eli5 why do you puke when sick

129 views

Currently sick and after puking I feel worse. Is there a reason our bodies do this? I feel like it doesn’t help because you lose nutrients and it dehydrates you.

When you feel sick, its usually because of something you ate, so to get the bad stuff out, the body forces you to puke, however, there are times where you feel sick, without having eaten the bad stuff, but the body is reacting as if you did.
It’s like a miss firing reflex? It is caused by the GI feeling irritated.
