I had a terrible stomachache last night and ended up in hospital. I threw up once at home and I only puked the food I had eaten 20 min before. Later at the hospital I threw up what I had eaten for lunch. Why the first time I didn’t threw up a mix of both. How does the stomach selects what to throw up?

My wife always says that the body is wise and only expels what hurts you. Kinda right to think that way but how does it work.

The stomach really doesn’t ‘know’ what is causing the upset. There also aren’t any compartments that hold different meals. It’s basically one big mixing bowl (or rather, a bag) that gets mixed and mashed by muscles. What likely happened is, the stomach got upset (either by something you ate or an entirely different cause) and stopped mixing properly. Maybe lunch was compacted a bit more, so initially dinner came out more easily.
