eli5 why do you puke when sick

132 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.

If the sickness was being caused by something poisonous you ate, vomiting is a quick way to cure yourself. It could even save your life if the poison would have killed you!

Since the alternative is possibly dying to something you could have easily just thrown up, evolution has “decided” it’s a better overall strategy to throw up when sick just in case.
