Appendicitis is swelling (inflammation) of the appendix. The appendix is a small pouch attached to the beginning of your large intestine.
Causes, incidence, and risk factors:
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.
The symptoms of appendicitis can vary. It can be hard to diagnose appendicitis in young children, the elderly, and women of childbearing age.
