Causes of Appendicitis
The cause of appendicitis is inflammation of the appendix. It is thought that appendicitis begins when the output of the appendix to the colon is blocked. The obstruction may be due to an accumulation of thick mucus in the appendix or an infection.
The mucus or stool hardens, becoming strong, blocking the normal flow of mucus in the area. Another possibility is that the lymphatic tissue to swell and block the appendix. After the blockage, bacteria normally found in Appendix begin to infect the wall of the appendix.
The immune response system, will respond to the accumulation of bacteria in the appendix leading to inflammation and accumulation of cells in the area. Another possibility for deriving appendicitis is rupture of the appendix followed by bacterial infections out of the appendix. The causes of this breakdown are not clear, but may be related to changes that occur in lymphoid tissue.If the inflammation and infection spread through the wall of the appendix, the appendix can rupture. After rupture, infection can spread throughout the abdomen, however, usually limited to a small area surrounding the appendix.
Sometimes the body is able to contain the appendicitis without surgical treatment if the infection and inflammation have not spread throughout the abdomen. Inflammation, pain and symptoms may disappear. This is particularly true in elderly patients.
