Note: I am not la looking for medical advice. Do not remove my post.

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.

It doesn’t know, it just knows there’s irritation and kind of freaks out and starts tossing stuff out.

It won’t necessarily get everything in the first go, so if it’s still irritated, it may happen again, expelling even more

Sometimes this is triggered even when your stomach is basically empty, because all it knows is it’s irritated, so it may keep going even after it expelled the bad stuff

It’s like having an itch, which compels you to scratch it. You don’t really necessarily know why the itch is there, you just scratch and hope it works, and if it’s still itchy afterwards, you may keep scratching more. It’s possible the original cause is gone, but now it’s all irritated and may continue to itch for a bit

You wife’s answer is sweet, but our stomach’s are dumber than that
