Causes of Appendicitis

Appendicitis is caused by a blockage of the inside of the appendix (also known as the lumen).

 

What Causes the Blockage?

In most cases, feces will cause a blockage inside of the appendix. However, a bacterial or viral infection in the digestive tract can lead to swelling of the lymph nodes, which squeezes the appendix and causes obstruction. This is known as lymphoid hyperplasia. In rare cases, traumatic injury to the abdomen, or even genetics, may also cause blockage inside of the appendix.

 

Summary

A blockage of the inside of the appendix leads to increased pressure, impaired blood flow, and inflammation. Gangrene and rupture (breaking or tearing) of the appendix can result if the appendix blockage is not treated in a timely manner.
