Patient discussion about appendix
Q. What Causes Acute Appendicitis? I've heard that appendicitis is a very common situation. What causes it to happen? Is there a way to avoid it?
A. Appendicitis is caused by an infection of the appendix, usually from bacterias that are already located in the abdomen. It is not a situation that can be avoided and can occur in a high prevalence in the population.
