Today's Exactly100: "Do Not Exercise after Eating or You'll Get Appendicitis" - Kasabihan

That warning is a classic—memorable, dramatic, and wrong. This myth persists because it’s a neat rule for parents: “Don’t play after eating.”

Appendicitis is usually a blockage—hardened stool, swollen tissue after an infection—followed by inflammation. What exercise can do is simple: on a full belly it can trigger cramps, reflux, nausea, or the famous side stitch. And if appendicitis has already started, motion can sharpen the pain, fooling everyone into thinking it caused it. So the “mechanism” implied by the myth—food jostling into the appendix after a meal and “infecting” it—is not how the anatomy works. /Vincent Pozon
