“The entire digestive tract helps with our immune system, but some scientists and doctors think the appendix may be a place for our body to store certain healthy types of gut bacteria that otherwise could be altered or changed during an intestinal illness or with overuse of antibiotics.

Appendicitis is an inflammation of the appendix. The appendix is a finger-shaped pouch that sticks out from the colon on the lower right side of the belly, also called the abdomen.

Appendicitis causes pain in the lower right part of the belly. However, in most people, pain begins around the belly button and then moves. As inflammation worsens, appendicitis pain typically increases and eventually becomes serious.

Although anyone can develop appendicitis, most often it happens in people between the ages of 10 and 30. Treatment of appendicitis is usually antibiotics and, in most instances, surgery to remove the appendix.”
