Discovering hidden functions of the appendix and its impact on body health

The appendix was long considered useless, but recent studies have shown that it plays a vital role in maintaining gut health and strengthening the immune system.

The appendix is ​​a small, worm-like protrusion located at the junction of the small and large intestines, measuring about 7–10 cm in length, and is well known because of its inflammation, which requires emergency surgery.

Recent studies have shown that the appendix acts as a reservoir for beneficial bacteria that make up the gut microbiome. When infections occur or after taking antibiotics that may destroy these bacteria, the appendix helps restore the bacterial balance by transporting them back into the intestines.

The appendix also contains a large amount of lymphatic tissue, which protects the body from infection, plays an important role in the development of the immune system in early life stages, and helps in the production of antibodies.

Some scientists suggest that the appendix was essential for our ancestors to digest foods rich in plant fiber. While this function has become less important in modern humans, the appendix has adapted to perform other useful functions.

Of course, many people can live without an appendix, as the body can compensate for its absence. However, studies have indicated that people who have had their appendix removed may sometimes experience an imbalance of gut bacteria or recurrent intestinal infections due to the loss of their supply of beneficial bacteria.

Appendicitis occurs when the opening of the appendix becomes blocked by food debris, parasites, or bacterial overgrowth, leading to bacterial multiplication and inflammation of the appendix, and in some cases, to its rupture, requiring urgent surgery.

In general, the appendix can be considered further evidence that the human body does not contain anything “extra” without a function.
