What is Appendicitis?

Appendicitis is inflammation of the appendix

Appendicitis is a condition in which the appendix is inflamed and filled with pus. The appendix is a 2- to 3-inch, pouch-like sac that projects from the large intestine, also known as the colon, situated on the lower right side of the abdomen.

Appendicitis can be chronic or acute. Chronic appendicitis is a rare condition that causes mild symptoms for weeks, months, or even years. Acute appendicitis is a severe and sudden condition in which symptoms develop quickly over the course of 24 hours.
