Digestive Diseases: Appendicitis
Appendicitis is an inflammation of the appendix, a 3 1/2-inch-long tube of tissue that extends from the large intestine. The appendix contains specialized tissue that can produce antibodies, but no one is absolutely certain what its function is. One thing we do know: We can live without it, without apparent consequences.
Appendicitis is a medical emergency that requires prompt surgery to remove the appendix. Left untreated, an inflamed appendix will eventually burst, or perforate, spilling infectious materials into the abdominal cavity. This can lead to peritonitis, a serious inflammation of the abdominal cavity's lining (the peritoneum) that can be fatal unless it is treated quickly with strong antibiotics.
Sometimes a pus-filled abscess (infection that is walled off from the rest of the body) forms outside the inflamed appendix. Scar tissue then "walls off" the appendix from the rest of the abdomen, preventing infection from spreading. An abscessed appendix is a less urgent situation, but unfortunately, it can't be identified without surgery. For this reason, all cases of appendicitis are treated as emergencies requiring surgery.
In the U.S., 1 in 15 people will get appendicitis. Although it can strike at any age, appendicitis is rare under age 2 and most common between ages 15 and 30.
Appendicitis occurs when the appendix becomes blocked, often by stool, a foreign body, or cancer. Blockage may also occur from infection, since the appendix swells in response to any infection in the body.
The classic symptoms of appendicitis include:
Dull pain near the navel or the upper abdomen that becomes sharp as it moves to the lower right abdomen. This is usually the first sign.
Almost half the time, other symptoms appear, including:

Diagnosing appendicitis can be tricky. Appendicitis symptoms are frequently vague or extremely similar to other ailments, including gallbladder problems, bladder or urinary tract infection, Crohn's disease, gastritis, intestinal infection, and ovary problems.
