Appendicitis and Stress: What's the Connection?

No, appendicitis is not caused by stress. Appendicitis is inflammation of the appendix, which is a small, finger-shaped organ that projects from the large intestine. The cause of appendicitis is not known, but it is thought to be related to a blockage in the appendix, such as from stool, bacteria, or a foreign object. Stress can cause physical symptoms, such as headaches, nausea, and abdominal pain, but it does not cause appendicitis.
