The appendix is a small tube at one end of the large intestine. It is closed at one end, like a sort of pocket. It has to be removed when it becomes seriously inflamed by an infection, which is quite common. When the substances from the intestine enters the appendix and cannot easily get out again then these substances harden, forming a plug, which squeezes the appendix’s blood vessels. This may lead to stoppage of blood supply to the appendix, and may result into an infection. The symptom of infection is when the pain starts in the stomach, which is concentrated on the right side of the body. Then it’s time to call a doctor and have the appendix removed by a simple and quick operation.
