eli5: Why does puking up food poisoning immediately make you feel better?

653 views

Is the food inside your stomach literally causing you the pain? Is that why almost immediately after puking you feel almost completely better? Why do you get so dang hot? What is causing all the pain anyways?

It seems to me like the food can’t be the mechanism of pain, but that’s the way it seems when you complete the awful act.

Asking as someone who just had a bad bout of food poisoning last night!

The nausea is from your body recognising the food as toxic. Basically your body can’t really tell whether a toxic substance is going to kill you, or just cause mild discomfort. So it’s trying to expel the substance before too much of the toxin can be absorbed into your blood stream. So once you’ve puked, your body sort of relaxes, it’s got rid of the toxic stuff.
