitic or bacterial infections of the appendix, trauma, and lymphadenitis.

Causes

Common Causes

Common causes of appendicitis include:[1]

  • Foreign bodies
  • Trauma
  • Intestinal worms
  • Lymphadenitis
  • The occurrence of an obstructing fecalith
    • The occurrence of a fecalith in the appendix seems to be attributed to a right sided fecal retention reservoir in the colon and a prolonged fecal transit time.[2]
  • Low dietary fiber intake
    • Several studies offer evidence that a low fiber intake is involved in the pathogenesis of appendicitis.[3][4][5]
    • This link between low fiber intake and appendicitis is in accordance with the occurrence of a right sided fecal reservoir and that dietary fiber reduces fecal transit time.[6]
  • Appendicolith
  • Ascariasis
  • Bacteroides
  • Taenia infection
