Appendicitis is swelling (inflammation) of the appendix. The appendix is a small pouch attached to the beginning of your large intestine.
Appendicitis is one of the most common causes of emergency abdominal surgery in the United States. It usually occurs when the appendix becomes blocked by feces, a foreign object, or rarely, a tumor.
