Appendicitis is usually caused due to an obstruction or blockage of the appendix. This infects the appendix and causes inflammation, which results in painful appendicitis symptoms. A part of the gastrointestinal tract, the appendix is located on the lower right side of the abdomen. It is connected to the large intestine and is shaped like a tube or a pouch.

Appendicitis is caused due to the inflammation of the appendix. The appendix gets inflamed when it is clogged with mucus, fecal matter, parasites, or bacteria. Although the appendix does not perform any important function in the body, its presence in the gastrointestinal tract is considered essential for the health of the immune system.
