Overview

Appendicitis is mainly caused by the retention and obstruction of fecal matter, parasitic or bacterial infections of the appendix, and by physical damage to the appendix.

Causes

Common Causes

Common causes of appendicitis include:

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^[1].
Low dietary fiber intake
- Several studies offer evidence that a low fiber intake is involved in the pathogenesis of appendicitis^[2]^[3]^[4].
- 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^[5].
Appendicolith
Ascariasis
Bacteroides
Taenia infection
