What Causes Acute Appendicitis?
• Appendicitis is usually caused by a bacterial infection, although the reason the appendix becomes infected is unknown.
• The appendix may become obstructed by a lump of feces, calcium salts and fecal debris (called fecaliths) or tumors (rarely), leading to inflammation and infection.
• Swelling and inflammation lead to infection, blood clot or rupture of the appendix.
• Lymphoid hyperplasia is associated with inflammatory and infectious disorders such as Crohn disease, measles, amebiasis, gastroenteritis, respiratory infections and mononucleosis.
