Causes of Appendicitis

Scientists believe that this condition is caused by an obstruction in the appendix. The obstruction may be either partial or complete. The obstruction can be caused by enlarged lymphoid follicles, worms, trauma and tumors.  When there is obstruction in the appendix, the bacteria tends to multiply inside the organ leading to the formation of pus.  The increased pressure may cause pain or compress the local blood vessels.  Reduced blood flow to the appendix may form gangrene.  When the appendix ruptures, the fecal matter can fill the abdomen. The ruptured appendix may cause peritonitis which is the inflammation of the tissues that lines the abdominal wall. Other organs such as cecum, bladder and sigmoid colon can also become inflamed after a rupture.
